Entry-level ATX power supply

The myVolts ATX-500W delivers 500W of rated power for basic desktop systems with low energy consumption. Clearly marked connectors make installation quick and easy. It accepts 115V or 230V input with manual switching and offers an efficiency above 80%. A 20+4 pin motherboard connector, dual 4-pin CPU power, four SATA connectors and a 6-pin to 6+2-pin graphics adapter cover standard component needs.

Thermally controlled fan and power draw

A 12cm fan adjusts its speed automatically using an internal thermal sensor to keep noise low during normal use. The unit specifies a hold-up time greater than 10ms and a design lifespan of 100000 hours. No active PFC circuitry is present, so the supply relies on the manual voltage selector for input compatibility.

Included power cord and connector layout

The package supplies the power supply unit and a single power cord. All cable ends are labelled for straightforward routing, and the fixed cable set provides two fan headers alongside the main power, CPU, SATA and graphics connections. No software or additional accessories are bundled.

Questions about this item

How do I connect the 20+4 pin motherboard connector and the 4+4 pin CPU cable correctly?

Line up the keyed 20+4 pin block with the motherboard socket and press until it clicks; the 4+4 pin CPU plug splits for 4-pin or 8-pin headers — use only the half that matches your board.

What maintenance will the 12 cm fan need over its 100000 hour rated life?

Blow dust from the fan grille every few months; the thermal sensor auto-adjusts speed, so no manual lubrication or setting changes are required.

At what load does the >80 % efficiency floor limit continuous output?

The 500 W rating is the maximum sustained draw; running near that level keeps efficiency at the stated floor, so plan loads with headroom below 500 W.
