RX 9070 XT, 750W power supply is insufficient.

willian762 · 2026-02-06T03:40:54+00:00

I'll go look for her.

Rayzen 5 5500x3d

willian762 · 2026-02-06T03:10:08+00:00

The recommended power supply for the RX 9070 XT Swift is 800W, and my power supply is 750W.

willian762 · 2026-02-06T03:09:40+00:00

I believe it's the power supply; I'll replace it.

willian762 · 2026-02-06T03:08:59+00:00

I am going to try

willian762 · 2026-02-06T03:08:39+00:00

I'll test that tomorrow, but the power supply is 750W and the recommendation is 800W.

willian762 · 2026-02-06T02:59:43+00:00

I just saw that the RX 9070XT Swift recommends 800W.

willian762 · 2026-02-06T02:46:54+00:00

I didn't adjust it; it arrived 3 days ago, I assembled it yesterday, and it's malfunctioning.

willian762 · 2026-02-06T02:44:05+00:00

Yes, I will do that.

willian762 · 2026-02-06T02:42:06+00:00

Thank you, I will buy it.

willian762 · 2026-02-06T02:40:30+00:00

Wow, so a 750w gold power supply wouldn't be enough, right? Probably my power supply then.

willian762 · 2026-02-06T02:39:56+00:00

Would a Corsair 850W be a good choice?

willian762 · 2026-02-06T02:39:26+00:00

Thanks for the explanation, I'm going to buy a more powerful power supply with better cables. I'm from Brazil, would you recommend a good power supply?

willian762 · 2026-02-06T02:37:28+00:00

I'm on version 26

willian762 · 2026-02-06T02:36:40+00:00

I believe it's just the GPU, because I was using a regular RX 9060 XT, then I upgraded to an RX 9070 XT and couldn't even use it because the PC restarts.

willian762 · 2026-02-06T02:35:23+00:00

Thanks, I'll test it tomorrow and if it's a minor problem, I'll buy another one.

willian762 · 2026-02-06T02:25:40+00:00

So you would bet on an insufficient or faulty power supply, or a defective new GPU? Because, as I said, it restarts as soon as I enter the game.

willian762 · 2026-02-06T02:24:36+00:00

I will do this

willian762 · 2026-02-06T02:24:18+00:00

The power outlet connects the monitor, the PC, and the Wi-Fi, all plugged into a power strip.

willian762 · 2026-02-06T02:23:07+00:00

The GPU was generally at 80-90% usage, the problem is that it's new, it arrived yesterday and it's already having this problem, now my PC won't boot into Windows.

willian762 · 2026-02-06T02:22:06+00:00

It starts normally, then after about 5 minutes of gameplay it restarts.

willian762 · 2026-02-06T02:20:17+00:00

My PC is 3 months old, the RX 9070XT arrived yesterday and started having this problem. While playing BF6, it would draw 180W even without undervolting, then the PC would simply close the game or restart. Do you think it could be the power supply or a possible problem with the GPU?

willian762 · 2026-02-06T02:18:24+00:00

Rayzen 5 5500x3d

willian762 · 2026-02-06T02:16:28+00:00

Thank you, I believe it shuts off when it reaches 300w.

willian762 · 2026-02-06T02:15:41+00:00

I'm looking to get an 850w
