300 W ATX power supply for desktop builds

This 300 W ATX unit delivers 80 PLUS Gold efficiency for lower consumption and heat. Modern Standby compatibility gives fast wake-from-sleep and better low-load performance. It suits standard desktop PCs that need reliable, quiet power.

Simple ATX fit with silent low-load operation

The supply uses standard ATX connectors and mounting holes for straightforward installation in compatible cases. Zero RPM fan mode stops the fan at low and medium loads for near-silent running. Resonant LLC topology with DC-to-DC conversion reduces coil whine and keeps output clean.

300 W continuous output

The single rating that decides fit is the 300 W continuous power rating. Systems with high-end graphics cards or many drives may exceed this limit and need a higher-wattage unit. Check your total component draw before buying.

Questions about this item

How can I confirm the 300 W unit is running correctly after installation?

Verify the 80 PLUS Gold efficiency rating is active by monitoring low power draw and listen for the Zero RPM fan mode keeping the unit silent at light loads.

What comes with the TIS 300-124 and what must I source separately?

The power supply includes the ATX unit with Modern Standby support; mounting brackets, cables and any DIN rail clips are not included and must be purchased separately.

Which capacity should I choose for a DIN rail build needing 300 W output?

The 300 W model marked 124 is the only capacity listed, so select this version when your design calls for exactly 300 watts of switching power.
