Motherboard Led's won't turn off when I turn off the computer Asus x-99 Pro ERP settings

Hello Everyone

Here is the rundown of my issue my computer works great and has been for a year and half with no issues. I just installed a USB 2.0 memory card reader and the green led shows up for that. No problems with my motherboard or any of my other other hardware.

I have read online about people's Led's staying on their motherboards and it has to do with the enabling the ERP settings in the advanced settings in the bios. Enabling ERP settings turns off the extra power that keeps on the LED's on the Motherboard and memory card reader.

I have two options for ERP settings and I don't know what is the safest bet thank you?

Option One: Enable (S4+S5)

Option Two Enbale (S5)

Bump does anyone have a solid answer on this. Also my power supply is Corsair, HX850i is that a requirement for ERP?
