    Power problems with LV-677DC

    I am having some issues after installing a PCI-E 16x card for dual monitor on my LV-677DC mobo. The system was working fine before this, but i suspect the power cabling being the problem. I m wondering what thickness of cable everyone else is using ? I spoke to Commell and they say that they recommend a 120W ac/dc adapter for my configuration.

    So i am wondering what cable thickness would be acceptable for around 1-2 feet of wiring, right now i am using a 50mm2 (AWG 00 i think its called) from the battery to the distr.block and then i have a quite thin wire, probably 1,5mm2 from the distribution block to the pc, because the connector i am using won't support thicker wiring :-( Also the pc won't boot correctly in the house with my 60W ac/dc adapter, so i am pretty sure its due to cables, but may be someone could shed some light on what they have working ?

    ~30 watt CPU, ~18 watt video card, and a 3.5" hard drive is definitely pushing the limits on that 60 watt adapter. I'd trust Commell on the 120 watt suggestion.

    ya, thats what im thinking and i already ordered a 120W ac/dc adapter for the house, i was more interested in any experiences with actual cabling, and what thickness would be needed to power around 8-9amps peak draw at 13,5 volts which is what i can measure when the car is running.
