There's a good chance it is - I have a 2200VA UPS running 2 PCs, 2 Laptops, a 19" LCD monitor, a label printer, three external disk drives, USB network storage server, KVM switch, network switch and a barcode reader... and the UPS reports the load is less than 30% of its capacity, so about 3A.g12net500 said:... i dont think 13a would be enough for 3 computers, network switch, router, printer, monitor and a cooling fan system?
But it does depend on the actual equipment - if your monitor is a 21" CRT and the printer is a colour laser with several output bins, you'd need to do some investigating, but if they are LCD and inkjet respectively, I'd say you're well under 13A all together.
Now I mention it, why not get a UPS? It will give you protection against mains problems while you're using it, and it gives you one turn-off point to thwart inquisitive sprogs! You would need to calculate the load properly, of course, but it's no bad thing knowing that for sure.
Cheers,
