260 W ATX Power Supply

This 260 W ATX unit is built for compact desktop builds and workstation refreshes that need reliable power without excess capacity. It suits system integrators and home-office users who want an efficient, quiet supply for everyday workloads and Modern Standby sleep states.

Sustained load efficiency and acoustics

The 80 PLUS Gold certification means the supply maintains high efficiency across typical operating ranges, reducing waste heat and keeping internal temperatures lower during long sessions. Zero RPM fan mode stops the fan completely at low and medium loads, so the system stays near-silent while the resonant LLC topology with DC-to-DC conversion delivers clean power and suppresses coil whine under continuous demand.

Straightforward ATX installation

Standard ATX dimensions and a single 4-pin connector simplify mounting in compatible chassis, and the Modern Standby design enables extremely fast wake-from-sleep without extra configuration. Builders must verify that the 260 W ceiling and the lone 4-pin header meet the power and connector needs of their specific motherboard and components before purchasing.

Questions about this item

How loud and hot does the 260 W unit get when it runs all day?

The 80 PLUS Gold rating keeps efficiency high, so waste heat and fan noise stay low; Zero RPM mode stops the fan entirely at light and medium loads for near-silent operation.

Which connectors must my build already have for this PSU to work?

It uses a standard ATX form factor with a 4-pin power connector, so your motherboard needs a matching 4-pin ATX socket.

Will the 260 W model start reliably with an older motherboard that only supports legacy sleep states?

Resonant LLC topology with DC-to-DC conversion enables modern energy-efficient sleep states while still delivering clean power to older platforms.
