I'm upgrading my system, and I would appreciate recommendations for a power supply to meet my needs. The system is a I7 920 2.66 GHz with 6GB of memory, 3 HDs (2 high speed), 2 DVD drives, a high-end graphics card running off a 850W PS. I also have a 24" LCD display, 2.0 speakers, a cable modem, and a wireless router I want to put on the UPS.
My old system was running on a APC Back-UPS LS 500. Will my new configuration be too much for it? If so, what would be a good product?
