KHACHIMO H1300EF-02 1300W ATX power supply

Dell Workstation Power Replacement

The KHACHIMO H1300EF-02 is a 1300W ATX power supply built to replace the original unit in Dell Precision T5810, T7610, T7810 and T7910 workstations. It delivers the high wattage these towers demand for multi-GPU configurations and heavy compute workloads.

Capacity and Headroom

At 1300W this unit comfortably powers dual high-end graphics cards, large memory populations and multiple storage drives simultaneously. The resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight across the major rails, so the supply runs out of headroom only when the combined system draw approaches the rated maximum.

ATX Interface Limits

The ATX form factor and fixed cable layout restrict installation to chassis designed for this specific Dell pin-out; builders using standard ATX motherboards or custom loop radiators will find the connectors incompatible. Modern Standby support and zero-RPM fan mode function only when the host platform implements the corresponding low-power states.
