A Question about COOLMAX PSUs

[Bullet4Justice]

Hello guys, my GTX 970 GIGABYTE G1 just arrived to my country today from amazon and i'm going to pick it up later today, but i have a COOLMAX RM-850B 850W and it has enough wattage because the GPU only needs 550 Watts according to this:

but the problem is i saw this PSUs tier list on tom's hardware and according to it its very dangerous to run my GPU on it because its on tier five, take a look:

P.S: I have posted this before but people gave a lot of different answers so i'm confused, some people said that i have more wattage than i need so i'm fine, but some others said like what the tier list said that i should change it immediately

I wouldn't trust a Coolmax PSU around anything i just spent a couple hundred dollars on. You'll have plenty of wattage, but that thing could die at any time, and it's possible it will overvolt everything else in your system which won't end well.

 

EDIT: I would suggest taking a look at EVGA's 750G2 or something from Seasonic/Corsair.

I wouldn't trust a Coolmax PSU on much tbh, perhaps my kettle

 

You'll want to replace that ASAP/before you get your new GPU
