300 W ATX Power Supply

The KHACHIMO T3640 T3650 is a 300 W ATX power supply built for desktop PCs that require reliable, efficient power delivery. It suits system integrators and upgraders who need a compact unit with modern standby support and quiet operation.

80 PLUS Gold Efficiency

This unit carries 80 PLUS Gold certification, meaning it meets high efficiency targets at typical loads to reduce electricity draw and heat output. That single rating is the clearest indicator of whether the supply matches a build’s efficiency and thermal requirements.

Zero RPM Fan & LLC Topology

A zero RPM fan mode stops the fan completely at low and medium loads for near-silent running, while resonant LLC topology with DC-to-DC conversion delivers clean power, reduces coil whine and enables deeper sleep states. Together they change the acoustic profile and standby behaviour of the finished PC.

Questions about this item

What does the 300 W rating mean for my build?

It is the maximum continuous power the unit can deliver across all rails, so the combined draw of CPU, GPU, drives and peripherals should stay below that figure.

What does the 80 PLUS Gold certification actually guarantee?

It confirms the supply meets the Gold efficiency thresholds defined by the 80 PLUS programme at the standard test loads.

Will this ATX power supply fit a standard tower case?

Yes, the ATX form factor matches the mounting holes and dimensions used by most mid-tower and full-tower chassis.
