Hiya folks,

I'm currently shopping for a new CPU and a pair of video cards to extend the life of my rig for a couple of more years. The only thing I'm curious about is whether or not I should also get a new PSU to compensate for the new parts. First of all, here are the current specs of my rig:

PSU: CoolMax CUG-700B 700 Watts (older model, bought in Jan. 2007)
Motherboard: EVGA nForce 680i SLI
CPU: E6600 Conroe 2.4 Intel Core 2 Duo (OC'ed to 3.4)
RAM: 6 GB Corsair Dominator (tweaked to 378mhz for 1:1 ratio w/CPU)
OS: Windows 7 64-bit (of course!)
Video Card: 2 EVGA Akimbo Superclocked 8800GT

I'm planning to upgrade the CPU to E8400 Wolfdale 3.0 and the video cards to a pair of EVGA GTX 460 Superclocked (Fermi).

With the mods I've done to my computer, the current PSU works just fine with no problems. Now, do you think I should also bump up my PSU to handle the new parts as well as the mods I plan to do? (I figured 850W is plenty safe and allows for future builds). I'd much rather stay with the current PSU in the interest of saving money, though.

Thanks buds

Power wise, you should be fine with that PSU, however, hardware wise, no, that video card-if Im not mistaken takes 2 6 pin PCI express power cables per card. That Power supply only has 2 total, so you will either have to find more PCI express cables (its modular) adaptors from molex to PCI express or a different PSU.
