Do I need a new PSU?

[edgard.rodrig]

Hi everyone, I recently got an RX 580 for my pc, and I'm now wondering if I need to upgrade my PSU. I have a Bronze+ Certified 450W EVGA power supply. It had no problem running my old 950ti but am now wondering if my pc would benefit from more power. Here are my specs:
Ryzen 1500x
8GB DDR4 Ram
Micro atx mobo
7200 RPM HDD
and the new RX 580 GPU.
Thanks for the help guys.

I would get a decent 550w for running a 580.

Ok, will look into it, my pc started having small hiccups lately too, like froze sometimes when it never did before. Do you think the PSU could be to blame or should I look to troubleshoot other things?

GTX 950 ti? There's no such thing. Either gtx 750ti or gtx 950.
Anyway recommended minimum for RX580 is 500W.

Depending on actual EVGA 450W model name it has either 420W or 448W on 12V rail. Non OC RX 580 model uses ~ 185W.
So about 250W is left for the rest of the system. I'd say - your current PSU should be able to handle it.

It's a low end EVGA PSU , I'd upgrade it.
