GAMDIAS Helios M1 550B 550W 80+ Bronze Non Modular ATX 2.0 Power Supply ( 550W )

The GAMDIAS Helios M1 550B is a 550W non-modular ATX 2.0 desktop power supply carrying an 80 Plus Bronze certification. That certification requires the unit to deliver power at up to 85% efficiency under typical load conditions, reducing wasted heat and helping to keep your electricity consumption in check compared to non-certified alternatives. Cable management is simplified by the included flat black cable set. Unlike round or sleeved bundles, flat cables lie flush against the chassis interior, making routing around motherboard trays and drive bays noticeably tidier and leaving more room for airflow between components. Cooling is handled by a 120mm hydraulic-bearing fan whose speed is adjusted automatically based on internal temperature and load. The hydraulic bearing design is generally associated with lower noise at moderate speeds and a longer operational lifespan than sleeve-bearing alternatives, making it a sensible choice for a always-on desktop environment. The Helios M1 550B includes Active Power Factor Correction (APFC) with a stated power factor value of 0.99, meaning the unit draws current from the wall in a highly efficient, near-unity relationship with its actual power output. It also supports Intel C6/C7 deep sleep power states, allowing modern platforms to drop into their lowest idle modes without the PSU losing voltage regulation. A comprehensive protection suite guards connected components: Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), and Over Current Protection (OCP) are all built in, helping to shield your GPU, CPU, storage, and motherboard from electrical faults.
