Will the PSU handle it?

Hi guys, so I have an XFX 750W XXX 80+ Silver, and I know it's a quality unit, but I was wondering if I would be pushing it by trying to power the following:

- i5 2500K @ 5GHz w 1.42v
- 2x GTX660's in SLI (overclocked)
- GTX460 (stock clocks & undervolted)
- 2x 7200RPM SATA drives
- 5900RPM green SATA drive
- SSD
- 4x DDR3 modules
- XSPC 750 pump
- 3x 140MM LED fans
- 120MM fan
- Sound card
- LED lighting

The system will spend a fair amount of its time at 100% load on all three GPU's and the CPU (folding)

If it's too much I will just leave out the 460. Cheers guys

Your PSU Probably won't break a sweat!

Good to know RJC

That's what my gut told me, but the PSU calculator recomends at least 755W for peak load.

But we both know that PSU will perform way past that

Most likely true, and the system won't be 'peak loaded' even when folding on the GPU's + CPU, but I don't want to fry my new PSU haha.

Anyway, if you're alive, Y U NO BE SOCIAL?

No probs

Just tried Extreme PSU calculator and this showed recommended PSU wattage as 685w.

Ah OK, never mind then

It'll be fine. My system draws 580W on full load so I can't see yours being >150W more?

IIRC when it first came out reviewers were able to pull 900w out of it.

Remove the LED lighting and you'll be fine

430w at the wall for the spec in sig when gaming, that also includes the monitor. Other bits not in sig are an ssd and a 1tb hdd, xonar dx audio card along with 9x 120mm fans.
