L\u2019architecture FPA (Factorized Power Architecture) permet une distribution efficace de l\u2019alimentation et la conversion directe des courants des processeurs, de 48 V \u00e0 moins de 1 V.

Gr\u00e2ce \u00e0 leur bo\u00eetier peu encombrant haute densit\u00e9 (46 x 8 x 2,7 mm) et \u00e0 leurs caract\u00e9ristiques faible bruit, les multiplicateurs de courant modulaires (MCM) sont adapt\u00e9s \u00e0 une co-encapsulation sur le m\u00eame substrat que le XPU, ou juste \u00e0 c\u00f4t\u00e9. La proximit\u00e9 imm\u00e9diate avec le XPU \u00e9limine les pertes de puissance substantielles ainsi que les limitations de bande passante induites par le fameux \u00ab dernier centim\u00e8tre \u00bb parcouru par le courant sur la carte en cas d\u2019utilisation de r\u00e9gulateurs multi-phases 12 V.<\/p>\n
