Dual PSU Cable Adapter, 24-Pin Power Supply Extension Cable Synchronizer 24 pin to 24(20+4) pin Male to Female for Computer ATX Motherboard 18AWG/1FT (1Pack) (2Pack)

I've checked using four new power supplies including EVGA Gold 1000 watt and Seasonic Platinum 1000 watt and all four will not work with all load connected. I thought it may have been my cables but after tinkering around for an hour or so I just could not get these to power up the secondary PSU. I ended up simply using the jumper block that EVGA sends with their PSU and ordered add2psu for now to have a more reliable switch (even though they were costly).I didn't see anything wrong with the connectors or the pins but they do feel rather cheap. At least it didn't somehow mess up my mobo or any of the PSU's at least. I'm returning these.

Nice cables and showed up super quick (thanks to Amazon Prime). The secondary plug on this harness has pins in a different location than the "jumper" that your PSU was shipped with... THIS IS NORMAL.. This was my only concern and it took a while to find information online about it.​

Great psu splitter cords, I have them splitting 3 psu's for one computer right now and they work great so far, they seem to have fixed the problem of backflowing electricity to the cpu that I had with the ADD2PSU adapters I was using before (the connections are also much less sketchy than the add2psu ones) so I am very happy about that!

not sure if it was my motherboard (ASRock) or this cable but my motherboard is now dead after trying to use this cable with dual PSUs. is there something I did wrong? not sure which is the culprit bad motherboard or bad cable, will be switching cables to be safe

The adaptor was super easy to use and install on my mining rig. This made the job of connecting my two power supplies much easier and safer. I definitely recommend this product to anyone who wants to connect more power supplies to their computer setup.

Worked for a bit, but the third or fourth time I unplugged it, one of the wires on the main power supply plug came loose and I had to hold it just right to get it to plug in again. Then another wire came loose.

I like this better then the add2psu. Add2psu just stopped talking to me, and i had to contact amazon for refund after my package was lost. i'm using this on my mining rigs now.

Great product, works perfect for having two psus for mining turn on and off together when your making a 8 gpu miner
