500W ATX Power Supply

The myVolts ATX-500W delivers 500W of continuous power for basic desktop builds that prioritise low energy draw and quiet operation. It fits standard ATX layouts and ships with a British flag style power cord. The unit is rated for a 100000 hour lifespan using durable components.

Sustained load behaviour

An internal thermal sensor automatically adjusts the 12cm fan speed so airflow matches the actual heat output rather than running at a fixed rate. Hold-up time exceeds 10ms and efficiency stays above 80 percent during extended sessions. Manual voltage selection between 115V and 230V input is required before powering on.

Installation and common issues

Clearly labelled connectors including a 20+4 pin motherboard plug, dual 4 pin CPU power, four SATA ports and a 6 pin to 6+2 pin graphics lead simplify cable routing for first time builders. The compact 140 x 150 x 12mm chassis fits tight cases but offers no active PFC correction. Buyers who need active power factor correction or modular cabling should consider other units.

Questions about this item

How loud and hot does the 12 cm fan get when the 500 W unit runs all day?

The 12 cm fan speed is automatically controlled by an internal thermal sensor, so it only spins faster when the supply gets hotter, keeping noise and heat low during continuous use.

Which cables must my build already have to plug into the 20+4 pin motherboard and 4+4 pin CPU connectors?

All required cables are permanently attached to the unit, including the 20+4 pin motherboard connector, the 4+4 pin CPU connector, four SATA plugs and a 6-pin to 6+2-pin graphics lead, so no extra cables are needed.

Will the manual 115 V/230 V switch work with my older AT-style case and components?

The supply uses a standard ATX form factor (approx. 140 x 150 mm) with a 20+4 pin motherboard connector and 4+4 pin CPU connector, so it fits modern ATX cases and boards; an older AT case or board would need an adapter not included here.
