Not the store. A Universal Power Supply. Or, so as not to confuse the Best Buy help, a Battery Backup.

Since Best Buy doesn't carry one that's good enough, I need to search online. But since I'm not too UPS savvy, I thought I'd ask.

I need a UPS to back up the Silver Hammer (dual 5970s in Crossfire, one HDD, one optical drive, AMDx6 1090T, HAF 932 case). I have a gold rated 1000W PSU running everything, and it runs well. I just need the backup.

I'd like something adequate to back that up (my 750W UPS is insufficient). Any thoughts/feedback would be appreciated...
