Technical specification
The GAMDIAS HELIOS P1A-850G Fully Modular is an 80 PLUS Gold certified 850 W ATX power supply designed to deliver powerful, efficient and stable power for high-performance gaming and creator PCs. It uses a full DC-to-DC structure with full bridge LLC resonance and 12 V synchronous rectification for cleaner output and better stability, achieving up to 90% efficiency and reducing wasted power and heat. A 120 mm hydraulic-bearing smart fan automatically adjusts its speed based on temperature and load, while fully modular flat black cables, high-quality capacitors and a full protection suite (OVP, UVP, OPP, OCP, OTP, SCP) ensure a clean build and long-term reliability.
