I recently bought a power supply that has a fan on the bottom and I was hoping it would draw air from the cpu area of my case. I found out that instead of drawing air out of the case, the fan rather blows air into it. The PS is a 254w Dynapower model #MAU-250P1.

Thanks in advance :)

what kind of case do you have?

moreover, you power supply should blow air OUT OF THE CASE, so i dont know what kind of weird thing you got..........

Sparkle Power also makes a couple power supplies that sucks the air into the case. So you could consider your power supply normal, but yeah, there are few like them.

Blowing into the case was the intended way in the first ATX specification. Blowing this way the CPU should be cooled only passively. But with the new CPUs that surely can't survive without active cooling (except mine with the giant Alpha and in normal win/internet use), the PS Fans got back to normal operation.
So you have something special ;)

I'd try to change poles or remount the fan blowing in the other direction (if possible and if it blows out of the back end then...)
Otherwise your PS might get overblowed, he, he, he...

enjoy
