Purpose and audience

The KHACHIMO M1S-3400V is a 400 W ATX power supply built for standard desktop builds. It suits office workstations, home PCs and basic gaming rigs that do not demand high-wattage overhead.

Build integration

The unit follows the ATX form factor so it mounts in any compatible chassis with the usual screw pattern. Its 400 W rating leaves headroom for a mid-range graphics card and several drives while keeping cable routing straightforward.

Upgrade context

This model replaces older or lower-capacity ATX units that can no longer deliver stable power under load. The jump is worth it when a system shows random shutdowns or when adding components that push the previous supply past its limit.

商品問答

At what sustained load does the 400W rating become the limiting factor?

The 400W maximum output is the first limit reached when total system draw approaches that figure under sustained use.

How much heat and noise should I expect when the unit runs all day near its 400W capacity?

Operating continuously at high load will increase both fan noise and case temperatures as the supply dissipates more waste heat.

Which ATX power cables must my motherboard and graphics card already provide for this supply to connect?

You need a motherboard with a 24-pin ATX connector and a CPU 4-pin or 8-pin header, plus any PCIe connectors your graphics card requires.
