COMeap GPU Power Cable for Dell PowerEdge R720 720XD R730, CPU 8 Pin Male to Dual 8 Pin(6+2) Male PCIe Power Adapter for NVIDIA Tesla GPU J30DG 15-inch(38cm)

4/2/2026 Update: I want to commend this company for excellent customer service, which is rare on Amazon. I previously left a review with concerns about incompatibility of the cables with the R730 / P40 (see below). The company reached out to me personally through Amazon and clarified that the "sense" pin (pin 6 on the riser side) is intentionally left empty. After receiving this info I plugged the cables in and sure enough, they work great. I've stress tested both cards and had no issues, temps max out at around 70C and the cables can deliver all of the power the cards need. They were also immediately recognized by the R730, I just had to install Nvidia drivers and everything worked smoothly. Just be sure to plug the side with the empty pin 6 into the riser side, and the other end of the cable into the GPU itself. OLD REVIEW: Going to try to save some others some headaches with this cable. This is NOT compatible with the R730 / Tesla P40 combo. The cables I got were actually pinned differently, but both cables had riser side pin 6 empty. This is a "sense" pin that is supposed to be jumped to riser pin 4. It is possible the cables might work if plugged in, but it is dangerous to use them since they have the wrong pinout. Another reviewer has shared the correct pinout below- it is possible to repin the cable but requires some technical knowledge. Also, this cable has no keying to prevent it from being plugged in backwards, which could cause a fire and destroy your server. For this reason it is very important to plug the cable in such that the plug with the 3 12V pins is on the riser side, and the plug with the 4 12V pins is on the GPU side. Buyer beware, this could be a dangerous cable if you do not know what you are doing.

lifesaver works perfect with the T420 poweredge

Well made. Fits in my Dell PowerEdge R730XD with Nvidia RTX3060 GPU. No issues for about 6 months installed.

Caused a "Voltage outside range." Error on my NVidia Tesla V100 and P40 cards when connected with my Dell R720. I bought these because they specifically stated they worked with Tesla Cards and the R720.

Work the way it should. Price okay. Thanks

Worked without any modification in my application. I have a Dell R730 power edge server and I installed a Tesla M60 card. The side missing one pin goes to the riser and the side with all eight pins occupied goes to the card.

Nicely made with quality PCIe power connectors, slipped on confidently, (I could feel the contact pressure due to the good fit of the plastic parts) Conductors exposed enough for pin out verification but plenty of nylon sheathing with shrink wrap to keep the extra length under control and lookin good… in the server where no one should be caring aboot that. But still…

Functionality: I was using this to hook a Nvidia Tesla P40 to a Dell Poweredge R730xd. I had just purchased the P40 and thought there was an issue with it. I was about to return it because the computer could see the card running: "root:~# lspci | grep -i nvidia 82:00.0 3D controller: NVIDIA Corporation GP102GL [Tesla P40] (rev a1)" but I found nothing running "root:~# nvidia-smi No devices were found" I tried multiple Nvidia drivers and tests with no luck. Finally I took a multimeter to the cable coming from the PCIe riser and found pin 6 that should have been 0v was reading -3.3v. I Googled it and the solution was that it was a sense pin that had been wired to ground. I spent way too long getting the pins out using tweezers and staples and swapping pins 4 and 6. As soon as I plugged the cable in with the wires swapped, the card was recognized right away. It took two days of troubleshooting to get this fixed. I should have started with the cable, but I was focused on the GPU and drivers.

Parfait pour une alimentation des Tesla k20xm

It works

it looks great but is kinda useless..

This did not worked on NVIDIA Tesla P40(24GB) and Dell R720. When I plug in the cable, the server refuses to even start up. Cables going back
