MSI MEG Ai 1300P 1300W 80 + Platinum ATX 3.0 Power Supply

The MSI MEG Ai1300P is a 1300-watt fully modular power supply built around the ATX 3.0 specification, designed to meet the demanding power delivery requirements of high-end gaming and workstation builds. Compliance with Intel's Power Supply Design Guide (PSDG) ATX 3.0 means it can handle up to 2× total power excursion and up to 3× GPU power excursion, absorbing the sharp transient spikes that modern discrete graphics cards produce. A native PCIe 5.0 16-pin connector delivers up to 600 W to compatible graphics cards, including NVIDIA GeForce RTX 40 Series, without the need for an adapter harness. For builds using older hardware, eight PCIe 6+2-pin connectors are included alongside 16 SATA ports, four MOLEX connectors, and one FDD header, making the unit suitable for multi-drive or multi-GPU configurations. The MEG Ai1300P carries an 80 PLUS Platinum efficiency rating, reaching up to 92% efficiency under typical load, which reduces heat generation and lowers operating costs over the unit's lifespan. Power factor correction is handled by an Active PFC circuit, while the LLC Half-Bridge topology combined with a DC-DC module delivers stable, clean power rails. All internal capacitors are Japanese-made, rated to 105°C for extended thermal tolerance. A 120 mm fan with Hydro Dynamic Bearing manages thermals quietly and with reduced wear over long service periods. The unit's compact 160 × 150 × 86 mm footprint fits the majority of ATX mid-tower and full-tower cases, easing cable routing. Triple-layer sleeved cables enhance flexibility and durability during installation. Six layers of hardware protection — OVP, OCP, OPP, OTP, SCP, and UVP — safeguard connected components from voltage, current, and thermal faults. Integration with MSI Center software allows monitoring and synchronization within a wider MSI ecosystem.
