Q: I have a pc with a r7 250 gb OC gpu + a 300W supply would putting this PSU in my case help the performance of my PC at all ? Its running a xeon quad core cpu and 8gb ram ty (and a DQ57TM intel mobo) rsvp thanks

The graphics card doesn't require a 6-pin power connector so this power supply should be fine, I doubt you'd see any real difference in performance just from replacing the power supply though. -Danlevan

Thought it would of been a good idea to go for a cheap power supply. Didnt fit on the motherboard and didnt have a cpu cable. Too old dont buy
