Ruth's sister 600WP internal power cable

Power supply for desktop PCs

This unit delivers a rated 450W with a peak capacity of 600W, intended for desktop computers that use a standard 20+4 pin motherboard connector. It includes an 8-pin CPU connector, two 6+2-pin PCIe connectors, six SATA ports and three IDE connectors for drives and peripherals. The non-modular design means all cables are permanently attached to the housing. Builders who need fully modular cabling or higher continuous wattage should consider other options.

Input range and protection limits

The power supply accepts an AC input between 165V and 265V at 50-60Hz, with active PFC for improved efficiency. It carries 80 PLUS Bronze certification, indicating typical efficiency above 80% at defined loads. Safety features include over-power, short-circuit, over-voltage, under-voltage and over-temperature protection. A replaceable fuse is fitted, and a passive cooling mode can operate the fan silently up to 30% load. Systems requiring a wider input voltage range or a higher efficiency tier cannot be supported by this model.

Build and daily use implications

A 120mm fan provides active cooling, while bulk aluminium Japanese electrolytic capacitors are used internally for durability. The package includes a 1.2M power cord with plug options for EU, US, UK or AU outlets. Fixed cables simplify installation but reduce routing flexibility in compact cases. Users who prefer detachable cables for easier cable management or who need a shorter power cord length will find the supplied configuration fixed.
