5 out of 5 eggsGreat PSU, needs to be priced a little lower

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: nice PSU, I love Modular connections, really is more efficient then other 80% PSU’s

Cons: the size of the PSU is much longer than conventional ones, had issue with my Fractal Design Define R4, I had to relocate my fans, luckily I still had 120mm fans, As I had 140mm and that would not fit at all, with the 120mm fan installed last I was able to relocate the fan all the way to the HD cradle and made more room that way

Price is a bit high, could be a little lower and this would be clear winner!

Other Thoughts: The packaging was pretty cool, I never expected for such an item like a PSU would get nice packaging. I never like changing my PSU’s unless I have too, because it’s a real pain due to tucking all the wires and what not, it’s a major pain when not having a modular PSU!
Installation was more difficult because I had to try to find and relocate some fans, my 140mm would not work in my case and thus had to swap it with a 120mm that was in a different location. Once I tested the fan fitment and saw that the modular connections would work, I left the fan for last. Since my system has all the new power connectors and only very few peripherals I had used less then HALF! Of the connections and wires, so this made my wire arrangement so much easier! I do not game anymore but do 3d CAD/CAM work, so I have my trusty old AMD Phenom II X6 1090t @ 4.1Ghz, and for video an AMD firepro V5900, so no need for PCIe cables as this is single slot.

Now for testing, I do not care too much about the software side though it is a nice feature for this PSU, I wanted to know the power consumption at the wall!


With a killawatt meter I was able to see just that! This includes my 2x 24” LED monitors


OCZ GameXStream OCZ700GXSSLI 700W (bought in 2010) 80% PSU
Startup Max Watt: around 340w
Idle at desktop cpu 0-1%: 196w
Running intel Burn test 5 iterations: 455w


Corsair HX750I 80 PLUS PLATINUM
Startup Max Watt: around 320w
Idle at desktop cpu 0-1%: 186w
Running intel Burn test 5 iterations: 415w


There you have it, all around the board we have lower numbers then a more generic 80% PSU, note that monitors take probably around 30-45w both? So I am about 50% of the PSU’s power, If I want a more powerful cpu or graphics card I sure have lots more room. I believe I could have a few more watts lower during idle due to the fan rearrangement I did not change in the bios the % for the other fans, since I have different ones, with different power ratings, which could bring me about 10% difference from the OCZ PSU during idle, full load is only 9% but that could change as well with more load, as the OCZ one would not keep up in the efficiency.

5 out of 5 eggsIs it on?

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: Super, super quiet. - The fan doesn't come on at idle, but even when it does come on it's very hard to hear. (Unfortunately, my test card is a GTX 590, so short of a jet engine, nothing else is heard when the system is under stress anyway.)

750W of power! - Enough to give life to an i7 2600, 2 SSDs, a blu-ray drive, and the GTX 590 without breaking a sweat.

Great components. - Tough to beat the quality of the electronics inside this thing. I wish gaming PC companies used these instead of the garbage PSUs they ship. ($4000 PC with a $50 PSU, like using a cheapo rebuilt alternator in a Ferrari.)

Cables! - Modular and flat. These are AWESOME! So easy to run behind and around things. Sleeved cables look nice, but are sometimes fat and hard to place. If you don't like the flat cables, you can always sleeve them yourself. Plugging in just what you need is great as well. No extra cables to tie up and hide.

Extras - Zip ties, case badge, a nice hook and loop closure bag to keep cables in, and a velvet bag for the PSU itself. Very cool.

Cons: Price? Come on. If you have quality stuff in your PC, why would you cheap out on the PSU? Yes, it's a little more than a Gold+ certified, and more expensive than some other Plat + PSUs.

Other Thoughts: My spare Alienware desktop is my test PC for stuff like this. Usually it goes in, gets tested, and comes back out. This is staying in until I have to test another PSU. I've used Corsair RAM in my builds for years, and now I will be using their PSUs as well.

5 out of 5 eggs

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: modular

80+ Platinum

3xPCI-E connectors- I only use 2 but with it being modular, the extra cable isn't in the way but it's nice knowing the option's there.

power rating- 750W is plenty of power for most setups. I'm running an OC'd FX-8150 with dual GTX 460's, 4 platter drives, a SSD and various other accessories & the power supply isn't taxed at all. I'd feel comfortable running tri SLI if my 460's supported it. I wouldn't actually do that even if they did though, there are better options out there these days. GPU upgrades are in my very near future, they've served me well but it's time.

Corsair Link- This is new to me but I like that you can actually adjust the PSU fan to help with circulation. It also lets you monitor everything, it's pretty neat. If you have a spare USB header it's a neat feature. I like to monitor/tweak things so it'll help keep me occupied.

accessories- I love the cable bag and the fact they include zip ties. I have plenty of zip ties but I've seen too many PC's with great hardware and poor cable management. This encourages cable management for those that don't already have something for that purpose lying around.

Cons: Price- There's no question the platinum rating is better/more efficient than gold but justifying the cost when there's similarly rated gold PSU's for 2/3 the cost it makes the decision difficult.

Other Thoughts: With some finagling I was able to get the cables (they're flat) to lay snug against each other but the look is different than I'm used to. My case looks great but it took a little more work than I'm used to since I'm not used to running these type of cables. If you like to run your cables behind the motherboard if you have a case with an area that allows running them behind a wall of some sort (like one of my SilverStone cases) these cables will be preferred.
While I'm not the type to have a case full of lights, I made it a point that my case's status lights and light on my optical drive are blue. My case and everything in it is black so this power supply looks slick. It actually looks so good that I'm tempted to purchase a new black case with blue status lights that has better wire routing options. This power supply being black with some blue writing fits right in. I'm pretty sure I'll be looking for a case that suits me better when I replace these dated GTX 460's.
This power supply is easily 5/5 eggs if you don't mind paying the premium for the latest and greatest. CWT's high end power supplies are top notch. I have owned a few Corsair PSU's that were built by Seasonic but these newer CWT built ones are every bit as good. Corsair has been the only brand PSU's I've purchased in at least 5 years and I go through a lot of components between my own PC's, family, friends etc. I switched to Corsair because I've never had a failure with any of their products but I know they'll stand behind it if I ever do according to all the praise I've heard/read.

5 out of 5 eggsSolid PSU

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: * 7 year warranty for peace of mind
* 80+ Platinum (promises 90% efficiency @ 25% rated power, 92% efficiency @ 50% rated power, and 89% efficiency @ 75% rated power). Clean power, cost savings on the electric bill especially for 24/7 use.
* 62.5A combined for multi-GPU setups
* Modular design (fully modular, at that)
* Corsair Link monitoring functionality to check efficiency, temperatures, voltages in/out.

Having owned several Corsair PSU's (VX550, HX520, TX650, HX850, TX750V2) and recommended another (CX500), they are arguably one of the best enthusiast PSU vendors around. Even though their OEM's (builders) change from time to time, their products are always first class, built well, and supported by an excellent CS staff.

Corsair's PSU's used to be built by CWT for anything non-modular, while the modulars were built by Seasonic. Now it appears that CWT makes all of their units, including the HX750i.

Internal build quality is excellent. They use quality Japanese capacitors rated to 105 degrees C (221 degrees F). What that means to you and me is that internally, these are built to live long and stand up to incredibly hot temperatures/environment. Most PSU's have lesser quality capacitors rated for 85 degrees C (185 degrees F). As you are probably aware, as you load up your PC, your voltages and temps increase. These being built like they are, they can stand up to it and last long while doing so - they don't pop and blow and take out themselves (and possibly the rest of your system) like cheaper made units do.

Corsair Link is some pretty neat software. You have to download it from their site, and hook up the PSU via the included cable to one of your motherboard's built-in USB headers. It checks your PSU for readings for everything from wattage to efficiency, temperatures, and even fan speed. Using the software I was able to determine that on idle, my system pulls around 100W, with 'Power In' max being 177.2W and 'Power Out' max being 160.0W, with a Calculated Efficiency of 85.13%. This is using roughly 7.5% of the total PSU wattage. Max load while gaming, CPU & GPU combined, I got a 'Power In' max of 377.7W, 'Power Out' max of 348.0W, Efficiency of 91.5%. Honestly, I expected more than that being taken up; I don't have a Kill-a-Watt or wall tester to compare to, but I figured I'd be up around 550-600 judging from what the Extreme Outervision PSU Calculator Lite tells me I need with my system - roughly a 648W recommended for my system, which is:

* i7 4970K @ 4.4GHz (stock) [dialed in Vcc of 1.132]
* CM Hyper 212+ Evo
* Gigabyte Z97X-SLI
* 16GB (2x8GB) DDR3 1600
* Gigabyte R9 270 Windforce CFX
* Crucial M4 128GB SSD
* 3 platter drives (2TB Seagate 7200RPM, 1TB Samsung F3 HD103SJ, 4TB Seagate SSHD)
* 2 DVD burners

HX750i didn't break a sweat powering this system, and did so with superb efficiency to boot. Corsair has another excellently built, top notch quality PSU here. 7 year warranty is the icing on the cake.

Cons: Fully modular, I could take it or leave it. Some of these cables, you have no matter what - like the ATX 24-pin. I don't know what the idea is behind having this be a modular cable, because you're still going to need it. The idea behind modular is using what you need, not having to hide or cable manage what you don't need. I get the idea behind semi-modular (where the ATX cable is permanently attached), but I don't understand 'fully' modular.

The modular cables themselves, to be honest I prefer the standard bundled/sleeved cables to Corsair (and some other companies) doing this flat/ribbon cable variety. Oddly enough it seems like the bundled/sleeved variety is easier to deal with, cram, and hide.

The 'fan test' button on the unit requires depressing & holding in to actually get the fan to spin up - it's not a 'press it and it'll test for a few seconds' like you'd get with something like, say a smoke or carbon monoxide detector.

Platinum efficiency still has quite a price premium over a Bronze, Silver, or Gold unit.

Other Thoughts: I rate this PSU a 5 egg, unquestionably, because you are getting a 5/5 egg unit when you purchase one. Warranty and build quality are top notch. CWT has really stepped their game up, and Corsair puts out excellent products with fantastic support and quick warranty service if you ever do have a problem.

That being said, I think Platinum efficiency is still a little steep to choose over a cheaper/slightly less efficient unit like a Bronze/Silver/Gold. This is a great PSU, but if you're not as dead-set on the efficiency, you may be better served with a Bronze/Silver/Gold unit of similar quality and putting the money saved elsewhere in your system (better GPU, bigger HD, more RAM etc).

You do get what you pay for though, and again, this is a fantastic PSU. It 'feels' built well; it's heavy. If your PSU feels like a toy, it's probably built like one inside. The HX750i feels like a tank, and looks a little like one on the outside too, with it's rigid sides and thick steel body.

5 out of 5 eggsAwesomely Quiet

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: Fully Modular (Even CPU and 20+4)
4+4 CPU and 20+4 Mainboard start connected - can't accidentally separate

Test button for fan, to test PSU before installation

Includes both a link cable (which I haven't ever seen that connection before) and a miniUSB to 2.0 header cable

No sound from the unit - even at the heaviest load I could throw at it

LOTS of room for expansion, and there are PLENTY of SATA/Molex power connectors in-box

Cables are flat 'ribbon' type. They're MUCH easier to use, but are less flexible (but OHHH so much thinner)

Software allows you to see real-time performance data of the unit, and a trend of peak and lowest consumption

Cons: Efficiency <90% at loads less than 200w

Modular connectors sometimes difficult to secure to PSU

PCIe and CPU cables look similar on both ends - may complicate installation

Other Thoughts: First system tested:
ASRock M3A790GHX/128M
Phenom II x4 955 @ 3.61GHz
8GB DDR3 1333
Sapphire Radeon HD 4870 (PCIe 6pin x2, 80w)

Current system:
ASRock M3A790GHX/128M
Phenom II x4 955 @ 3.61GHz
8GB DDR3 1333
XFX Radeon R7 240 (no power pins)

This is an AMAZING PSU that, finally, some with MORE cables than you need! It fully modular so installation is easy, unobstructed, and allows you to either use your cable management system, or plan power connections to get the least airflow obstruction you can. I only had trouble getting the PCIe connection to stay in place during initial installation.

Fan: The fan has yet to come on for me during use. The unit creeped toward 40°c, but it wasn't high enough to trip the thermal limit for the fan.

Efficiency: this unit started at about 91%, but that was with a video card that took two power pins, and drew 80w from the thing. Unless I'm encoding video or crunching data (BIONIC or reviewing blockchains), it stays below 90%. Which is FINE for even a Platinum-rated unit. I average a 19% load, and that's at 88.5% efficient.

There's a tab for "System" that allows for the customization of your layout, but of course it only has Corsair cases (which I don't have - budget builder). It's straight forward and intuitive.

One setting I was confused about (and happy to find) was 'Multi-Rail Mode.' The product information says this only has a single, 12-volt rail. That can be BAD for people running a high-wattage CPU AND a high-end video card. This was enabled by default, and have yet to experience forced shutdowns (unlike a 'JermalFake' unit I tried for my first multi-core build). This unit will run a system with Fan Controller (three fans), 8pin CPU, two HDDs, DVD-RW, and a two-pin PCIe video card just fine. Just remember to turn up your fans when transcoding video or playing an intense game to dissipate heat.

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: PLATINUM Certified
Fully Modular (it makes a difference)
SATA cables of differing length
Monitoring software that seems useful
Software- Corsair Link - allows for user to upload their own case image.

Case badge !

Unit looks great !!

Forum

Phone Support

QUIET ! What?

Cons: Plugging in some of the modular cables is very difficult. I like to hear a distinct click which insures the connection is secure. The 24 pin ATX cable was particularly difficult. I have it seated but it doesn't look like it is. I had to apply more pressure then I would have liked

Boring black plastic zip ties. Another well known PSU vendor includes reusable velcro zip ties. I know because I just bought one. See my recent review here on Newegg

Manual should have had pictures and explanations of Corsairs nomenclature so I would be more sure where the cables plug in. It wasn't hard to figure out but I would have liked a cable picture and it's associated plug picture.

1 manual covers 4 PSU's and 7 languages

Corsair Link Digital Interface Cable ---> Nice line drawing on Page 3. BUT WHAT DOES IT DO ? Nothing in the manual.

Modular cabling is stiff and somewhat difficult to manage as pointed out in a previous review. In a smaller case it matters more then in a larger case.

Why do they pack these things in black crushed velvet velour bags like a bottle of whiskey?

Other Thoughts: Corsair sent me this PSU as a replacement for an HX 750 that failed. That was swell of them. Despite my list of cons
I like the PSU. If you want to get the nitty gritty (specs) on this PSU by all means you can I won't bore you here.

Corsair makes a fine product and their support IMO is first rate.

You can compare PSU's til the cows come home and if you want to split hairs go ahead. If you buy this PSU you will not be sorry.

5 out of 5 eggsLove it!

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: Well.. it's 80+ Platinum! Fully modular. When i first set it up i thought it was broken until i noticed it was dead silent because the fan wasn't even needed! It stays pretty low in temps. It looks really awesome with my color scheme i got going on. Corsair link enabled as well. It works like it should! 5/5

Cons: Only con i can think of ..are these cables that it came with...i mean,they work and all but they are stiff as can be. instead of being bundled and sleeved they are flat and side-by-side? It's kind of ugly to look at but w/e. For the price i thought i'd be getting better cables but i don't feel it's worth knocking an egg.

Other Thoughts: Overall i'd recommend this PSU 100% Especially if you have a blue/black color set-up going on.

5 out of 5 eggsWell engineered and quiet

This review is from: CORSAIR HX750i (CP-9020072) 750W ATX12V / EPS12V 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: The features are well engineered: full modular using flat low profile cables, 80 PLUS Platinum certified basically means it will be at a minumum 92% effieient, Japanese 105C capacitors, low heat, low noise. The ZeroRPM mode will keep the fan at zero speed until the load requires it to spin up, and then it is very quiet.

Includes Corsair Link USB cable for performance monitoring allowing the adjustment of fan speed and rail mode to single or multiple.

Supports ATX12V version 2.4 and EPS 2.92 standards, while being backward compatible with ATX12V versions 2.2, 2.31 and the ATX12V version 2.01.

Cons: The package does not include a cdrom to use Corsair Link, you need to download the software. The zip file contains a Windows install exe file. See the Corsair forums for the current threads on their "open support" for Linux.

Other Thoughts: The power supply self test works just the AC power cord, no need to hook up to a PC. The instructions state to press the button to make the fan spin, which it does for a brief second. If you hold the button in, the fan will fully spin up, allowing you to appreciate the low noise.

The Corsair Link flickers a LED during activity.
