Topic: Powered GPU riser cable for GPU that supports monitor to rig? (Read 521 times)

Thank you everyone for letting me know. Especially from first hand experience.

So long as you are actually using POWERED x1 to x16 risers for the connection directly to your cards, it should not matter whether or not the splitter card has supplementary power or not. The x1 slot on the motherboard should be able to provide more than enough power for the card itself.

I personally have the Ubit one (with the 4x riser kit) and it works fine with my MSI 970a-g43. I'm running a total of 6 1060s (3GB) on this rig.

Note that there's no guarantee your motherboard will work with those splitters. Some have reported getting all 4 to work (like I have), but others have hit a limit below the number of physical slots they end up with. Just know that your mileage may vary, and have a plan ready.

No need to do that. I suppose you have at least 2 risers PCIEX1 to PCIEX16 to use with your PCIEX1 slots. You need another riser, a total of three to put three cards. Put a riser like the normal ones in the PCIEX16 slot, it's no problem , then you have space to use all other remaining PCIEX1 slots. Connect the card to the monitor through the DVI or HDMI directly from the card that is installed with an PCIEX1 riser in the PCIEX16 slot.

Do you use any PCI-e Express 1x to 4 Port splitters. If so, have you had better luck with powered vs non-powered?

Great input. for some reason I was under the impression that this type of riser could not be used on the dedicated GPU for display functionality. Thank you for clearing it up that it is not an issue. i am going to start out with three of these risers in each slot then use the 1 to 4 pci expansion slots and see how it goes.

Error from above  . The powered 4 in 1 PCI-E Riser Adapter Board (https://www.amazon.com/Cablecc-Express-Switch-Multiplier-Splitter/dp/B073QNW3L9/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504685701&sr=1-2&keywords=1+to+3+PCI+Express+1X+Slots+Riser+Card  ) only has a 4 pin power plug (not 6 pin), which I assume to be a molex. In that case I will be using the sata cable to power this. Wanted to correct this from above.

Would it be horrible if I plugged both a sata cable in and a molex cable in at the same time to power the  4 in 1 PCI-E Riser Adapter Board . is that a completely ignorant move? I assume so but appreciate knowing why at least.


 

I am using this kind of risers x16 to x1 https://www.amazon.com/Onvian-Mining-Dedicated-Graphics-Supply/dp/B01MU51491/ref=pd_sim_147_6?_encoding=UTF8&psc=1&refRID=863P3M3YTHMTG34STFK8
and I hooked monitor to one of the card witch is connected to this riser. Using PC for normal work without any poblem, if card is runing on x1.

I use it for basic things like web browsing, email, and the occasional c++ compiling. But not games, so nothing to GPU intensive. But i do notice that when i have more than one youtube tab open the hash rate can go down from 30 to 29, 28 sometimes and even 24 sometimes.

I think I am going with the Powered riser cable: https://www.amazon.com/gp/product/B01NAE4O7I/ref=ox_sc_act_title_1?smid=AFM4QEJU7QLZR&psc=1


a few other questions if I may. Is it a bad idea to want to get 8 GPU's on a three PCI slot motherboard? If I use powered risers for each of them and a powered 4 in 1 PCI-E Riser Adapter Board. is that really that bad of an idea?


Which 4 in 1 PCI-E Riser Adapter Board would be better. I assume powered but never hurts to ask as I realize I have much to learn.

The non-powered 4 in 1 PCI-E Riser Adapter Board. Has excellent reveiws. Again, it is not powered but the risers i use will be powered: https://www.amazon.com/gp/product/B073W9KCFC/ref=ox_sc_act_title_8?smid=A3JV1FMRJ9GCIF&psc=1

Here is a powered 4 in 1 PCI-E Riser Adapter Board. Wouldn't this be a better alternative than its non-powered counterpart. It bothers me a bit that all the data from the 4 pci slots is going through 1 usb cable but I assume it should not be an issue. I will use the 6 pin power plug on this  and plug straight into the power supply: https://www.amazon.com/Cablecc-Express-Switch-Multiplier-Splitter/dp/B073QNW3L9/ref=sr_1_2?s=electronics&ie=UTF8&qid=1504685701&sr=1-2&keywords=1+to+3+PCI+Express+1X+Slots+Riser+Card 


Thanks, look forwarding to maxing out my motherboard.

Is this system a dedicated mining rig, or do you wish to use one of your cards for gaming at some times? If the latter is true, then an x16 to x16 riser would be better for you than an x1 to x16 riser. If it's a dedicated mining rig, then a powered x1 to x16 riser is fine.

An unpowered x16 to x16 ribbon riser should be fine, especially if you're only going to have one unpowered riser on your motherboard. (More than that, and you could start having issues.)

I have not seen evidence that a working powered riser has shortened the lifetime of a graphics card.

Overall, you should be fine connecting your monitor to the graphics card connected to the primary x16 slot (the physical x16 slot closest to the CPU), regardless of whether that card uses a riser.

Hello,

I am at a basic bottleneck as to how to plug in my monitor to the rig. I have this motherboard: GIGABYTE GA-B250M-DS3H LGA1151

 My motherboard has a total of three PCI slots: 1 x PCI Express x16 slot (long)  2 x PCI Express x1 slots(short)

I am hoping to get fit more than three gpus on this motherboard but in order to do this. I need a cable riser for the 1 x  PCI Express x16 slot. Because the GPU covers up both of risers or one other riser depending on which gpu i install. I will also be plugging my monitor into the the GPU that utilizes this slot x16 slot. 

Which cable riser is better for a gpu that will be pushing signal to my monitor. Powered vs non-powered riser cable:

A.) Powered riser cable: https://www.amazon.com/gp/product/B01NAE4O7I/ref=ox_sc_act_title_1?smid=AFM4QEJU7QLZR&psc=1


B.) Non-powered riser cable: https://www.amazon.com/EZDIY-Express-Flexible-Extension-Card-25cm/dp/B01NH0GW7Z/ref=sr_1_3?s=electronics&ie=UTF8&qid=1504654154&sr=1-3&keywords=gpu+riser+cable


I have read that a powered riser cable is better. Because it allows for the GPU to act as if it were connected to the actual motherboard. and the capacitor gives it space as the voltage goes up and down. Is this the safest bet if I am going to be plugging my screen into this GPU. Will this riser shorten the life of my GPU? Are there any better alternatives.

Any input on this is appreciated. I am definitely not an electronics engineer but know a little about voltage and i think the power riser would be better with the capacitor.

Has anyone else tried this or had any experience with plugging there monitor directly into one of the GPU's on there rig?
