600W Modular Upgrade Model Available

High efficiency 80PLUS design allows the unit to operate with less heat and lower cooling fan noise than most PC power supply models in the market. This HIGH POWER unit operates anywhere in the world automatically with a wide AC input voltage range from 100V to 240V.  Modular cable management design allows use of only the cables you need to improve internal airflow and reduce clutter.  New flat modular cables now take up even less space and further improve airflow.

RoHS Compliant - made with hazardous-free components
RoHS is the Restriction Of the use of certain Hazardous Substances in electrical and electronic equipment. This has been a standard in Europe and is now becoming a standard in the world. Not only lead, but cadium, mercury, hexavalent chromium, polybrominated biphenyl (PBB), and polybrominated diphenyl ether (PBDE) flame retardants are limited as well.

Start Stability
No Load Start
When power is applied to HPG-550ST-F14C with no load connected or under minimum load connected, neither damage to power supply nor hazards to users will occur.
Cold Start
 The power supply shall operate properly when first applied at

            Operating temperature range: 10 - 40 degree C (50 - 104 degree F)
            Operating relative humidity range: 20 to 90%
            Storage temperature range: -40 - 70 degree C
            Storage relative humidity range: 20 to 95%
            Altitude: operate normally at any altitude between 0 to 10000 feet.
            Energy-efficient: 81.11% minimum, 83.32% typical
            Mean Time Between Failure, including the life of the fan: 50,000 hours (more than 5 years)

Power Good Signal 100~500ms
Hold Up Time >16 ms
Dimensions: 150x160x86mm

  • Remote On/Off Controlled mode
The PSON# signal is required to remotely turn on/off the power supply, PSON# is an active low signal that turns on the output power rails. When this is not pulled low by the system, or left open, the outputs (except the +5VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the power supply. 
TTL level "H" 2.0 V - 5.25 V;  "L" 0.0 V 1.0 V

Mechanical Design
    • Massive 140mm fan draws heat from CPU area and cools the power supply at the same time. Special slippery circular tube design black anodized fan-guard allows air to flow in smoothly and quietly while providing protection against unintended installation injury.
    • Modular cable design allows unneeded power connectors and cables to be removed from the system and free up more space inside the system for better air flow

Dimensions: 150x160x86mm

Packaging: Individually packed in white box with installation screws and UL safety power cord.
