5 out of 5 eggsFantastic

Pros: Absolutely runs a high end CPU and GPU. No problems or hiccups.

Cons: Overclocking GPU and CPU can put a bit of strain on this PSU, however it still manages to keep up.

Other Thoughts: Rosewill is the only way to go.

1 out of 5 eggsIt seemed like a good deal at the time

Pros: Good ratings, reviews online, working well in my son's system (so far)

Cons: Delivering inconsistent performance in my system, possibly the cause of hardware failures..

Other Thoughts: I bought two complete sets of nearly identical components from newegg to build two new desktop PCs with my son, one for each of us. Among the components was this 650 watt rated rosewill power supply. After having built our PCs and installed Windows 8.1 on each, everything seemed to work great, for about a week. then the ethernet controller on my Asus Z97-A speed working, with a Code 10 error. Nothing I did changed it. Meanwhile, my son's system continued to work just fine. Wanting my built in ethernet to work, and deciding to go for a full on upgrade/replacement motherboard (thinking it was to blame), I installed an Asus Z97-Deluxe. In only a few days, the system began to freeze at the Window 8.1 swirling does screen. So I removed all usb devices but the keyboard and mouse, and removed the GTX 970 video card to test in a minimal setup. Tons began working again. I placed the video card back in, and things continued to work.. Strange.

Two days go by, and suddenly the wireless AC adapter on the motherboard fails, again with a Code 10 (the pc was on a table away from an ethernet cable whole I was testing for the previous issue to recur). I pulled the Asys Thunderbolt card that came with the motherboard this time (no decodes for it yet anyway). Suddenly everything magically worked again. Until the next day. Removing the video card again, booting, shutting down, and reinstalling it again fixed the problem again.

After this I stated looking at the Windows error loss, and found several kernel power error 41s in the log. Looking this up, it means the system powered off unexpectedly, and without enough time for windows to properly shut down. I'd let the system on since starting all of this troubleshooting, so it wasn't ME flipping a switch or holding down the power button.

More research on the MS site indicates that this can also be caused by a bad or failing power supply. Given the fact that it's intermittent, multiple different pieces of hardware are acting up at random (not much software installed yet either, office, steam, and Origin, along with elder scrolls online, that's it), I can only conclude that my power supply is bad, and has been causing my problems.

I can't afford a replacement until next month, so for the meantime, the system is being left off, to avoid actually killing any hardware (a potential consequence of a falling PS).

So, regardless of the ratings, and Eben of the fact that my son's is still going strong, I don't recommend this product. Disassembling and reassembling a pc several times for apparently random unconnected hardware issues is not fun, and shouldn't be an issue for a product with an 80 plus Platinum and 650 watt rating (with no more hardware than I currently have- note that the issue isn't even occurring when my video card is under load, it's apparently while idle or waking from sleep).

4 out of 5 eggsGood PSU

Pros: Worked fine out of the box and I have not had any problems with it yet. Plenty of cords so everything is easy to connect.

Cons: When I start my computer this power supply makes a clicking noise for the first couple minutes until it warms up. There are so many cords that some of the unused ones get in the way

4 out of 5 eggsClean, quiet, easy

Pros: - Inexpensive
- Very high efficiency rating
- Connectors for every modern (and ancient) motherboard or peripheral.
- Screw holes are in the right places.
- Includes nice thumb screws.
- Cable sheaths are nice
- Includes "cable management" accessories (velcro and zip ties)

Cons: - You're going to need somewhere to stuff all those spare cables/connectors. There are 14 4-pin molex or SATA connectors, along with a handful of GPU power, floppy (?!), etc.
- Cables are stiff
- Not enough distance between SATA power connectors. Just barely couldn't route around a GPU because the connectors are so close on the cable.
- Not modular. I knew that, but goodness there are so many cables. Where are they all supposed to fit!?

Other Thoughts: Overall really pleased with this, but so thankful I had 3 spare 5.25" bays, because that's about how much room all the extra cables took once I wired up my motherboard, 4 fans, and two hard drives. Seems to do the job cooler and quieter than my old 500W PSU. Would buy again for a "spacious" build.

3 out of 5 eggsunstable power on overclock

Pros: Heavy, efficient, tons of wires. Very quite and able to power a i5 at 4.5Ghz, mulitple ssd's, a blue ray player, 16GB ram, and a R9280x

Cons: At high overclocks on my CPU, the power supply to my graphics card would fluctuate wildly. Though i have no voltmeter, the GPU (at stock conditions) would constantly reach 100% fan load and idle at about 60%. when I dropped my overclock on the CPU, the GPU never again went above 80%. This, combined with constant bluescreens during voltage spikes (ie idle to stress and back again) makes this an unreliable choice for "higher level" overclocking.
Also, there are tons of cords attached to this non-modular unit, about 3 of which I never use. Next model will definitely be modular/semi-modular.

Other Thoughts: Very good operation under basic conditions. just doesn't pack the punch needed for "hardcore".

5 out of 5 eggs

Pros: I have had this PSU for almost a year now. I used to think Rosewill was entry level junk, but this PSU is fantastic. All the power I need for a crossfire X setup, 3 hard drives, and more fans than I care to admit. Even through dirty power situations (brown outs and black outs that occur relatively often in my area) this PSU has survived.

Cons: Not modular, but I knew that when I bought it.

4 out of 5 eggs

Pros: -Great continuous power
-Energy efficient
-Sleek design

Cons: -Not modular

Other Thoughts: Not being modular would not be an issue, although the cords are stiff so tough to work with when managing wiring in the cased, if this was not the case would have been 5 eggs from me

5 out of 5 eggsRosewill Fortress 650W Single Rail Platinum Certified

Pros: I am old school about PSUs. I normally would buy name brand, Antec, Cooler Master, or Corsair items because i try to reduce the margin for error in my PC builds. Now Rosewill a few years ago I would of considered a GENERIC brand. They have proven me otherwise with their Cases *which i bought a Challenger case along with this PSU, which i love*, their peripherals, and now their PSUs. I had a Thermaltake dual rail PSU TR2 600, it powered my new Haswell build up but i got blue screens from returning to sleep in sometimes in boot and during high loads in games. Now my ATI 7950 was pulling real power, and my previous Thermaltake couldn't handle it. Not to mention the new Haswell low power sleep modes, it coudln't handle booting back into Windows from sleep mode. Not to mention i just dropped 500 on a MB and CPU about a month ago, and to get blue screens on your brand new setup i was not happy.

After using my new Rosewill Challenger tower to put this Fortress 650 in, i put my Astek Fatal1ty and 4670k into it. Along with my kingston 128gb SSD and 2 TB Seagate with my samsung SATA DVD writer. I was worried again about my MSI 7950 pulling too much power. Everything booted up perfectly. No blue screens, can return from sleep fine now. Couldn't be happier with this PS. Most gamers have these wacky ideas they need 800w - 1000w PSU for their setups, if u boil it down to the math its just not the case. I got lucky and paid 90 bucks for this unit, and I couldn't be happier!
Thank you Rosewill, you have a loyal customer!

Cons: Not Modular, I knew that when purchasing, big deal!

Other Thoughts: If you don't understand PSUs u should really research this stuff before dropping the money it takes to get a real PSU. Lemme tell u though, if u have a moderate power pulling Haswell setup like mine, this is the PERFECT PSU. Platinum certified too? COME ON!

5 out of 5 eggsSo far, couldn't be happier

Pros: Unless you've got a really over-the-top build planned, this is all the power supply you'll ever need. It is built using top-notch internal components, and as a testament to that you can actually pull slightly more more than the rated 650W from it in the real world. I'm running an overclocked i5-3570K with two AMD Radeon 7970 graphics cards in Crossfire mode on this power supply. I use my video cards to mine Bitcoin/Litecoin when I'm not using them for anything graphics intensive, and with the CPU and GPU's running flat-out, I only draw about 600W from the wall based on my Kill-a-Watt meter readings. (When I overclock the video cards I've actually exceeded 650W a few times, and the PSU didn't skip a beat. There is more than enough headroom in this unit for a very high-end build.

The cables are nice and sheathed, I didn't have any problems with cable length in my Fractal Define R3 mid-tower case.

The fan in the power supply is quiet.

The four PCI-e leads all have 8-pin capability.

up to 94% efficiency (80 plus platinum).

Crazy (awesome) 7 year warranty.

Cons: When it's running near its rated load potential, the unit gets pretty hot... perhaps a side-effect of the quiet and conservative fan.

Other Thoughts: This PSU has survived several rounds of annoying brown-outs and power outages in my area. I would buy it again.
