2 Pack Synchronous Power Board sata Dual PSU Jumper Multiple Power Supply Adapter and Daisy Chain Connector add2psu Adapter with Sata ATX 24pin to Molex 4 Pin Connector(2pack)

I was determined to fit two 5080s in a Lenovo P620 with Threadripper. And this product solved the problem in getting the RTX 5080s to post. Installation was straightforward. The power supplies turn on and off together. And I no longer fear the "magic smoke." The positive reviews for this product really helped me make a decision to purchase.

Works beautifully to control an external PSU for supplemental hdd's in an external cage for my nas

I put this in a Dell computer (older) I added a external PSU, because the stock Dell PSU was only 250 watts and I needed more wattage to run a new graphics card, it required minimum 400 watts. This module triggers the secondary PSU to start at the same time as the Dell PSU inside the desktop. From my research its really important to make sure if you run a 2nd PSU that they both start at the exact time. This module does exactly that. I've had it for about 4 months now and no problems. Great solution if you want to have a 2nd PSU. Now all I have to do is hit the (ON) button and they both start up. The same when shutting down the desktop, both PSU's stop at the same time.

These allowed me to connect another case to house drives and control the second supply for my Truenas scale.

Very easy to snap off when removing from computer
