MSI introduces MEG Ai1300P PCIE5, the first power supply with PCIe 5.0 and ATX 3.0 support

MSI has officially introduced the MEG Ai1300P PCIE5 power supply, the first power supply to comply with PCIe 5.0 and ATX 3.0 standards. This novelty has already been flashed in previous leaks, but as part of the official announcement, the manufacturer spoke about it in more detail.

As graphics accelerators become more “gluttonous” with each generation, the demands on the quality of power supplies also increase. According to MSI, the MEG Ai1300P PCIE5 meets the ATX 3.0 standard and all the necessary criteria for a high-quality power supply that can ensure stable operation of even the most powerful next-generation graphics cards.

The ATX 3.0 standard for existing power supplies was introduced by Intel. In short, the main differences of the standard are to ensure maximum reliability and higher efficiency compared to the standard ATX 2.0 power supply, as well as the ability to transfer up to 600 watts of power to the graphics subsystem if necessary.

In addition, the ATX 3.0 standard introduces a new PCIe 5.0 12VHPWR power connector, which differs from the usual 6 and 8-pin connectors by using a 16-pin connector (according to the 12 + 4 scheme).

Many current power supplies do not fully support the ATX 3.0 standard and therefore require the use of a special adapter that allows you to connect three to four regular 8-pin PCIe power cables to a new PCIe 5.0 12VHPWR connector. The MSI MEG Ai1300P PCIE5 power supply does not have this problem as it is equipped with a separate 12+4 pin PCIe 5.0 12VHPWR connector and a new PCIe 5.0 cable in addition to several conventional 8-pin PCIe connectors .

A PCIe 5.0 12VHPWR slot can deliver up to 600W of power to the graphics accelerator. However, regarding the PCI-SIG organization, MSI notes that modern graphics cards have an indicator for the maximum (short-term) power consumption, which can be three times higher than the declared TDP. This can become a serious problem with the current flagship accelerator GeForce RTX 3090 Ti, for example, or with future generations of graphics cards.

In a press release, MSI refers to rumors that NVIDIA’s next-generation flagship graphics cards can consume up to 600W of power. At the same time, according to MSI, power consumption in new generation accelerators can reach 1800 watts. As the manufacturer explains, these power surges usually don’t last longer than 100 microseconds, but they can put a lot of strain on the entire PC, especially if an insufficiently powerful and reliable power supply is used.

For MSI MEG Ai1300P PCIE5 power supplies, these peak power spikes are not a problem. With a rated output of 1300 W, the new product can withstand currents that are twice as high. The MSI MEG Ai1300P PCIE5 is stable at 120%, 160% and 180% over rated power and meets Intel’s ATX 3.0 requirements.


To fully comply with the ATX 3.0 standard, power supplies must also meet certain timing requirements. As shown in the table below, MSI MEG Ai1300P PCIE5 meets these requirements.

Unfortunately, the manufacturer has not specified when the MEG Ai1300P PCIE5 power supply will be available in stores. Nothing is known about the cost of new items either.
