今日換左條好啲usb線。。立即覺得畫面再sharp左好多
想問大家9702 12v版 如果 其實用埋audio out （唔需要u ...

9702v3 12v dc in 不需要usb 供電給hdd, 平均大約dc 12v 0.6a

唔該師兄
我諗我個 Lps 3.5ma 應該夠同時比 hdd (ssd) (佢寫2ma) 同970

12v 3a(持續恆定輸出電流) 足夠9702 + 單3.5" hdd 供電

12v dc 供電除了LPS外, 還有電池供電, 以下依款用超級電容對於高要求岩晒, 可以充電/放電數百萬次, 價錢也合理

The output voltage regulators—previously a cascade of the very fine (4.2µV/RMS noise) Texas Instruments TPS7A4700—have been changed to the truly extraordinary (0.8µV/RMS!) Linear Technology LT3045—a pair of them paralleled in a configuration that further lowers output impedance.  We are down into the 3mOhm (10Hz-100KHz) range now!

有冇人試過水電？得唔得（有冇改善）？
