Hi
I have just built a small CCTV computer using the Geovison GV-650 (nice work if you can get it BTW) for a customer and its all set up and working fine. I had explained to the customer that if the mains power failed the computer would obviously shutdown and no loner would be recording the CCTV footage. I had suggested something like an APC 1000 which would give about an hours grace if the monitor was excluded.
He asked me “but what after an hour there is still no power and there is no one around to switch it back on?" Now that’s a good point. I said that there are better products that would hold a longer charge but would obviously start costing a lot more especially with replacement batteries ect later on.
He didn't like the sound of "cost more money" so I said I would look into a solution. Stupidly he does not mind if he looses some CCTV time just as long as the pc turns on again when the power is back that’s fine, but hey what ever the customer wants.
So I was thinking would it be ok just to put a short over the green and black cable of the PSU. It’s what I usually do if I need to quickly test something like a fan or open a CD drive with a spare PSU. In theory it should be ok but it would be nice to see if any one has ay better Ideas.
Also I have seen PSUs with a stated 85% efficiency I've never been that bothered to find out but as I'm here what is the efficiency of these presumed lower quality PSUs?
Thanks for looking
