I have a PCP&C 1k psu. This might sound like a stupid question but would anyone be able to tell me if I am getting closer to the limit of this psu? I have 6 500gb western digital hdds, 2 7950gx2 video cards(sli), an evga 680i t1 revision board, qx6700 multi x11, ageia physx card, pci x1 esata card, pci-e x8 esata card, 10 120mm fans, 1 80mm fan, 2 ide dvd-dl drives, i card reader, AC Freezer 7 Pro, 4 sticks of memory each 2gb from ocz 667mhz,

I hope thats enough to narrow the answer down.
 
I'd be curious what case you have all of that piled into - that rig sounds like a prime candidate for a secondary PSU or offload of your storage drive array to an external eSATA enclosure. The size footprint of the fans alone makes me think you're running inside of a mini-fridge size enclosure... *10 x 120mm fans?!?

Pushing 800 watts at peak is still well within that PSU's limits though I imagine it sounds like an unholy tornado when you start gaming and the cooling fans in PSU and video card cooler spins up to full speed.

I was curious, so I plugged your info into this PSU calculator. You're using around 800 watts. If you OC'd the qx6700 it's higher.

I doubt that machine even draws 600W from the wall.

OP: You've got enough money for all of those parts, go out and spend $30 on a Kill-A-Watt and see what you're actually pulling from the wall. I bet you'd be surprised.

The only way you'd actually need > 800W is if you had a CoolIT in there cooling your CPU, GPU's or both or if you had a water loop with two pumps or some other kind of TEC cooling.
 
Thanks for all your replies. Yeah it is a monster case its the thermaltake mozart case. And yes it sounds like a jet plane but thats ok I don't keep it on all day. Just to make sure here I plan on getting 2 8950GX2 cards so would I need to go to the thermaltake 1200w psu? Or would mine be able to handle it.

Also on a side note If a bios update is all thats required for my board to run penryn Ill be getting a quad of that if not I am getting an thermalrite ultra-120 extreme and going to oc my current quad more. Will my psu also be enough for this or will I need a greater output one?

I can't imagine your electric bills if you kept it on all day lol. Nice system though.
