Multiple Power Supply Adapter and Daisy Chain Connector, Add2PSU by Genetek Electric (Black)

Worked perfectly

I bought one of these rather than the cable PSU splitters that you occasionally hear horror stories about (catching fire), and also because there were a plethora of positive reviews for this one in particular, even though the price is a bit higher. I've had this in a 6x 1080 Ti rig with 2 850 watt PSU's, for about 2-3 weeks now, and have had 0 issues. The power supply that is connected to this adapter turns on a split second after the main PSU, and if I need to do a shutdown for maintenance, the PSU on this adapter also shuts down a split second after the primary one. This is rock solid. My only minor complaint is it comes with no styrofoam backing like a PCI-E riser does, and it also does not come with any screws. So if you want to mount this to your rig, you'd need to pick up some small wood or metal screws.

Unlike the jumper wire styles that I have had poor results, and smoked PSUs, with before. This one did the trick nicely. Solid PCB, quality connectors, and what appears to be a power regulator chip on board gave me some confidence. I used this on a smaller rig of 6 1070tis. I tied 2 EVGA 850 PSUs in tandem and had no issue providing just under 900w to the mobo. I would have no trouble recommending this adapter board.

It works but it feels cheap in your hand. A bit of foam pad on the bottom would make it far better. The way it is all it’s electrical connections are exposed on the bottom and it’s awkward to isolate it

This thing is a life saver if you're running a multi GPU mining rig. When you need more power, just add one of these guys and another PSU. My only complaint is that the ATX connector is super tight. Really had to muscle it in there. There are a few things that could be improved: I wish there were just a few extra mm of clearance between the components on the board. Some of the more modern power connects have clips and things on them that you have to trim off to get them to fit. It also wouldn't hurt to put some kind of insulation on the back of the board. Electrical tape works, but if you don't have any around, be careful.

Using these to trigger 2x EVGA T2 1600w PSUs. I ordered 2 from PMU PRODUCTS and received 2 with different color capacitors (1 yellow, 1 black), which is precisely where my confidence in this product began to slip. I used the yellow capacitor with 2 PSUs and had a 1 second delay. The black one had the same delay as well. Both Multiple Power Supply Adapters had Sata power connectors. I ordered 2 more from THISON that use a 4 pin molex connection to power the adapter, not Sata, and there was roughly a half second delay. I highly doubt this is an issue caused by the kind of power adapter connection provided on these adapters since these really just trigger the PSU to cycle. I'm not sure why the PMU Products adapter caused such a long delay between PSUs. Silicon lottery? I can recommend Thsion since my experience there was better. I kept one of the PMUs as a backup and returned the other.

I used this to add a 2nd PSU to my server. Connections were tight and it worked instantly. I liked that this version of a dual PSU switch has no cables to get pinched or burned up. It feels sturdy and well-built. The only thing I wish it had is a case of some sort. I plan to 3d print one, but I would have paid extra to have one that comes in a case so the contacts aren't exposed. For now I wrapped it in electric tape.

The product arrived as promised- and with speedy shipping! It is of high quality and is simple to use. Fantastic construction and functionality. The price is superb for a quality product. I bought other items from this company and they all were to my liking as well. I highly recommend products from Genetek Electric.
