I am now in the final stage of building my second incar pc. My previous system used a standard PSU and an invertor. I now want a DC-DC power supply for my system but don't really know what I require.
MY System;
Via Epia Pico ITX Motherboard (1024mb ram)
3.5" 160GB Sata HD
I will power my screen from the cars batery though a regulator I already have.
How much power will these draw? I like the look of the M1-ATX 90 Watt Power supply. Is 90 watts enough for my system? Is there any known problems with this power supply (i.e is it any good!).
Any advice/recomendations would be great!
I googled quicky and from what I read, the Pico-ITX Epia board has a single 12v input. how many amps does it draw?
the M1-ATX is not powerful enough for your proposed system. the M1-ATX can provide 2A@12v and 10A@5v. your 3.5" HDD will draw up to 2A by itself which would max out the M1-ATX.
the M2-ATX-HV is the same price and can provide 7A@12v and 6A@5v. it should be able to handle your system with plenty of power to spare.
Whats the difference between a HV and a normal M2 power supply
the reason I suggested the -HV was because it has the same output specs but it costs $15 less (I don't know why the regular M2 costs more...)
