PSU SIZES

Any ATX (anything that isn't marketed as SFX is ATX) PSU will fit in an H440.

 

The vast majority of cases (some small form factor and some pre-builts excluded) use the ATX form factor -- the only difference between ATX PSUs is the length. The length can be an issue in some cases (usually smaller ones), but the H440 can handle any length PSU.

There are, other form factors such as SFX, SFX-L, Flex, TFX, and a couple others, but you should buy an ATX PSU - one of the most common.  You could grab a SFX/SFX-L PSU; however, those are much more expensive and not needed in your case (so I'd avoid them).

Thanks for the reply. Now I am concerned about the power supply. If my build uses around 450W and I have installed a 600W power supply will it be a problem?

So where would the rest of the power go? Example - If the build utilizes 450W and PSU is 600W so that is 600-450=150W where did that power go?

Should I be concerned about the electric bill?

It simply doesnt draw it. 600w PSUs supply 600w DC power to the PC at most, but it can supply less if the PC draws less. A bit like a water tap.

 

What unit is that though? There are quite a lot of bad 600w PSUs out there.

Please suggest me a good PSU for me. Does NZXT Phantom 530 fit all ATX PSUs?
