Keeping in mind this is a pretty empty box that's pretty sleepy until I hit compile doing FPGA/SoC development. (i.e. no power hungry graphics cards -- it's a home file server more than a desktop) Here's them power numbers -- all of the drives are listed as peak (as in start up) where average was much less... but using those hypothetically as worst case: They still don't touch the supply rails even after considering fans (which spin at very low PWM duty cycles) (not sure this table will print -- let me know if it doesn't) *_Model:_* *_Wattage_* *_+5V_* *_+12V_* *_+3.3V_* *_5V StdBy_* PWS-652-2H 650W 30A 54A 20A 4A Slot 1 WD2500AAJS 21.24 1.77 N/A N/A Slot 2 WD10EZEX 30 2.5 N/A N/A Slot 3 ST1000DM005 24 2 N/A N/A Slot 4 HD103SJ 36.4 2 2.2 N/A N/A Slot 5 WD10EFRX-68F 14.4 1.2 N/A N/A Slot 6 HD103SJ 36.4 2 2.2 N/A N/A Slot 7 WD10EFRX-68F 14.4 1.2 N/A N/A Slot 8 WD10EFRX-68F 14.4 1.2 N/A N/A Slot 9 Empty N/A N/A Slot 10 Empty N/A N/A Slot 11 WD10JFCX-68N 5 1 0 N/A N/A Slot 12 WD10JFCX-68N 5 1 0 N/A N/A *Totals:* *201.24* *6* *14.27* -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
