People that use "value PSU's" usually end up with fried systems.

 

I used a super flower platinum 1200W, highly praised psu until last week and apparently ended up with a fried GPU...

 

What GPU? Check if it's got fuses on it. Look like resistors but are white, usually next to the power plugs. If you're lucky, you might just need to replace the fuse/fuses and your GPU will be good as new.

Antec Neo Eco 1300 is a Tier B psu that will very likely cause tripping issues with high transient power draw, I probably wouldn't plug a 3090 into one of those.

Take a look at that list and note the footnotes next to the PSU's you might be considering.

Thank u! I'll have a look at the Cooler Master MWE 1250W gold as well, also Tier B on that list but far more information/test results available on it...
The Antec neoeco 1300 gold is a 100A+ single rail design, that gives some chance against the transients I guess.

I've had a friend with the Antec Neo Eco 850W. It didn't have any issues but it wasn't very quiet as well.

 

very impressive psu
