Replacement 200 W ATX unit

This 200 W ATX power supply is built as a direct replacement for MEGMEET MDP200-4.2-C units. It delivers 40 A on the 4.2 V rail and carries 80 PLUS Gold certification for high efficiency. The unit suits owners of compatible pre-built desktops or small-form-factor systems needing an exact-spec spare.

Fits standard ATX bays and cabling

The supply mounts in any ATX chassis and uses the same connector layout as the original MEGMEET model. Modern Standby compatibility enables rapid wake-from-sleep, while resonant LLC topology with DC-to-DC conversion provides clean power and supports deeper sleep states. Builders must verify that their motherboard and case accept the original form factor and connector arrangement.

Fan and topology features included

Zero RPM fan mode stops the cooling fan completely at low and medium loads for near-silent operation. The resonant LLC design with DC-to-DC conversion reduces coil whine and improves transient response. No extra cables, mounting brackets or software utilities are bundled with this replacement unit.

Questions about this item

Will the 200W limit throttle my system during long sessions?

The unit delivers 200W total; sustained loads near that ceiling will hit the power limit first.

How loud and hot does it get when running all day?

Zero RPM mode stops the fan at low and medium loads; 80 PLUS Gold efficiency keeps waste heat and noise low.

What must my PC already have for this PSU to work?

An ATX motherboard and case, plus cables to reach the 4.2V 40A connector used by MEGMEET units.
