[USA-PA] [H] PayPal, Local Cash [W] low cost PSU 600-750w for gaming PC

Hello. I am currently upgrading my child’s PC. I bought him a bunch of new gear but his PSU can’t handle it. I need to keep costs very low since I just spent more than I have on this little turd 😂. Trying to keep it under $60. It does not need to be anything crazy. Please help!
