Drop whatever you're gonna fit in your pc in the dropdowns and go from there.
If you then grab a crapy cheap ass PSU, best to sit way above the minimum from that list.
Good 500 Watt PSU will outperform a crappy 800 Watt, So i tend to turn to really awesome PSUs
Also, in general, psu problems tend to get vague. Stuff works, but you get weird ass crashes or other shit that's hard to find out.
I always turn to A brand highest tier PSUs tbh. Atm , I have a seasonic X Gold

If it's usb stick, microsd, flash, ssd, or just a general HD, they have the best listed in their leaderboard. I always go there then check local pricing and grab something up that way. Idiotically fast micro sd of 128 gb for 50 bucks for instance
