About this product
The GAMDIAS HELIOS M1-550B is an 80 PLUS Bronze certified 550 W non-modular ATX power supply designed for reliable, efficient power delivery in mid-range gaming and productivity PCs. It offers up to 85% efficiency, an active PFC design with PF up to 0.99, a 120 mm hydraulic-bearing smart fan with automatic speed optimization and heavy-duty protections (OVP, UVP, OPP, SCP, OCP). Flat black cables, support for Intel C6/C7 power states and dual 6+2-pin PCIe connectors make it a strong choice for single-GPU gaming systems that demand stability and quiet operation.
80 PLUS Bronze certified (up to 85% efficiency): Delivers stable 550 W output at up to 85% efficiency, reducing wasted power and heat compared to non-certified PSUs.
120 mm hydraulic-bearing smart fan: Automatic fan speed optimization adjusts RPM according to temperature and load, ensuring quieter operation during light use and enhanced cooling under stress.
Active PFC and heavy-duty protections: APFC with PF up to 0.99 plus protections (OVP, UVP, OPP, SCP, OCP) provide more stable voltage and safeguard your system from shorts, overloads and abnormal voltages.
Modern connectivity with dual PCIe: Includes 1 × 20+4-pin ATX, 1 × 4+4-pin EPS CPU, 2 × 6+2-pin PCIe, 5 × SATA and 3 × Molex, covering typical mid-range gaming builds with multiple drives and one discrete GPU.
Flat black non-modular cables: Flat black cables simplify routing and improve airflow in most ATX and micro-ATX cases while keeping cost lower than modular units.
