Question Musical PSUs (j/k, multiple builds, need advice) ?

[Anomaly_76]

So, @triplex1 and one or two others have chimed in on another thread regarding a GPU upgrade arising from donating my RTX3060ti to a gaming build for a friend's kid. Now I have PSU questions.

A total of three machines involved.

Corsair RM850x - 5900X, currently Asus KO RTX3060ti, soon to be RX 6900 XT or RX 7900 XT (hopefully)
Corsair CX650F - 3600X, to receive the RTX3060ti
i7-6700 / Tuf Gaming GTX1650S (currently no PSU)

My Corsair RM1000x arrived yesterday, which is going in my 5900X.

Since the 3600X build is for my friend's kid and the CX650F (80 Bronze) has RGB, I considered just completing the build with it. However, PCPP indicates a total 454W draw. Since I've read 1.5X that (681 in this case) should be allowed for spikes, I'm concerned it may not hold up. I know that setup should be able to handle 4K at medium detail on HDMI (it's done it before without issue), but this time it will likely be run at 1440p with high detail on a 144 hz DP monitor.

Should that be the case, it's not a problem to put my original RM850x in the 3600X, and the CX650F in the i7-6700/GTX1650S, since the latter doesn't require much power at all.

But is all that really necessary? TIA.

Just like you said, use the Corsair CX650F as a lab power supply and for some tests, don't even think about putting it back into the system.

You should be fine;

How old is the CX650F, though?

As for your last liner, yes you should be good to hand down the PSU's...to the builds lower down. That would be my logical upgrades for the partial builds listed in your OP.

Actually, the case with the 3600X already has the 80 Bronze CX650F in it, which is why I'm wondering whether I should upgrade it to the 80 Gold RM850x for the RTX3060ti and move the CX650F to the lower-power i7-6700/GTX1650S rig. The 3600X was originally built on a B450 board in this case with the GTX1650S, but is now on a Tuf B550-Plus, soon to have the Asus KO RTX3060ti-8GB-OC.

The CX650F was purchased new Aug '22, with very little use. Originally planned to flip the system but never got any serious offers on it. Since then, there's been a bit of parts-swapping for troubleshooting other rigs. But I would say this one has probably less than 50-100 hours on it.

The RM850x was purchased new Mar '22, and has a ton of hours on it as the 5900X has pretty much run 24/7, rarely being shut down. No issues though. Also the RM850x is 80 Gold and the CX650F is 80 Bronze, so I'm wondering if just based on that difference alone the Bronze should be paired with the low-power i7-6700 / GTX1650S, rather than trust a pricey RTX3060ti card to it.

And it sounds like you think it would be better all around to put the RM850x in the 3600X and the CX650F in the i7-6700. More work I was hoping not to have to do, but I'd rather do it right than do it twice.

Yes, you will do that.

Not that much. RM850x and CX650F use the exact same cables. In de 3600X machine you only have to switch the PSU.

Seriously? If so, that would save a lot of cable management. I've heard a lot, though, about using cables from PSU to another is a no-no. Or is that just from one brand to another?

Also within a brand. CX-F has type 4 pinout like a lot of other Corsair units. See https://help.corsair.com/hc/en-us/articles/17759727689997-PSU-CORSAIR-PSU-Pinout-Diagram

Question. I remember seeing variations of 2019 version, 2021 version, etc., but nothing about Type 4 on the RM850x.

So with the RM850x purchased in Mar '22, the CX650F purchased Aug '23, and the RM1000x purchased Dec '24, does that still mean they all use the same pinouts?

Is verifying Type 4 on the RM850x as simple as verifying 18-pin motherboard out? If so, I should be able to just swap the unit itself, add two more PCIe 6+2s for the 7900XT, then call it good, right? If that's all there is to it, that would be awesome.

This might be a lot easier than I thought, I was expecting to have to recable all three. If I can just swap PSUs in two units and only cable the one with nothing in it yet, that should work out nice, with a lot less work.

RMx is mentioned under Type 4 too. All RMx have the same pinout.
1st model RM has different pinout than 2019 and 2021 model.

One other thought. I had planned to run my NAS from the same PSU, but the seasoned will already know that didn't work out. The NAS is to be a 1700 Ryzen, stock clock, GTX1650-S, with SATA SSD and switched access to the 5900X's HDDs. PCPP calls it at 308W, so a 450W would do. This setup ran on a CWT GPT500-SA for about five years, so obviously it's not picky or power-hungry. I wouldn't think interchangeability per the previous info is really a thing here with the wattage requirement.

However, the Amazon employee strike means I may not even get that RX 7900 XT on time (not dire, as I have a GTX1650 to stand in once the RTX3060ti is transplanted).

The local Best Buy has a ThermalTake 700W for $50 and Corsair CX650M for $65. Are these worth the money? And if not, what other options do I have for PSU?

The Thermaltake is probably a junky Smart 80+ White or TR2. The CX650M is way better and really worth the extra $15. Is the MSI A550BN available, or Thermaltake Smart BM3, Adata XPG Pylon, Adata XPG Kyber?

Not at Best Buy, probably my only expedited option ATM. And while it's not necessarily imperative to get the NAS back up and running, I'd rather do this all in one shot. Probably just go with the CX650M, I don't really see one of those blowing up with a 200-300W load.

Well, all is sorted out... and of course, after about 4 days of testing, tuning, and optimizing, the kid decides to reinstall Windows 10 Home and wipe out Win10 Professional 64, Ryzen Master, Precision X1, and all the optimizing I did. Now my friend's asking about Windows license keys. Since the only license keys I have are for Pro 64, I just told him to Google cheap Windows keys. His kid will find out soon enough he doesn't know everything. 🙄
