你好，好耐冇入黎啦...
一入黎就有問題了....

基本上想知道桌上型電腦要幾多power 去推既呢？
用手提電腦既電池得唔得？

如果部腦係：
唔需要screen
唔需要harddisk (轉用USB stick)
唔需要ram (內置)
用Mni 底板
有冇可能可以用到手提電腦電池？(2條？)


麻煩哂...過幾日再黎...

零仔, 咁耐無見, 忙緊咩呀? 又搞緊 robot? 閒就去茶舍邊吹下水啦!

你個問題都幾專門喎, 可惜我唔係讀 double e, 唔可以計得好清楚比你知!

但估計 .... 理論上可行的, 用 itx motherboard, atom cpu 的話, 咪同一部netbook 差唔多, netbook 都係用普通 laptop 電!

但你搞錯少少野, 內置 ram 同 usb 都要電o架, 唔好計少呢條數呀!

蛋哥好~~
都係忙緊功課同依個personal project囉~
我都知USB要電，但希望佢相對少於成個harddisk掛....
另外我搵唔到lithium 12V但係over 4~5amp既電池...
因為itx MB 要80W電...

itx 己經係市面上最細同慳電的 motherboard, 如果要再慳電的板, 我諗你要拆舊 laptop 先得啦!

不如搞部舊 10.3" 左右的 laptop / netbook拆黎用啦

how much power a Desktop requires really depend on what kind of system are you refering to
an old Desktop system like 286 may go as low as 50W while a hardcore gaming desktop nowadays may go beyond 1500W
A typical desktop nowadays would probably be around 200-500W
notebook battery is just an electricity storage, you can always use them to power anything as long as you have enough number of batteries to supply the power required

If you are minimizing the power consumption on typical desktop nowadays, u can probably get it down to 80W with mini-ITX motherboard and stuff
I believe mini-ITX motherboard can go below 80W but if you say it requires 80W then let's assume that and do some calculation
mini-ITX motherboard - 80W
CPU if not counting mobile then I believe at best you can only get down to 65W with an Intel Core 2 Duo
if mobile then probably 30W
RAM - one stick ~10W
USB ~5W
Desktop CPU - total ~160W
Mobile CPU - total ~125W

At minimal, i believe mini-ITX can go down to 60W, mobile weaker CPU can probably get down to 15W, RAM can probably find one at 5W, USB 2-3W
then total will probably be ~82W

a typical 12V 4A Lithium battery will have 48W-Hour
but there are many with 14.8V >6600mA (like Toshiba's), which will have ~98W-Hour
In that case, 2 battery ~186W should be able to power ur desktop, or 1 is enough for the minimal system

*I do remember seeing a mini-ITX Case with a 80Watt power supply, so pretty sure there are ways to get desktop run below 80W and one 14.8V >6A battery should be enough for that
