Compact 250W modular supply

This 250W ATX power supply uses a modular design with a red 12cm fan and manual 115V/230V switching. It targets basic desktop builds that demand low energy consumption and quiet operation. The unit measures 140 x 150 x 86mm and includes a 1.1m power cord. Rated efficiency exceeds 80% with a hold time greater than 10ms.

Manual voltage and fixed connectors

The 115V/230V input requires manual switching, so the builder must set the correct position before powering on. Fan speed is managed by an internal thermal sensor rather than software control. Fixed cables provide a 20+4 pin motherboard connector, a 4 pin CPU 12V connector, two fan headers, two SATA connectors and a single 6 pin graphics connector. No active PFC is present.

Basic desktop headroom

The 250W rating suits entry-level systems with modest CPU and graphics demands. The lone 6 pin graphics connector and two SATA ports limit expansion to one mid-range GPU and a pair of drives. Rated lifespan is 100000 hours. Builders needing multiple GPUs, higher wattage or additional SATA devices should consider a larger unit.

Questions about this item

Which version of the myVolts ATX-250W should I choose for a basic desktop build?

The unit is a single 250W model with manual 115V/230V switching, a 12 cm red fan, modular cables and black finish — no other capacity or colour variants exist.

What does the 250W rating mean once the supply is installed in a real machine?

It can deliver up to 250W continuously with efficiency above 80%, hold-up time over 10 ms and a rated lifespan of 100000 hours, making it suitable for low-power desktop systems.

What interfaces are provided and what do they limit in practice?

Connectors include 20+4 pin motherboard, 4 pin CPU 12V, two SATA, one 6 pin graphics and two fan headers, so the supply supports one graphics card needing a 6 pin plug and two SATA drives.
