Hello Im going to get my first pc, from best buy. these are the specs:


*Ryzen 5 1400
*8gb ddr4 2133mhz
*Rx 580 4gb
*evga 450w bronze
*1T hdd

But I was wondering if I need to replace the psu in case that I added some stuff like:

*another stick of ram 8gb
*a ssd 120gb
*another 1T hdd
*x4 chasis fans
*cooler master liquid lite 120

can you tell me please.
Do I need another psu like 600w?

Im sorry for my bad english
 
Solution
Yes, I would. The PSU is undersize for the RX 580. 600W would be good. It would allow for some headroom. But most RX-580 cards will run nicely on a good quality 550W. Be sure to get a good PSU, no junk.
