FNP300-1012S144G 300W ATX unit
The KHACHIMO FNP300-1012S144G is a 300W ATX switching power supply built for basic desktop systems. It delivers the standard rails needed for typical office or home PC builds. This unit suits users replacing an existing supply in a low-demand chassis. It is not intended for configurations requiring high-output 12V current or multiple discrete graphics cards.
Thermals, noise and 300W power draw
The supply operates within its 300W rating using forced-air cooling suited to normal desktop loads. Acoustic output remains at a level consistent with standard ATX designs under typical conditions. Power conversion follows the FNP300 platform specifications referenced as 1600, 3600 and 3900 AC. Efficiency characteristics match the expectations for a supply of this class.

Questions about this item
How do I install the 300 W ATX power supply and what step is often missed?
Mount the unit in the case using four screws, connect the 24-pin ATX and 4/8-pin CPU cables, then attach the 1012 peripheral connectors; the step most often missed is plugging in the 144 auxiliary power lead for the 1600/3600/3900 AC rails.
What maintenance or replacement will the FNP300-1012S144G need later?
Clean dust from the intake grill every six months with compressed air; the internal fan bearings are rated for continuous operation, so plan to replace the whole 300 W unit only if voltages drift outside ATX spec after several years.
