Compact 450W Gold PSU

The KHACHIMO ENP-7145B is a 450W ATX power supply built to the 80 PLUS Gold efficiency standard. It targets system integrators and compact PC builders who need reliable power delivery in a 1U-compatible form factor. Modern Standby support ensures quick wake times and improved low-load efficiency for always-ready desktops.

Thermals, noise and power draw

Gold-rated efficiency reduces wasted energy, lowering overall power consumption and heat output during normal operation. A Zero RPM fan mode stops the cooling fan entirely at low and medium loads, delivering near-silent performance for office or media centre use. The resonant LLC topology with DC-to-DC conversion further minimises coil whine while maintaining stable voltages.

Topology and sleep-state benefits

The resonant LLC design paired with DC-to-DC conversion supplies clean, consistent power across all rails and reduces audible coil noise. This architecture enables the use of deeper, more energy-efficient sleep states supported by Modern Standby. Together, these features improve system responsiveness after sleep and contribute to quieter, cooler running conditions.

Domande su questo articolo

How do I install the ENP-7145B in a 1U chassis and which step is often missed?

Mount the unit with its four screws, connect the 24-pin ATX, 4+4-pin CPU and peripheral cables, then verify the motherboard's Modern Standby setting is enabled in BIOS so the fast wake and low-load efficiency features actually work.

What maintenance will this power supply need later?

The Zero RPM fan stops at low and medium loads, so dust builds up unseen; vacuum the intake grill once a year and listen for bearing noise — if the fan stays loud under load, replace the whole unit.

What limit appears first when the ENP-7145B runs at sustained high load?

The 450 W continuous rating is the hard ceiling; the LLC resonant topology with DC-to-DC conversion keeps voltage stable up to that point, but exceeding it triggers over-power protection and shuts the system down.
