EuP Ready Motherboard
EuP Ready Power Supply
EuP System
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.
ASRock, Worldwide First EuP Ready Motherboard Manufacturer!
To meet EuP standard, the EuP ready motherboard and the EuP ready power supply are required. As a motherboard vendor with eco-awareness, ASRock is the pioneer to develop “EuP Ready” motherboards based on the
great efforts of our exceptional hardware design.

ASRock Instant Flash
ASRock Instant Flash is an exclusive and the most userfriendly BIOS flash utility developed by ASRock. It is embedded in Flash ROM which is used to update the system BIOS
without having to enter operating systems like MS-DOS or
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.
