MSI MEG Ai1000P & Ai1300P power supply support PCIe5.0/ATX 3.0

by ·

It has been reported before that MSI’s next-generation MEG and MPG series power supplies will soon support the PCIe 5.0 power supply standard and provide corresponding interfaces and connecting cables. Leaked information shows that MSI plans to launch two new MEG series power supplies this year, as well as three MPG series power supplies.

Recently, Twitter user @g01d3nm4ng0 has exposed the slide of the two power supplies of MSI MEG Ai1000P (rated power 1000W) and MEG Ai1300P (rated power 1300W). It is shown that these power supplies will be based on the new MSI GI engine, which has obtained 80 PLUS platinum certification, and not only supports the PCIe 5.0 power supply standard but is also compatible with ATX 3.0. This means that the new power supply can withstand twice the total power load peak or three times the GPU power load peak at intervals between 1 and 10 milliseconds.

MEG Ai1000P and MEG Ai1300P power supplies provide a 12+4Pin PCIe 5.0 external power supply interface. It can fully meet the 12VHPWR High Power Connector (H+) standard of PCI-SIG, and the rated power can reach 600W. However, there is only one PCIe 5.0 external power supply interface, and there is no configuration of dual PCIe 5.0 external power supply interfaces.

MSI also offers an interesting feature on the MEG Ai1000P and MEG Ai1300P power supplies, where users can monitor various operating parameters of the power supplies using the Gamer Intelligence app. Power is connected via USB 2.0 (internal header), allowing applications to read data on load, real-time power, fan speed, etc. at various voltages.


It’s unclear when MSI will launch these power supplies or what their pricing will be. As early as the second-generation ROG Thor series power supply launched at the end of last year, ASUS has taken the lead in supporting the new PCIe 5.0 external power supply interface and provided the corresponding connection cable. In contrast, the progress of most power supply manufacturers is relatively slow.
