MSI Preps 1300W power supply with PCIe 5.0 power connector

According to a new report from Wccftech, MSI is working on the company’s next-generation MEG and MPG series of power supplies. Additionally, the new units will arrive with the new PCIe 5.0 power connector to power the next wave of top graphics cards.

The MEG series, the flagship line, will debut with capacities between 1000W and 1300W. The power supplies carry 80 Plus Platinum certification and use MSI’s GI engine, although we don’t know what this latest feature brings to the table. On the other hand, the MPG series will be available in 750W, 850W and 1000W capacities. These come with 80 Plus Gold certification and lack the GI motor.

Despite the model and capacity, MSI’s upcoming power supplies offer the PCIe 5.0 CEM (12VHPWR) power connector. It delivers up to 600W of power, 150W more than Nvidia’s 12-pin PCIe power connector that wasn’t taken out of the chipmaker’s Ampere Founders Edition graphics cards. The 12VHPWR connector has 12 power contacts and four signal contacts. Unfortunately, there is no information on whether signal contacts are optional or not.

The 12VHPWR power connector allows manufacturers to simplify their designs on power-hungry graphics cards and, at the same time, significantly reduces cable clutter for the consumer. For example, a single 12VHPWR power connector can replace three 8-pin PCIe power connectors typically found on high-end and overclocking-oriented graphics cards.

Early rumors claimed that Nvidia’s GeForce RTX 3090 Ti would be the first graphics card to arrive with the PCIe 5.0 power connector. Since Nvidia has yet to release the Ampere graphics card, it’s impossible to confirm if the rumor is true. The GeForce RTX 3090 Ti Suprim X 24G, which was sold out at $5,500, is said to have a TDP of 480W and requires a 1000W power supply. However, MSI seems stuck with a PCIe power connector configuration three-pin.

The price of MEG and MPG power supplies is unknown. However, Wccftech’s sources claim that MSI will release the new units by Q2, just in time to power the upcoming PCIe 5.0 compatible graphics cards.
