My motherboard is a 20-pin, but the main power cable on my new power supply is a 22-pin. It fits just fine but it has a set of pins hanging off the side. Will it start up if i try to boot like that? Should I send it back? Can I use one of those 20-to-24 pin adapters?

u mean ur PSU has a 24-pin connector?

anyways, if it goes in, its correct, u should be able to break off the last 4 pins

i hope you wrap the broke connectors in duck tape or something. that will prevent your board or computer from frying. Personally i wouldnt mess with it. Ive got a 24 pin MB and it will work witht the 20 pin connector anyways.

If it doesnt work, then get a 24 pin PSU. What brand is your 22 pin PSU? Ive never heard of a 22 pin PSU.

when i said "it should break off" i mean its supposed to come off, clips on and u can clip it off.

Read the post a bit closer, you got it backwards :lol:

You can plug it in and it will work fine, just as long as there is nothing the last 4 pins touch. I've seen a few 24pin ps's that DON'T seperate.

What do I lose if i do use a 24pin mb with a 20pin psu?
something like a a8r32-mvp with a single x1600 xt and thermaltake purepower 420W?

there was a big debate. the extra 4 pins powered up the PCI-e slots

As long as you use the 4 pin p4 connector it won't make a difference. I've seen 1900xt's run off 350watt p4 compatible ps's with 20pin main connectors.
