Question Sapphire Nitro+ RX570 in 450w?

[alyna.jb1]

Hello currently I have

Cpu: Athlon 200ge (soon to be upgraded to Ryzen 3)
Ram: 8gb 2400mhz
Psu: P450B 80+ Bronze

My problem is in Sapphire website, the RX 570 need atleast 500w but some says it just need 450w? I just want to clarify.

The bequiet power calculator gives a power consumption around 250 W for these CPU and GPU.
So, yes à good 450w PSU would be ok

If you have a good 450w PSU, you should be fine, but if you are already going to be upgrading the PSU, id recommend something maybe more like a 550w, just to give some headroom
