In this video I go over the 4 different ways of how to use multiple power supplies in one mining rig. Using 2 or more power supplies in the same crypto mining rig can be a great way to save money, as it is usually cheaper to buy two lower powered PSUs than one high powered PSU. For example 2x 850W PSUs will usually cost less than 1x 1600W power supply. And with the techniques I show you in this video, you will be able to plug 2 or more power supplies into your PC or mining rig safely. In the video I go over the techniques from worst to best. The most basic and “worst” way is just using a paperclip or exposed wire to trigger the 24-pin circuit on your secondary power supply. The second technique is very similar just using a cap for the 24-pin instead. The third technique is very common, using a 24-pin atx psu splitter cable that lets you plug 2 PSUs into the same motherboard. The fourth and recommended way is using what is called an Add2PSU-chip. These clever little Add2PSU chips lets you daisy chain multiple power supplies together safely and works by letting your primary PSU trigger your secondary ones to start instantly. Finally, I also go trough how to safely plug your components in when using multiple power supplies in your mining rig.

None of the content in my videos or elsewhere is direct advice, financial or otherwise. Everything said is from my point of view and for entertainment purposes. You do things at your own risk. You are responsible for your own actions. Do your own research.


  1. Just a random question !!!

    With regards to the "on/off" switch on the back of each individual power supply… do they both stay in the ON position once plugged in? Do you have to power on the main power supply before powering on the secondary power supply? (E.G the order?) would there be any consequences if you powered on the secondary power supply, before the main power supply is on?

  2. But what if my mother board needs a specific psu so I would use the dual psu but I don’t have the 24 pin connection on my mother board so I would put the 24 pin into the adapter and use a sata cable? Can you show how to do that?

  3. This also works if I wanted to connect an additional psu for my day to day with windows? not only for mining, maybe for gaming too. And if it works, which of the two do you recommend? the splitter or the chip?

  4. Very good information, you answered some basic questions that bothered me. I'm an electronic technician but don't know anything about mining. A couple of suggestions: If you make videos like this in the future, you keep referencing your first choice as a "chip"; however, that is a BOARD and not a chip. A chip implies an integrated circuit and the word chip comes from the actual silicon wafer ie, "chip" that is found on all IC's. So I would use the word circuit board and more correctly you should say relay board because that orange component on the board is a relay that once it is powered on or energized by the main power supply it closes the contacts in the relay that then signals the next power supply to power up. Also when you explain the need for keeping the power supplies separated at around the 13 and 14 minute mark, you mentioned that if one power supply fails and that certainly is a valid concern, but from an electronics perspective, there is always the possibility and I would say the likelihood that no two power supplies will generate the exact same voltage even though the label on the power supply says that it does. You may also notice a plus-minus percentage as well telling you that the voltage will likely not be exact. So the most important reason why we want to keep power supplies apart is so that they don't get into a situation where one voltage is higher than the other supplying the same graphics card. That is a real world and very frequently occurring design issue. Your stipulation to never mix power supplies is well-founded and I wholeheartedly support that. Thanks again! Great video, and of course I gave you a thumbs up.

  5. very very nice your just a hero i was looking for exaclty that information in the whole web but didnt find the full explanation but you nailed it
    keep going with your amazing tutorials 🤘💪👌

  6. The best video i have seen since I started mining one year ago. I got rid of my server PSU. It was very efficient, but way too loud and hot. I got ten rx5600xt gpus and got myself one RM650 and one RM750 for 100 Euros. Both are very quiet, the system is stable. Since the rx5600 runs on lower watts, I can use one cable to run two cards and two risers!

  7. I know sata power sucks for risers, does it also apply for the add2psu method? Can I safely power my add2psu using a sata rather than a Molex without running into issues? Thanks
