Power demanding builds with this 850W ATX 3.1 fully-modular PSU, delivering up to 900W peak for modern GPUs and intense gaming loads. With 80 PLUS Gold efficiency (up to 92.8%) and active PFC (0.98 power factor), it runs cooler and wastes less energy. A single, strong +12V rail (850W / 70.9A) ensures stable power delivery, while a 25 ms hold-up time helps protect against brief dips. Safety is comprehensive with OCP, OPP, OVP, OTP, SCP, UVP plus surge & inrush protection. Connectivity is future-ready: 20+4 ATX, CPU 4+4 + EPS, 4× 6+2 PCIe, 1× 12-pin, 6× SATA, and 2× Molex. Quiet active cooling uses a 120mm rifle-bearing fan for low noise and long life (100,000h MTBF).
