E-POWER TOP-1100W-PB 1100W ATX 80 Plus Silver Fully Modular Power Supply

SKU CH-Z6ND-3E1PR MPN TOP-1100W-PB

A fully modular 1100 W ATX power supply with 80 Plus Silver efficiency, active PFC, and a 120 mm double ball-bearing fan rated for 40 °C operation

  • TypeATX12V / EPS12V
  • Maximum Power1100 W
  • Fans1
  • PFCActive
  • Main Connector20+4Pin
  • SLISLI Certified
  • 80 PLUS Silver efficiency delivers up to 88% typical load performance
  • Fully modular cables eliminate clutter and improve airflow inside the case
  • 1100 W output supports multi-GPU SLI and CrossFire configurations
  • Japanese primary capacitors and six 12 V rails ensure stable current at 40 °C
  • Thermally controlled 120 mm double ball-bearing fan maintains quiet operation

Capacity and Certification

The E-POWER TOP-1100W-PB delivers 1100 W of continuous power and carries 80 PLUS SILVER certification. It meets ATX12V 2.3 and EPS 2.92 specifications for modern desktop platforms. The unit is designed to support multi-core CPUs and SLI or CrossFire graphics configurations. Full modular cabling lets builders connect only the leads they need.

Interface Practical Limits

Six +12 V rails distribute current for stable operation across heavy loads. Three 8-pin and three 6-pin PCIe connectors provide the maximum native GPU support this unit offers. Efficiency stays above 85 % from 20 % to 100 % load, peaking at 88 % at typical load. Active PFC maintains a power factor above .99 across the 115240 Vac input range. Builders needing more PCIe connectors than six must look elsewhere.

Build Quality and Daily Use

A thermally controlled 120 mm double ball-bearing fan manages cooling at up to 40 °C ambient. Japanese primary capacitors are used on the primary side for longevity. The fully modular design reduces cable clutter and improves case airflow. At 175 mm depth the unit fits standard ATX bays, though tight chassis should be measured first. Safety approvals include CE, CB, TUV, FCC, cUL, CCC and BSMI.

Domande su questo articolo

How do I decide between the available versions or capacities of the TOP-1100W-PB?

The TOP-1100W-PB is offered as a single 1100 W unit in the POWERBIRD series, so there is no version or capacity choice to make.

What does the 1100 W rating mean once the PSU is installed in a system?

It guarantees delivery of the full 1100 W at up to 40 °C operating temperature, with efficiency above 85 % from 20 % to 100 % load and peak efficiency of 88 % at typical load.

What does the ATX12V 2.3 and EPS 2.92 compliance cap in practice?

Compliance with ATX12V 2.3 and EPS 2.92 ensures the 20+4 pin main connector and the six 12 V rails meet current desktop and workstation power-distribution requirements.
