GinTai 8(pin) to 8(pin) Power Supply Cable Replacement for DELL R730 and Nvidia K80/ M40/ M60/ P40/ P100 PCIE GPU（35cm）

Installed this in my R730XD to power a P100 card. Important to not that mine did not come with a tag or stripe on the end, and I had to research which end was which. It is possible to reverse the cable, which would send 12v to ground and short the 12v rail. This could potentially damage equipment. This design flaw is not the fault of the manufacturer, but they could have mitigated the risk by labeling the ends with a sticker, similar to how Dell labels it's stock cables, and possibly including an info card in the box, rather than a lens cleaning cloth.

I originally gave this 1 star -- because I had the cable plugged in backwards. The internet will make you think the Dell riser port is EPS-12V. It is not! It is a PCI-e power layout, but it's keyed the same as EPS-12V. Plug the end with 3 yellow wires into the Dell riser. The end with 4 yellow wires goes into your GPU.

Poorly made, lose connector and wire started sparking on first install. The little metal bit is the connector pin inside the cable plug, it was in my GPU when I removed the cable. Scary, to hear and see sparks inside your server. Also the cable ends are not labeled, nor are they keyed with a wider clip for the server side. Both clips are narrow with no indication of cable orientation.

Cable works perfectly. Before purchasing I read the reviews about cable direction and had no issues getting the cable to work. At first Unraid wouldn’t see the K80 but looked and the syslog and it was because you have to downgrade the NVIDIA drivers to 470.x.x

This cable worked perfectly in powering a Tesla P40 in a Dell R730 server. Also, the price is reasonable compared to other options. The reason for only 4 stars is that there is no marking for which end connects to the riser and which end to the GPU. It is important to get this correct, lest one short the computer's +12 supply. The correct connection is to plug the end with only three yellow wires into the riser connector. Note that the cable should route _under_ the GPU.

Worked in my R730xd with a tesla p40. Since both ends use the same connector keying, but have different pin-outs, make sure you double check the direction of the cable (which end connects to card vs riser)! If it's backwards, the system will refuse to boot, and both power supplies will flash orange.

I couldnt find these cables in amazon uk, but they was available via amazon.com in the US. As I really wanted well fabricated cables for the amount of wattage / amps drawn from the main board and riser, I was happy I could purchase these and have to wait a while for them to arrive. I was amazed at how quickly these cables arrived, less than a week, from US to UK and they was of excellent quality. As I know other people will be building GPU Servers using NVIDIA cards, it makes me wonder why these excellent cables aren't for sale via the UK site, but that said, its worth a little wait to get these great cables from the US and know my GPU/Motherboard will not be damaged by poorly made cables.

I ordered from the seller because it could be delivered fast. This was an absolute waste of time. 2 out of 3 cables didn't work. The cables look sturdy, however they are non functional. I got another set from eBay, it took a while but eventually they arrived and they worked. I cannot recommend this seller. It has serious quality control issues.

Lacks any form of label to tell which side to connect to which part..... how hard is it to add a tag or a few letters to each end?
