I have a suspition, that not all cables and connectors are made with the care they deserve, and there are some substandard and even dangerous cables out there. This survey should help to identify them.

Post your photos of 12 pin GPU connectors, write identification data about the product, when you bought it, current measurement results on all 6 live wires, try to estimate, how much used the cable was before you made the pictures and measurement, describe the state of the connectors. In case you have a some additional information, post it as well, as thermal imaging shots, etc.

Post information even if you do not have e.g. current measurement, if you do not know the exact number of insertions (just estimate it). Even he information, that the cables feel the same warm in the hand is sufficient.

Please crop and resize the photos to a sane size (for example 1600 pix long side) and insert them into your message as a thumbnail. Good free photo tool is Faststone.

A template:

Cable manufacturer and model, connector type:

Date of purchase, manufacture, serial number:

Number of insertions on PSU side:

Number of insertions on GPU side:

Installation type:
Fixed cable in a PC, handled the cable a lot on a test bench, etc.

Current measurement: Include information on how long has the plug been undisturbed before the measurement, try to move the cables as little s possible to avoid any changes in the plug during the measurement (for example rubbing off corrosion on the contact area).

Connectors and socket state description: Include info about the movement of metal connector pieces in the plastic plug body.

Issues:

Photos:
Describe what end of the cable you photographed, phoptograph the GPU socket too in case of some damage. Try to photograph the plug in such angle, that the width of the slots in the metal connection pieces is visible to assess if the connector tubes are not opened too much.

Do not strip EXIF info from your photos to somehow support credibility of your photos.

I will kick it off:

Cable manufacturer and model, connector type: Cable supplied with Seasonic Vertex GX-1000

Date of purchase, manufacture, serial number: 11/2024, ?, R2309SA109121823

Number of insertions on PSU side: 1

Number of insertions on GPU side: 4

Installation type: Fixed cable in a PC

Current measurement: 10 days after insertion, RTX 5080 - 400W load with Furmark, total current 33,4A, Current in individual wires 5,6 – 5,8A

Connectors and socket state description:
No damage
Plastic plug bodies feel pretty soft.
Metal connection pieces move in the plug body a bit, the range of movement is visible in the photo
The metal connector tubes have one slot in them.

Issues: none

Photos:

GPU side (PSU side is the same):

Comments:

These plugs obviously work well at this moment, but they do not feel too sturdy. I would be careful about abusing these plugs with too many insertions. According to the serial number, production date of this PSU may be September 2023. I believe that plugs supplied with freshly made PSUs may be better than plugs supplied with this PSU.

I used just a crappy macro camera on my cheap mobile phone, but you can see the details and width of the slots in the contact tubes pretty well in my photo. I do not see much in your honestly...
I cropped it all to hell in this low light, super early here on the tundra.

Edit:

And I had a relapse and picked my nails.. dammit.

Connectors and socket state description:
No damage.
Plastic plug body feels firm.
Cables are molded in plastic and I cannot pull/push on them to see if the metal connector tubes move

Issues: none

GPU end:

Comments:

This plug feels much more solid and tight than the previous plug. The metal connector tubes inside are a different type, they have two slots in them and both sides are closed together.

This cable has more robust connection with PSU - two six pin connections in bodies of two 8 pin plugs. I will use this instead of the original cable with two 12 pin plugs on both ends.
