SKU CH-T29V-M5PZ2

10-pin 300 W ATX unit with 80 PLUS Gold efficiency, zero-RPM fan mode and Modern Standby compatibility for fast wake times

  • Product typeATX
  • Faster wake from sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency
  • Near-silent operation at low loads with Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC and DC-to-DC topology
  • 300 W output through a 10-pin ATX connector

Who this is for

This ATX power supply delivers 300 W through a 10-pin connector and suits compact or legacy desktops that require this specific pin layout. It carries 80 PLUS Gold certification and supports Modern Standby for fast wake times and efficient low-load operation. Builders replacing a unit in a small-form-factor chassis or an OEM board with a matching header will find it a direct fit.

Check before ordering

Verify that your motherboard uses a 10-pin main power connector rather than the common 24-pin ATX header, as this unit will not connect to standard boards. Confirm the physical dimensions suit your case and that the 300 W capacity covers the combined draw of your CPU, GPU and peripherals. The Zero RPM fan mode activates at low and medium loads, so ensure your typical workload stays within that range for silent running.

Build and daily use

Resonant LLC topology with DC-to-DC conversion provides stable voltage regulation and reduces coil whine for quieter operation. The 80 PLUS Gold rating means lower waste heat and cooler internal temperatures during everyday use. A 10-pin connector limits compatibility to specific OEM platforms, so cable routing is straightforward but not interchangeable with standard ATX builds.

Questions about this item

Does the KHACHIMO 10Pin 300W power supply come with all cables attached or do I need to buy any separately?

The unit is a non-modular ATX power supply, so the 10-pin motherboard connector and all other leads are fixed to the chassis; nothing extra is required for a standard build.

The supplier title lists HK400-14PP, PCK013, FSP250-30AGBAA, PCE026, HK350-12PP, PA-3251-1 and PCK023 — which one should I order?

Those codes are cross-references for the same 300 W unit; choose the part number that matches your chassis or motherboard service manual and you will receive the identical power supply.

What does the 300 W rating mean when the PSU is installed in a modern PC with a discrete graphics card?

The 300 W continuous output on the +12 V rail supports mid-range GPUs and CPUs; 80 PLUS Gold efficiency keeps heat and fan noise low under typical gaming loads.
