    I have a GTX 1050 Ti. Need to connect with risers. It needs additional 6 pin power supply as well. So how can I connect it with the risers? Do I need to supply power for both graphics card and riser as well? Or is supplying power to the riser is enough? Cos' It has overclock feature and I use it for mining. Please help me to solve this issue.

  • Michael Kwan

    Clear and concise. Thank you.

  • Giovanni P.

    Bottlenecking 101? isn't that going from 16 lanes to 4?

  • TheMaxAcceleration

    How can a USB cable connected to a x1 PCIe transfer the same amount of data, then using the graphics card directly inserted into the x16 PCIe? I'm not a miner, but I can't imagine that the card will have the same performance. I mean... it uses only fraction of the connecting pins of the motherboard's x16 PCI-e slot.Please, drop me a line if you have a reasonable explanation... Thanks!

  • Roman Matěna

    dou you have any experience with connecting b250 mining expert and server psu? how to do it?

  • Alzakiel

    With the rubber under it. Can i just plug-it and make the extra GPU sit next to the pc on my desk safely ? (Since im just trying to add some extra power from an old card even if it will probably not give much more and don't have many GPU to make it worth buying something to support them in the air)

  • Chris H

    So I cant help but be curious. If I am trying to run 2 GPU's either crossfire or sli on a mobo with one PCI x16 via a riser that has 2 PCI x16 slots. Wouldn't there be some type of bottleneck using only the one slot?

  • mariano passerini

    I FUCKING LOVE YOU MATE. i'm from argentina and my english is kinda advanced so i had to serach videos about this on english and you are the first of like 20 vids that say things in a way that i understand thx <3

  • The Shadow Man

    Thanks for the video, it helps

  • peterz zylstra

    what the cables that if I was use for the PSU to the gpus( I am a first timer building my PC 1 into 4 GPUs......I need those steps...i have a separate PSU but not sure what cables are needed and what gets plugged in where...please more details...

  • Derya Gokalp Yilmaz

    i have a lga 775 Mbo but i wanna install 1050ti or greater something but my x16 is gen 1.0. Now newer graphics cards have 3.0 x16. I was wondering if I get a PCI Express Riser cable or something like this would help me out performance wise?Asus support tell me it will work normal way just plug it but wont get max performace.

  • AntaRESynth

    can you connect the riser at the pci bus? If the card doesnt have 6/8 pin connector and draws power directly from m/b, can you connect 6 molex to the psu?

  • Qorqud Alekberli

    Must i use power cabel when am using gt 730 or any graphics card like this?pls answer this

  • Juice

    Question: So when I do this I should NOT plug in the six pin power supply cable from my battery into my gpu? I just destroyed 12 Graphics cards...Help.

  • tomcio malina

    My question is, if my original PCIe x16 in motherboard is broken (not snapped) just doesn't detect any gpu. Can I use this riser to get the GPU working ?

  • 1secondGHOST

    Needs close ups of the board. Most the screen is a desk

  • Son of a Beats

    i just want to ask, my system unit is a slim type then i bought a gpu. but the gpu wont fit because the other ports is just so close to each other. will the pcie riser card help me in my problem? i dont know much about the technical stuffs, thank you in advance!

  • Attila Vidacs

    Aren't the molex ones the worst to use?

  • Tech Master-All Tech You Need

    Can i connect riser into my pci e 16x??

  • Marco Wiegand

    On x16 Slot is a x16-Riser better. Graphicscard or Graphiccard ?

  • RoiPourpre

    Hello, this can carry a GTX 1070 Amp extreme you think ? I wont loose any performances ? Ty.

  • Zeeshan Ul Haq

    cant i just connect the usb cable direct to usb slot

  • cookytrix

    i have hooked up one on a small slot and my pc is not recognizing it. is there a driver or something im missing? i have a gpu on the 16x also and it is recognized. my first time so i dont know what to expect.edit: i reinstalled nvidia drivers and seems ok now... oops.

  • P R Sudha Rani

    THANK YOU SO MUCH!!!!!!!!!!!

  • Jacob Regamey

    How do you add extra power if 8x isnt powerful enough?

  • David L

    but then where should you put your GPU coz it is not installed on the motherboard anymore, it will be outside the PC's case.

  • Tay TYLERIENMAM Station

    how do i Mount it in the bracket?

  • john hoon

    Hi , can this PCI-E 1X - 16X USB Extension Riser Cables set use for SSD M.2 NVME or NGFF

  • Psn Distend_

    Can you use a pci e riser and with a graphics card inside and while running a graphics card in the mother board to boost gaming performance? Btw this is not for mining only for gaming

  • Rakly3

    I have a power issue with these exact same riser you are using in this video. (Black PCB, black PCIE port. black 4p molex connector.Mu cards seem to connect and disconnect every 2-3 seconds.Now on these particular risers the PCB says 12v grd grd 12vWhile a normal 4 pin molex is 12v grd grd 5vThey also have jumper above pin 2 & 4 and 8 & 10 of the pcie slot which I can't find on any other riser.But I can't seem to find any documentation on this.Do I have to rewire the molex connectors? (I know how to do it and have the equipment, don't worry)It just seems very odd to me if that is the case since that isn't a standard connection on 4p connectors.Edit: Hmm, maybe they are not exactly the same afterall. When I google for these all black risers I get those that look the same, but without the jumpers and molex connectors that are 12v gnd gnd null

  • Cees Timmerman

    Wouldn't connecting a x16 card via a x1 slot give 1/16 performance?

  • Network IT

    awesome video. I tried for months to figure out how to install a riser and didn't find a solution, and then I found your video. I helped a lot . Thank you. Keep making videos like this

  • Rahul Chettiar

    Ok, I will watch the entire video. I need something like this, because my Z68 boards PCI 16 has some problems and I want to use my GPU in PCI 1 via this.

  • Kamil Wendland

    Hello. Can I connect graphic card that should have pci 3.0 to motherboard wich contain slot pci 1.0 by riser? It will be lost data by this?

  • Sommo Deb Dhali

    can i use Dual GPU like ,, in my Motherboard and One in PCI riser

  • TheRealJiff

    Great video. Clear and to the point.

  • TheDefeatest

    So could I use one of these to add a decent gpu to my small dell optiplex case that is too small for a gpu of any size? I would have to modify the case slightly and keep the Gpu on the outside....but it that a way this could work?

  • Spykerhond

    the bloody 1 x sockets sit very loose during operation , dont you know of some plug sheeth or cable grippers to stop riser boards from moving sideways in the slot during operation ?

  • Ben Nguyen

    So does the x1 channel have enough bandwidth to work with that x16 GPU card?Conversely, if you could theoretically fit 4 of the those 1x extenders into a single x16 slot, you would have four 16x GPU cards on one 16x slot.. so what am I missing?

  • philip dias

    Can this be used with other cards than videocards?

  • edgar wahl

    The nrext is, How i can identify the graphics GPU with this. I have the LINUX Server with an X3650 M1 and the HP proliant DL 180 G6. I was able to make self Elektronic boards. I have the same risers that you using, but the 6 Pin Connector. I can using a 12 V 150 Ampere DC industrial DC Converter 240 / 12 V and also a / 5 V / 100 Amp Converter. Only what drivers you had to use

  • DANI VaiRos

    I have an ACER ASPIRE X3995 device and I bought a new graphics card GT 1030 zotac and connected it directly inside the computer with the motherboard .. but the problem is that motherboard did not recognize the card maybe because it is an old version !!If you install such a piece it will solve the problem and will work the device well??

  • Yiu Chung Wong

    Sorry for being a noob but does it draw power from the motherboard or external power?

  • IMineBlocks

    Please Note:- You cannot connect the GPU Riser to your USB port. The usb cable is just used as an alternative to a ribbon cable, there is no usb interface. You cannot run the gpu riser from a usb port!

  • MrUniman69

    That is a well presented and very useful piece of information, thanks for making it.

  • Jomaster The Second

    Would this work for gaming??

  • Paul Rhodes


  • peterz zylstra

    can i add a second PSU 1200 to 1600W to the risers to aviod a shortage, can i just hope that the current PC PSU can handle 2-4 more gpus

  • Aryan Tiwari

    Can you connect a GPU to a laptop using this method, using mpcie adapter for the wifi card?

  • Levente Varga

    having sen this short tutorial,...this is my very first time signing up for any videos..ever!!!! Good straigt-to-the -point video, I hope there will be other great quality vids to be seen!

  • ๖ۣۜ KENNEXS

    Great review pretty much pro

  • Blender Rookie

    I have a question, I'm not into cryptocurrency mining so my question has nothing to do with that. I do use a program called blender which is a 3D Graphics program. It uses gpus to actually render images but the rendering is not typically done in real time. Does anyone know if using one of these risers will work in a program like blender.

  • Cybercity007 Gaming Channel

    Nice explanation dude great work !

  • David L

    yes, he was right, graphics cards come bigger and bigger and they will just cover up the slot next to the PCIE X 16.
