A NEW WAY TO MEA­SURE AND RANK PSU EF­FI­CIENCY

PCPOWERPLAY - - Tech Bytes -

You know those 80 Plus rat­ings on power sup­plies that are sup­posed to let you know how ef­fi­cient they are? There’s now an al­ter­na­tive rat­ing scheme from a com­pany called Cy­be­net­ics called ETA and LAMDA that they say of­fer greater ac­cu­racy than the 80 Plus rat­ings we’ve come to know and love. The ETA rat­ing mea­sures power ef­fi­ciency via “a unique, cus­tom-made ap­pli­ca­tion to ac­count for the ef­fi­ciency re­sults of thou­sands of dif­fer­ent load com­bi­na­tions through a unique pro­pri­etary ap­pli­ca­tion” and as­signs a rat­ing of A+ for the most ef­fi­cient and D for the power sup­plies least ef­fi­cient. LAMDA cer­ti­fi­ca­tion tests for noise lev­els - the qui­etest of PSUs gets an A++, with noisy clunkers get­ting an E. Re­spected power sup­ply man­u­fac­turer Sea­sonic is al­ready on-board, em­brac­ing the ETA and LAMDA rat­ings for its flag­ship Prime units.
