PowerEdge T300 490W ATX supply

The KHACHIMO PowerEdge T300 is a 490W ATX power supply designed for desktop PCs that require reliable, efficient power delivery. It suits system builders who want 80 PLUS Gold efficiency and modern standby support in a standard form factor.

Compatibility checks before ordering

Verify that your case accepts a standard ATX power supply and that your motherboard uses a 24-pin main connector plus the required CPU and GPU power cables. Ensure the total system power draw stays within the 490W rating.

Behaviour under sustained load

The resonant LLC topology with DC-to-DC conversion maintains clean, consistent output during extended workloads. Zero RPM fan mode keeps the unit silent at low and medium loads, while 80 PLUS Gold certification helps limit heat and noise when the supply runs continuously near its rated capacity.

Questions about this item

Does the KHACHIMO 490W unit ship with all cables needed for a standard ATX build?

The power supply uses a standard ATX form factor and includes the fixed cable set required for motherboard, CPU and graphics connections, so no extra cable kit is necessary for a typical build.

Should I choose the N490P-00, H490P-00 or JY138 version for my Dell PowerEdge T300?

All three part numbers — N490P-00, H490P-00 and JY138 — refer to the same 490 watt design; pick whichever matches the label on the unit you are replacing.

What does the 490W rating actually deliver inside a working server?

The 490 watt rating is the continuous output the supply can sustain across its rails while meeting 80 PLUS Gold efficiency, Modern Standby wake requirements and Zero RPM fan thresholds in a live system.
