Purpose and Audience

The Darkside DS-0819 is a 30cm internal power Y-cable that splits a single 4-pin Molex connector into two 3-pin fan headers. It is intended for PC builders who need to run two 3-pin fans from one Molex output on a power supply. The cable carries only the 12V feed wires, delivering fixed full-speed power to attached fans.

Who This Suits and Who It Does Not

This cable suits builders adding case fans to a system with spare Molex connectors and no remaining motherboard fan headers. It is not for users who need PWM speed control, voltage regulation or a 5V supply line for 3-pin devices that require lower voltage. Buyers wanting fan-speed management should look at a motherboard header or a dedicated fan controller instead.

Deciding Specification

The critical detail is that the cable provides only a 12V feed to the two 3-pin connectors. Because the 5V and ground regulation wires are absent, every connected fan will run at its maximum rated speed continuously. Confirm that your fans are designed for constant 12V operation before purchasing.

Questions about this item

What connectors does the DS-0819 Y-cable include and is anything else needed?

The cable has one 4-pin Molex plug with a passthrough and two 3-pin fan headers; no extra parts are required.

How do I pick the right version or length of this Molex-to-dual-3-pin cable?

Only one version exists — model DS-0819, 30 cm long, black, carrying 12 V only.

What does the 12 V rating mean when I plug two fans into this cable?

Both 3-pin headers receive a straight 12 V supply from the Molex source, so connected fans run at full speed.
