Monitor turns black and windows disable my GPU driver

Undervolting is done in software e.g. Radeon Software or MSI Afterburner. Lots of guides on this here or youtube.

 

If you want to keep the system, then get a new PSU. I prefer to buy overkill PSU specs, as this will mean less stress on the unit, and lower heat. Also means the PSU will last longer. I have a Cooler Master Silent Pro Gold 1200 in my system that is from 2008(?) and still kicking butt.

 

What do you guys think about this PSU?

SEASONIC Powe Supply B12-BV 650 W - B12-BC-650

 

It depends on what price you can buy it. Overall it seems okay, but there are many more interesting units at this price in my country.

 

I can buy that or this one
SEASONIC Power Supply G12 650W - G12-GC-650

 

I find out there is one more Sea Sonic with this price range. SeaSonic CORE Gold GC-650 (SSR-650LC)
It has more sensors (SIP, UVP, AFC) and a longer warranty (7 years vs 5 years) and overall it has better quality.

But if you really only have a choice between those two, choose G12-GC-650

 

I have only choice between thoose two

 

Never scrimp on your PSU.

 

Am not trying to scrimp this is only two PSUs that have popular brand in it others are LC power and Ig max PSUs

 

got kind of the same issue on one of my retro rig, computer turn on just fine, as soon as i launch a game, black screen.
thought my x850xt had died of old age, bought another one on ebay, plugged it, fired a game, same deal :x
now waiting on a new PSU, hope it get the problem fixed

 

It's MPO issue. Disable MPO and you will be fine.

 

Read topic again, he's PSU made burned plastic smell its not always MPO

 

I didn't had any burn smell. My monitor just turns off and I had sometimes some weird noises with PSU when I boot up PC but after that everything was fine until I start to play some demanding games like RDR 2 etc. then my monitor just turns black and that's it I need to reboot my PC again

 

Hey guys, this is unfortunately my only option
They told me they can give me this PSU
What is your suggestion should I buy this one. This one have 750W my IG MAX had 600W. Probably doesn't matter but still tell me your opinion since this is only one option they gave me for PSU without losing warranty.

COOLER MASTER MWE 750 WHITE 230V MPE-7501-ACABW-EU V2 - Power Supply

 

I've had a good history with Cooler Master PSUs, and the 150W of extra power will do you good.
