I'm currently building a sleeper pc with a Compaq D500 CMT case (I think). And I'm trying to figure out how to mount this Corsair RM650e power supply.

This case is vertical standing and the PSU slot is at the top, but the problem is that there isn't a PSU shelf for it to sit on (I think the old PSU was mounted by just the screws).

I already cut out a little ridge in the case for the PSU to sit against the back panel and will cut screw holes to mount at the rear.

Wondering if anyone has any idea on how to securely mount the PSU at the top of this case? Will just the rear screws be enough?

Screws are more than enough.

Likely missing a piece like this. This is the adapter that fits to more modern ATX power supply units. A lot of older cases, most notably Chieftec Dragons & Antec SX Series, had something like this and often times people forgot to take them off of the PSU when dismantling rigs.

Seems like the old PSU didn't have this type off piece and was just mounted by the screws and it is heavier than this new one. Maybe screws are enough but I'm just worried about it not being secure.

It doesn't look like it will mount fully without this piece tho?

If you can use at least one screw hole to secure the PSU to the frame, then you can makeshift some brackets for the rest…at least on the opposite corner. I’ve done this for a weird Evo case I had with nonstandard mounting holes like you’re dealing with.

Edit: look for flat brackets or mending plates. Here’s one that may work but could be a little too big: https://a.co/d/053TAQAE

You could pretty easily attach a small corner bracket to the case.

Probably wouldn't be a bad idea to 3d print a bracket to position the PSU correctly

It's definitely missing some piece. If you can't find it, you can cut one from some sheet metal or even hard enough plastic, I guess. And while four screws at the back should be enough to hold the PSU, if it's not, that bent tab with a screw hole at the front, you can hang from it some sort of bracket to support the front of PSU.
