2-Pack Add2PSU Multiple Power Supply Adapter (ATX 24Pin to Molex 4Pin) and Daisy Chain Connector-Ethereum Mining ETH Rig Dual Power Supply Connector

This little device is perfect. In PC, I have a 650 Watt power supply and a 3070ti. I had a 3060 and a 2070 on risers outside of the pc. I wanted to be able to run everything off one pc, so I bought this. (I had an extra 600 watt power supply lying around)....I simply plugged in a 4 pin connector from my main PC to this device. Then I plugged in the 24 pin connector from my extra power supply....Made sure my two external GPUS were all and only connected to my external power supply, and thats it. It has worked great since. Of course, I had to run two USB wires from the risers in my case so I could plug into the PCI express slots, but yeah. It works wonders! Thank you! Cheapest solution yet!

Product was very easy to install I added to new PSU to my mining rig to a grand total of 3 PSU. Rig works like a charm. I highly recommend this product. Above all super fast shipping.

It's work fine

What more can i say? It works just as intended. I run two psus for my mining rig. A 850w and a 750w. Works like a charm and I'm glad it has two. Would pay this price for just one.

These cards allow you to power up multiple computer power supplies at the same time.You simply connect a 4 pin molex from the power supply that is hooked up to your motherboard, and then plug in your new power suppliy's motherboard cable to this card. That is it.When you shut down your main power supply, this will shut down the secondary one too.It is very easy to use, and lets you hide your secondary power supply out of the way.

I was able to chain two power supply together to my mining rig, the master power supply controlled the 2nd power supply with no issues.

Good product, did as intended, however one arrived DOA. Do check both units after receiving. Been going strong for 12 months

I was convinced after troubleshooting for about an hour that both of these modules were DOA. I researched for about an hour on reddit and google trying to find information on why I could not get these modules working and everyone said that they were probably DOA. I checked connections multiple times, power cycled numerous times, etc. and nothing seemed to work.I came across someone on reddit saying that they had used the MOLEX power cord that came with their 2nd PSU on their primary PSU thinking it wouldn't be a big deal, and after using the MOLEX cable that was provided with the FIRST PSU, it worked. I ran out of options and didn't think it made sense, considering both of my PSUs are the same brand, same model, but the 2nd PSU is a newer version of the 1st PSU.After using the MOLEX cable that came in the box with the 1st PSU, it worked immediately. I was very surprised to see this. After using this cord, my system has been online ever since and have had no issues.I only gave 4 stars because the padding beneath the 2nd module was not applied properly. Aside from that, the product works as intended.

If you really need it, go for it.

These do what they’re supposed to. Quick delivery, had my back when eBay was a complete letdown.Give them a try if you’re in need of their function.

It works! Modern PSU x 2 850W EVGA G5

These work perfectly as intended. No issues at all.

Absolutely garbage. Works sort of. When running two power supply’s second needs to start first. Most of the time anything attached to this (second power supply) is not found.Plus it started to smoke and burnt out pins on the atx 24 pin on the power supply. Could have caught fire if I did not see it.Stay away from this. If you need to run two power supply’s you are better off using a atx tester that leaves the second on all the time, or jumper pins 3 and 4.
