Case LEDs help

[mjrand]

I have a LianLi PC60 Case and an Intel D850EMV2 motherboard. Building my first comp ever. All thats left is hooking up the case LEDs to the motherboard. I've run into a slight problem though. According to my motherboard manual, each LED should cover 2 pins. Some of mine cover 3 and 4 pins like speaker and power led. Also the motherboard manual only mentions about some of the case LEDs. Some don't exist in the manual.

Case LEDs: Power SW, Speaker, Power LED, HD LED, Reset
Motherboard Manual: Power LED, HD LED, Reset, Ground, +5V

How come some of these don't match up? Even of the ones that do, according to the motherboard should only cover 2 pins, but they seem to cover more than 2 pins. What's going on here?

Thanks for any help you can give.

Sometimes connectors simply won't fit (for instance 2 pin vs 3 pin power LED's), or there are extra ones (unsupported on motherboard, maybe a SLEEP/STANDBY etc.) ... just plug-in what you can (at least HDD, POWER and RESET) ... also, you can crimp unmatching connectors if you feel like (I did this last time with 3 pin power-led case connector in order to fit 2 pin motherboard's connector).

Sometimes orientation of pin1 matters, sometimes not, check your mb manual... in general you won't screw up if you put it wrong way, it just won't work until you correct it.

good luck

according to the Intel specification for the D850EMV2 here are the following connections. I list them as your case labels them:

Power SW pin 6 pin 8 (polarity is not important)
Speaker no output - the specification states that there is a speaker hard soldered to the motherboard
Power LED pin 16 (+) pin 12 (-)
HD LED pin 1 (+) pini 3 (-)
Reset pin 5 pin 7 (polarity is not important)

To determine which wire is the negative (-) on a connector look at all of the Case LED wires. The negative wire is identified by color, either black or white. Each case manufacturer does it differntly. If all of the connectors have at one black wire, then the black wire is negative. If all of the connectors have one white wire, then the white wires are the negative. The other wires going into the connectors are usually colored.
