[HELP] Asus Rampage IV Extreme. USB still ON after shut down

[Sofyan88]

Hi guys.
I'm just purchase an ASUS Rampage IV Extreme.
I Have some question here.

USB power still ON, even when computer is shut down.

may be someone tell me this: "why don't you just cut off the PSU switch button? or directly cut off the head power outlet?"
I DO. but it's still very annoying. come on, this is an era of instant right. this not an era of IBM PC pentium I, pentium II, pentium III or some other old stuff.

I know this is may be the smart feature to charge your mobile device like iPhone or iPod, even when the computer is OFF. but this is really annoying for me, cause I have so many USB Devices like external HDD, USB Modem, external USB fan. etc. and It's not funny to see my USB Devices still working (ON) even the computer is OFF.
at least tell me how to turn off that feature?

I've see the FAQ on ASUS website, and not found anything about my problem.

I've already update the latest BIOS, but still same problem.

I've try to setting all feature on the ACPI Configuration. disable all setting like power on keyboard, power on mouse etc. and still nothing.

can anyone help me?
I hope it's any ASUS guy here where can explain this problem,
at least tell me how to turn off the USB power when the system is off?

Please help me, if any way to solve this preblem.
Thanks in Advance.

Depends how the PSU handles ErP. Up to 1W of power from AC can be supplied in tolerance of ErP spec. Corsair AX range switches off 5VSB with ErP, never tried Seasonic.

Your particular PSU does not switch off the USB power with ErP so there is nothing you can do about it. If it bothers you that much buy another PSU that does.

I had my Razer Black Widow occasionally stay light up after shutdwon, thats how ive found this, but ERP is not that ideal when overcloked. For me it cold boots twice if multi set higher than 43x ; (

See answer on your thread on why that happens:)

i have the same probleme anybody find the problem ?????

[Raja]

Problem is how PSU support ErP. If your PSU supports it like Corsair AX1200, then enable ErP in APM section of UEFI to turn off 5VSB to USB.

ok if i understand if my psu dont support the erp mode my usb still on after shuntdown

i have a antec tpq-1200 and with the erp enable or not my usb is on
