Running a PSU upside down?

z0mbi3 · 12 Feb 2008 at 11:59

I don't have much clearance at the back of my case and my PSU appears to be getting hot and ramping the fan up because of it. Moving the case isn't really an option so I was thinking about mounting it upside down and cutting a hole in the top of my case for an intake.

I figure that if I have cool(er) air from outside the case just being circulated by just the PSU then it will generally stay cool enough to stop the fan from ramping up. I have suitable cooling for the rest of my PC, so I only need to worry about the PSU as far as this thread is concerned.

Any thoughts?

Shouldn't matter in the least, PSUs can work in any orientation you care to put them in. The only point to note however is that some PSUs vent hot air from your case which could mean that the internal temperature rises, keep an eye on this.

All its change will fall out of its pockets!

The Antec 900 has the PSU at the bottom, and so is upside down. Works fine.

OK so we're all happy that upside down isn't a problem. Is every one agreed that so long as I have a good exhaust for the case that having the PSUs intake come from a hole in the top can only be a good thing?

should work well.
i can only think of 1 psu that doesnt like being run upside down, and thats the koolance watercooled one. but that has its fan fully outsid the case anyway
