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.
