4870 Tri-Fire, PSU questions

[adairusmc]

I am getting ready to dump the 9800GX2 and go with a 4870 Tri-Fire setup, and I had some questions about my power supply.

Right now I have a PC Power & Cooling silencer 750. The rest of the specs are -

P5Q deluxe motherboard
Q9550
4x 2gb sticks OCZ reaper X
3 hard disks
2 optical drives
X-Fi elite pro
Dell 3007wfp

I highly doubt that my PSU will handle the 4870x2 AND the 4870, but would one of these work well? -

I only ask because I really dont want to spend a huge amount of money more on a new PSU, the 1kw and above PC P&C setups are a bit spendy (and I dont want undo my wiring and change that part out).

The two cards I am planning on getting are these -

4870 - http://www.newegg.com/Product/...x?Item=N82E16814102801


Thanks

yea that should probably work okay w/o having to upgrade your PSU in the process. they also sell a 650Watt version that takes up twice the bay space, but you probably dont need that much extra power. just run the HD4870x2 off the TT unit and the rest of the system off the PC Power unit and you should be good to go

That thing is Kick Ass!

My 4.0GHz Core 2 Duo + 4870 X2 only hits 350w in Crysis.
I really don't think having C2Q + one more 4870 would cause more than double (750w) in power consumption.

I went ahead and sprung for the VGA power supply to go with the cards. I just have a ton of fans, a few hard disks, couple optical drives, and a sound card that requires an internal power connector, so I figured I might as well be safe and not cut it close.

Cards and PSU installed.

Thanks for the replies. The machine is running awesome now (not that it didn't before with the 9800GX2 though).
