Replacing prebuilt PSU : proprietary?

[Cifer]

Hi,

I have a prebuilt that uses a delta PSU (GPS-300JB A), and would like to replace it with a brand new PSU.
I couldn't find much info about this unit, other than "ATX 12V" under "Form Factor" :

A few pics of the motherboard 24pin and CPU 4pin :

 

Can I just assume that the motherboard pinout is regular ATX stuff, or should I first check with a DMM ?

ATX is generally ATX and the CPU 4+4 should be standardized as well. However, dimensions (fit to the case) are what can really trip you up here, and no, from that standpoint, they are not all the same. You need to measure your existing one, most are measured in inches or mm. LxWxH, L may be referred to as D (depth).

Looks like regular ATX connections.
Googling the PSU gives a normal sized square box, so replacing it might be as easy as pick what you want and fits.
