Quiet: fan rarely spins
Great price on sale q $130
Solid build, great fan (definitely looks industrial) and only spins up on load, fully modular, single rail = good buy especially when on sale

Experience: 90 Days
great quality power supply
none if on sale
one of THE best power supplies out there.fully modular withnice flat cables.

Experience: 2 Weeks
 Verified Owner
Single rail, modular
Odd 24-pin connector, one too few 6-pin PCI-E, pricy.
The AX750 is a great PSU for those who are looking to do crossfire or SLI and want very high efficiency.

The single rail design is ideal but the 24-pin connector (on the PSU end) is a little strange with it splitting into two awkward connections. Finally, I would have liked to see an additional PCI-E 6-pin cable.

Overall, solid product.

Experience: 2 Years
powerful, and quiet
expensive, and the AX760i is available now, which is worth the extra bit of cash
Easily one of the best PSUs in the class. Mine is extremely quiet, and looks damn good. The cable quality is top notch, and the sleeving is very good. Corsair gives you lots of cables and stands by their products.

HOWEVER, if you're thinking about getting this one today, and have the money, get the AX760i. It's a little bit more but that extra efficiency will save you the money in power, and will get you a better power supply. I got the AX750 back when the AX760i wasn't available, but if I were to get another one, it would be the 750i, no question.

Great Performance
Good Warrenty coverage
Works the way it's supposed to.

Experience: 1 Years
I'm Bi-est think the world of the company.Have been buying thier products since I got into computers some 25yrs ago I belive. Complete modular meaning you can use the wire want. They have adaptors included for extra older or newer productes that require a different or expanded applications.Truely more power then what is needed for todays computering.
You probly will never use all the wire or adaptors that come with this moster.
Have left over screws,nuts,wire,adaptors that have a stylish blackcloth case to put them in. The box is perfect for storing other parts, and case pieces in.Just a wonderful supply unit thatI use for 6fans,gaming card, pci-SSD card,$Blu-Burners PLus ext.Burner and TB harddrive plus after market CPU cooler.With power to spare.

one of the best psu
I bought this on discount and I think this is the best invested I've made so far in my PC. I mean you probably would change your cpu, mobo, gpu every two year. But having a nice psu, you will never need to replace it again. In fact this psu has 8 yrs warranty, and it is made by one of the best psu manufacture - seasonic. A one time investment is really worth it isn't it?

-Fully Modular
-Gold Certified
-Black sleeving for cables
-Great packaging
-Has a case badge
None whatsoever
Got this power supply to replace an old one I had. Let me just say this PSU is sexy. All black cables are very nice. Fully modular so makes cable management easier. Gold cert so it's very efficient. Well packaged so you know it'll get to you in great condition. Highly recommend this PSU and would definitely purchase again.

Modular, Gold certified, energy efficient, warrantied.
You need to pay to get such great quality.
This is an high end energy efficient power supply that gives you 750 Watts to plug in your favorite latest devices: video cards, hard drives, SSDs, etc. You will probably have more than enough power for a gaming rig or a mainstream business PC.
