　一直以來，我玩的東西是都跟耗電有相關的主題，不論是散熱PSU等
就連玩HTPC都免不了要對耗電斤斤計較，不然在散熱跟小型PSU上很難達成
在講求整合及省電的今天，整台主機裡在極度精簡下，剩下最耗電的就是CPU了
借了張ASUS ROG Maximus V Formula，不順便也測一下CPU，這怎麼行(自找麻煩XD)
於是我又去借了幾顆CPU來跑，雖然沒借到i3的東西，測一下i5/i7也作點參考

Test components:
MB : ASUS ROG Maximus V Formula
RAM: AXERIR DDR3 1600 4G*4
SSD: Intel X25-V 40G
PSU: ZIPPY HG2-6400P 400W
Tool: Intel TAT 4.x
Coooler: Intel G530 INBOX Cooler

PS: 作這測試有一部分要作給HTPC玩家作參考，所以我選一顆最矮最容易入手的來測
只是這樣測個有缺點，當TAT開全速跑到100%時，頂到溫度保護就會自動降一點
所以當圖片裡的溫度已經是這顆CPU的保護頂點時，就表示測出來的耗電值不是極值
Idle表示放5分鐘，loading表示所有核心+內顯跑100%到他耗電數字穩定

由於100% loading一般人很難達到，但是需要衡量一下PSU的功率上限是否撐的住
大抵來說，Intel spec上的TDP僅供參考，核心越多越耗電，待機下耗電 T<S<normal<K

補一個個人最愛用的一顆1155 CPU的數據，這顆是之前用B75M-ITX跑的，純亂入
