Ready for ATX 3.1 and PCIe 5.1 builds

The MSI MEG Ai1300P PCIE5 is a fully modular 1300 W ATX power supply built for high-end gaming systems. It delivers up to 92 % efficiency under the 80 PLUS Platinum programme and uses 100 % Japanese 105 °C capacitors. A native 16-pin 12V-2x6 cable supports modern graphics cards without adapters.

Verify case length and cable routing

Confirm your chassis can accommodate a 150 mm deep unit and plan cable paths for the sleeved 24-pin, two EPS, six 6+2-pin PCIe and one 16-pin PCIe connectors. The unit requires a 100–240 V, 50/60 Hz mains supply and provides 16 SATA power plugs for drives and peripherals. A mini-USB link enables software monitoring with a compatible motherboard.

Sustained output with hydro-dynamic cooling

The single +12 V rail maintains stable voltage during extended loads while the hydro-dynamic bearing fan meets Cybenetics Standard ++ acoustic limits. Industrial-grade OCP, OVP, OPP, OTP, SCP and UVP circuits protect components through long sessions. DC-DC module design keeps regulation tight when the system draws continuous power.

Questions about this item

What cables come with the MSI MEG Ai1300P PCIE5 and what must I buy separately?

The box includes a 24-pin ATX sleeved cable, two EPS cables (8-pin to 4+4-pin and 8-pin to 8-pin), six PCIe 6+2-pin sleeved cables, and a native 16-pin PCIe 5.1 cable. No extra cables are required for standard builds.

How do I choose between the available connectors for my GPU?

Use the single 16-pin 12V-2x6 cable for modern PCIe 5.1 graphics cards, or use the six 6+2-pin PCIe cables for older GPUs. Both connector types are included and fully modular.

What does the 1300 W rating mean when the unit is installed in a PC?

The unit can deliver 1300 W continuously with up to 92 % efficiency at 80 PLUS Platinum levels, handles 2x total power excursions and 3x GPU excursions per ATX 3.1, and runs quietly under Cybenetics Standard ++ noise certification.
