I chose a few power supply units. Are they good for cutting off power to USB devices?

My PC currently draws power from Skydigital PS2-500CR 82% ActivePFC v2.31 which is a shitty power supply unit.

 

I want an affordable but decent power supply unit that cuts power to USB devices while the computer is off. I guess I can cut off power to USB devices by enabling 'ErP ready' in UEFI settings. Because I don't play games, my PSU doesn't need a lot of power. I looked for a new PSU and found a few.

  • Micronics Classic II 500W +12V Single Rail 85+
  • Micronics ZERO PLUS 400W Active PFC
    • This looks a bit promising because the power button can be directly wired to PSU instead of the motherboard. Its max efficiency is advertised as 85%, but it doesn't have 80 PLUS certification.
  • FSP HYPER K 500W 80PLUS Standard 230V EU
  • Zalman EcoMax 500W 83+

Do you know a better power supply unit than these?

Man, Skydigital PS2-500CR 82% ActivePFC v2.31 doesn't support 'ErP ready'. The PSU has to support 'ErP ready'.

I thought you were telling me to be quiet. "be quiet" brand is being sold in my region. But, it is beyond my budget. The cheapest model available in my region costs ~137 USD.
