Will 750W run most binned 6900XT (AsRock OCF 400W)

Can 750W support binned 6900XT

 

Hello everyone. I have brand new Seasonic GX-750W 80 Plus Gold PSU. Currently there is a deal for AsRock 6900 XT OC Formula, I'm looking forward to buying it, but I'm skeptical if my PSU can handle it. AsRock says recommended PSU 1000W. 

 

Should I buy it and undervolt it? It's a great deal here in Europe, and I really want it. I've been looking for "normal" 6800XT/6900XT. Btw it's 649€ ~ $705.

 

This is my setup:

•MB: AsRock B550M Steel Legend

•CPU: AMD Ryzen 7 5700X (Stock)

•RAM: 2x16GB 3600MHz Corsair Vengeance Pro SL CL18

•Storage:

- 1TB Kingston KC3000 PCIe 4.0 NVMe

- 1TB Patriot Viper VPN100 PCIe 3.0 NVMe

- 1TB Toshiba 7200RPM HDD

- 500GB Seagate Barracuda 7200RPM HDD

•Fans: 5 x 120mm Fractal Design Aspect 12 RGB PWM

•Case: Fractal Design Pop Mini Air White RGB

•PSU: Seasonic GX-750W 80 Plus Gold

 

Seasonic is high quality PSU so I wonder if it can handle it. I don't play newest AAA titles just Rust & DayZ @1440p. I don't planplan to overclock any of my components.

I have this exact card, and during gaming I see loads of upwards of 325W at 99% utilisation.

 

I don't know how your PSU will do with transient spikes tho, as Seasonic's OCP can trip it up.

I run it on a 850W just fine, I have to say the card is quite loud as the fans kick in and I undervolted it personally to keep the temps a bit more in check.

Shouldn't be a problem, PSU recommendation on product websites are calculated based on the most power hungry CPU+the peak power draw of the GPU+ peak power draw of the other parts.

Seeing as your CPU is 5700X, 750W should be fine, your PSU isn't bad anyway.

3x8-pin = 3x 150W + 75W slot = 525W on 12V just for the GPU.

 

Your PSU ~748W on 12V.

 

Considering the 5700X bottlenecking the card on 1080p and 1440p, you'd probably be fine.

And it only does about 410w when you oc it to hell and back. This is the most I found and it was a highly inneficient oc

 

If you switch to the normal mode its just another 6900xt or even stock its fine

I've bought it. It works fine. GPU PPT Limit in hwinfo is 325W, when I play aroung in Radeon Adrenaline software with Power Limit, Voltage etc. PPT Limit changes. I'm satisfied with this and had no problems with stress testing, benchmarks and gaming. Thank you everyone, this was a great deal in Europe, since there are litteraly no deals in my region (Eastern Europe).

You'd probably be fine. It will be bottlenecked by the CPU at 1440p anyway, so won't draw that much power.

There are 2 options to finding answers apart from guessing:

1:There are Web applications like this one : https://outervision.com/power-supply-calculator

2: There is AMD's minimum PSU recommendation for the card you're looking at which comes out to 650watt minimum.
