I have a Gigabyte GA-H81M-HD3 motherboard and a Corsair 200R case. While connecting the front panel wires to the header, I became confused. For Power LED, my case provides single pin Power LED + and Power LED-. The motherboard seems to have two places to connect these, the standard single pin PLED+ PLED- that I am familiar with, but also PWR_LED+, PWR_LED-, PWR_LED- pins.

The manual reads:
PLED/PWR_LED (Power LED):
Connects to the power status indicator on the chassis front panel. The LED is on when the system is operating. The LED is off when the system is in S3/S4 sleep state or powered off (S5).

with chart:
System Status LED
S0 On
S3/S4/S5 Off


So which should I connect to? I connected to the single PLED+,- and it seems to operate, but am I missing something?

I use that case a lot for office computers and it doesn't come with a cable that is called pwr-led, so corsair probably screwed up on their end. I actually use the 200r for my work pc. I could check it just to double check if you want.

Just looked and when I unplugged the pled+ and - the reset and power led did not work, but when I unplugged the pwr_switch cable it wouldn't come on of course. So in my case the pwr-switch cable turns the system on, but if I leave the pled ones unplugged the led won't come on only the hdd led.

I wonder if the 3-pin connector is the one that supports sleep states. I'm not at home to check my computer, but I have a computer with a case LED for three different states: off, on, blinking. The case LED blinks when the computer is sleeping. If I remember I will check if the connector I'm using is 3-pin. I suspect the 2-pin connector will only show on/off states.
