Graphicscard faulty?

[FreshKD21]

Hey, i just bought myself a new RX Vega 56, it has been running quite good the past few days but recently i played some more demanding games, after a few minutes my PC would crash. At first i thought it might have been a problem with my ram xmp (i upgraded ram at the same time) but it wasnt the problem. Now ive been experimenting with AMD Wattman and tried lowering the power limit, ive gone down as low as -50% because it kept crashing with -25% and or anything but -50%. I had a R9 280X before and didnt have the same problems, my specs are i5 6600K (stock), Corsair VS550 (the yellow/orange one not the silver one), 2x8GB & 2x4GB Vengeance LPX, Asus Vega 56 Arez/Strix, MSI Z270 Tomahawk. I hope any of you can help me and thanks in advance!

It has 550w right? Where is the problem, the Vega doesnt draw more than 230W on Stock settings

The problem is that Vega is known for very demanding transient power draw, and if you stress the GPU, it's going to pull way too much for that power supply to put out at once. It takes a decent PSU like a Corsair TXM to reliably handle Vega. Sure the VS can handle a few hundred watts sustained load, but the rails can easily overload.

So is it just a Vega thing? Because i overclocked the hell out of my R9 280X and this never happened, i easily went above 300W with that

like is said, it's the transient power draw and not the sustained. It is a Vega specific problems I'm 95% sure it's cause to get a new PSU. You can test some more by lowering the voltage of the card and not just the power draw.

Well i think its time for a new PSU then (wanted to OC my Vega and if this happens at stock i can say goodbye to any OC). Do you have any recommendations that are cheap and enough for a Vega OC?

What's your budget? If you're fine with non modular, the Bitfenix Formula Gold is a really solid unit.

My budget would probably as low as it gets (maximum would be 90€ but it has to be really good then), i would like to have a modular one because i hate having all those molex cables in my way ^^. How much more do modular PSUs cost? I would be fine with a no name PSU as long as it does its job

The cheapest sensible option is a Corsair CXM, semi modular. The aforementioned TXM is plenty good as well. The EVGA G1 and G2 are up for the task if you can get one for a reasonable price. The G3 has lesser protections so it's not recommended.

Could you tell me what to look for in PSUs? Because i just look at the CXM and TXM and tell myself 'why should i pay 10€ more just to have an T instead of an C because they literally look the same (atleast for me)

The quick and dirty is to check the PSU tier list the PSU guys have already gone through and checked quality on. The main apsects you're after are component quality, protections, fan quality, and features, but you'll find almost all of these exclusively in comprehensive PSU reviews and it's a lot of research.
