When I turn off my inverter..usualy its off because its on when I boot normally, I get a frozen computer, is there something I can rig to maybe stop this, or is this not normal?
When I added a cathode to my router project I found that it would reset the machine when switching on/off. The load on the +12V was too much. I remedied this by changing the output smoothing caps in the PSU for a higher value. I wouldnt suggest you do this, but changing the PSU for a different model might help
got a fan controller of any sort? you can ease the power load on the psu by gradually turning the inverter up to full instead of it "jolting" when it turns on/off doesn't seem normal. i run 2 cathodes on the 1 inverter and the 12v line doesn't even fluctuate when i turn them on and off. might be time to invest in a new power supply for the long run though. my lines used to be all over the place. but with my new antec, they are within 2%+/- even when at load and when changing fans from 12v to 7v(putting fans between the 5 and 12v lines to get 7v can be a stress for cheaper PSUs)
Definitely sounds like you need a new power supply. Or you could have a crapily built inverter - something is not right.
Actualy, I just got a new power suply, 480 watt one, the jet black on in the 'quietist psu roundup' can't remember what its called at this moment, but its brand new. Riging up a 4pin-3pin then to my cooldrive 4 so that would work, then slowly turn the nob up?
