I was about to create a new thread but used the search instead and decided to post my question to this thread. Hopefully it is ok.
I am planning to buy a PC case which comes with a 60W power supply. I don't know yet the current values of the DC board for the different voltage levels. I think the AC/DC brick is a 60W / 12V.
I was wondering what might be the power requirement difference between a setup with one DVB tuner product in PCI bus and a setup with two DVB tuner products using PCI bus.
Do you guys have any estimates on this. Basically I am hoping to find out that how much a PCI bus DVB tuner product requires power?
Is it so that mostly the PCI bus product loads the 5V and 3,3V lines (or only one of these?) and no 12V at all?
I think the Atom330 based setup would pretty much be on the limits of the PSU section and I would like to try to be sure that the line is not crossed.
I used to have a DVB card when I was living in Europe and I do not know the exact power consumption but it was getting quite hot so I will say that it will be a minimum of 3W and a max of 6W and is true that they use the 5V line and some times the 3.3V but not the 12V line.
From my knowledge there is only a PCI on Atom boards so you can only use one and you will be fine I think with the 60W power supply.
If you need a second DVB you can use an USB one or even two and in this case if the 5V line will be to stressed you ca use a powered hub to solve the problem and a 2.5" HDD will be a good choice.
One more thing to consider is using an ION based Atom board the Intel chipset will not be able to play 1080p i guess. My old setup was a Athlon XP 1800+ with a GF 5200 and a Skystar 2 DVB-S on PCI and was able to play the 720p channels but the 1080p was just a slide show.
