Gamdias HELIOS P2-850G V2 850W 80+ Gold ATX 3.1 & PCIE 5.1 Fully Modular Power Supply

The Gamdias HELIOS P2-850G V2 is a premium 850W fully modular power supply built for modern gaming PCs, workstations, and next-generation GPU setups. Designed with ATX 3.1 and PCIe 5.1 readiness, it includes a native 12V-2x6 (12+4 pin) cable, making it ideal for newer graphics cards like RTX 40 and RTX 50 series without needing bulky adapters. Its 80 PLUS Gold certification ensures around 90% efficiency at 50% load, reducing wasted power, heat, and electricity costs while keeping system performance stable under heavy gaming or rendering loads.The PSU uses a full DC-DC + LLC resonant circuit design, which improves voltage stability and ripple control for sensitive components such as CPUs and GPUs. It also features Active PFC (PF 0.99) for cleaner power delivery and better energy efficiency. With a single +12V rail delivering up to 70.8A, it can comfortably power high-end CPUs and powerful GPUs in demanding systems.Cooling is handled by a 120mm hydraulic bearing fan with automatic temperature-based speed optimization, keeping noise low during light workloads while scaling airflow under load. For safety, Gamdias includes a full suite of protections: OVP, UVP, OPP, SCP, OCP, and OTP, protecting your PC against over-voltage, under-voltage, short circuits, overheating, and overload issues.Because it is fully modular, users only connect the cables they need, which improves cable management, airflow, and overall build cleanliness. The PSU also includes 2 CPU connectors, 4 PCIe 6+2 connectors, 6 SATA, 3 Molex, and 1 native 12V-2x6 cable, making it suitable for powerful gaming rigs, streaming setups, and creator PCs. It comes with a strong 10-year warranty, adding confidence for long-term use.
