PSU mounting

[hopkiller]

ok so i just put in my crosier 750w power supply in my case i mounted it upside down because its on the bottom and the fan was on the bottom of the psu. I only had to use three screws is that ok or should i mount it right side up.

Looks like there is no intake for the psu at the bottom in antec 900 so yeah put it like you want.

I believe they go in upside down in most cases with the PSU at the bottom. You can't flip it over because you need the fan exposed. Three screws is plenty, leave it alone.
