Hi Everyone.

I've been able to get my hands on a few server PSU's. See photo.

As I'm am absolute newbie I have no idea how I can use these.

How many pixel strips can I power with these? And how do I connect them?

Cheers

If I read right it says 12V 71A. Pixels are 55mA at 100% white so in theory you can run 1290 pixels from it.
No idea if matches what you have but @Cranzy had a server power supply and below info was for his.
1) Pins to short for power on - (top row 5th from left, bottom row 4th from left)
2) Pins for Voltage(-) - Blue
3) Pins for Voltage(+) - Red

Hi Alan

How many strips does that make it? When you say pixels, is that the same as leds?

Unfortunately they are all at work but I recall them looking similar to the one pictured.

What connections do I need?

Thanks

I hope that leds and pixels aren't the same thing. 12V nodes are 1 led per pixel and there's massive amounts of heat that gets generated as they dump the excess voltage. 12V strip is 3 leds per pixel.
There is a variation to the 55mA per pixel which is the norm for WS2811, WS2812 and all the equivalents. The GS2808 is a 12V pixel and 1 rgb led per pixel but is only 18.5mA. That would mean you could control close to 4000 pixels from each power supply.
I know nothing about the connectors or power supplies. At some stage in my leisure time I'm going to do a pcb for @Cranzy but it hasn't happened yet.
