Need help on deciding. OCZ vs Corsair

So I'm upgrading my computer and I was thinking maybe upgrading my PSU too so I won't have to later on since I'm thinking about running crossfire/sli in the future and maybe adding a few hard drives in.

I've come down to these two choices:

and

http://www.newegg.com/Product/Product.aspx?Item=N82E16817341045

I'm having a hard time making up my mind between these two PSUs. These two PSUs are both fully modular, they're both 80 plus gold, and both have at least 5 year warranty (even though corsair has 7). They're both around the same price, but the OCZ one has 150 more wattage and cost $10 more than the corsair PSU. So which one would you guys choose and why? (Regardless of the warranty) Thanks in advance.

  1. Corsair. Stay away from ocz units, corsair units have much better quality
  2. The OEM of the ZX series is a company called Great Wall. They have not established a reputation when it comes to build quality. But the OCZ does perform very well, so I don't think the OCZ is a bad choice, just not one that I would make. The main cables on the OCZ are only 55cm long, which is not ideal in a build that needs that kind of wattage.
    So I think I would choose the Corsair AX over the ZX.

    However this is another option:

    What is your system? Or what is it going to be?
  3. Question: OCZ or Corsair?
    Answer: Corsair
  4. The AX 850 is made by Seasonic... Seasonic is an excellent manufacturer of PSU's. Go with the Corsair.

    Here is a review of the AX 850:

    Here is a review of the OCZ 1000:

    In general the Great Wall reviews have been getting better, however the general track record of Seasonic is better. I don't think either one would be a bad choice.
  5. I would go with the OCZ ZX Series 1000W (OCZ-ZX1000W) for its +12 Volt continuous current rating of 83 Amps because it has the ability to handle more power hungry graphics cards. It will even handle 3-way SLI or Crossfire since it has six (6+2)-pin PCIe connectors.
  6. Let's say I decide to crossfire like two 7970's (possibly 4 way crossfire or 4 way sli if I choose to go with NVIDIA) along with 3 or 6 monitors for eyefinity, an overclocked i7 6-core cpu, 16gb of ram, have like 4 3.5" HDDs and 2 2.5" SSDs. Will the AX850 psu be sufficient for all those things or will I need a stronger psu? The question I'm really asking is, up to which point will I need more than 850w of power?

    An AX850 doesn't even come close to having enough capacity to handle four Radeon HD 7970 in 4-way CrossFireX mode. Even the AX1200 isn't enough but it will handle three Radeon HD 7970 in 3-way CrossFireX mode.

    The AX850 has the +12 Volt continuous current rating and four PCI Express supplementary power connectors to only handle up to two Radeon HD 7970 in 2-way CrossFireX mode.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817182239 -- Cool, Gold as well.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817159123 -- 1200 W, Gold for about same price and more W -- 200W more.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16817814019 -- 1100 W, Gold
  9. You don't want anything from Coolmax, or ABS.

    will the AX850 be able to handle 2 7970s in crossfire along with the other things that I mentioned?

    Yes it will handle all of the components you've listed and the overclocking of the CPU.

    The Corsair Professional Series Gold AX850 (CMPSU-850AX) uses incredibly overspec'ed components. You can draw over 1,000 Watts (1,045 Watts) from that power supply before it'll shut down.
