Hi All, My config is AMD 2600+ (barton 512K), ASUS A7N8X-E Deluxe Mobo, 500watts SMPS, 512 MB DDR RAM, ATI Radeon 9600XT DisplayCard, Samsung Samtron 55V (15 inches), Logitech keyboard and mouse. At present, i have 500V UPS(Brand - SBS). Is this ok? Or do I have to replace it with a 800V UPS? Please clarify.
