Musical PSUs (j/k, multiple builds, require guidance)
So,
@triplex1 and a few others have added to another discussion about upgrading my GPU from my RTX3060ti to a gaming rig for a friend's child. Now I'm dealing with PSU concerns.
There are three machines in total.
Corsair RM850x - 5900X, presently an Asus KO RTX3060ti, soon to be RX 6900 XT or RX 7900 XT (hopefully)
Corsair CX650F - 3600X, to get the RTX3060ti
i7-6700 / Tuf Gaming GTX1650S (currently no PSU)
My Corsair RM1000x came in yesterday, which will go into the 5900X.
Because the 3600X build is for my friend's child and the CX650F (80 Bronze) has RGB, I thought about finishing the build with just that one. But PCPP shows a total draw of 454W. I've seen that number multiplied by one and half (681 in this case) should be okay for spikes, so I'm worried it might fail. I understand that the setup can handle 4K at medium detail on a 144Hz DP monitor, but this time it's likely to run at 1440p with high detail.
If that's the case, it shouldn't be an issue to move my original RM850x into the 3600X and the CX650F into the i7-6700/GTX1650S, since the latter uses very little power.
But is everything really necessary? TIA.
Exactly as you mentioned, utilize the Corsair CX650F as a laboratory power source and avoid reinstalling it in the system during tests.
In fact, the 3600X already includes the 80 Bronze CX650F, which makes me consider upgrading it to the 80 Gold RM850x for the RTX3060ti. I’m thinking about moving the CX650F to a lower-power i7-6700 or GTX1650S system. The 3600X was initially built on a B450 board with the GTX1650S, but now it’s running on a Tuf B550-Plus, which will soon host the Asus KO RTX3060ti with 8GB RAM.
The CX650F was bought new in August 2022 and hasn’t been used much. I wasn’t expecting a major overhaul, as I didn’t get any serious offers on it. There have been some parts swaps for troubleshooting other builds, but I’d say this unit has likely been used less than 50 to 100 hours.
The RM850x was purchased new in March 2022 and has accumulated a lot of usage time, similar to the 5900X, which runs almost nonstop. It hasn’t had any problems. Plus, the RM850x is 80 Gold while the CX650F is 80 Bronze. Based on that, I’m questioning whether pairing the Bronze with the lower-power i7-6700 or GTX1650S makes more sense than relying on a high-end RTX3060ti card.
I think it would be better to swap the RM850x into the 3600X and the CX650F into the i7-6700, so I can avoid extra work later. Better to get it right this time.
Also inside a brand, CX-F features a type 4 pin configuration similar to many other Corsair products. Refer to the provided link for details.
I recall seeing different versions like 2019, 2021, etc., but nothing about Type 4 on the RM850x. With the RM850x bought in Mar '22, the CX650F purchased Aug '23, and the RM1000x in Dec '24, do these still share the same pinouts? Checking Type 4 on the RM850x seems straightforward—just like confirming a 18-pin motherboard. If that’s the case, swapping the units should work, adding two more PCIe 6+2s for the 7900XT and proceeding. It sounds like it could be much simpler than I imagined, especially if I only need to replace PSUs in two units and leave one unconnected.
RMx is included in Type 4 as well. Every RMx model shares the identical pin configuration.
