What brand is your PS? Thats always a factor… If you have a good name brand PS you probably wont have a problem.
On the other hand, having PS issues can really fuck up your hardware. If it was patching up an old system until you get your new one I’d say go for it. But, I wouldn’t take a chance with a new machine, its not worth the potential damage.
That said, if you have a good PS you may get away w/ it, but I’d probably go for a new PS anyways.
New PS ftw.
