Corsair AX860i vs EVGA Supernova P2 850W vs Seasonic 860XP2

post #1 of 7
Thread Starter 
I'm building a new Skylake system and the PSU is one of the last components I need to decide on. I'd like something in the 850w range and after reading lots of reviews here as well as JonnyGuru and TechPowerUp, I've narrowed my list down to three:
  • Corsair AX860i (Flextronics; $200 @ Newegg)
  • EVGA Supernova P2 850W (Super Flower; $150 @ Newegg)
  • Seasonic 860XP2 ($190 @ Newegg)

I've read lots of good things about all these PSUs (and, of course, some negative reviews, as well). Here's what I'm planning to use in this build:

i7-6700k
Asus Maximus VIII Hero Alpha
32 GB DDR4 (for video encoding, development and VMs)
GTX 980Ti (probably to be replaced by a Pascal-based GPU later this Summer)
Samsung 950 Pro M.2
Samsung 850 Pro SSD
2 TB 7200RPM HDD
Pioneer BDR-209DBK (either internal or external in USB 3 chassis)
Either Phanteks EVOLV ATX or Corsair 750D Airflow Edition

I don't think I truly need 850w but I'd like to have the extra power because I might add another GPU and/or some other components in the future. I'm ok spending $200 if the Corsair is worth the price and justifiable over the other options. So, with all that said, is there anything that would cause you to *exclude* any one of these three PSUs from the list? Thanks very much for your thoughts and suggestions!

The EVGA PSU is by far the best one. Don't look at customer reviews, look at professional reviews written by experts, like the expert reviewers at JonnyGURU.com. All three are very very high-end, but the EVGA has the lowest price because EVGA is ok with their good PSUs being their loss leaders! Their losses are our gains in money saved. The other companies like Corsair and SeaSonic just want to make as much money as they can.

In terms of performance the AX860i is the best. The only thing the P2 wins in is the ripple. I linked the G2 version as its based off the same platform. All three are excellent PSU's. Grab the G2 as the P2 is not worth the premium over it. If you are still undecided you can check out the RMA experiences between the companies to decide which one you want. But seiously get the G2 version. The premium of platinum rating is NOT worth it.

Unless we're talking about taking this rig to professional world championship overclocking competitions, we're splitting very fine hairs.

I agree that the P2 is not worth the extra over a G2.
If better efficiency is a must move to the T2 instead.
