Flex ATX 300 W internal power cable

This cable set connects a Flex ATX power supply to an ITX or 1U desktop or server build. It delivers the 20+4 pin motherboard, CPU, graphics and SATA leads required for a compact system. Builders working with small-form-factor chassis will find the full-modular design useful.

Practical limits of the Flex ATX interface

The 20+4 pin main connector, single 4-pin CPU lead and one 6-pin to 6+2 pin GPU lead restrict the platform to boards and cards that fit those plugs. Only two SATA ports are provided, so additional drives need a different power source. The 12 V rail is rated for 200 W, capping total graphics and CPU draw.

300 W rated output decides suitability

At 300 W continuous and 400 W peak, this unit suits low-power ITX or 1U servers but cannot support high-wattage CPUs or discrete cards that exceed the 12 V 200 W limit. Buyers needing more 12 V current or extra SATA connectors should choose a higher-capacity supply.

Questions about this item

Should I pick the 300 W or 350 W version of this Flex ATX supply?

Only the 300 W model is listed; it delivers a rated 300 W with a peak above 400 W.

What does the 300 W rating actually power inside my ITX build?

The 12 V rail supplies 200 W for the CPU and GPU, while the full unit handles 300 W continuous load.

How does the 20+4 pin ATX connector limit what motherboards I can use?

The 20+4 pin interface fits standard ATX motherboards, and the 18 cm lead reaches most ITX layouts.
