From the Manufacturer

HX1050 hero

Quiet operation at low loads, modular cabling and 80 PLUS Gold efficiency makes HX Series PSUs a great choice for high-performance PCs.


Overview

Quiet operation at low loads

Basic PC power supplies have fans that spin whenever your PC is on – whether you’re pushing your graphics card to the limit or just surfing the web. HX Series power supplies are smarter than that: they generate less heat, so they require less cooling, and the thermally controlled fan only spins when it’s needed.

Slay the cable kraken

The modular cable set allows you to use only the cables you need for your particular set of components. There’s no more unwieldy mythical tentacled monstrosity of unused cables to clutter up the inside of your case.

High efficiency, low heat

Efficiency is the measurement of how well a power supply converts the AC power from your outlet to the DC power used by your PC’s components. If your power supply isn’t efficient, it will generate more heat, which requires more cooling and more fan noise. And, it might even affect your power bill.

HX Series PSUs are among the most efficient on the market. They help keep your PC cool and quiet, and your power bill down.

Features

Reliable and efficient operation
  • A dedicated single +12V rail offers simple configuration and maximum compatibility with the latest graphics cards and other components
  • 80 PLUS Gold certification, delivering up to 90% energy efficiency under real-world load conditions
  • The ultra-quiet, 140mm double ball-bearing fan delivers excellent airflow with exceptionally low noise levels by varying fan speed in response to temperature
Superior components for better performance
  • Active Power Factor Correction (PFC) with PF value of 0.99
  • Over-voltage, under-voltage, over-current, and short circuit protection provide maximum safety for your critical system components
  • Engineered to meet maximum power output at a server-grade 50°C temperature rating
  • High-quality capacitors provide uncompromised performance and reliability

Size: 750-Watts Verified Purchase
First off this PSU is rated #1 by many websites. The reason is simple, it outperforms any other 750w out on the market and on top of that its backed by a beastly 7 year warranty. The packaging is superb, the PSU comes in a nice black velvet bag and all your cables come in a very handy smaller vinyl bag. The PSU is protected by two large pieces of foam and some air bags. Corsair really made sure the customers would drop their jaws once thy opened the box, well at least I did a few years back..

I purchased this beast because I had a 7 year old Thermaltake 850w that could not keep up with my OC'ed x6 @ 4.2Ghz + dual GTX 570's in SLi. I removed the the old unit and installed the HX750 and now it doesn't crash when I overclock. Single rail, gold rated and fully modular, what more can you ask for? I have been buying Corsair products for years and I have ZERO complaints. You get what you pay for...

Aside from this awesome PSU, why is it that I see a few reviews below mine that have nothing to do with the HX750?. Amazon needs to fix this ASAP, this listing if for the the HX750 not the HX650. Combining reviews from 2 different products on one listing is just going to cause confusion for potential future buyers. Of course this is not the first time I have seen such errors on Amazon but it should get fixed ASAP, it's not good for business. My 2 cents..

PS : Not sure why the users below me purchased the 650 when its clear that Corsair had a bad batch.. Do your research prior to placing your order, a few more bucks and you could of had a 750w monster that is basically flawless.

As part of my odyssey to replace a Corsair TX650 that started to make a high-pitched squealing sound at idle, I was sent an HX750 replacement. Power delivery is unimpeachable, but this model has some acoustic quirks.

Let's put it in context first. The five general parameters for a PC power supply are efficiency, wattage, noise, size, and cable modularity. I'm rolling power delivery in with wattage; almost any properly assembled 'name brand' PSU over $50 will delivery consistent, low-ripple current at the correct voltage.

EFFICIENCY:

Fifteen years ago, most power supplies were about 70% efficient. For a 100W load, they would draw about 140W from the wall. Not anymore. We now have five major PSU ratings: 80 Plus and 80 Plus Bronze, Silver, Gold, and Platinum. These correspond to half-load efficiencies of 80%, 85%, 88%, 90%, and 92%. Efficiencies at 1/5 and 4/5 load are about 4% less than half-load.

This is an 80-Plus Gold unit capable of 90% efficiency. Relative to a Bronze unit like a TX750, for a 24/7/365 system draw of 200W, you could expect to save about $12 a year in power costs at $0.12/kWH. Efficiency has other benefits: namely, every watt that isn't going the system is dissipated as heat. Less efficient units may require a faster, noisier fan.

WATTAGE:

Power delivery in this 750W model is top-tier. Professional reviews have been uniformly complementary; stability won't be a problem for any system at any rated load.

It's not necessarily the best choice for many systems, though. Most power supplies have two general characteristics: they're most efficient at half-load, and half-load is when their fans start to spin. If you want a silent PSU, your maximum load should be no more than 60% of rated capacity.

I purchased the Corsair HX750 as a replacement for an old/faulty Thermaltake PSU and probably put a good 80+ hours into using it so far for work and gaming. So far I can honestly say this Power Supply was 110% worth purchasing. I own my own business in web development and programming. I also do a bit of game programming as well as music production. Bottom line, I know alot (more than the average user) about computers in general and I research to the death the parts I pick out.

PROS
- VERY quiet, shockingly quiet as a matter of fact! No noise during work and the fan stays cool even on "mild" games like Minecraft and Counter Strike:GO.
- VERY cool - even on Crysis 3 there is little to no heat on touch. The 140mm fan even on demanding games is nice and quiet.
- Modular cables, easy to route everything
- Beautiful packaging, design, and aesthetics, also noteworthy, a very thick quality cable to plug into the wall with
- On technical terms, this power supply is an "Active PFC" power supply. This means it uses a circuit to correct power factor better rather than using a capacitive filter. In human terms this PSU better utilizes the draw of power from your wall without wasting energy, while maintaining a better and more solid supply of power to the devices in your PC. This power supply could theoretically be pushed to it's 750 watt limit (or whichever you wattage you choose) and still stably run all of your devices without crashing from power failure.

CONS
- The cables aren't sleeved. Most cables are a nice, black braided cable, but the 24 pin connector as well as the 8 pin have those visible, ugly candy-colored cables. For my PC I already own beautiful Bitfenix Alchemy cabling to match my white PC case.
