Wireview 2 is a great product. As usual for Thermal Grizzly. It won't work with my card, though, as the socket is too deep.

I'll probably get one of the new PSUs when they are released, that have protection. 

Meanwhile, when I've built the system, I'll keep an eye on it with my laser thermometer.

Agree completely. I’ve had mine installed for about 10 days, yesterday the desktop app was released (had a beta version before that).

I never had any indication of connector pin imbalance problems, but I’ve always been a bit of a gadget freak so there you go 🙂

Sadly, no good for my card as the connector on the card is too recessed. 

I use Wireview 1 since I have this bloody 12VHPWR connection in my rig. Or lets be precise: first, I used the cablemod 180° connector, but this was called back and they did a mess so I did not get their v2 but a refund instead and bought Wireview. Version 1 has no active control of the pins, but the connection is so firm and results in no bending at all that I am confident with my connection now. 

Besides this I throttled down my 4090 to 0.950V (resulting in no loss of performance) and in MSFS2024, the card never goes above 280W, so it is anyway extremely unlikely that something melts. 

My system is built now. I have a qulaity laser infrared thermometer and a clamp meter, so I'll  check it from time to time. 

From time to time is waaaaay to slow/rare. If one of the pins has an issue, your plug will melt down within seconds or minutes max, your infrared thermometer and clamp meter will serve you nothing. No need for a "quality laser infrared thermometer" if you can smell the molten plastic or even see the smoke 😁

It's possible for it to come catastrophically loose suddenly... but not usually, it doesn't have to be a case of no catastrophic resistance or catastrophic resistance, in an instant, like a swatch. Depends on the degree of increased resistance. 65C to 75C isn't uncommon for the 12V-2x6 connector under load. The resistance is likely to gradually increase over time as the contact with the pin gradually becomes looser over time. Thus, any increase above 65C prewarns of an impending issue.

Yes, a 12VHPWR (or the newer 12V-2x6) connector often gets progressively warmer over time if a failure is developing. Because these connectors handle massive power, a minor issue—such as a slightly loose connection, poor pin contact, or a sharp bend—creates resistance. 

This increased resistance generates heat, which causes further oxidation and deformation, creating a "vicious cycle" of increasing heat until the plastic melts or the GPU fails. 

 

 

 

I already own an infrared laser thermometer and a clamp meter... so until the new PSU's arrive that monitor the connector it's the only option. 

My card is a 5080, too, not a 5090, so less power draw.
