Is this a good (safe) idea. I'd like to not die.

I have the wifi version of - 1200.58ZAR |Rd Riden Rd6012 Rd6012w Usb Wifi Dc - Dc Voltage Current Step-down Power Supply Module Buck Voltage Converter Voltmeter 60v 12a - Voltage Regulators/stabilizers - AliExpress for power injection / troubleshooting electronics / charging cells etc.

I used a old laptop PSU (19v 3a) which works fine. I have a old Corsair RM650i lying around, which is missing the 24pin ATX so I cant use it currently without buying that cable.

I want to use the RM650i (GPU 12v) power cables to power the RD6012 as the PSU has a zero-rpm fan and should provide much cleaner, more stable power as its Gold+ and wont need to output more then 72W (pity as 20% of the PSU's 650W would hit a "highest efficency" point, being 20, 50 and 80% in most cases).

I plan to cut the GPU's cables, solder the ground cables together, and then the 12v cables together. This will then be connected to the RD6012 and have heatshrink added. Final unit will be built into a open little woodern case I'm making for this project / tool so the fan can pull in clean air without any resistance.

Is there anything I'm overlooking or simply not aware of?

Why do you need the 24pin atx cable. Just bridge the necessary pins and you are sorted. You would anyway want to use the 8 pin gpu and cpu cables for the 12v supply. I’ve done similar to power all sorts of stuff.

Would be good to add fuses though and to make sure cables and properly soldered / heatshrinked.

That's what he said he'd do lol.

He can't use the PSU as an actual PSU for a PC due to the missing cable, hence it can be "sacrificed" for this project.

Good idea about fuses though.

What other projects have you used these for?

Ah, I missed that. Read it that he needs to buy the cable for this project to work instead of use it for this project instead of buying the cable. 🙈

Used it as 12v bench psu and recently also to power multiple external disk drives at once instead of individual 12v psu per drive.

Good idea re the fuses, thank you. The RD6012 unit does have a fuse built in, can't recall the specs.

All 12v rails on the RM650i can do 40amps and the RD6012 can only do 12amps, so all good there in terms of only having to butcher the GPU cable.
