I'm trying to find a replacement for a Bestec ATX 250-12Z Rev D2 for an old HP pavillion.
I've got a radeon 3850 that needs more power than the default PSU is providing, (12v 14A, 5V 25A, 3.3V 18A), I need a bare minimum of 20A on my 12v rail, probably 24 or 30 to be safe. The problem is, I have never replaced a PSU before and I have no clue how to go about matching it to my case to make sure it fits, and is compatible.
Can anyone point me in the right direction?

Look at the back of the case and see if there's sheet metal surrounding the power plug. Most aftermarket power supplies have the plug located a little differently than most HP power supplies.

Thank you for the fast response!
It seems to be about a quarter of an inch of clearance between the PSU plug and the top/left part of the back plate. I'm no stranger to case modding and I'll snip it out by hand if I really have to. HP seems has a thing for having to use the jaws of life to take their cases apart.

This is the back of the case, if it helps in figuring it out

Measure the size of the new PSU.
Make sure it fits. Or compare to the standard ATX size.
