my motherboard is a

P5VD2 MX-SE model, and im not sure what psu is compatible with it. i tried googling but it doesn't explain psu compability, only cpus....

my current psu is a Sunpex ATX 450ps, and i thought its a 450w one, but i read from some site that its only a 250w psu.

im currently using the 250w to run a radeon hd 4670 video card, and i experienced no issues with it.

Can experienced onrpgers provide me with some insight on picking out a psu thats compatible with my motherboard???

or is all psu compatible with any motherboard?
