Stacionarus ... MSI H81 matke su Pentium G3420 

Del W matavimo - Gigabyte panasiai kaip MSI.. AIDA64 idle CPU_Package duoda ~10W (gal taip ir yra).

Keli testai su elektros [riebumo] matuokliu (PSU 250W 80plus_bronze FSP).
OFF - ~11W / BIOS - ~53W / Win7_idle - ~35W
AIDA64_ CPU_package / IA Cores / GT Cores:
Win7_idle: ~35W is 230V ... AIDA64: 10,78 / 0,63 / 0,44

Control Panel > CPU Power Max ribojimai:
AIDA64_ CPU_package / IA Cores / GT Cores:
Win7_idle: -------------------- ~35W is 230V ... AIDA64: 10,78 / 0,63 / 0,44
20% = 0,8GHz -- FPU_stress: ~39W is 230V ... AIDA64: 14,52 / 4,39 / 0,49
50% = 1,6GHz -- FPU_stress: ~44W is 230V ... AIDA64: 19,60 / 9,84 / 0,44
75% = 2,4GHz -- FPU_stress: ~51W is 230V ... AIDA64: 28,80 / 18,44 / 0,57
100% = 3,2GHz-  FPU_stress: ~62W is 230V ... AIDA64: 40,33 / 29,72 / 0,60

Matavimai tokie salyginiai, nes tas buitinis elektros matuoklis kartais sokineja su PF ir W tampa "idomus".
Kas gan idomu, kad downclock'intas CPU tampa gan mazai elektros edanciu CPU:
( prie 50% galios - 3X maziau W [9,7W vs 29,7W], prie 25% galios - 6X-7X [vos 4,4W vs 29,7W] )
Tik neimt visiskai tiesiogiai, nes CPU_package = susumavus RAM kontrolerio, PCI-E kontrolerio, CPU_cache_maitinimo 
ir kitus proco reikalus, gauname, kad... 50% 19,6W vs 100% 40,33W (CPU_package)...
Bet jis ir ant Idle rodo ~10,8W .... tai 50% + ~9W ... o 100% + ~30W <<< 2X leciau, 3X taupiau...
