The MSI MPG A1250GS PCIE5 is a 1250W ATX 3.1 fully modular power supply built for elite gaming rigs and professional workstations running next-generation GPUs. Rated at 80 PLUS Gold efficiency and engineered to the ATX 3.1 specification, it handles the aggressive transient power spikes of RTX 40/50 series GPUs without voltage instability — a critical requirement for PCIe 5.0 GPU deployments. The native 12V-2×6 connector eliminates the need for daisy-chained adapters, providing clean, direct power delivery to high-TDP graphics cards.
The 135mm fluid dynamic bearing fan operates in zero RPM mode until thermal demand requires active cooling — keeping the system completely silent during light workloads. Flat, fully modular cables simplify cable routing in compact and show builds, while 100% Japanese capacitors ensure stable, long-term operation under sustained gaming and creative workloads. Backed by MSI’s 10-year warranty.
