Hey Paddy,

I dont want to cross post but wanted to ask a quick question someone with 8800GTX cards. I noticed that the card is got 2 PCIe power connectors. Does each card in your system requers 2 PCIe power cables?

No worries ...
The answer is ... yes ... hence my 2 PSU's ... see my specs below ...

Thanks Paddy. I have first release of the P&C 1KW PSU so it only comes with 2 PCIe cables. They got a new version with 4 now. I guess i'll have to upgrade when i'm ready to get 8800s.

That's a pain ...

Another thing worth mentioning ...
I found just one of my 8800GTX's is faster or about the same on most games than the 2x7950's I did have ... :shock:
At the moment having the second 8800 only makes for a small increase in FPS over one ... hopefully they will improve this with better drivers.

found just one of my 8800GTX's is faster or about the same on most games than the 2x7950's I did have .

The benches of quad SLI i saw did show only partially more performance even in high resolutions...

no way they will run the last level without turning everything down or even lowering the res to 3072x768 ... sorry guys.

I hope that if I deal with that level a 8800gtx will be mine....

Thanks for the heads up Paddy. I'll have to get 2 either way other wise my water system wont balance right.

How do you fit 2 psu's in your case?

It's a big case that Silverstone TJ07B ... :wink:



View the case ... @ scan ... mine is black not grey as in this link ... http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=326330

Did you test your system once with only one tagan ps ?

No ... each 8800 requires 2 PCIe power cables as mentioned earlier.
When I first got the system (nearly a year a go) I had 2 x 7950's they also required 2 PCIe power cables each ... don't think there was a PS that had 4 PCIe power cables back then.

Hi Paddy,

The only question I want ask is how much do your house lights dim when you crank up all the gear you have? (or did you buy a generator along with the 8800's? :lol:

:mrgreen:

Can't you just use a pci-e splitter to power the four connectors off two pci-e lines?

A minimum of a 450W power supply is recomended for each 8800GTX ... I'm not going to risk it ...

A 450W PSU is recommended for one whole system which has one 8800GTX. The card alone doesn't need a whole 450W.

I don't know if there are any better alternatives to getting 2 PSUs though. Aren't there some PSUs which like 800+ W and 4 PCIe plugs which would work?

Yes ... there are now ... see RUS007's second post above ... and as I said I don't think there was when I got the system.

Nice one Paddy,

That’s a good thread to have on its own.

My 1KW PSU only has 2 PCIe cables only because there wasn’t need for 4 when it came out. I could technically use my PSU for 2 8800s but it would be nice to stay away from splitter cables to keep the system nice and clean.

Can't you just use a pci-e splitter to power the four connectors off two pci-e lines?

Yes you can if you good a strong 5 1/4 connector!
