the video card i ordered requires a min. of 250watts of power and i looked at my psu and it said it had a max. power output of 250watts. its not going to fry my computer is it.

Here try calculating with this: http://www.jscustompcs.com/power_supply/ It will either work, not work (not turn on), or work and turn off in full load times (i.e. playing a game). None of this will damage your PC though, hopefully :) Radeon 9800 Pro 128Mb AMD Barton 2800 Asus A7N8X E-Deluxe 512 DDRAM PC2700

Or it will fire mains voltage through your entire system possibly causing a major fire, get a decent psu Q-TEC 550 Watt PSU MSI VIA KT4AV-L 2800+ Barton 512 DDR333 GeForce4 Ti 4200 128Mb Aero 7 Lite 80Gb Samsung ATA133 HDD 120Gb WD ATA100 HDD LiteOn LDW-851S LiteOn LTR-52246S

Yeah, get a new PSU. 25ow just isn't going to cut it nowadays. AMD Athlon XP 1800+ Geforce 3 512MB DDR266 RAM 250W PSU 56X CD-ROM 52x24x52 Samsung CD-RW 20 GB Maxtor HDD 80 GB Hitachi HDD Gigabyte GA-7DX+ MOBO SMC 10/100 LAN

If you only have 250 and the graphics card alone requires 250, then how will you power the hard drive, motherboard, sound card, fans, etc? Sorry be being a smart-a$$, but the answer is obviously No. A new PC with gaming-oriented components is probably going to need 400 - 500+ watts. Best Luck, Bob
