Hercules 650W ATX Server Power Supply

This unit is a new 650W ATX server power supply from Hercules. It delivers a maximum output of 650W through a standard 20+4 pin connector and includes a 4-pin 12V connector for CPU power. A single 12cm fan provides cooling inside the 3.5 by 6 by 5.5-inch chassis.

Suits builders fitting a standard ATX server board

It fits systems that need a single 6-pin PCIe connector, three SATA power connectors and three Molex 4-pin connectors. It is not suited for servers that require redundant hot-swap modules, multiple PCIe power connectors or higher total output than 650W.

Key spec: 650W maximum output

The 650W peak rating and the single 6-pin PCIe connector decide whether this unit can power the intended graphics or compute card. Verify that the target component draws within this limit and uses only one 6-pin input before purchasing.

Questions about this item

Should I pick the 650W model or a lower-wattage version for my build?

The unit delivers 650W maximum output, so choose it when your combined CPU and GPU load approaches that figure; a lower-wattage model would leave less headroom for peak demand.

What does the 650W rating mean once the supply is installed in my server?

It represents the total continuous power available across all rails, backed by over-current, over-power and short-circuit protection with 100% full-load burn-in testing.

Which ATX standard does the 20+4-pin connector follow and what does that cap in practice?

The 20+4-pin ATX connector complies with the ATX specification, limiting the main motherboard feed to the pinout and current ratings defined by that standard.
