## Description

Your computer will require enough room to accommodate 2 PSUs. You can modify your chassis or purchase one of the Chassis mentioned bellow. This is safe as the motherboard gets power from one PSU only. The second PSU provide power to other components. Both PSU start when the On / Off button of your PC is pressed. Package includes: 1 Pcs Dual PSU Power Cable If you for any reason are not happy with any product supplied , please do not hesitate to contact us and we will do our best to solve your problem .

Review: Works as advertised. - This was awesome to help me set up my quad GPU AI rig. I had (2) 1000W PSUs so I didn't want to buy a complete new 1600w gpu for the test setup. This was a great solution.
Review: This works fine. - I bought this cable to extend the capacity of connecting more than 9 GPUs. This cable helps synchronize the PSUs in order to make them start up right at the same moment. I have tried many tricks but the cable method is the only one that works. I would recommend this cable. It is not that expensive but works pretty well. I have to warn you, though, that connecting the 24-pin ATX cables from the PSUs and then to the motherboard is pretty dang hard. Take your time and be careful not to pull or bent your cable pins. Good luck!

### ⭐⭐⭐⭐⭐ This works fine.
*by T***N on December 25, 2020*

I have tried many tricks but the cable method is the only one that works. I would recommend this cable. It is not that expensive but works pretty well.

### ⭐ Undersized copper, runs HOT, overheating, melting, or fire possible.
*by V***. on November 9, 2025*

As some others report, runs HOT. The copper must be undersized. There's a noticeable temp different touching this cable vs. the same cable that came with my PSU. I don't think this is safe and I think it is out of spec. I won't be using this, going to replace with a normal switch adapter for my second PSU to avoid having to pass all the power through this shoddy adapter cable. Not as convenient but no risk of fire or melting cables...
