User Reports 12VHPWR Connector Melting From the PSU Side (Updated)
This time it's not the end on the GPU that has the issue.

A Reddit user reports that their BeQuiet Dark Power 13 1000W power supply has succumbed to the same 12VHPWR melting catastrophe as some RTX 4090s. The user revealed a picture of the 16-pin supported power supply, showing a fully melted connector on the power supply side. This suggests the possibility that there are still serious reliability issues that need to be ironed out with the new connector.
Melting 16-pin connectors aren't anything new, especially on more power-hungry graphics cards like the RTX 4090. However, seeing a melted connector on the power supply is almost unheard of. This is especially true considering there were no adapters being used, since the Dark Power 13 features native support for 16-pin cables.

Images show that the bottom row of pins on the connector itself (right next to the four 'sense' pins) was completely destroyed in the melting process making them barely recognizable compared to the upper row of unscathed pins. Likewise, the 16-pin power connector housed inside the PSU showed similar damage, revealing melted plastic along the bottom row of ports.
However, this is one case of a 16-pin power connector burning up on the power supply end and should be taken with a grain of salt. Without multiple reports, it's impossible to discern how widespread the issue could be or if this is a one-off.
"“This is a unique case and we already have reached out to the customer to learn more," Be Quiet told Tom's Hardware in a statement. "As our brand is known for highest quality standards, we treat this seriously and have initiated an investigation." The company added that customers should contact the company directly if it sees any issues.
Echoes the series of RTX 4090 melting reports that have come up over the past year. Even though these reports do not surround damage on the power supply end, it's technically possible for the same damage to occur on both ends, since the GPU connector and power supply connector are the same. If this report is legitimate it could be the start of a new wave of 16-pin disasters as more people continue to adopt Gen 3 power supplies.
Tom's Hardware has reached out to Nvidia, as well. An Nvidia spokesperson said we may not hear back for a few days due to a company closure.
This issue couldn't have come at a worse time with more RTX 4090 16-pin connector melting reports still coming in. Nvidia claims that all of the 16-pin issues are related to user error, with the connector not being seated properly. But it's hard to believe that all of the errors were due to user error since some of these latest reports come from people who claim to be veteran system builders.
Hopefully, this power supply issue with the 16-pin power connector does not extend to more users. But if it does, this could become an even more serious problem for the graphics card and power supply industries.

InvalidError But it's hard to believe that all of the errors were due to user error since some of these latest reports come from people who claim to be veteran system builders.
Even rocket scientists and engineers make mistakes. Just because a connector may have been plugged in correctly initially doesn't mean it didn't pull out during cable management, other not necessarily related internal work or transport/shipping. -
atomicWAR I'll bet they didn't have it fully inserted but it may be it is actually one of the few legit faulty connectors/connections. Could be the wire itself or on the PSU side if that is the case.Reply -
hotaru251 I don't see this being "user error" given its entire bottom row & unlike GPU the clip on psu side is a lot more reliable.Reply
even IF its user error..the amount of times "user error" happens should be a red flag to re-design the connector. -

How many out of how many?hotaru251 said:even IF its user error..the amount of times "user error" happens should be a red flag to re-design the connector.
Nothing will get done about it if the field failure rate is something like 0.1% - that is considered very low by consumer electronics standards. If you are hoping for a safety recall, 94V-0 plastics cannot sustain a flame, so you aren't going to get a recall for that unless you can show standard-compliant cables being set on fire despite the standard calling for materials that should make it impossible. -

I can still see it being user error BUT it does seem a little prone to these issues for users. In a hopefully near future revision shortening the sensing wires, making the connector tab have a louder clip and doing like MSI did and coloring the connector would be solid first steps in fixing the problem I believe.hotaru251 said:I don't see this being "user error" given its entire bottom row & unlike GPU the clip on psu side is a lot more reliable.

The real solid first step towards fixing the issue would be to have actual remote voltage sense pins to detect total connector+cable drop so the GPU can throttle to keep total wiring losses within specs and give a warning when the connection becomes excessively bad. Ex.: if wiring losses are set to 10W max, that would allow up to 200mV of wiring droop at 50A. If the cable has 300mV of droop, then the GPU throttles down to 33A to keep total wiring losses under 10W. Even if you end up with 5W of losses concentrated on a single pin, the power/ground plane the pin connect to should be able to dissipate that without burning out the connector.atomicWAR said:I can still see it being user error BUT it does seem a little prone to these issues for users.

PlaneInTheSky ---- -----, can we stop blaming the usersReply
this is like Apple "you're holding it wrong" all over again
imagine regular house sockets consistently melting cables and settings people's house on fire, and the community going "user error, you didn't plug in the cable correctly", stop with the damn excuses, this is 100% the fault of the people who designed this
MOD EDIT: Profanity Removed -
So now this becomes a BIG news topic, just because some random guy on REDDIT posted his findings (aka only 1 user), and that too this is an isolated case, since nobody else has companied about this issue on the PSU side? Hmmm, Great ! Keep them coming !Reply
