GAMDIAS Helios P2-850G 850 Watt 80 Plus Gold Non Modular ATX 3.0 Power Supply (Black)

The GAMDIAS Helios P2-850G is an 850-watt ATX 3.0 power supply rated at 80 Plus Gold efficiency, designed to meet the power demands of modern high-performance PC builds including systems running PCIe Gen 5.0 graphics cards. Built around a full DC-DC architecture with LLC resonant circuit design and 12V synchronous rectification, the unit maintains stable voltage across all rails during demanding workloads. At the heart of the cooling system sits a 120 mm hydraulic bearing fan. The fan adjusts speed based on thermal load, allowing the PSU to operate quietly under lighter workloads while ramping up airflow when the system demands more. According to the specifications, a dedicated silent mode switch is not included, but the smart fan control handles thermal management automatically. One of the most notable features of the Helios P2-850G is its native 16-pin 12VHPWR (12+4-pin) connector, which can deliver up to 450 W directly to compatible PCIe 5.0 graphics cards without the need for adapters. This is complemented by four 6+2-pin PCIe connectors for additional GPU or peripheral power, making the unit suitable for a wide range of current-generation and next-generation GPU configurations. The PSU is non-modular, meaning all cables are permanently attached. Flat cable design is included to assist with cable routing in the chassis. Active Power Factor Correction (APFC) achieves a power factor value of 0.99, and the unit supports C6/C7 low-power processor states. Environmental compliance is certified to ErP Lot 6 standards. Six independent protection circuits safeguard connected components: Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Current Protection (OCP), and Over Temperature Protection (OTP). The PSU carries a 3-year warranty from GAMDIAS.
