ATX power supply for modern standby systems

This ATX switching power supply delivers 2880 W at 53.5 V and 50 A for builds that require high-output DC power. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. The resonant LLC topology with DC-to-DC conversion supplies clean power and reduces coil whine.

Fits standard ATX layouts

The unit mounts in any ATX-compatible chassis and draws AC input to produce a single 48 V DC rail. Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running. High efficiency lowers waste heat, easing thermal demands on surrounding components.

Replaces lower-efficiency

Builders upgrading from supplies without Gold-rated efficiency or semi-passive cooling gain quieter operation and reduced energy draw. The jump is worthwhile when a system needs 2880 W of stable 48 V power and benefits from Modern Standby sleep states. Units lacking resonant LLC topology cannot match the same power quality.

Questions about this item

What happens when the 2880 W unit runs at full 50 A output for long periods?

The 80 PLUS Gold rating keeps efficiency high so less waste heat is produced, and the resonant LLC topology with DC-to-DC conversion delivers clean power without coil whine even under sustained load.

How loud is the fan during all-day operation?

Zero RPM Fan Mode stops the fan completely at low and medium loads for near-silent running; the fan only spins when thermal sensors demand extra cooling at higher loads.

What motherboard power connector does this ATX supply need to function?

It requires a standard 24-pin ATX main connector plus the appropriate 8-pin or 4+4-pin CPU power cable from the motherboard to deliver the 53.5 V rail.
