Really? 1000w isn't enough? GPU+cpu combined shouldn't use more than 450 at full load, so I should have plenty of room for transient spikes.
If I really don't have enough now how much is enough?
Is it the 7900 xt or the 9070 xt? 7900 xt does have a beefy power draw. But AMD's "Minimum PSU Recommendation" is 750W so 1000 should be plenty.
And the 9070 xt uses less than that.
9070xt for sure. Only has 16gb vram
Yes, your combined wattage use at peak is up to 1250, so you need to downclock, or buy a powerhouse PSU.
Your error literally says devices dropped offline. How would you imagine that happens aside from power drops?
That's definitely not the wording in the error, so I didn't realize that's what it meant. Is there anywhere you'd recommend I read up on mc5 errors?
Mc5 hardware error
Dafuq you think that is, son?
*Edit: post logs, ya baby ass bitch
why the fuck would i ask if i already knew?
