Purpose-built PSU for MateStition S B515 and B520

This power supply is designed specifically for the MateStition S B515 and B520 desktop platforms. Its proprietary 10-pin connector matches the motherboard header on those models, so it fits without adapter cables or repinning. It is not a standard ATX unit for generic builds.

Integration and space savings

The compact switching design frees internal volume inside the small-form-factor chassis these systems use. Because the 10-pin interface carries all required rails, builders do not need extra 24-pin or 4-pin cables that would otherwise clutter the tight layout. It is unsuitable for boards that require a standard 24-pin ATX connector.

Thermals, noise and power behaviour

At 300 W continuous output the unit meets 80 PLUS Gold efficiency, reducing waste heat and keeping internal temperatures lower. The Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, while the resonant LLC topology with DC-to-DC conversion minimises coil whine and supports Modern Standby for rapid wake times.
