500W ATX power supply for basic desktops

This myVolts ATX unit delivers 500W rated output with manual 115/230V switching. It targets low energy consumption, low noise basic desktop systems. The 20+4 pin motherboard connector, dual 4 pin CPU connectors, four SATA ports and a 6 pin to 6+2 pin video card interface cover standard builds. A 1.1m power cord is included.

Thermal sensor fan control and >80% efficiency

An internal thermal sensor controls the 12cm fan speed automatically to match load. Efficiency exceeds 80 percent under normal use. Hold-up time is greater than 10ms. The unit has no active PFC and relies on manual voltage selection. Rated service life is 100000 hours.

Sustained load behaviour within 500W rating

Under continuous load the fan speed rises as the thermal sensor dictates, keeping component temperatures in check. Output remains stable up to the 500W rating with hold-up time above 10ms. The supply suits workloads that stay within its rated capacity rather than short peak bursts.

Questions about this item

How do I install the 20 + 4 pin motherboard connector without bending pins?

Align the keyed 20 + 4 pin connector with the motherboard socket, press straight down until the latch clicks, and avoid angling the plug which bends the delicate pins.

Which part will need replacement first during long‑term use?

The 12 cm fan with its internal thermal sensor is the only moving component and will typically require replacement after the rated 100000 hour service life.

What limits sustained output before the unit shuts down?

Efficiency is rated above 80 percent with no active PFC, so heat buildup under continuous 500 W load triggers the thermal sensor to spin the fan faster and can activate over‑temperature protection.
