Will I have to get a new power supply for this graphics card?

My computer is an HP Pavilion a6110n.(250watt PSU)

Its specs are:

鈥?AMD Athlon 64 X2 Dual-Core Processor 4400+ with Enhanced Virus Protection鈥?br> 鈥?512KB x 2 L2 cache

鈥?2000MT/s frontside bus

鈥?2.0GB of DDR2 SDRAM

鈥?320GB 7200-rpm Serial ATA (SATA) hard drive

鈥?LightScribe SuperMulti DVD drive (reads/writes DVD卤R/RW, DVD-RAM, CD-R/RW)

鈥?nVidia GeForce 6150 SE Graphics

I want to buy an nVidia 8800GT, will I have to buy a new power supply as well? I believe I will but want to double check this.

You will need a PSU with at least 400watts and 26amps on its +12V rails if you plan to run an 8800GT. A lot of video card upgrades include a bigger PSU. You will be seriously underpowering your whole system which will result in random reboots, hardware failure and your 8800GT will run like crap because it won't be running at 100% efficiently.

I run a Dual Extreme clocked at 3.2, 2 WD Raptors in Raid0, a third storage drive, 4GBs of XMS ram, an insanely overclocked G92 8800GTS, a Creative Sound card, 2 DVD Rom drives, a floppy drive, ATI TV tuner, 9 fans including LEDs and a 92mm Vantec Tornado cpu fan that draws 13.5 watts and 2 UV tubes with a 550watt Antec with power to spare.

A 450watt Corsair, on Newegg for 69.99 will easily handle your system.
