Reply With QuoteI cant imagine the PSU spiking to over 300w, but try this - unplug the computer from the inverter.
turn on the inverter, and wait 3 or 4 seconds, then plug in the PSU. (aka, give the inverter time to warm up)
Hi,
Im trying to get my PC fired up in my car, but it just wont spark to life..
Im using an epia M10k nehemia with just 1 disk, 1 USB GPS mouse, and a PSU powered 10watt Screen.
My converter is a 300w cont. 1000w spike.
Its got "Softstart".
When I initiate power to the PC, both the converter and PSU start making klicking noises. Like one of those electrospark kitchen stoves.
I think the whole deal gets crammed because of that softstart gismo... Perhaps it doesnt produce enough of a jolt to spike the PSU to go into action.
Someone formiliour with this annoying misshap?

connect the inverter using heavy gauge wire to the battery directly. (Not through the lighter socket)

Ive tried the warming up, but the inverter seems to just drain straight away.
I used kingsize wire to connect straight to the battery, theres a flickswitch in between though, could that pinch the flow that much??
well, the switch has a current rating , but it would have to be really small to mess things up.
The unit does run off house power ok, right ?
Might be that the PSU might not like the "modified sine wave" (stair step wave) that the inverter is feeding it. You might try a different brand of inverter or different psu if you can. Also, what does "Kingsize" wire qualify as? 10ga? 8ga? I've got a M9000 with an old desktop hd and a bunch of peripherals with a 200w 1u psu that spikes to ~150w when the pc first starts. You might look also at the inrush current for the psu, which is what the psu breifly draws as it energizes.

What about a condensator and a start-up delay. The condensatot will bring a continous power to the inverter and the start-up delay wil start the PC after the engine is started and the condensator is powered up.
System in progress:
New install in progress...
i think that the condensator thing should be a good solution Freakazoid... maybe it could give just that burst to start up...
and a condensator is much cheaper than a other converter.. so try the cond. first..

Not trying to be picky, but to clarify for others that may be reading - I think your refering to a capacitor.
I think mp3dub's theory is most likely the answer.
The only way the capacitor would help, is if the cars electrical system is having trouble supplying the inverter power during the startup.
A capacitor rated for this use would run around 100.00 USD
I would try exploring other options first.
A DC-DC supply would solve the problem - the good ones go for around 150. I had several conversations with audioforge about his pw120 product (53.00), but im not going to pass judgment till I can get my hands on it and put a volt meter to it.
When I was building my car computer I had to go through about 4 ATX power supplies before I found one that would work with my inverter seems like diffrent power supplies are very picky about their power. Of course the cheapest power supply works the best and thats running an AMD XP 1800+ and the LCD and I only have a 300 Watt inverter.
