Supersuperuncle 600W 2U Server Power Supply EFAP-552

SKU CH-2JH4-PJN8M

2U server power supply delivering 600W to replace Great Wall and Etasis R520 G4 units

  • 600 W output powers demanding 2U server builds
  • Replaces Etasis R520 G4 550 W unit directly
  • EFAP-552 form factor fits standard 2U chassis
  • New condition ensures full service life ahead

Direct Replacement for Etasis R520 G4

This 600 W server power supply is built as a direct replacement for the Etasis R520 G4 2U 550 W unit. It fits 2U rackmount chassis and delivers the power needed for continuous server operation. System integrators and IT teams maintaining existing Great Wall or Etasis deployments can install it without modifying the rack infrastructure.

Upgrade When the Original Unit Fails

The supply replaces a 550 W model with a 600 W rating, providing extra headroom for configurations that have grown beyond the original spec. The jump is worth it when the existing PSU has reached end of life or when added drives and cards push the load past 550 W. Buyers needing redundant or hot-swap capability should look elsewhere, as this unit is a single fixed supply.

Highlights

  • Replaces Etasis R520 G4 550 W unit directly

Questions about this item

Will the EFAP-552 fit in a standard 2U server chassis?

The unit is built to the 2U form factor, so it aligns with standard 2U server rails and mounting holes.

What is the correct way to seat the EFAP-552 power supply and what step is often missed?

Slide the supply fully into the bay until the latch clicks, then tighten the retention thumbscrew; skipping the screw leaves the unit loose and can break contact.
