Which PSU/What wattage should I get?

So my current PSU is just a cheap, generic one, don't get me wrong, it works well, never had any issues, despite the experiences of some. I doubt it actually supports 850W, which is why I'd like opinions on a new PSU, for when I SLI 760's.

Current build is;

PSU - 850w cheap generic PSU, bought over 2 years ago.

CPU - i5-3570k @ 3.80 (stock cooler)

Motherboard - Z68AP-D3 Rev 2

Memory - 8GB DDR3 1600 (Will buy 4GB next week)

HDD - 1 TB 7200Rpm 3.5" and 500GB 5400rpm 3.5"

Video Card - 1 KFA2 EX OC 760 overclocked on top of factory OC, 100 additional core clock and 300 additional memory. (Will add another 760 in 1-2 months/SLI)

  1. Well if you sli 2 gtx 760s you will need at least 750W psu. the corsair Ax and HX series psu are good. All seasonics are also good.

    This website should give you examples of good psus and their current prices

    Also why are you using a 1tb 7200 rpm HDD with a 500gb 5400 RPM HDD. Why not use a 128gb SSD instead like a samsung 840 evo?

  2. 750W PSU will be sufficient for 2×760. This is what you should get
    XFX ProSeries 750W 80+ Gold @ $87.99
    http://pcpartpicker.com/part/xfx-power-supply-p1750bbefx
    It is Seasonic made, gold certified and modular
  3. ^ tldr Get the XFX gold maktovic and myself linked.
  4. Tea Urchin, Thats not true. How will you prove your point?

    Even if the XFX Pro and Rosewill Capstone share same Tier 2 Class A, but better build quality goes to XFX

    Just like HX and GS PSU from Corsair share same tier but we all know that HX series is much better than GS series in terms of quality
  5. That is an excellent psu. It is made by seasonic. Corsair, XFX, Seasonic are 3 of the very best and commonly used in high end rigs.
  6. Hey, thanks for the replies and thanks to the mod for moving my thread to the right section.

    Currently leaning towards XFX CORE EDITION PRO750W ATX12V 80 PLUS BRONZE, I couldn't find the Rosewill on any UK retailers to compare.

    So will that XFX be good enough for SLI 760, both overclocked and if I overclock my CPU in future and add 8GB more ram, will the PSU still be OK? Is it quiet?

    Oh, and does the PSU have all the needed connector wires needed?
  7. Great choice.It will power all your needs without breaking a sweat and the PSU's tend to get little louder at load but that won't bother you much.

    That PSU has sufficient wires ( 4× PCIe cable, 8 SATA connectors, 7× 4pin Molex connectors), you'll never run out of SATA & Peripheral connectors.

    No problem :)

    And you'll have no problem with GTX 760 SLI
