Ruth's sister 200W Flex ATX power cable

This internal power cable connects a 200W Flex ATX power supply to desktop or server motherboards. It uses a 20 + 4 pin main interface and includes a 4 pin CPU power connector. The unit carries 80 PLUS certification and active PFC for efficient AC to DC conversion.

Builders fitting compact 1U chassis

The cable suits systems that require two SATA ports and two D-type bus connectors for drives or peripherals. It is not for builds needing PCIe graphics power connectors or modular cabling flexibility. Buyers who want more storage connectors or GPU power should look at something else.

20 + 4 pin main interface with 4 pin CPU connector

This fixed pin layout determines motherboard compatibility for the 200W Flex ATX form factor. The non-modular design means all cables are permanently attached to the supply. Verify your board matches these exact connectors before purchase.

Questions about this item

How often should the internal fan be cleaned or replaced in this 200 W Flex ATX unit?

The non-modular design keeps cables fixed, so dust the fan intake during routine case maintenance; no user-replaceable fan interval is published.

Which limit appears first when the 12 V rail runs at full load continuously?

The 12 V output is rated at 10 A, so the current limit is reached before the total 200 W rating.

What noise and heat levels should I expect after hours of operation?

Active PFC and 80 PLUS certification mean typical efficiency above 80 %, reducing waste heat; the small 1U form factor uses a compact fan that will be audible under sustained load.
