  • Zero RPM fan mode keeps operation silent at low loads
  • LLC resonant topology with DC-to-DC conversion delivers clean, stable power

Compatible Dell and HP models

This power supply fits Dell workstations including the 3080, 5080, 7080, 7070, 3990 and 3881. It provides a standard ATX form factor with a 6-pin connector for direct replacement in these systems.

Thermals and acoustics

An 80 PLUS Gold rating ensures high efficiency, which reduces waste heat and keeps temperatures lower during normal loads. A Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation, while the LLC resonant topology with DC-to-DC conversion minimises coil whine.

Modern Standby and power delivery

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and supports more energy-efficient sleep states for the connected workstation.

Questions about this item

How do I install this ATX power supply and which step do builders often miss?

Mount the unit in the case with four screws, connect the 24-pin ATX, 8-pin CPU, and the 6-pin connectors listed for models 3080 5080 7080 7070 3990 3881, then switch the rear I/O toggle on before pressing the case power button.

What maintenance will this 260 W Gold unit need later?

Vacuum dust from the intake grill every six to twelve months; the Zero RPM fan mode means the fan spins only under load, so bearings last longer and no lubrication is required.

What limit appears first when this 260 W supply runs at sustained load?

The 260 W total output ceiling is reached before thermal limits, so the unit will trigger over-power protection if continuous draw exceeds that rating.
