250W ATX Power Supply

The KHACHIMO H78007 is a 250W ATX power supply built for TDK-Lambda Sinus CSF250TM compatibility. It delivers 80 PLUS Gold efficiency and supports Modern Standby for rapid wake-from-sleep. Resonant LLC topology with DC-to-DC conversion provides stable output and reduced coil whine.

Suitable for low-power system builders

This unit suits builders replacing a 250W TFX or flex-ATX supply in compact workstations or thin clients that require the specific H78007 pinout. It is not for users needing higher wattage for discrete graphics cards or multi-drive arrays. The fixed 250W limit also rules out future upgrades to power-hungry components.

80 PLUS Gold efficiency rating

The 80 PLUS Gold certification guarantees high efficiency at typical loads, lowering electricity draw and heat output. Combined with a Zero RPM fan mode that stops the fan at low and medium loads, the power supply runs silently during everyday office tasks.

Questions sur cet article

At what load does the 250 W limit become the first constraint under sustained use?

The unit is rated for 250 W continuous output; sustained loads above that level will trigger protection or shutdown.

How much fan noise and heat should I expect when the supply runs all day at typical loads?

Zero RPM Fan Mode stops the fan completely at low and medium loads, giving near-silent operation and cooler temperatures thanks to 80 PLUS Gold efficiency.

Which motherboard power connectors must my system already provide for this ATX unit to work?

Standard ATX 24-pin main connector and 12 V CPU/EPS connector are required; the PSU delivers 5 V, 12 V and 24 V rails to match those inputs.
