350W ATX Power Supply

The KHACHIMO MRW-6350P-R is a 350W ATX power supply built for mainstream desktop builds and office workstations. It delivers 80 PLUS Gold efficiency to reduce waste heat and running costs. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. This unit suits users who need reliable, quiet power without excess capacity.

Straightforward ATX Installation

Standard ATX dimensions and cable layout allow direct fitment into most compliant chassis without adapters. The Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine for quieter operation. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. Ensure the case supports ATX form factor and that total system draw stays within the rated output.

350W Capacity and Headroom

Rated at 350W continuous output, the supply comfortably handles typical office PCs, home media centres and entry-level gaming rigs with modest graphics cards. Gold-certified efficiency keeps power consumption, noise and temperatures lower across the load range. It runs out of headroom in high-end multi-GPU configurations or systems with heavily overclocked CPUs and GPUs. Builders planning such loads should select a higher-wattage unit.

Questions about this item

How can I confirm the PSU is delivering stable 350W output after installation?

Monitor system stability under load and check that the fan remains off during low-power states, indicating the Zero RPM mode and LLC topology are functioning.

Which cables and connectors are included with the MRW-6350P-R and what must I purchase separately?

The unit ships with fixed ATX power cables; any custom sleeved extensions or specialised GPU adapters are separate purchases.

Should I choose this 350W Gold model or a higher-wattage version for a modern standby build?

Select this 350W model if your peak system draw stays below 350W; it provides 80 PLUS Gold efficiency and Modern Standby support at this capacity.
