Intel has added a new 12+4-pin 12VHPWR power connector to its Data Center GPU Max 1100 accelerators in the form of PCI Express expansion cards. The manufacturer followed the example of NVIDIA, which equipped the graphics cards of the older GeForce RTX 40 series with this connector.
The so-called PCIe 5.0 power connector, more commonly referred to as a 12VHPWR or as a 12+4 pin connector, is not a technical requirement for power supplies that claim to be ATX 3.0 compliant. However, all previously presented power supply models of the specified standard are equipped with at least one such connector.
NVIDIA is the first company to introduce a new power connector for its next-generation gaming graphics cards. The connector allows you to replace up to four traditional 8-pin PCIe connectors and can transfer up to 600W of power.
Use of the 12VHPWR connector will remain exclusive to NVIDIA graphics cards until January 2023. At that time, Intel was planning to launch the server graphics accelerator Data Center GPU Max 1100. When it comes to gaming graphics cards, neither AMD with its Radeon RX 7000 graphics series nor Intel with its Arc Alchemist accelerators have opted for the new performance standard and use them usual 8-pin connectors.
We also add that 12VHPWR has presented GeForce RTX 4090 users with a number of issues – some have had these connectors melted. So far, it is not known what exactly is the cause of the problem and various theories have been put forward. Perhaps the problem lies in inferior complete adapters from four 8-pin to one 12+4-pin connector. Another theory is that users are to blame for not fully inserting the plug into the connector. Let’s hope Intel accelerators don’t repeat the fate of some GeForce RTX 4090s.
