Mounting a XFX 550w PSU in a Corsair 400r? (first build)

[BoroFiend]

Hello all! I just recieved my Corsair 400r and my XFX 550w PSU in the mail! I was wondering if anyone else was running this PSU and case and how they mounted the PSU. The case is built for bottom mounting, but I wanted to make sure that it would be alright if I mounted the PSU so that the fan is facing the bottom of the case, pulling in air from the bottom. I'm able to screw in 2 out of the 4 screws when I mount it with the fan side down, but it seems to be held in place very well with just the 2. Can anyone help me fig this out?

That is the preferred way to mount a bottom mount PSU. And all 4 screws should find their holes. PSUs are universal when it comes to mounting fan up or fan down. You're just not looking close enough. There are six holes or slots on the case. 4 of them line up with the holes in the PSU.

If you look close all 4 holes are present.
