Gamdias Helios P2-850G 850 Watt 80 Plus Gold ATX 3.0 SMPS

The Gamdias Helios P2-850G is an 850-watt power supply built for modern high-performance gaming and workstation builds. Carrying the ATX12V v3.0 standard, it is fully compatible with PCIe Gen 5.0 graphics cards and features a native 16-pin 12VHPWR connector capable of delivering up to 450W to the GPU — making it a strong match for current-generation NVIDIA and AMD flagship cards. Efficiency sits at the 80 Plus Gold tier, which translates to up to 92% efficiency at 50% load. A high-quality Active Power Factor Correction (APFC) stage keeps the power factor value at 0.99, contributing to cleaner power draw from the wall. The DC-to-DC converter topology, combined with a full-bridge LLC resonant circuit and 12V synchronous rectification, ensures a rock-solid +12V rail output — the rail most critical to CPU and GPU stability under gaming and sustained workloads. Thermal management is handled by a 120mm hydraulic bearing fan. A smart fan controller modulates speed based on system load, allowing the PSU to operate quietly during light workloads. The unit is also rated to support C6/C7 low-power states and carries ErP Lot 6 environmental compliance. The comprehensive protection suite covers six distinct scenarios: Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Over Temperature Protection (OTP), and Short Circuit Protection (SCP) — providing a reliable safety net for the entire system. Connector support is extensive, including one 24-pin main power, two 4+4-pin CPU EPS, four 6+2-pin PCIe, one 12+4-pin 12VHPWR, six SATA, and three 4-pin Molex. Flat cables are included for easier routing, though the unit is a non-modular design.
