Power supply. Downgrading 24pin to 20 pin??

February 1, 2010 at 00:16:27
Specs: windows 7, Athlon X4 620 2.6Ghz/ 6GB
I have an older computer motherboard that supports a 20pin power connection. The psu crapped out on this computer..
I needed a new psu for my current computer so I upgraded my current psu and I was going to swap the original psu to my older computer.

This psu power connection is 24 ( With no module for the last 4)
Can I physically cut the plastic for the last 4 and plug it in?

I actually did cut it and it plugs in completely fine, though I have not attempted to turn it on as worry it may fry the motherboard due to power outputs of the connection?

It will work as long as you've removed the 4 pins from the correct
end - the 4 extra pins provide an additional 12v rail, usually for
PCIe cards I believe. You can check for sure by comparing the
wiring colours which should be standard, You can also get 24pin
to 20pin adapters, if you want it to be tidy.

You probably didn't need to cut it but what's done is done.
