Pros: Did you know Rosewill is Newegg’s house brand? In the past (years ago) I was more judgmental of the name. I can say I have used many Rosewill labeled products with complete satisfaction, but being truthful, it wasn’t always rainbows and unicorns. This power supply is probably the first Rosewill branded one I have used in a long time, and in short, it has turned my eyes back to the affordable great performance backed by a company that I truly do believe cares about its consumers. The next part to this preface is where we see the dedication and turn around both from Newegg and Rosewill. If you didn’t know this, I hope this educates you and places newfound confidence in the product you are looking at (I feel for the other reviewers, but I also believe it was simply unfortunate luck that lead to their reviews reflecting sub-par and poorly). Rosewill’s G1200 Capstone is none other than an Enhance PSU. Enhance is an OEM manufacturer that designs, collaborates, and works with companies to produce some of the best power supplies across some of the top brands (Antec, Cooler Master, Zalman, and most notably Silverstone). Enhance is also known for making leap-forward improvements (they listen to feedback and actively aim to produce better power supplies). This reviewer personally rates Enhance as one of the top PSU manufacturers when you need something that will keep trucking. Seasonic (Some Corsair/NZXT Hale models) is my all-time favorite OEM PSU manufacturer, followed by FSP (some BeQuiet!/Hale models) but these are often unfriendly choices to our bank accounts. If you have ever wondered about what PSU you’re actually using you can check the UL number on the label, but most OEM manufacturers proudly put their names on internal components visible through the grille. The Rosewill Capstone G1200 is a beast of a power supply beyond the needs of most of us. It has a design for some seemingly specific styled applications I’ll cover in this review, but can be applied to accommodate everyday use with ease. It isn’t the prettiest PSU to showcase, and while it’s semi modular, a lot is left to be desired when you notice the ugly ketchup/mustardy look of the horrendous, and in most cases visible, 24 pin connector. The rear vent is covered, but inside are bright ugly components like capacitors. I have seen a neat tactic in some PSUs where it’s shrouded inside with a tinted plastic to make it less of an eye sore. On that topic however, it’s not like people will be gazing fondly at the rear of the PSU. And it’s not that the PSU visual aesthetics are the most important things in the world, but the whole enclosure seems to be a little dated feeling, everything from wording on the back, to design choice, to style implementation of the 24 pin cable. It’s likely intentional that it doesn’t attempt market appeal beyond what it is. The power supply is rated 80+ Gold by the EPRI standards, and in theory under different loads should always operate above 80% efficiency or better. The modular input panel provides a large amount of diversity, but notably supports power for dual CPUs (color coded), either same board server board, or a neat twin board set up idea in theory. I felt this PSU would be best suited in a moderately demanding home server style application (I know right? Unless you run a twin socket power hog home business, it likely won’t see that sort of use). All aspects of its design make this reviewer feel this way about the Capstone G1200. Of course this does not limit it to only be used this way. For the price, with the gold rating, it’s hard to pass up considering it for enthusiast builds. Rosewill is a brand that used to fall in the middle for me, and while it will take time to fully test dependability and reliability of this power supply, for now it seems to be a pretty great choice. Some Alchemy extensions should take care of the ugly 24 pin, and the non-needed cables will not be used saving some cable space. It’s sort of like Corsair’s CX###. Deal with a little bit of ugly for a good price, and find a solution for the bad.

Cons: As I have sort of touched on above, some of the cons are (for now at least) the dated style, and the ugly 24 pin connector. Over all I have had no major issues with the PSU, it isn’t as quiet as I thought it should have been with a 135MM fan against such restricting grille. It operates and functions fully as I anticipated, but I am wary of other reports involving the Capstone series having failure. If I encounter any issues I will amend my review to properly reflect any issues, as well as the customer service experience. The lack of support, short of alchemy extensions, for customization is a bummer. While it is a bummer, it should be considered this is an exceptionally priced, work horse PSU, by a brand (Rosewill) owned by a company that excels in customer satisfaction (Newegg).

Overall Review: For now, I would recommend it as an alternative idea to the far more pricey. To me it is a bargain find given the OEM is Enhance, and the price is fairly awesome for all that it has to offer. Most enthusiasts will set their sights on a higher, more popular, flashier and more expensive option, but at the end of the day this semi-ugly duckling would be my pick. I hope not to encounter issues, as of course anyone hopes not to encounter issues, but if issues arise I will update about it. Until then my review stands firm. This is a lot of power supply, from a reputable OEM, sold by a subsidiary of a company I whole heartedly trust and has never failed to resolve my issues. I will continue to try Rosewill products in the future on my own dime, I want to love Rosewill but they truly have been hit or miss for me in yesteryears. I’m hoping the Capstone G1200 will continue to be what I feel it is now. I have my eyes open for the issues the other two previous reviewers have mentioned. As I stated I will update if I encounter an issue.

Pros: After having several power supplies in a row from other brands with moderate to bad coil whine I was excited after booting this one up and not hearing any from this unit. That alone makes this power supply a definite keeper. With 1200W it's got plenty of power for even the most demanding hardware. I was also impressed with the sheer number of devices the included modular cables can support. Out of the 10 modular sockets on the power supply itself I only ended up needing to use 3 of them to power 1 HDD, 2 SSDs, a nVidia GTX 1070, the Motherboard and CPU, and a fan controller. So I've got plenty of cables (and power) to grow into. I can't hear the fan on this unit at all, at least not over the other fans in the system. The 80 PLUS Gold certification is definitely appreciated, wasting less power and saving you money on your electric bill is always a plus.

Cons: The CPU power cords were a little bit short if you're into good cable management. If they were an inch or two longer that would have been great. Everything else seemed to be about the perfect length. The main motherboard power cable is also really thick and isn't flat like the others. Minor complaint, but the cables were a bit more unwieldy and less maneuverable than those of other brands.

Overall Review: This power supply also has the ability to power two CPU sockets, a must-have for some people and a non-item for most. But if you want to run two CPUs, this thing's got the power you need.

Pros: - 80 Plus Gold certified - Modular - Quiet even under heavy load - Seems to run cool even under load - Black makes it look really nice if you have an already black case - PLENTY of SATA plugs - DUAL CPU ready (note not dual core, but actual DUAL CPU socket ready) - Single +12V rail

Cons: - The motherboard power plug is more "standard" looking making it look somewhat out of place given that the rest of the plugs are a clean black look

Overall Review: Honestly I wasn't sure what to expect with this PSU. I typically prefer Corsair but was open to the idea of Rosewill again. I've owned a few of their products before and while some are deservedly so cheaply made, I feel like their top end stuff is much better than it used to be. I appreciate the effort to bring some quality to the value space. Honestly the PSU worked perfectly. My test system includes a Core i5 3570K CPU and 16 GB RAM with one single Samsung SSD an MSI motherboard and dual GTX 960s and a test with a single GTX 770 4GB. I ran multiple stress tests and tried to maximize the amount of draw. Everything ran stable with no issues. I am pleasantly surprised. The PSU also has Dual CPU power available for dual socketed systems. By this I mean it has two separate cables of CPU 8 Pin plugs available, not just one cable that splits the 8 into 4. For those trying to build a server or maybe a beefy workstation this thing should be able to handle it. The modular cables have ports in abundance. The SATA cables alone make me want to switch this PSU into my server where I have many data drives. The warranty is 5 years which for most people is plenty and is average-above average in this segment (some have 10 year warranties). All in all it was a pleasant experience working with this power supply. I wouldn't have any problem recommending it to my family or friends if they wanted to save a little bit of money.

Pros: Modular is a must for me, to allow better airflow. Less spaghetti is better since I only use what I need. My rigs are used primarily for Video storage, editing, and media recording. I don’t game. This PSU has all anyone could want or need to game with multiple displays. SLI and Crossfire compatible with more connectors for GPU’s than you can shake a stick at. This is primarily designed for serious gaming rigs. A lot of wattage for your cottage. I can burn several DVD’s or BR’s at a time with no overheating, no hiccups, or spikes on my core i5 rig with 16GB Ram. Air cooled with a HyperX 212. I use SSD for Win 7 64 bit Pro OS and 2 large internal spinners for storage. Cool and quiet. I think my case fans are same or higher dB as the PSU. Hard to differentiate with case all buttoned up. Quiet operation is a must, because my PC is in my main common room. This is as good or better at maintaining lower noise levels than many other PSU’s I have had. Gold Plus efficiency is a big pro, as I leave my system on 24/7 unless I go on vacation. Single 12V rail gives me confidence to not sweat overloading like with a split rail PSU. I have no clue if anyone really needs 100A on their 12V line, but it’s there if you do. I am guessing for eye-finity display banks this would be very well suited. Value: Where else are you going to get this much bang for your buck? Fit and form are all within normal specs. No issues there. Build is solid. Glad for having so many SATA connectors. I use every available SATA port on my Mobo.

Cons: I cannot think of a con. It only sips what it needs. Better to have the extra power and not need it all, than to need more than you can deliver and risk issues.

Overall Review: This even comes with a floppy connector for those of you with legacy Mobo’s, And 4X Molex for the tweeners. This is a winner!

Pros: Great quality and build Great price point for a good performing PSU Black color matches most PC builds Super quiet operation, good fans (135mm) and comes with AUTO fan control for optimal performance 1200W Total Power - way more power than I ever will need! SLI &/or Crossfire Ready 100 amps is (in my opinion) plenty for just about any kind of build imaginable 80 PLUS GOLD Efficiency rating Modular Design - plug in only the wires you need! Helps save on the amount of cabling throughout your build. It comes with pretty long cables Has a lot of SATA cables for HDD's and various drives (CD, DVD, BluRay, etc.) Comes with big enough screws to mount the PSU (thumb screws) Single 12V rail design means no load balancing issues - stable and great for video gaming systems 5 Year Warranty!!

Cons: Not enough Molex connectors, that's my only gripe. I had to get additional adapters to get more LED lighting throughout my rig.

Overall Review: If you're in the market to buy a power supply just once, for the next 5 years, then this is a great CPU option. Unless you're "trying" to overload it, for a regular PC, this PSU can handle an awesome gaming computer, workstation or just a regular day to day PC. I especially like that there are lots of SATA connectors so you can just plug in additional hard drives or SSD's as you wish in the future. By far, this is the best PSU I have ever used for any of my PC builds. It's actually a bit too much considering that GPU's, CPU's, HDD's, SSD's, etc. are so energy efficient already. So far, I've used it for over 2 weeks now. I do a lot of video editing and graphics on this PC and it's literally turned "ON" 24/7. I have yet to see anything bad from this PSU. I'd highly recommend this PSU! On top of that, Rosewill is offering 5 years of warranty and the price is right for this type of product! Well worth it.

Pros: • Gold efficiency rating • Really long cable strings • Plenty of SATA cables • Basic black for stealth cable action • Thumb screws for the PSU mount (nice touch!) • Single rail design means no load balancing issues • 100 amps is plenty for just about any build imaginable • Price is solid for a good performer • Warranty is excellent

Cons: • Strong chemical smell out of the box; feint chemical odor after being on for a while • Flat sealed ribbon cables = not a PSU for a sleeving project • 24-pin isn’t sleeved to the end (not attractive

Overall Review: The Capstone G1200 is a great package, delivering plenty of gold efficiency power for a seriously budget price. Like hard drives, PSU’s are as good as their warranties – 5 years on the G1200 tells me they think it will last. I appreciate the single rail design with load balancing across multiple rails potentially being tricky, especially if running light on the CPU/heavy on the GPU’s. I also like that Rosewill has went heavy on the SATA strings, giving you plenty to use across multiple hard drive setups, and some motherboard auxiliary power ports (Gigabyte uses SATA ports on the vast majority of their mid-level on up boards). The minimal Molex count works for me because I use fan controllers loaded with 3-pin connection points, but might not be so good for folks that like to run their fans right off the PSU Molex string. Budget PSU, so there will be some concessions. Overall build is nice and clean. Little light on the paint (scratches easily, so install carefully), and a quiet 135mm fan. Cabling is the one area that doesn’t work for me, but not the fault of the G1200 (it is exactly what it says it is), with an unattractive 24-pin, and flat, sealed peripheral strings that you can’t take apart and sleeve. You mitigate that by picking up some NZXT or Bit Fenix cable extensions, and then stash all of the boringness behind the mobo tray (or under the PSU cover, like so many cases now include). Being a budget PSU, you immediately notice the strong chemical smell when you pull it out of the plastic. I’ve noticed this with nearly every budget PSU (excluding Corsair Builder Series; have never noticed the smell), and it always fades away with use. Almost like the generated heat “cures” the paint job. Outside of those couple quibbles – nothing else to complain about. The Capstone G1200 is a perfect foundation piece for a stripped-down powerhouse. The low cost allows you to purchase cable sleeving extensions if you want things to be extra pretty, and the single rail design dares you to load up nice and heavy on the components. The gold efficiency rating means they didn’t just throw out some numbers while testing in a refrigerator, so even more to feel good about. Highly recommended for the builder who wants quality over frills.

Pros: Nice sized power supply and should fit fine even in smaller cases. Modular design. 1200W power is more than most users will need. Gold power rated. Single 12V rail. Quiet fan.

Cons: The 24-pin Motherboard power cable is hard-wired and not modular. Burning/Chemical smell for 1 week of first use. Electrical buzzing sound when under load.

Overall Review: Overall this would be a great power supply if it wasn't for a few issues. First of, the good... I installed it in my 4 year old PC that I built, and it actually replaced a 10 year old Enermax NoiseTaker 600W power supply that still works without problem. This Rosewill 1200W supply is still about the same size as the older Enermax 600W, and always about the same weight. One thing I noticed is the external case metal of the Rosewill power supply feels a bit thinner and cheaper quality, and looks like it is just spray painted black. My old Enermax has a nice dark pearl blue color and is thicker metal. Installing the new Rosewill was easy, but wish the motherboard cables were also removable and that would of made for better cable management in my case. All the rest of the cables were fine and I like the long length, but wish there was a 2nd 4-pin Floppy connector (I have a Sound Blaster drive bay that uses a floppy power cable). Now for the bad... Once I powered it on for the first time, I could smell something coming from the Rosewill power supply. It smelled like a burning chemical smell (not that anything was burning or on fire). After a period of time this smell became less, and now a week later it is gone. I think this is "off gassing" that I've experienced before with some lower-quality electronics when new. But my other issue is that when the system is under load, such as rendering video using Sony Vegas, or playing a game (which I don't do often), the Rosewill power supply will start to make a high-pitch electric buzzing/harmonic sound. It isn't super loud, but I can hear it (about 5 feet away) as it is very high-pitch. I think this is coming from either a capacitor or a transformer, again being low-quality. My old reliable 600W Enermax never had any of those issues, and has lasted 10 years. Even though this Rosewill 1200W has a 5 year warranty, it just doesn't seem to be good quality that will last over time. Because of this, I am rating it 3 out out of 5.

Pros: -Modular with long cables and plenty of watts for any GPU doubt anyone will have any 'powering off' issues with this PSU. -Four 2 foot PCI-e 6+2 pin cables so plenty of (if not too much) length and all 8 pin. -15 SATA power connectors 4 Molex and one floppy. -About a foot and a half cable then 6in between each molex and sata connector. -Most powerful single PSU I've had so far.

Cons: -I think it could use a few more molex for fan's and other accessories. Only 4 molex then 15 sata is a bit excessive if not weird and that's coming from me when I actually have 7 HDD, an SSD and 2 DVD drives. In my opinion one or two of the 5x sata cables should have been a mix of sata, molex and another floppy connector. - Only 16 gauge higher amp wires (CPU/PCI-e). This is a con for me more specifically since I've had some 16 gauge wires run hot & not be enough for older high power AMD dual gpu cards such as the 6990 or 7990, It's unlikely people will use those as often nowadays though. -The 2 foot PCI-e cables. I assume two feet is almost always going to be too much. Yeah it is always better that its too much than not enough, which is likely what they aimed for. However for me personally I didn't need 1/4 of that length. -Still not powerful enough to run my desktop alone but that's not bad considering I need 2kW and use 2 parallel PSUs to power it normally.

Overall Review: Hard to come up with much else to say, it runs warm and quiet but not too hot. Haven't had issues under load and been under heavy usage for 2 weeks without powering off my system (I never turn my desktop off). Heck I even tested it with a multimeter just hoping to find something off (There wasn't.), all just so I could have something to talk about since this is supposed to be a extensive review. It'll definitely be great for cable modding plenty of amps for it and if you're into that id recommend upgrading the fan just to help with heat since this is rated to run at only 40C which is lower than most PSU's. Only other thing I can say is it's a great PSU for the price and it works as advertised so far and I haven't had a single problem yet,.
