Default Home made Molex-to-PCI-E adapter?
How can I make my own PCI-E adapter? My GFX card needs a 6 pin, and currently my PSU is on RMA, and I'm using a generic 250watt and it doesn't have a 6 pin connector, and I don't have an adapter.

How can I make my own? Thanks.

You don't.

That generic 250w PSU is probably an old design without the current emphasis on the +12v. How many amps are on the +12v? You want at least 14A.

Also, you probably don't want to push 8-9A at +12v on single wire that is probably higher gauge than current standards.

Personally, if you must use your system... use only 1 RAM DIMM and underclock your CPU for now....

I wouldn't risk it, even if you made a custom homemade adapter.It shouldn't be that hard to make one thou , you just need 2 molex male connectors and 1 6slot pci connector and 6 wires... Getting the female pci connector is a bit of a problem...

14A on the +12v. CPU is at 1.6GHz, 1.2vcore, and I have my RAM at stock.

Is that 14A peak or constant? How unit so old that the capacitors have started to degraded or from the generation of bad caps?

Don't risk it.... reduce power draw as best as you can and wait for your replacement to come.. Otherwise, you risk RMAing more than just the PSU.
