No way will you run it on a 350w psu. Its actually really easy to use 2 power supplies, it just looks BAD. I would recommend to just get a new one thats around 500-600w. Dont get a really cheap $20 one either. The only reason I have a 1kw psu is because it was on sale for around the same price as a 750.Alright, I'll try rigging up an adapter for my 500W PSU (80$ Modular power supply ). Thanks for all your help.Somewhat true. A crappy low amp 600w psu wont be able to power a gpu with a lower power requirement like 500w. But still, a 350w with tons of amps still wont be able to power a gpu with a power requirement of like 500w. Anyways 350w psus dont have many amps to begin with. The only ones with 20 amps are around $150 anyways. You could buy a 1000w for the same priceQuote from: broque on September 15, 2009, 06:00:14 PM

It's not the volts (watts) It's the amps

And why do you need to rig up an adapter...

Sadly, my local computer store doesn't have any adapters, and buying from Newegg will result in a shipping cost exceeding the cost of the actual part.

I read here that you can just plug in a 20pin connector into a 24pin motherboard and it should work as long as you don't pull too much wattage from the motherboard. Any opinions on that? I'm considering doing that since I don't feel like spending 10 dollars on an adapter, and I can't find any female Molex connectors to make an adapter with.
