    I was looking for an LED strip for a project I'm working on, and I ended up picking up a couple of these flexible light bars. It wasn't until I actually got them that I started thinking about how I was going to power them. In retrospect, I should have just picked up something more suitable from a modding site. Anyway, the suggested method of powering these is using one of these 12V power supplies with a two pin adapter. However, I want to use the light bars in a mod project, and I don't really want to have to deal with another power cable just for the LEDs. So was wondering how reasonable it would be to wire something like this to a 4-pin connector, or if that would even work. Am I missing something obvious here, or are these light bars just not meant to be used by noobs?

    Theoretically you could just wire it up to the 12v and ground on a molex and it'd work, but I'm rubbish with electronics so if you want a circuit diagram ask someone else:p

    It should work just fine off a Molex connector.

    The spec for them says 12v DC, so that's the Yellow and Black wires in a Molex (Yellow=+12v and Black=0v).

    Not had a good look, but I really can't imagine how it would overpower even the weakest PSU, unless you buck todays trend for massive overspec of your systems PSU.

    Yeah, I think I'm going to give that a shot. The strips have a two-pin connector for every three LEDs, so you can cut it into three-LED sections. I can try this for one section, and if it doesn't work I'll just be out one section. Thanks.
