Wrong, Steve states that he believe what Ignor found is part of the problem but doesn't believe it's "the problem". Therefore nothing is disproven only unconfirmed.
There are a dozen British, EN and ISO standards on cabling and they all agree on one thing: No soldered connections without strain relief.

How would I know? If I had to guess it was to show cable routing to indicate how much strain it had on it.why put it back in after to take a pic? shows what? just doesn't want to admit user error.
if it were true they would state it in the original post also
been using it fine for over 2 weeks , almost 3
12VHPWR is a 600w connector which ideally you'd have natively from the PSU. In lieu of that you use the adapter with three or four 150w PCIe 8 pin connectors (for 450w or 600w cards).
PCIE 8pin has 2 sense cable and the load is distributed into 3 sets of +12V wires. below is the pinout for PCIE 8pin. max power rating for PCIE 8pin cable is 288W meaning each cable carries 8A current.
the new connector is 16PIN not 12PIN.@pc-guy and Surveyor. Thanks for the replies however, and obviously it's my fault for not explaining properly, you're both telling my stuff i already knew, so I'll try to make my question make more sense.
So a standard 8pin connector has 3 power pins (+&- for a total of 6) and 2x sense pins, when plugged into the adaptor each of those get reduced to single wires and when all four are plugged in you've basically got 4 power wires (+&- for a total of 8) and 4 sense wires. Essentially we connect each 8 pin PCIe connector to a single wire pair and then connect those 4 wire pairs (4x8 +&-) to 12 pins, so why not just connect those 4 wire pairs (plus the sense wires) to another 8pin PCIe connector with the sense wires connected to the sense connector.
E.g Using the lower image you posted from Igor, pc-guy, the yellow and grey boxes to the left of the 12pin have 4 wires going into them, one from each of the 4 x 8 pin PCIe connectors (and that's what the actual images show) so why not have a 8pin PCIe connector where those yellow and grey boxes are, why terminate 4 wire pairs (8 in total) on 12 pins, why not just terminate them on 8 pins.
This will happen naturally because the wires and connectors have non-zero resistance. There's even some negative feedback because copper has a positive temperature coefficient (hotter wires have more resistance, and so pass a smaller proportion of the current compared to their neighbours).
"Of course, today’s tests are only snapshots and the conclusion that you always look for a small edge somewhere to put on and insert may well be true in its statement. The design and manufacturing defects found on the plug, the drama during bending including the resulting mechanically damaged contacts are only one side. The error pattern as a whole is now far too complex to be able to determine 100% what the primary trigger was for whom and which adapter."Well Igor quickly changed his mind
Now he believes the problem is user error, people incorrectly connecting the cable
Cause simpler than thought? NVIDIA GeForce RTX 4090, the scorched 12VHPWR connector and how to plug it in | Blind Test | igor´sLAB
Sometimes you also have to listen to your children and do a blind test once. Apart from the fact that there are obviously three or four adapter types with different solder pads and cables…
