Need help with picking right PSU!!!

[Brada420]

3 years ago I was 7th class at school and I didn't know how to properly build a PC, so my parents IT guy picked some parts and sent that list to PC shop where they built it. Now 3 years later (with obivously more knowlage than before) I upgraded my graphics card from Nvidia GT730 to AMD RX 570 Oc (and yes, I checked on my PSU specs to be sure it could handle it) and I started experiencing random shutdowns on my PC and BIOS everytime sayd that 'Asus anti-surge protection triggered problem'. I assumed that PSU is problem, and I was right. I only checked specs of it, and I didn't check other people reviews for that PSU. 90% of comments are that that PSU is a bomb.Here is the link from it

Corsair cxm is solid choice

Corsair CX 2017 550W (actually better than the CXM because of its half bridge LLC topology vs the CXM's double forward)
