ATX Power Supply for Modern Standby Systems

This ATX power supply is built for desktops that use Modern Standby sleep states. It delivers 14.5V output with 2.1A and 3.6A current ratings to match the YMFEV-1050XIXB specification. The unit suits builders who want efficient, low-noise power for compatible motherboards.

80 PLUS Gold Efficiency Limits

Certified at the 80 PLUS Gold level, the unit maintains high efficiency across typical loads to reduce waste heat and fan noise. Resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and minimises coil whine. Efficiency drops at very light or peak loads, so extreme edge cases fall outside the certified range.

Capacity Headroom for Low-Load and Idle States

The Zero RPM fan mode stays off at low and medium loads, giving near-silent operation during idle and Modern Standby wake cycles. The 1050 model designation indicates its rated capacity ceiling. Systems drawing sustained power beyond this rating will lose the silent and efficiency benefits.

Questions about this item

What does the 1050 in the model number mean for my build?

The 1050 identifies this specific unit; it is an ATX power supply rated for 14.5 V output with 2.1 A and 3.6 A current limits, designed for compatible YM systems.

How does the 80 PLUS Gold rating affect daily use?

80 PLUS Gold means the supply runs at high efficiency, so it draws less power from the wall, generates less heat and keeps fan noise lower during typical workloads.

What does the ATX form factor limit in practice?

ATX defines the physical size and connector layout, so this unit fits standard ATX cases and motherboards but will not suit smaller SFX or TFX chassis.
