I'm just getting started with my first rig. After watching this video I really get how to power my rig safely. You're an excellent teacher. Thanks Seb.
@@SebsFinTechChannel Please help me out. I want to use two 3060ti FOUNDER EDITION card with one 8(6+2) PCIE cable using PCIE splitters. Means my one PCIE cable have dual 8(6+2) Pin, I want to connect one PCIE splitter into one 8(6+2) Pin and one PCIE splitter into one 8(6+2) Pin. Now I want to connect two 3060ti FE card and two riser simultaneously with one PCIE cable using two splitters. Please suggest me is it safe means I can connect this ? I am waiting for your reply thanks in advance. Love 💘 from INDIA
It would good to explain how you got 300 W rating for the cable in the beginning. With research I think I was able to deduce that you have a 16AWG cable which means each cord is rated for 13 amps (10 amps for 80% rule). Using red fox crypto's info about how much voltage is drawn through the PSU for each pin (which is 2 pins and 12 V from PSU) we get 13x2x12 = 312 W (240 W for 80% rule). Just incase anyone was wondering how he knew the VGA cable can draw up to 300 W (240 W for 80% rule). Thanks for the video!
I've been studying maximum power capacity of all of the components involved in wiring up my GPU's and nobody ever explained that the female connector "asks" for the power and the male connector supplies it (through the cable). Now that I've watched your video, the way you've explained it makes it CRYSTAL clear! Thank you Seb for all of your hard work and detailed explanations!
I rarely ever comment on a video but this my friend is by far the best explanation on power to the rig I have seen. Everywhere else the explanations are confusing and hard to follow. That said, here's a like and a sub!
Just started very basic mining and trying to understand this whole world. This video is one of the best I've seen on how power is drawn and used by the components. Thank you Seb.
Thanks Sebs, I just had a delivery of 4 x 1660 supers plus 8PIN to 8PIN M2M and 8PIN F TO 2X 8PIN M and you provided the exact information I needed to ensure safe wiring. Looking forward to running 6 x 1660 supers + 1x Rx480 8GB later today and the increased hashrate with low tdp (averaging 31.9 @67w). Installed on a BTC37 S37. Thinking of making a video my self and crediting you for safety tips. Hope that's OK?
This video helped soooooo much more than everyone else's, thanks for the step by step examples that was extremely helpful, got my 185hashes on the network safely now!
Just want to say, that all your videos have been super helpful. I even built the rig you designed. thank you again for all the helpful videos and even your video on start to finish was super helpful!
Thanks for this video! Everything inside, for what I was interested before I start with my very first rig. You have the answers for all I wanted to know. :)
Intend to use a 1000W PSU for 4x RTX 3060. The PSU got 6x PCIe (6+2) out. So i take one pcie strand for each 3060. And then use two splitters on the last two pcie strands to power the risers.
I been binge watching your whole content as i am getting into mining and building my first rig soon, thanks for the amazing tips and ways of explaining things. I have learnt a lot!
Really amazing video for a beginner like me, i've searched everywhere including reddit for all the questions i had in my mind, and you've easily answered all of them in this video. Thank you so much. Liked and Subscribed.
A quality cable from a brand name PSU would do much more than 300w. But the limiting factor is the 8 pin. Hence molex is safe for 2 riser if its a 6 pin in psu side or 3 risers on 8 pin at psu (288w limit) also you can use close
Great video! I had watched other videos on this topip and I still had some doubts. But this one has absolutelly clarifays the thing. Thank you so so so much! :)
I put 3 risers on a molex cable. and after a 6 months, melted my psu and psu connector port. So dont be like me, be smart - use PCI-E and splitters. :D
Seb you’re a great teacher. let me ask you something: is it worth to start mining eth today? with 4 RX 6600 and electricity cost of 0.16. Also considering that you can buy eth cheap today or even 10K RVN with less than $500 usd. I know it’s up to me and I’d like to experience mining but also want it to be profitable
So, let's say I have used a power supply to power my motherboard and ssd and so on. Am I able to use the same power supply to go on and power some of my GPUs? Noting to stay under the 80% rule? Eg: 1 PSU powering my MB+peripherals And then powering x2 or more GPUs and risers (staying under 80% total load. Then using a second power supply to power more GPUs and risers.
I have a 3060, 1660 Super, and a 2070 Super Undervolted running on a 750W PSU pulling about 390-395 Watts at the wall. I may just get a 1000 W PSU to be on the safe side. 1660 Super is on a riser. Everything has been running fine for the past 24 hours. Thoughts?
Let’s see. So let’s say your rig freaks out and all your undervolts reset and your GPUs go back to pulling 100% TDP, that’s 170W for your 3060, 120W for your 1660 Super and 215W for your 2070 Super. Add another 150W or so for the rest of your system and that comes to 655W which is more than 80% of 750W. So yeah I’d definitely say getting a more powerful power supply is a good idea from a safety standpoint :) Good luck!
very good video, can u also make a video on how to calculate max power we can draw out of a wall plug ? i simply add an extension to a wall plug and draw all power from it , apparently this is the wrong thing to do as wall plugs also have a limit , this can also be a fire hazard
Very interesting video and answered some questions I had with no answers until now 👍. 1) How to power the extra connectors of the MOBO? With the same cable for all connectors or each connector with its dedicated cable from the PSU? 2) Imagine a GPU with 2 connectors running @ 120W (RTX 3070). Does it mean we can plug in it a 8Pin+risers instead of connecting 2*8Pin + risers? Does it will work?
Cards draw most of the power from pci e cables and some from pcie slot both at idle and under work as shown in the video of Linus Tech Tips Nvidia Pcat tool video
Seb congrats on 4K brother, I have a question today, can I use one Psu to power all my main components (ram ssd motherboard) and one or two of my gpus (with risers) and the second Psu for another 6 gpus with risers ? Would it be safe to run ? Thank you, love the content brother !
Thank you Avinash! Yup absolutely that is what I do in my rigs. I recommend looking up a bit more information about running multiple power supplies for one mining rig but it can definitely be done safely. I recommend using an “Add2PSU” chip to link the power supplies together. Good luck!
Thank you so much Seb! Will do more research regarding 2 psu ! If you ever make it to Malaysia, hit me up man will gladly host you and show you around. Take care and stay safe !
But what about feeding two different GPUs female pins by one split cable (8pin from PSU to two 8pin cables (divided by a splitter), one 8 pin to a gpu and other to the second gpu), taking in account that the total amount of power will not exceed the lets say 240W limit. Will they somehow interfere? Is there anything like different frequencies of power consumption between the two GPUs, or some rule like "never plug one cable(that comes from PSU and then divided by a splitter) to multiple different devices, even if the total amount of power will not exceed the cables limits?
In other words, am I allowed to do this? 1. From PSU one 8pin cable 2. Divide it with a splitter 3. Power one 1660 Super with one cable from the splitter 4. Power a second 1600 Super with one cable from the splitter
Seb you did not explain for cards with 2 a pins and a riser with a 6 pin how many leads you use ? Can 1 l6 pin lead from a server PSU run a riser 6 pin + two 8 pins on a GPU for those 3 connections in total?
Hi. I'm not overly familiar with server PSUs but all the same principles apply to GPUs no matter how many pcie ports it has. If a cards TDP is 320W, it can ask for up to 320W divided among the PCIe connectors on the card and the riser. Look up the TDP of your card and then make sure each individual cable can handle the max power the cards can ask for on that cable.
Hi Sebs, really congratulations for your videos and for the simplicity with which you explain complex topics. I want to ask to you: can I use 2 splitter (as you show in the video) to power, 2 AMD video cards + 2 riser (through 6-pin female) with one only cable, or I should consider that 1 video card asks for 150+ 75 watts and for this reason I would go over power with 2 video cards?! Thanks a lot
Hi mate, can I get your suggestion on how I can power 10 1660 super GPUs using an ATX PSU? I'd like to use ATX because server PSUs produces loud noise. Can you suggest which PSU should I use that will be enough for 10 cards?
