So i tried building my own pc and im pretty sure its my power supply thats broken but could they still check it out and build it for me and or help me?

In house its Geek Squad but for that money you could almost buy a new one. Good luck

No I don't

Geek squad will charge you far too much and most of their help is sending out and not done on site. Go to a small local shop or go online and order another power supply. Do you have a power tester a meter. They're real cheap
