Is my PSU capable?

My current system specs are,

Cooler Master Haf-X
Corsair HX750w
Asus p8p67 Pro
i5 2500k OCed to ~4.8
Noctua NH-D14
EVGA 9800 GTX+
3 HDDs
G.Skill 2x4Gbs DDR3 1600
1 Optical drive

So it's time to upgrade the graphics card and I've scrapped together enough and I'm thinking about picking up 2 GTX 460 1Gbs right now because I'm confident my PSU can handle both of those. However if it's able to, I would prefer to either get a 560ti or maybe even a GTX 570 now and pick up a second around Christmas. Honestly I would prefer to not be cutting it super close and not really have any headroom so I'm content with the 2 460s if it would be too close on either of those later 2.

Thanks in advance.

    The HX 750 has plenty of power, it would have no problem running 2 GTX 570s with some overclocking, as long as you arent planning on a pair of GTX 580s, 5970s, or GTX 295s that you want to OC you have plenty of power.
  2. I wouldn't feel comfortable putting two 570s together with just a 750w PSU. If I could give a suggestion, buy a 560, and use your GTX+ as a physx processor. It would give a meaty increase in framerates without needing to SLI anything.

  4. 750 watter is cool for SLI's 560's ....nVidia has certified numerous 650 watters for even twin 460's. With 570's and CPU / GFX overclocking, most would consider a 750 is a bit tight .... I'd want more headroom so as to main stable voltages (within 1% variation) under high OC's.

    The following units get 10.0 ratings from jonnyguru.com

    Antec SG-850 - $250
    Antec CP-850 - $120
    Corsair HX850 - $150 after $15 MIR
    XFX Black Edition 850 - $130 after $20 MIR

    I have used them all ..... of late though, only using the CP and the Blacks for obvious reasons.
