Question Well...that was pretty painless...

[BoomerD]

Ordered a new EVGA RTX 3070 video card. Requires a minimum of 750 watt PSU. The one in my pre-built IBuyPower PC was 650 watts (CWT GPS650S) non-modular.
Replaced it with a Seasonic SSR-750FX fully modular PSU. Not only was the install easy-peasy, I was able to eliminate a ton of extra unused cables. (floppy, molex, and a bunch of SATA power cables that weren't needed.
I did have to partly uninstall the radiator/fans for my AIO CPU cooler to get to the 4+4 pin connector on the motherboard...but that was only 2 screws.

Now...what to do, what to do with this old PSU?

Take it up high somewhere and drop it like a myth buster!

Or stash it in a box somewhere just in case.

It's not one of the best PSU's made...but it never gave me any problems. For now, I've boxed it up and stuck it in the garage with my other surplus PC junk.

Always keep a known working unit like PSU on hand for diagnostics in the future if you have problems.
