即係話有80plus 個兩隻火牛 efficiency 較高, 唔洗較大火就可以一樣推得起所有部件, 長遠黎講都可以省點電費. 同時間亦表明買有 80plus 的火牛會有較好的表現. 但火牛的穩定性及耐用程度, 要有甚麼指標及測試呢?

想不到不開機最省電係來自$20的 gtech

cmsdeath

the greatest different is 27W

27W x 24 = 648 Wh

648 x 30 = 19.44 kWh = ~ $19 / month

648 x 365 = 236.52 kWh = ~$230 / year

(max. different only )

cmsdeath

let's consider the idle case , different = 21 W

21 W x 24 h x 365 day = 183.96 kWH ~$180 / year

simple pay back is around 2 year~($360)

for cheap cow upgrade to EA 380

Good Job!!

不過如果可以搵多隻名廠無80+的牛黎比試埋就仲好

點解隻g-tech 會關機0W
而其他用幾W
