GIGABYTE
A fully modular 850 W ATX power supply with 80 Plus Gold efficiency and a 120 mm hydraulic-bearing fan that stops below 20 % load
Options ATX 80+ Gold (850W)
The GIGABYTE GP-P850GM is an ATX 12V v2.31 power supply rated for 850 W of continuous output. A fully modular cable set lets builders connect only the leads they need, reducing clutter and improving airflow inside the case. The unit carries 80 PLUS Gold certification, guaranteeing 90% efficiency at typical load.
This supply fits mid-range and high-end single-GPU systems that demand clean cable routing and quiet operation. The 120 mm hydraulic-bearing fan stops completely below 20% load, keeping noise near zero during idle or light work. Builds planning multiple graphics cards should look elsewhere because only four PCIe 6+2-pin connectors are provided.
All 850 W are available on a single +12 V rail, so the CPU and GPU draw from one unified power pool without rail-balancing concerns. Active PFC with a typical power factor above .9 ensures stable input across 100–240 V mains. Japanese main capacitors and a full protection suite (OVP, OPP, SCP, UVP, OCP, OTP) back long-term reliability.

같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
The unit follows ATX 12V v2.31 and provides a 20+4-pin main connector plus a single +12V rail rated at 850 W, matching the physical and electrical interface used by earlier ATX 12V motherboards.
The fan spins up at power-on and remains off below 20% load; you can hear it start when the system draws more power and verify the 80 PLUS Gold efficiency by checking that the unit stays cool at typical loads.
The fully modular package includes the 20+4-pin ATX cable, four 6+2-pin PCIe cables, eight SATA power cables and peripheral cables; no extra cables are required for a standard build.
