12VHPWR and its revision 12V-2x6 (H++) are modern PCIe power connector standards published by the PCI-SIG that aim to deliver more power to PCIe devices such as GPUs but in a smaller foorprint than the older PCIe 6- and 8-pin connectors.[citation needed] Since 12VHPWR's debut on Nvidia's RTX 40-series GPUs,[1] the connector's been infamous for its design flaws that make it quite prone to ignition.[1][2] The minor revision 12V-2x6 aimed to mitigate these issues but ultimately succumbed to it's predecessor's shortcomings.[1] As of July 2025, there are still reports of the connectors catching on fire even when using accessories that advertise less risk of catching ablaze.[citation needed]
Background
An early iteration of the connector without the sense pins first appeared on PCI-SIG member Nvidia's RTX 3090 Founders Edition (FE) graphics cards. Since then Nvidia has used the connector on some of their RTX 40 Series GPUs and all RTX 50 Series GPUs.
