Question Under 100% load, will a 450w PSU be able to hold up against an rx 580?

I also recommend a 500 watt at minimum. You want plenty of overhead, in case you plan to overclock or upgrade your PC in the near future. Plus, more overhead allows the PSU to preform much better, and won't overload the unit.

Also, if you are on a budget, go with the CX550 series from Corsair, or the TXm units if you have a little bit more spending money. The BR units from EVGA are very basic and not that great in general.
