Power cable kit for compact builds

This internal power cable set is built for small-form-factor desktops, ITX cases and NAS enclosures where space is tight. It connects a Flex-type PSU to the motherboard, CPU, graphics card and storage drives using short, pre-routed leads. The kit targets builders who need a tidy, single-cable loom instead of loose modular cables.

14-pin to 20+4-pin motherboard interface

The defining connection is a single 14-pin plug on the PSU side that breaks out to a standard 20+4-pin ATX header. If your power supply does not use this exact 14-pin layout the kit will not fit, regardless of wattage or form factor. Verify the PSU pin-out before ordering.

Included 6-pin to 6+2-pin GPU and dual SATA leads

A 6-pin to 6+2-pin cable feeds graphics cards that require an 8-pin PCIe connector. A second lead splits one 4-pin source into two SATA and one legacy IDE plug for drives. The 4+4-pin CPU cable and 14-pin main cable complete the loom so no extra modular cables are needed.

Questions about this item

What does the 500W rating mean when the unit is installed in a system?

The power supply delivers a continuous 500W output and can peak at 600W, with 85% efficiency and low ripple noise under load.

What does the 20+4-pin interface cap in practice?

The 20+4-pin connector follows the Intel ATX 12V 2.31 specification and supplies the motherboard main power rail.

Will the 150+23 by 81.5 by 40 mm dimensions fit my ITX chassis?

The compact 1U form factor measures (150+23)*81.5*40mm and uses a 4020 PWM fan for silent operation in small cases.
