What is EuP?
EuP, stands for Energy Using Product, was a provision regulated by European Union to define the power
consumption for the completed system. With the great quantity and the popularly using of the electrical products
nowadays and the continuously increasing of the electrical products categories in the following 20 to 30 years,
European Union decided to establish an effective strategy to solve the energy consumption problem. That is,
according to EuP, the total AC power of the completed system shall be under 1.00W in off mode condition.
How to setup an EuP system?
To meet EuP standard, the EuP ready motherboard and the EuP ready power supply are required. As a mother-
board vendor with eco-awareness, ASRock is the pioneer to develop “EuP Ready” motherboards based on the
great efforts of our exceptional hardware design.
According to Intel, the EuP ready power supply must meet the standard of 5v standby power efficiency is higher
than 50% under 100 mA current consumption. For EuP ready power supply selection, please check with the
power supply manufacturer for more details.
ASRock, Worldwide First EuP Ready Motherboard Manufacturer!
ASRock hereby proudly announced that we are the Worldwide First motherboard manufacturer to release “EuP
Ready” motherboard to the market! With ASRock “EuP Ready” motherboard, you are confident to setup a system
to pass the EuP standard.

ASRock Instant Flash is an exclusive and the most user-
friendly BIOS flash utility developed by ASRock. It is embed-
ded in Flash ROM which is used to update the system BIOS
without having to enter operating systems like MS-DOS or
Windows.
Once executing ASRock Instant Flash, the utility will automatically detect all devices such as USB, hard
disk or even floppy drive to find the exact BIOS for your system. Instead of giving you all BIOS in your
devices, the Instant Flash just list BIOS versions that apply to your motherboard model only. For
example, if you have many different BIOS of different motherboards saved in your devices, but you just
need to flash your P45 motherboard, the Instant Flash will just list the P45 BIOS versions for you. This
unique function allows you to easily select the suitable BIOS version instead of browsing through all data.
Features
Instant Flash just list BIOS versions
that apply to your motherboard model. Click and start Flashing!
