Power supply for mainstream builds

The TOPOWER TOP-500DB delivers 500 W from a single 12 cm fan unit measuring 150 x 140 x 86 mm. It suits standard ATX or EPS12V systems that need a straightforward, non-modular power source without extra cable management. Builders who want more output or fully modular cabling should look elsewhere.

Dual 6+2-pin PCIe connectors

Two 6+2-pin PCIe cables provide the only native graphics power on this unit. A card that demands three such connectors or a single 12-pin plug cannot be powered without adapters, which adds clutter and risk. The fixed cable set also includes six SATA connectors and a 20+4-pin main plug.

Fixed cables mean planning ahead

Because the loom is not modular, every lead stays in the case whether used or not. Route the 140 mm deep housing first, then dress the 20+4-pin, PCIe and SATA runs before closing the side panel. Active PFC handles 100-240 V input at 47-63 Hz, so no voltage switch is needed.
