400W 80 Plus Gold ATX power supply

This KHACHIMO DP400-3512D delivers 400W of continuous power through a standard ATX form factor. It targets system builders who need reliable efficiency for mainstream desktops or workstations. The 80 Plus Gold certification ensures high energy conversion, reducing waste heat and operating cost. It suits modern PCs that use low-power sleep states.

Installation uses standard ATX mounting

The unit fits regular ATX cases and uses the usual motherboard, CPU and peripheral cables. Zero RPM mode keeps the fan off at low and medium loads, so noise stays minimal during typical work. Resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation. Ensure your case has enough depth for a standard ATX supply before ordering.

400W capacity covers mainstream builds with headroom

The 400W rating comfortably handles mid-range CPUs and single graphics cards in everyday productivity or light gaming. Efficiency stays high across the load range thanks to Gold certification. Systems with multiple high-end GPUs, extreme overclocking or very heavy multi-rail draws will exceed this unit's capability. Modern Standby support enables fast wake times for compatible platforms.

Perguntas sobre este artigo

How can I confirm the 400W unit is delivering stable power after installation?

Check that the system boots reliably, runs stress tests without shutdowns, and that the fan stays off at idle thanks to the Zero RPM Fan Mode, indicating the Resonant LLC topology with DC-to-DC conversion is regulating cleanly.

Which cables and accessories are included with the DP400-3512D and what must I source separately?

The box contains the ATX power supply unit itself; all modular cables required for your motherboard, graphics card and drives must be purchased separately if not already owned.

Should I choose the 80 PLUS Gold 400W model or a different capacity for a Modern Standby build?

Select the 400W Gold unit when your peak load stays comfortably below that wattage, as its Modern Standby compatibility and high low-load efficiency suit sleep-heavy workflows; choose a higher capacity only if your components demand more headroom.
