DESCRIPTION
VRK81B080CU is designed to meet the fast load
transients required by AMD 64-bit processors
and is fully compliant with the latest AMD64™
processor power specifi cations. Packaged in a
compact design, VRK81B080CU has a height only
1.16” (1.2” total mating height), and is ideal for
1U server applications. High effi ciency of 85% at
full load for reduced power dissipation to simplify
system thermal management.
