Question about PSU sizes

[khchehab]

Hello, I want to buy a PSU but I'm afraid of getting any without regards to size. Are the PSU sizes standrad or should I measure the space I have on my case? In the case's page it doesn't say what size the PSU should be. The case I'm using is Thermaltake Chaser A41. The PSU I am thinking of in case it fits is XFX Pro 750W. Will it fit if I bought it?
Thanks for your help.

YES the PSU will fit and it's a great choice.

Most PC power supplies these days comply with ATX standards - see http://en.wikipedia.org/wiki/ATX

This includes the physical sizes of power supplies -"ATX power supplies generally have the dimensions of 150 × 86 × 140 mm (5.9 × 3.4 × 5.5 in)[12]:23–24 and share a common mounting layout of four screws arranged on the back side of the unit. That last dimension, the 140 mm depth, is frequently varied, with depths of 160, 180, 200 and 230 mm used to accommodate higher power or modular connectors."
