  • TypeAT
  • Quick installation with clearly marked connectors
  • Low energy use and quiet operation for basic desktops
  • Automatic fan control via internal thermal sensor
  • High safety from strict quality control and assurance
  • Long service life using durable, high-quality materials

Basic desktop power supply

The myVolts ATX-500W delivers a rated 500W output for standard office or home computers. It uses an AT form factor with a 20+4 pin motherboard connector, dual 4-pin CPU power leads, four SATA connectors and a 6-pin to 6+2-pin graphics lead. A 12cm fan adjusts speed automatically via an internal thermal sensor. Efficiency exceeds 80 percent.

Upgrade from lower-wattage units

This unit replaces older or lower-capacity supplies when a system needs more headroom for additional drives or a mid-range graphics card. The jump is worthwhile when the existing supply cannot sustain 500W or lacks the necessary PCIe power connector. It supports manual 115V or 230V input selection for different mains environments.

Limits of the ATX interface

The supply provides only a single 6-pin to 6+2-pin graphics connector, so it cannot power cards requiring two dedicated PCIe power inputs. Hold-up time is rated above 10ms, which covers brief mains interruptions but not extended outages. Design lifespan is 100000 hours under normal operating conditions.

Questions about this item

What case clearance does the 140 x 150 mm ATX-500W need?

The unit measures 140 x 150 x 12 mm, so allow at least that depth and width inside the chassis for the power supply to seat correctly.

Which connector is often missed when wiring the 20+4 pin motherboard interface?

The 20+4 pin plug splits; the extra 4 pins must click into the socket beside the main 20 pins or the board will not post.

When should the 12 cm fan be cleaned on a unit rated for 100000 hours?

Dust the 12 cm fan intake every six to twelve months; the thermal sensor adjusts speed automatically, but blocked airflow shortens the rated lifespan.
