PSU Question

Hi guys I have a small question. I have a Coolermaster Real Power M700 PSU.
What I would like to know is if you guys think it will be powerful enough to power both my new GTX 295 and my old 8800 GTS 320 off a molex to PCI-E adapter. I would like to dedicate it to physics.

My other components are:
-P5k Premium Wifi AP
-Intel Core 2 Quad Q6600 running at 3.14 GHz on Zalman CNPS 9700 NT Cooler
-4GB of OCZ SLI Edition RAM
-Velociraptor HDD
-I also have a small IDE HDD
-SATA DVD-RW Drive
-Hiper Anubis Case with two extra Scythe Gentle Typhoon fans

Thanks for the help.

to be honest with u, not a chance,

to power the 2 GTX 295's u would look for roughly 1000w to be onthe safe side.

to power the extra card also, i would recommmend any quality branded 1200w PSU's.

I only have one GTX 295. But thanks for the reply.

Can't find your answer ? Ask !

The GTX295 pulls about 300w at load, the 8800GTS 320 pulls about 100w. Figuring 200w for the rest of your OC system i'd say that the 700w is going to be pushed at 90% of it's capacity at load. I'd personally invest in a different PSU, probably a 850w +

Corsair 850w $120 after rebate looks pretty good.

Thanks for the reply. So you believe it can power it even if it's pushing it a bit?
Thanks for the PSU recommendation. Unfortunately that one isn't modular and anyway I'm in the UK so everything costs a lot more here.
I don't need to run the second card anyway. I was just checking if it was feasible.

Power supply manufacturers recommend that you run their PSUs at about 60% of their rated capacity. If it were my system i'd leave the 8800GTS 320 out of it.
