5 V 60 A switching supply for industrial builds

The KHACHIMO HWS300-5/WS is a 300 W ATX-type switching power supply that delivers a single 5 V rail rated at 60 A. It is intended for system integrators and maintenance teams who need a direct replacement for the TDK-Lambda HWS300-5 in test rigs, automation cabinets or legacy equipment. Each unit is tested working before dispatch.

Thermals noise and power draw in normal use

The supply converts mains input to a regulated 5 V output at up to 300 W continuous load. Internal switching topology keeps heat output proportional to the drawn current, so a lightly loaded unit runs cooler than one near the 60 A limit. Fan noise scales with thermal load and remains within typical industrial tolerances for rack or enclosure mounting.

Questions about this item

How is the ATX power supply installed, and which connector step is often missed?

Mount the unit in the case, secure it with four screws, then plug the 24-pin ATX motherboard connector and the 4-pin or 8-pin CPU power cable; the CPU power cable is the step most builders forget.

What maintenance will the 300 W unit need later?

Clean dust from the intake grill and fan blades every six to twelve months with compressed air; if the 60 A 5 V rail ever drops out of regulation, the entire supply must be replaced.
