Hi, i am currently trying to build a $300 htpc. I have seen 2 models which seem like they would do the work i need in another post.

Intel Solution:

Intel Pentium Dual-Core Processor G630 2.7GHz 3MB LGA1155 CPU
ASRock H61M/U3S3 LGA 1155 Intel H61 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel Motherboard

Amd Solution:

AMD A4-3400 Llano 2.7GHz Socket FM1 65W Dual-Core
ASRock A55M-HVS FM1 AMD A55 (Hudson D2) HDMI Micro ATX AMD Motherboard

Issues

I need a MINI ITX solution, so i will be exchanging those Motherboards for a similar miniitx form factor. My main problem has been finding a case and psu.

How many watts would a system like this need? i would plan on connecting maybe a usb hd dvb-t tuner, no cd/dvd, 2.5 or 3.5 normal hdd (not ssd). Most cases come with sub 120W psu, which according to what i read before, is not enough for any htpc, tho i may be mistaken.

I have seen some cases that say 120watts DC to DC + Adaptor... What exactly is this? would this really be enough for the systems i mention?

other mention pico psu compatible, i dont know much about picopsus, but could they possible provide enough power for one of the systems i mention?

thanks for reading! please help!

I was just checking my recent HTPC build with a G620, ECS H61 mobo and an OTA dual tuner card.

Recording 2 OTA HD programs & playing a 3rd previously recorded HD program my Kill A Watt meter indicated a pretty steady 42 watts. IIRC it did peak to 70 watts when first powered on, but that was a real brief peak.
