Main HTPC has AMD A4-5300 with 8GB dual channel memory and tv tuner card. Has bluray/dvd rewriter. 2TB hdd for movies and 2TB hdd for TV series. 1TB hdd for OS and document backups and 500GB hdd for tv recordings. 500GB 2.5inch HDD with OS. Using wall power meter at idle it uses 20watt and 50 watts watching video from internal hdd using xbmc. On startup it does spike to 65 watts.
As I have home server with all files on and those all backed up to another NAS I thought would put together what I thought would be low power htpc client using some parts already had.
I have Antec isk110 case with mini itx motherboard AMD A4-4000 cpu. 4GB single memory and 120GB Crucial SSD. Again this idles at 20watts and 45 watt streaming a movie from server.
Using Windows 7 64bit. home premium on this and Windows 8 pro on the main htpc. So a little dissapointed as thought with only 1 drive being ssd it would use a lot less power. Seems only real advantage is small unit taking up less space.
I could have gone with Intel NUC but thought later on wouldnt be able to upgrade motherboard etc and would have to buy whole unit. But probably would have been better in long run with this power consumption.
