MSI MEG Ai1600T PCIE5 ATX 3.1 Fully Modular SMPS

The MSI MEG Ai1600T PCIE5 is a 1600-watt fully modular ATX 3.1 power supply engineered for demanding desktop builds, including high-end gaming rigs, AI workstations, and multi-GPU compute platforms. Holding an 80 Plus Titanium certification, it achieves up to 94% efficiency under typical loads, meaning less energy is wasted as heat and your electricity costs stay lower over time. At the heart of the MEG Ai1600T is a full digital design architecture driven by an MCU that actively manages the interleaved Power Factor Correction circuit and LLC resonant topology. This approach delivers tighter voltage regulation and more dynamic load response compared with traditional analogue designs. The interleaved PFC section uses SiC (Silicon Carbide) MOSFETs — a server-grade material choice — which reduces switching losses, improves thermal management, and supports the unit's wide 100–240 V universal input range. The connector array is generous and future-ready. Two native 12V-2x6 (PCIe 5.1) connectors each support up to 600 W, making the unit a solid foundation for the most power-hungry GPUs available today. Nine PCIe 6+2-pin connectors, two EPS 4+4-pin connectors, a single ATX 24-pin, eight SATA, and eight peripheral 4-pin connectors round out the lineup. The 12V-2x6 cables feature a distinctive yellow connector colour for easy visual confirmation of a fully seated connection. A 135 mm fan with a double ball bearing keeps the internals cool while extending the fan's operational lifespan relative to sleeve-bearing alternatives. All capacitors are Japanese-made, rated at 105°C, supporting long-term reliability. The fully modular cable system uses soft-braided sleeving for improved cable management, and a pre-installed cable organiser makes routing even more convenient. MSI Gaming Intelligence software integration via a USB Type-C connection enables monitoring and adjustable settings directly from your desktop. The unit can sustain a 3840 W power excursion (up to 240% of rated output) for 100 µs, meeting Intel ATX 3.1 PSDG compliance for GPU transient spikes. A comprehensive protection suite covers OCP, OTP, OPP, SCP, OVP, UVP, SIP, and NLO conditions.
