The PCI-SIG organization has not yet fully adopted the new PCIe 12V 2×6 power connector standard, which is intended to replace the 12VHPWR connector. Nevertheless, FSP recently introduced the first power supplies equipped with a 12V 2×6 connector at an event in South Korea, Quasarzone reports. The manufacturer also provided further information about the new connector.

FSP will release three power supplies with the new 12V 2×6 connector: the flagship model Hydro PTM in Mini-ITX format. There are several obvious visual differences between the 12VHPWR connector and the new 12V 2×6, such as: B. new connector markings, a larger pin socket depth (from 4.2 mm to 4.45 mm) and a larger auxiliary signal pin socket size (from 1). 6 × 9.3mm to 1.70 × 9.4mm).

The new 12V 2×6 connector also features a shorter signal pin length (from 4 to 2.5 mm). This prevents incorrect connection of the power cable connector to the power outlet, otherwise the power supply will not enter high performance mode, thus preventing possible overheating and melting of the graphics card power connector under load.

When developing a new PCIe power connector, PCI-SIG was faced with the task of eliminating the main disadvantage of the original 12VHPWR – poor contact due to insufficient pressure of the connector on the connector. It should be noted that this issue has been resolved on the new 12V-2×6. At the same time, other connector specifications were also changed. According to FSP, the new 12V-2×6 has the following features:
- Rated current of at least 9.2 A per contact with all 12 contacts active and the temperature limit is 30 degrees Celsius above ambient at 12 VDC;
- the effective value of the current should not exceed 55 A in one direction or another;
- Power cables and contacts must meet specified current and temperature limits;
- The connector must withstand a tensile force of at least 45 N.
The corresponding software also needs to be updated. According to Quasarzone, FSP plans to release power supply models with the new 12V 2×6 power connector in mid-October. However, their costs are still unknown.
