Hi all,
I've recently had a new computer build with a 8800GT as my graphics card, which uses 2 pci-e cables from the PSU, only, because my psu only has one, ive had to use a 2 molex to PCI-e adapter, and I think it is this adapter that is causing my computer to completly freeze.

Ive been having a look at adapters and have found this one :

As you can clearly see, this adapter has 6 pins. however, the one I am using on my 8800 only has 5 pins... Is there an explination for this? Am I using an older adapter and therefore only has 5 pins or is this picture i found on the net incorrect...

Thanks

I have two of the adapters and both have six pins, but only five are wired. The middle one furtherest from latch is empty. One of the adapters came with the PSU to allow SLI, so I don't think it should be a problem (I'll also be needing it soon). You'll get a warning if the card is underpowered.

The fact alone that your power supply has only one connector for your video card suggest it is underpowered and causing problems

I have a 500W PSU which is more than enough for a 8800GT

Off chance those molex connectors be pulling off of the same rail as the CPU/motherboard. You shouldn't be, but you never know. Most PSUs split up the 20/24pin and the 4/8 pin motherboard connectors to different rails. You might be locally overloading one rail. If it is a single rail PSU, then I don't know.
