Have a 256 MB Nvidia FX 5500 and would like to overclock it, but can my PSU handle it? This is what I got: (nothing overclocked) *Soltek SL-865Pro2-FGR *Intel P4 2.80E Ghz HT w/800Mhz FSB 1MB L2 Cache 1.4V max *aformentioned AGP video card *Nvidia GeForce 2 MX PCI 32MB *Creative PC-DVD Encore *Creative SoundBlaster PCI *Lucent 56K PCI Modem Powersource is a LC-B500E by L&C Computing, total output is 500W Max. Also written on the label is +5V & 3.3V & +12V load is 422W. Connected peripherals are 2 optical drives, 1 SATA, 3 IDE, a Musketeer 2, floppy, and a Vantec HDD swapper thing. 3 80mm fans connected directly to the connectors, one connected to the mobo, and 1 from the psu connected to the mobo. How can I find the total output my computer is using, and how can I increase my agp cards' performance without blowing it and everything else up?

IMO your video card will most likely bite the dust before your PSU ever buckles from an overclock of the card. Here is a simple wattage calculator for your PSU just to give you an idea. -- Have a Happy New Year --

If you wanna OC your nVIDIA card, you should download coolbits. Check out the following string: http://www.computing.net/cpus/wwwboard/forum/10325.html

thanks to both of you. I looked at the first link, they didn't have the FX 5500 so I used the FX 5600. Apparently I have about 431 watts used. My motherboard's BIOS allows me to increase the voltage to the AGP slot to any of the following: 1.5, 1.6, 1.7, & 1.8 volts. So now I have two more questions: what would be a formula to calculate volts to watts, and what effect would increasing the voltage to the AGP slot have? (faster ramdac, etc.) I'm looking into the Coolbits thing, but I would like to know the effects of the AGP voltage for future reference. Thanks for your help!
