250 W ATX Power Supply

The KHACHIMO EVOC ATX 810 820 delivers 250 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility allows extremely fast wake-from-sleep transitions. A zero-RPM fan mode stops the fan completely at low and medium loads for near-silent operation.

Home and Office Builds

This unit suits compact desktops, office workstations and media PCs that need efficient, quiet power without high wattage. Its low-load efficiency and silent fan behaviour benefit systems that spend long periods idle or in sleep states. Builders planning dedicated graphics cards, multi-drive arrays or heavy overclocking should look at higher-capacity models instead.

250 W Maximum Output

The 250 watt rating is the single figure that determines whether this supply can support your components. Add the peak power draw of your CPU, graphics card, drives and peripherals; if the total approaches or exceeds 250 watts, this unit will not provide enough headroom for stable operation.

Questions about this item

What sustained load does the 250 W rating represent for this PS-7270B unit?

The 250 W figure is the continuous output rating for the PS-7270B, meaning it can deliver that power steadily under normal operating conditions.

How loud is the fan when the supply runs all day at typical loads?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, so the unit runs silently for much of the day; the fan only spins when higher loads demand active cooling.

Which motherboard power connectors must my board provide for this ATX supply to work?

This is a standard ATX power supply, so your motherboard needs the usual 24-pin main connector and the 4-pin or 8-pin CPU power connector that ATX boards require.
