Windows 7: Two PSU slots on this full tower?

Two PSU slots on this full tower?

I recently rebuilt my desktop inside a Cooler Master HAF 932 Advanced Edition full tower, and I noticed that it has two spots for a PSU: on the top and on the bottom. The instruction booklet also mentions installing a PSU in the top slot as optional. Does this mean you can have two PSUs in the same PC? Sorry if this is a dumb question, but I'm kind of new to building PCs on my own, although I got everything working 100% with the rebuild I did.

congrats on getting everything working with your recent build . you wouldn't usually install 2 psus as you'd have to come up with some fancy rewiring to make it work (as the big connector goes onto 1 motherboard directly from the PSU, as well as the motherboard connectors to operate the case buttons etc)

however, it is possible, if you are a crazy modder or trying to do something out of the ordinary...

I expect the case you have supplies 2 mounting locations to give freedom of choice, rather than expansion

My best guess would be that the reason it has two different spots to place the psu is to give you the choice of were ever you believe it would be better suited.

Place the PSU at the base of the case. Mine is at the top and I find it completely un-logical.

+1 for the base as it's weight down low is easier than up top when picking up and handling the case.

Yep, the base is where I put it. On this specific case, the base is easier to install it to. Otherwise, I would have had to remove a chassis fan to get to it easier. Plus, I like it on the bottom more anyway.

This case is amazing though, especially since I got it for $129, and its normally $179, plus I got free shipping (Newegg). Since its mostly steel, its heavy (almost 30 lbs for the case with nothing in it). It did come with wheels though, so I mounted the wheels on it, and now I can very easily slide my PC to move it when I need to. Also, I saw a MASSIVE decrease in hardware temps after getting this setup. My Core i7 920 is running at 22 C on air cooling.

My PSU is in the bottom of my HAF.
The wheels make it really nice.

You can install two PSU's. That would be unusual but they will fit less one top fan.

Hope you enjoy the cool temps as much as I have the last 18 months with mine.
