I have a 20+4pin main connector typePSU and a 24 pin ATX motherboard. Can I make them work together or do I need a new PSU?

Hello Dowdgretch,

If I remember correctly, if you have a 24 pin power connector on the motherboard you will need a 24 pin PSU. I am assuming when you say 20+4, the main connector is 20 pin and you have the second 4 pin connector for the part that is beside the CPU.

It can however work the other way around. If you had a 20 pin motherboard and a 24 pin PSU, you can still use the 24 pin PSU connector and leave the extra pins unplugged.

Yep-- you can adapt down to 20, but not up to 24.
The new board will draw more than the PSU could put out anyway.

Thank you very much ih8bills and Wadd for your prompt and helpful reply.I plan to use the powersupply calculator to figure out what I need.

Since you are US-based... once you figure out how much power you need--try Newegg the best service --in my opinion.
