1300W ATX/EPS power supply

The TOPOWER TOP-1300W delivers 1300 W from a single +12 V rail rated at 108 A. It targets builders who need dense GPU power for six-card mining rigs, multi-GPU gaming setups or server workloads. The unit accepts 100 – 240 V input at 47 – 63 Hz and includes active power factor correction.

85 % baseline efficiency with 230 V gains

Stated efficiency exceeds 85 % overall, reaching a typical 87 % at 115 V and 90 % at 230 V under load. The fixed cable set provides twelve 6+2-pin PCIe connectors, eight SATA plugs and a 20+4-pin main connector. No modular option is offered, so unused cables remain in the case.

Non-modular install with twelve PCIe leads

Installation means routing the full loom of twelve PCIe cables plus eight SATA lines even if only a few are used. The single 135 mm fan handles cooling, but the fixed harness can crowd tight chassis or custom loops. Over-voltage and overload protection are built in.
