Is a Corsair 2025 RM750e enough for a Ryzen 5700X with PBO enabled and a RX 7700XT ?

[AnoN38X]

Hi i had build a new PC with the following Specs:

 

CPU: Ryzen 7 5700X

Cooling: Noctua NH D15 (from a previous build), and about 5 case fans

Mobo: MSI MPG B550 GAMING PLUS

RAM: G.Skill Trident Z Neo 64GB, DDR4-3600MHz, CL16, Dual Channel

Storage: 2x NVME drives (one PCIe 4.0 and one PCIe 3.0), 2x HDD's (one 8TB and one 1TB)

PSU: Corsair 2025 RM750e

 

Now i'm looking to upgrade my GPU from an RTX2060 and the best one i found in my budget is an Sapphire Radeon RX 7700 XT Pure/Nitro+ and i'm wondering if i also enable PBO for the Ryzen 5700X if the load would be optimal with a Corsair 2025 RM750e.

 

PS: if anyone wonders why i haven't went with AM5 that is because AM5 would have been double the cost with just 32gb of ram for a 7600x, i decided to go with more ram while also upgrading to a decent GPU.

Yes, absolutely!  750w is plenty enough for this setup  

Its a solid unit as well.  You can actually get away with a solid 550w so you are more than fine with the RM750e.

 

I ran a overclocked 9800X3D and overclocked RTX 4080 with a Corsair RM750i for a while, I saw around 420-470w full system power draw.

It's 2025 and within the required Wattage, I see no reason it wouldn't do it's job.

Oh and I only upgraded to a 1000w RMx because I expected to buy an RTX 5090.

If I wouldn't upgrade I would have kept my RM750i with the 9800X3D and 4080.  Plenty of power.

Hi i'm asking just to be sure i'm not missing anything but i found a fantastic deal on RX 7800XT and from what i've seen it seems to be the same PSU Requirement as with the RX 7700XT right ?

The difference between the 7700 XT and 7800 XT is 20-30w.

You will still have plenty over power with an RM750e if you get a 7800 XT  

 

No problem at all.

OC version shouldn't need more than 800W PSU:

OC models use the same amount of wattage as non OC models.

no they don't, they wouldn't need extra 8 pin if they did

extra 8pin power might be unnecessary, but still:

SO if i understand things correctly i'm looking at only a max of ~50w increase over the 7700XT and my Corsair 2025 RM750e should still be fine and not loaded to heavily right ?

Correct. You are plenty fine with an RM750e with an 7800 XT  

You could power this system with a solid 550w, even with a 7800 XT.

7800 XT can run on 600W PSU if it's good quality

When you drill down on the system that AMD uses for their "recommend PSU" it lists a 7950x based system. That pulls 235w under load at stock settings. Your cpu pulls 126w stock. They also add in buffer, so all together, 750w is WAY more than enough for what you want to do.
