ATX power supply delivering 12 V at 4.4 A with 50 W output and 80 PLUS Gold efficiency

  • TypeATX
  • Fast wake from sleep with Modern Standby support
  • Lower power draw and cooler running via 80 PLUS Gold efficiency

Compatible Replacement Unit

This power supply replaces the NEMIC-LAMBDA EWS-50-12 or EWS50-12 in existing systems. It delivers 12 V at 4.4 A for a total of 50 W. The ATX form factor fits the same mounting points as the original unit.

80 PLUS Gold Efficiency

The 80 PLUS Gold certification confirms high efficiency at typical loads. This reduces power consumption and waste heat compared to lower-rated units. Modern Standby compatibility enables faster wake-from-sleep transitions.

Zero RPM Fan Mode

At low and medium loads the cooling fan stops completely for silent operation. Resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine. Lower heat output keeps internal temperatures down during normal use.

Questions about this item

What does the 50 W rating mean for a desktop build?

It means the unit can continuously deliver up to 50 watts of power across its rails, which limits it to very low-power systems such as thin clients or embedded boards.

What does the ATX label tell me about connector compatibility?

ATX indicates the unit uses the standard 24-pin main connector and 4- or 8-pin CPU connector found on most desktop motherboards.

Will this supply fit in a standard ATX case?

Yes, the ATX form factor matches the mounting holes and external dimensions used by typical mid-tower and full-tower cases.
