If you have any questions about how to use multiple power supplies or how to plug your components in, then please post them here in the comments! I also recommend you watch my video on how to safely power your mining rigs here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MIW0i7SlIYI.html And also here's a video of me building a mining rig from start to finish: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TUtr9S4b2T4.html
@Tbird 2013 I’ve had some really high temperatures in my mining location recently and the have held up flawlessly. Since the actual chips barely use any power at all they don’t get warm really, just the temperature of what is around it.
@Tbird 2013 i use molex on all my rigs. maintain good connections (like you would in any electrical situation) use new psu's (2005-above) you are good.
Can you help, i tried this powering my extra rig using this method but the fans start screaming, and LA on hiveos keep climbing, i though its going to explode lol.
Man I love how you explain like teaching a kid not to play with fire and what are the consequences. Seriously ur great at what you do. Pls don't change the way you make videos. Cheers mate
Yeah great video. Your explanations are awesome. I love how you say things twice to really help articulate the point. You probably have saved people from burning their houses down
Good vid, the only thing Id like to remind people is that there is actually small current running the paperclip, and that you can just cut it shorter and cover it with electric tape. The tester cap is probably more safe.
@@SebsFinTechChannel of around 100 rigs I made this year, only the secondary psu died with the plug (that comes with some seasonic and some evga psus). I will now go with the sebs aproved method
This is an excellent guide for using multiple PSUs. Many thanks for creating it. If you're taking requests, I'd say another great beginner's guide would be cooling. Like how to use the fans (back or front), which way to blow air, how to use external fans as you have in your setup etc.. Thank again for the great content.
Luckily i watched your video til the end. I was thinking to use the main power supply to feed all the components + GPUs and the second power supply to feed only the risers. I didn't think what could happen if one of them stop working. Thanks Bro!
Both ran multiple ATX PSUs in chain and installed a dedicated 240v line for server PSUs. Chaining ATX PSUs is SO much easier if you can get them for good prices. Great video
Personally, I think the 3rd way you showed is the BEST way. The using the "Chip" method takes away from an available 6-pin connector you could be using to power up something else. Just my humble opinion. I'm sure someone else probably has mentioned that, but I'm not going to troll through almost 500 comments to find out.
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!
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.
Wow brother, the way you explained everything is so good...im going to build my first rig with two 3090's and im glad I found you...I'll be following all your vids for my reference. Lots of love from India ❤️
Thank you so much for explaining the setup in simple and plain language. I learned so much from this video and now know how to properly connect my power supply and GPU(s). Thanks!
Thanks for explaining connecting multiGPUs in a rig in simple yet best way. I am from IT background and i really appreciate your way of connecting multiple GPUs for minig rig
Omigod Seb you have done it again! Thank you for this video. I am going through every single one of your videos and the posts in Discord Chat with Seb channel and am learning so much! This old school 1980s cobol programmer/desktop builder granny loves getting her hands back into PC components via mining. Day job is management, haven't been a programmer since the 90s. I miss being hands-on! I've been slowly putting my rig together and by trial and error/watching your videos/readings (not always in that order), I am getting things sorted out. I just realized the my 3070 that has 2 8pin connectors should NOT be using one power cable. Thank god I just bought a new psu yesterday so I could hook it up. Unfortunately all I have is the jumper for now, but I did just order your top 2 recommendations and will switch over to one of them when they arrive. I've been getting some weird issues causing my rig to crash that I think will settle down using 2 power supplies, plus its definitely got to be healthier and safer to power my 3070 the right way. Thanks for all you do, you are awesome!
Just as I was trying to figure out how to run a 1000w,850w and 650w without plugging into the asus b250 mobo, Thanks Seb you have helped in my journey, I look forward to your next video man and great work on this one.
Thank you Seb! Just ordered the SATA version of this for my new ATX power supply for my first multi-GPU rig!! It’s made of 3090s (I have limited space so it’s worth it for me to get high hashrate cards). I also used the TRex absolute core clock on them to save 55W of power on each of them thanks to your other video. Keep up the good work.
I used your link today to buy one of those Add2psu adapters, waiting on another card and there is not enough connection on the PSU for many 30 series cards. On these EVGA 3080ti cards, they went berserk with power requirements 3x8 pin and 450w 😲 Great educational stuff man, keep it up 👍🏻
The original video name about better two smaller PSUs rather than big one. So, two PSUs half the power of big one is better because of more cooling 'power', or cooling area (two fans vs. single one). Regarding that connector that should be grounded - earlier days with colored wires, there is green wire that should be connected to the black wire (sensing wire connected to the GND). For anyone who have at least some experience in electronic can connect all that 'green wire' together including main PSU for the MB. Then as motherboard provide the information that all PSUs should run, they will run all at the same time. But your suggestion about special 'thing' is maybe more safe for anyone. Thanks.
I don’t use the atx24 splitter cables , they are not well made in my experience . The pins can move around and cause problems . The add2psu boards are a much better solution. They work totally fine being triggered by other secondary psus and don’ t need to be triggered by the primary . Fan hubs also don’t need to be powered only from the mobo unless you have them hooked up with PWM to the mobo , in that case yes only use the primary to power. Your comments on avoiding cross connecting gpus and their risers is absolutely correct . This can cause all sorts of problems don’t do it.
As someone who has used multiple power supplies in a few rigs, the main reason you'd want to avoid mixing power sources from different PSUs is the effect of minor voltage differences between the 12V rails (which in some cases are not minor), can have on your components. This can be especially dangerous if your grid occasionally experiences brown outs or voltage spikes/drops, as each individual PSU will be able to maintain it's target 12V voltage differently. If the 12V from the riser and the 12V from the PCIe strand diverge too far, this can have potentially catastrophic effects on both the GPU and PSU. I almost killed my Seasonic Prime unit during a brown out, when I accidentally powered the riser of a connected card via Molex from my other PSU, My Seasonic unit was acting as the secondary unit and was connected via the "add2PSU" chip. Luckily with their 10 year warranty the distributor was able to provide me a quick fix (I think a cap blew out), but it could have been a costly mistake. You also really want to make sure you spread your loads in a meaningful way when using multiple PSUs, to avoid loading one PSU up to 100% while the other one works at 60% load capacity. So e.g. 4 GPUs on one PSU & 3 GPUs + MB + fans on the primary (assuming all GPUs have the same power draw and both PSUs have the same Wattage capacity).
@@jkelsall2017 not at all. The motherboard (or rather BIOS) does not care where the power comes from. As long as all required rails of connected components are loaded up with power e.g. switched on when the motherboard gets turned on, then all components should be detectable during boot and that's it.
Thank you for this, I bought through your link! Channel is fantastic, and you seem like a very down to earth guy! I’ve just reached 150mhs so I guess I’m now taking mining seriously, and no doubt I will be hitting the bell and learning a lot more from you! Fantastic content, keep up the great work!!!!
You’re perfect thanks fir all those information ℹ️ you’re giving… i’m here in my first steps to start mining and I think your tutoring is enough for me to go all the way through making my first mining rig… Much respect ✊
Thanks so much Seb… I stumbled on this issue and this video is exactly what I was looking for. And I also want to thank you 🙏🏻 and it’s because of your videos I have been able to put my first mining rig today!!! Thanks a tonne man! 👍🏻👍🏻👍🏻🙌
Hi Sebs, great content! The timing of this video is perfect. I'm a noob miner just recently building my first rig. Safety is top of mind for me mining at home. I've been soaking up all your vids on how to mine safely. Especially with the summer and family vacations being away from the house for extended periods. I'd rather focus on enjoying my vacation rather then being worried about the house burning down. lol I am planning on putting an extra fire alarm and a wireless CO2 extinguisher for extra precaution. Keep up the great work!!
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 🤘💪👌
really awesome video Sebs! im a huge fan of atx's right now. the cost of 1200 servers has gotten more expensive than a 1200w ATX. Since the shuffle began low power atx has dropped 30%-40% in price. I've daisy chained alot of servers, but never took atx past 3. this should be interesting. for those who dont have the patience 8:00 .
Great video. I´m using dual PCU's for my rigs, going way overboard too. 2x corsair 850w on rig 1 and 2x EVGA 850w on rig 2. both draws about 1000w. they barelly gets warm, and using just a simple cable to short the start on the slave PCU. have them connected on 2 GPU's each(risers and gpu). Also have them connected on different fuses(the 2 corsairs on one fuse and the two EVGA on another). I´m mostly working away from home, and my offtime i usually spend in my cabin, so trying to think about safety(mostly of my neighbours).
Yeah i did the same on purpose, in case one psu fail, its could running immediately with 50% capability of my rig while im buying another new one. But im always keep spare for psu & mobo in hand.
awesome vid man, i'm surprised you don't use server psu's, they tend to be much more efficient and the 80% rule doesn't really apply because of this...plus their way cheaper. Are they hard to come by where you live?
Just came back to this video. With the merge, I need to be able to turn off and on my rigs via hive which I can't do with server power supplies so need to have 2 atx power supplies on one rig. Anyway, thank you for this content.
Good job. Thanks for the video. GPU and Riser on the same power unit. OK , but what if you have a PSU with 2 or 3 12v rails on it. Do you need to power gpu and riser on the same 12v rail or you can use one 12v rail for only the risers and another for only the gpus ?
