300W ATX Power Supply for Modern Standby Systems

This 300W ATX unit targets builders who need fast wake-from-sleep performance and quiet operation. Gold-rated efficiency cuts power draw and heat, while the Zero RPM fan mode keeps noise near zero at typical desktop loads. The resonant LLC topology with DC-to-DC conversion delivers stable voltage rails and supports deep sleep states.

Ideal for Office PCs, Not for High-End Gaming

Suits compact or office builds that rely on Modern Standby and value silent idle behaviour. Builders who need more than 300W for discrete graphics cards or heavy multi-core workloads should look at higher-capacity units.

300W Continuous Output Rating

The 300W rating is the single figure that decides fit. If the total system draw under load stays below this limit, the supply will handle it with Gold efficiency and silent low-load operation.

Perguntas sobre este artigo

Will this ATX unit fit a standard ATX case and does it need a 6-pin connector from the motherboard?

It follows the ATX form factor so it mounts in any standard ATX chassis, and the 6-pin connector listed is a peripheral power output, not a motherboard input.

What is the correct order for connecting the 24-pin ATX, 8-pin CPU and 6-pin peripheral cables during installation?

Seat the PSU in the case first, then plug the 24-pin motherboard cable, the 8-pin CPU cable, and finally any 6-pin peripheral cables, making sure each latch clicks fully home.

How often should the internal fan be cleaned to keep the Zero RPM mode working reliably?

Vacuum or blow out the fan grille once a year, or more often in dusty environments, so the fan can spin freely when loads rise above the Zero RPM threshold.
