Sig rig + 1 8800GTX for Physx on 750w?

post #1 of 4
Thread Starter 
Ive been on various sites using the calculators. I bought an 8800GTX off a member here and it will be used as a physx card.

The 750TX enough for my sig rig plus the additional card? CPU is stock clocks. GPUs are mild OC'd.

Im thinking its far to close and will probably install the 8800GTX into another PC...or go with a 1kw PSU.

An i7 970 with a pair of stock 6870s generate a total system power usage of some 449W, max under Furmark.
So, even given yours are slightly oc'ed, I think adding an 8800GTX as Physx card should be still OK. However, your 750TX has only four 6(+2) PCIe connectors which should have already been used up for your pair of 6870s. And since an 8800GTX needs two such connectors, you will have to use ''4-pin molex to 6-pin pcie'' adaptors.

As a side suggestion, get yourself a Kill-A-Watt power meter or equivalent. It is a useful tool to keep for the long term. If you got one already, use it to test the current max power usage and you will be able to get an accurate picture of how much reserve you still have from your 750W PSU.

You'll have MORE than plenty enough wattage for your sig rig + an 8800.
