Paid a hefty premium for this model, but I really liked that it's white and comes with white individually sleeved cables and some cable combs. Those extras sort of even out the increased price. Corsair had to cheap out somewhere though and didn't give any Velcro wraps for the cables.

Now let's talk about the voltage regulation. This unit has some TIGHT voltage regulation, very impressive. My vcore used to fluctuate under load with my EVGA GQ-650, doesn't budge one bit with this new unit. Was even able to push a slightly higher overclock thanks to the vcore not fluctuating at higher frequencies. I also like that the fan only spins at 40%+ load.

But the main reason this unit is so good is because Corsair didn't make it, they just slapped their logo and a new paint job on it(cream on the inside, clean on the outside).

Cables faded within a year, but it still performs well.

This was the splurge of my build but when you look at what I would've paid for individually sleeved cables on top of a power supply it's actually a steal. The cables are a bit stiff and they were too thin for the generic cable combs I bought.. but too thick for the combs that came with them. I got it to work eventually. I really like that it's white, even though you can only see it when looking at the rear of the case -- which is also white.

I have mixed feelings on this power supply and not due to the unit itself, but due to the cable combs and overall feel. It's great, don't get me wrong but the in the box combs don't fit properly and the construction feels a little bit on the cheap side. Otherwise if you're going for looks and you have their 570x in white.. this is it boys.

Corsair makes the best PSU, period. Good PSU with white color and more importantly the cables are white too. I know you can buy customized cables, but what you gonna do with the original ones?

Nice looking PSU that does what I need it to do. It passively cools itself extremely well, to the point that I can only see the fan spinning upon startup.

Very good looking PSU. Gets the job done silently and the cables look very nice.

Awesome PSU even if it is a bit overpriced. White "brick" (-Verge) is cool. White cables are awesome too. No need for cable extensions with this PSU. 750 watt gold rating is MORE than enough for "future-proofing" any systems I will build with it.

Silent, cool, supplies all the power needed. Images were misleading, I bought different cable. Still around the same price as buying the cheapest 750W 80+Gold PSU and cable extensions, so not too bad.

It is white. :) I am a Corsair fanboy and I love white computer parts. It is sleek, beautiful and does the job perfectly. Although it is more expensive than some brands in my eyes it's worth paying the premium for quality. This particular purchase wasn't necessary but when I was trying to go for a full Corsair build utilizing white parts I knew that the 750x or 850x had to be a part of my build at some level. I love it! My computer never runs on a high load so the fan in my PSU has not once turned on!
