About this product
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.
80 PLUS Gold efficiency: Gold certification guarantees stable power output with up to 90% efficiency, reducing power loss and heat versus lower-tier units.
Full DC-to-DC, LLC resonant design: DC-to-DC structure with full bridge LLC resonance and 12 V synchronous rectification improves performance, voltage stability and safety.
120 mm hydraulic-bearing smart fan: Hydraulic-bearing fan supports automatic speed optimization according to temperature and load for quieter operation and longer lifespan.
Fully modular flat cables: Fully modular design with flat black cables simplifies cable management, improves airflow and keeps the interior clean.
Heavy-duty protection suite: Full protections including OVP, UVP, OPP, OCP, OTP and SCP help protect your system from electrical faults.
