I am building a folding rig that will be stationed at my wellsite trailer/office. There may be the occasional unplanned power outages so what I am looking for is recommendations for an auto shutdown routine and a UPS. Naturally, the UPS must have the capacity to accomplish the auto shutdown routine. Easy and economical replacement of batteries would be a huge plus also. The rig will consist of I7 oc'd, 2 x 470, 1x 460, hdd, yada, yada, and would need to shutdown from 3 x gpu folding clients and a cpu folding client. I have no experience with UPS or auto shutdown programs for that matter, not sure if it is even possible, and any recommendations would be greatly appreciated.
