I decided to build my own PC last December but I may have cheaped out on the PSU and I think I need to replace it before something bad happens. Currently I have a Powercool 750W which seems to work fine except the LEDs on the PC case keep flickering and it looks like some of the plastic covering the wires have melted inside.
Maybe I'm overreacting but I figure better safe than sorry, so I'd appreciate it if anyone could recommend me a reliable PSU. My PC has a I5-3570K, GeForce GTX670, Asus P8Z77 LK mobo, 8GB Corsair Vengeance and a 500GB western digital hard drive. I think 750W is enough for that.
If I do replace my PSU is it as simple as taking out the old one and putting the new one in? Or would I have to re-install my OS or something?
