The problem is not the 12VHPWR connection as such, nor the repeated plugging or unplugging.
Standard compliant power supply cables from brand manufacturers are NOT affected by this so far.
The current trigger is NVIDIA’s own adapter to 4x 8-pin in the accessories, whose inferior quality can lead to failures and has already caused damage in single cases.
Splitting each of the four 14AWG leads onto each of the 6 pins in the 12VHPWR connector of the adapter by soldering them onto bridges that are much too thin is dangerous because the ends of the leads can break off at the solder joint (e.g., when kinked or bent several times).
Bending or kinking the wires directly at the connector of the adapter puts too much pressure on the solder joints and bridges, so that they can break off.
The inner bridge between the pins is too thin (resulting cross section) to compensate the current flow on two or three instead of four connected 12V lines.
NVIDIA has already been informed in advance and the data and pictures were also provided by be quiet! directly to the R&D department.

不是有原生16PIN也烧毁的案例吗?

所以现在的这一堆转接线怎么办,召回吗

nv怕不是省成本省出魔怔了吧,这点都能抠

结论就是 别用带NV标的 8PIN*4的12VHPWR。
我3090TI 功耗比4090更高, 8PIN*3的12VHPWR 弯折90度 拔插那 ...

那个也是NV出的,而且这代4090丐给的就是这个一转三,也没烧卡

所以英伟达切换转接线方案时没做好QC?
那也很奇怪啊。

这真是迷之操作,FE本体看着可一点都不省,吊打一众AIC的非旗舰卡不算夸张,弄了转接线做工稀烂还出事故了 ...

竟然用焊盘而不是压接,简直离谱。。。一次的大线都是压接吧,那可是上千安的电流。
kaiwenwu 发表于 2022-10-27 14:50
是太粗了,压接只能16awg。这个转接头是14awg
raiya 发表于 2022-10-27 14:27
这个垃圾设计本身就有问题。
电热效应里面 ,电流是2次方关系。也就是说缩减线路数量,加大电流,明显会加 ...
moveable 发表于 2022-10-27 14:39
这也太差了,线居然不是压在段子里
momo77989724 发表于 2022-10-27 13:20
会直接不送 你们自己买去。。。
nekotheo 发表于 2022-10-26 22:52
会不会是老黄那帮人觉得自己牌面大就压供应商的价
然后供应商被迫降价索性降低成本保利润? ...
