Summary: So, I chose the Corsair AX760 and I'm glad I did. It's absolutely silent and 100% modular. The only reason I gave it 4 stars is because it doesn't come with individually sleeved cables. Like it should.. Corsair.. Powers my system perfectly. If you have a similar build I hope this helps you.
Summary: Expensive, but a great power supply. I got a great deal on it and love it, but I don't know if I would pick it again over other power supplies in the same price bracket. Beyond that, this power supply is very nice. The cables are well done, its a platinum rated power supply, and Corsair makes a great product.
Summary: No reflection here on Amazon, because their return policy is excellent. I bought two of these to support a server build. The PSU has great specs, but other reviewers around the web had noted a lot of DOAs so I bought two in case one was bad. I guess I should have bought 3 or 4...
Summary: I chose the Corsair AX760 PSU for my third build and find its' an excellent performer. There is a post in the 2-star rating about a "Coil Whine noise" with this unit. I wrote Corsair Tech Support about this issue, and here's what they wrote back: "The noise is not normal to the unit. It's very difficult to test units for audible noise in reality, because Corsair's test environment has a very clean power source.
Summary: Hums, loudly. Contacted corsair support and their response was slow and primarily unhelpful. Returned. Replaced with an old pc power and cooling that doesn't hum. Every corsair PS I've ever owned did this, was thinking the top of the line model would be different.
Summary: I bought it because it is exactly the same as the (Seasonic Platinum 760W) but it was 10$ less and had a 15$ mail rebate so why pay more for the same thing? It's even built by Seasonic anyway so the choice was easy enough. When I said 760W is plenty enough it's because I still have quite a good amount of room with the setup below so why pay a lot more for only 100W extra with the 860w model?
Pros: - Not cheap but decent price at 160$ - 15$ MiR. Way too expensive at regular imo., - Platinum rating which is the best currently. Even if the "Titanium" rating exist, there is still no PSU with it yet and they will be way over-priced anyway for only +2% efficiency. It already took very long before Platinum get affordable which is why I had a (Seasonic X-760 Gold)., - Enough wires, flat sata/molex cables, long enough too., - Very silent even when the fan spins. You can...
Cons: - Umm, is there really any cons to such a good power supply? It is the absolute BEST power supply right now. There's nothing better right now and there's no need at all for anything more than 760 Watts as I'll explain below., - Edit: Actualy one small thing. It looks like they printed the labels around the cable slot on the PSU so it looks weird if I don't set the fan facing the top of my case even though it should actualy be facing the floor. Not a big deal though fo...
Summary: This power supply, I completely recommend it. It is modular so you only use the cables you need. It came with a whole assortment of cables in a nice bag. I'm really impressed with the quality of Corsair. The fan has 2 modes, full speed all the time or "intelligent" sensor based thermal solution. I'm using the latest and haven't had any trouble so far and the noise is almost null. I can't find any cons to this purchase.
Summary: This thing is quiet, no noise at all. In my computer, it does not reach the load required for the fan to start up so I hear absolutely nothing from it. I was initially a bit concerned after reading all the reviews about coil whine but I have had no issues. Fan grill may make mounting the PSU downwards a bit difficult depending on your case.
Pros: Quiet, 80 Plus Platinum Efficiency, Modular Cables
Cons: CPU power cable could be longer, SATA cables not sleeved, fan grill makes it difficult to mount facing downwards in case.
