Please recommend UPS for SuSE 8.0 system

My UPS just died and I need a replacement. I don't think I want an exact replacement since I think the old one is under-spec'ed for my system. It was rated at only 185 watts (output) and I now have a 430 watt power supply in my system. Can anyone recommend a good replacement? -- Robert C. Paulsen, Jr. robert@paulsenonline.net
