MSI is joining the ranks of power supply manufacturers that are adopting the latest PCIe Gen 5 12+4 pin (12VHPWR) power connector. It has previously been seen on the forthcoming ASUS Loki PSU, and newly revealed photographs show it will be included on select upcoming power supply models.

The photographs show the 12VHPWR connector will be included on select MEG and MPG power supplies. Wccftech has confirmed an upcoming lineup of these that will fully support the new standard. At the top of the lineup is the MSI MEG series with up to 1,300 watts of power. They will also feature the new G.I. Engine, which is said to help manage power-hungry GPU and CPU combinations. The new feature seems to support an earlier theory by Igor Wallosek that the extra pins with the 12VHPWR standard would allow monitoring of power usage of the GPU. The MPG lineup is being updated to V2, and only those will feature the new connector. They will offer up to 850 watts of power.

  • MSI MEG 1300W 80 Plus Platinum – Including G.I. Engine
  • MSI MEG 1000W 80 Plus Platinum – Including G.I. Engine
  • MSI MPG 1000W 80 Plus Gold
  • MSI MPG 850W 80 Plus Gold
  • MSI MPG 750W 80 Plus Gold

MSI is including two cables to cover nearly all the bases. There is one cable with the 12+4 pin configuration on each end. Owners of Founders Editions will be able to enjoy all the features and simplicity of using a single cable. Additionally, there is a 12+4 to dual 8-pin cable. The 12VHPWR standard supports up to 600 watts of power delivery, which is enough for the current NVIDIA GeForce RTX 30 Series cards, although AIB cards with 3x 8-pin connectors will still need the third to connect separately. A new product description from cable and connector manufacturer Amphenol ICC explains the new standard in greater detail.

Amphenol ICC introduces the Gen 5, Minitek® Pwr PCIe® connector system. This new introduction CEM 5.0 PCI Express® 12VHPWR auxiliary hybrid connector and cable assembly support the 600W GPU cards. The 12VHPWR connector is not designed to mate with legacy PCI Express® 2×3 and 2×4 12V Auxiliary Power connectors. The 12VHPWR connector power pins have a 3.00mm pitch, while the contacts in a legacy 2×3 and 2×4 connector lie on a larger 4.20mm pitch. New PCIe® Connector System (CEM5) is designed for power applications with current rating upto 9.5A/pin (12 pins energized) and the 4 signal pins supporting signal transmission.

• Rated current up to 9.5A per contact with all 12 power contacts and 4 Signal contacts
• Fully isolated terminals
• Positive locking on housing with low thumb latch operation
• Low level contact resistance: 6mΩ max.

The new MEG and MPG models are expected to launch sometime in 2022.

As a child of the 70’s I was part of the many who became enthralled by the video arcade invasion of the 1980’s. Saving money from various odd jobs I purchased my first computer from a friend of my dad, a used Atari 400, around 1982. Eventually it would end up being a lifelong passion of upgrading and modifying equipment that, of course, led into a career in IT support.
