I say keep the P2, for the following reasons:

- Restocking fees for returning
- The 750 P2 has a longer warranty
- The 750 P2 has much better ripple suppression

Reasons to send the P2 back for the AX760:

- The AX760 has slightly better voltage regulation
- The AX760 does better on efficiency, especially at an ideal load ~300W
- The AX760 has OTP, whereas the 750 P2 does not

Either way, both units are excellent. I just don't think there's any point in trading in one great power supply for another.

The ax760 for $94.99 is an excellent deal!


I settled on the evga p2 750w last week for $95. I'm contemplating sending it back in favor of this unit.

if you are willing to deal with the hassle of taking the computer apart and putting it back together again, then i think it's worth it. AX760 doesn't rely on in-cable capacitors for ripple suppression and performs close to titanium level efficiency.

it's also a little shorter, which will make a big difference if you eventually move to an mITX build

Is the ax760 a Tier 1 power supply? Would this be over kill with a i7-6700k and a nvidia 1080?

the "tier" thing is a bunch of BS. tom's hardware put some terrible units in tiers 1 and 2.

having said that, this PSU is as great a deal at this price and the performance is as goods as it gets. if you are running everything at stock speeds, it's more than what you need. however, since you do have an unlocked CPU, i'm going to assume that you will OC at some point. in which case this PSU is NOT an overkill.

you can step down to a ~600W PSU, but that will only save you like $15, at best.

I plan to overclock the CPU and GPU. I purchased an AIO cooler to help keep the temp down Smilie

in that case you definitely want the AX760. a basic system with a stock 6700K (no GPU) chews about 150 watts at full load. a stock 1080 is expected to consume around 180 watts. that's still speculation, but probably not very far off. a custom PCB version will probably be able to take more. and nvidia said these things will overclock like crazy. my water cooled 980 ti classified runs at 1600MHz core and 8300MHz memory, so i believe that.

so figure when everything is OCed, you're looking at 450W - 500W power draw, not factoring in any water cooling that you'll get for the CPU and/or GPU. fans+pump can easily do another 40 watts.

without OC, you'll be at around 50% capacity. with OC close to 75%. so this capacity should be just about perfect

Wow so the 850 is essentially 80 after the card and rebate?

The Corsair RMX/AX are quieter than the eVGA G2 (which is still a great unit). The Corsair RMX has lower ripple than Corsair AX and slightly lower ripple than the eVGA G2 (which is already very low).

I plan on picking up the RM850X.

the 2 together should only be 500w max power draw. maybe closer to 400 pascal is gonna be awesome.

If you are on the fence about this or any other computer deals just remember that we are nearing the end of the longest sale "drought" of the year. Other than Mother's day there are few/no shopping holidays between President's Day and Memorial Day ... and the lack of sales attests to it. Newegg's "deals" have been very few and far between lately. Here's hoping that this changes in the coming weeks. These PSs are overkill for the vast majority of us. Just my 2 cents ...
