Internal Hard Disk power consumption Tags: Hard Drives Power Consumption Power Storage DeV_88 December 5, 2012 4:27:45 AM Hi ppl, i was trying to choose a new psu to replace my older one. i want to know how much power a single 2tb hard disk requires. For that reason I visited 2 sites. In http://www.extreme.outervision.com/psucalculatorlite.js... i got 17 watt decrease for removing one hard disk. Where http://support.asus.com/powersupply.aspx shows 50 watt change in total amount. And then i visited http://www.wdc.com/global/products/specs/?driveID=1092&... and found 1tb WD cavier blue reqires 6.8 watt. I dont know what is true or i am missing something here. Can anyone tell me how much power HDDs really consumes from a PSU? Thanks in advance. More about : internal hard disk power consumption Can't find your answer ? Ask !
