Will older Motherboards work with newer PSU's?

Most older boards use a 20 pin power plug.
Most new PSU's have a 20+4 configuration,
so you can use them on older boards as well.
BUT, if your PSU has a 24 pin power plug, I
don't think it will work. It might, but personally idk.

Not too many PSU's have straight 24 pin plugs. If it did, and the older board only accepted 20 pin, you'd have to do some modifications. The pin-out and all should be the same, but it probably wouldn't fit due to those extra pins and all
Remove them or something and you'd be fine

unless its a really old mobo that the psu had a fixed on-off switch, you should be fine.

what do mean by fixed on/off switch?
A 24 pin power connector will still fit a 20 pin board. just make sure it has enough room to one side to overlap. They are both wired the same other then the extra 4 pins.

That's what I wasn't sure about, if you could just hang the extra pins off. :good:
It will work. But some boards will have a capacitor or another connector all bunched up beside it where it wont have room.
