Corsair GS600 w/ Xfired 6850's?

[pjl21]

I wanted to get some confirmation... the Corsair GS600 has 48 amps on the +12 volt rail.

Will this work with two HIS 6850s IceQ X Turbos in Xfire?
If not, will non-oc'd ones work?

Current system:
990FX Asrock am3+
Athlon II x4 @ 3.4 GHz
HIS IceQ X Turbo 6850
Cheap samsung ram 1066 mhz 2x2gb
GS600

They should work just fine. 600w is more than enough for dual 6850's in my opinion.

From another post, the required amperage decided was around 30-35 ... will the other 13-18 be enough for my system?

According to this review (very reputable source) A pair of 6850's in crossfire draw 245w. http://www.guru3d.com/article/radeon-hd-6850-6870-crossfirex-review/4 Your CPU will draw a max of 95w. let's say the HDD's DVD's and fans use another 50w, which is quite generous. you have a total of 390w. Now we need the amperage, right? assuming all of that stuff is drawing off the 12v rail (which it's NOT) you'd still only be drawing 32.5 amps from the 12v.

The 6850 is a very efficient card, drawing only around 12 amps at full load. You should have plenty of headroom. You can use this PSU calculator (regarded as the most accurate) to puzzle out the numbers yourself. http://extreme.outervision.com/psucalculatorlite.jsp

It would be enough. 48A on the +12V should handle the 6850 CF. I'm pretty sure max your power consumption of your whole system shouldn't go above 500W (with 6850 CF).

Alright, I figured that, but thanks for the confirmation!
