Graphics Card Power Consumption

[knightwalk]

My System Specs:

CPU: Pentium 4 1.7Ghz
MOBO: A-not-so-branded MOBO
RAM: 640 SDRAM
HD: 2 hard disks
GPU: Nvidia GeForceFX 5900XT
CDROM: 1 CDROM drive and 1 CDRW Drive
PSU: A-not-so-branded 400W PSU
SOUND: Soundblaster Live 5.1
FLOPPY: 1 drive

My question: Does my graphics card require more power consumption in order to function well? I understand that my processer and rams might be the main bottleneck for the performance on the GPU, but if I upgrade my power supply to those branded ones, will it be able to give the graphics processor more juice and will it increase its performance?

If the graphics card is running fine right now at some graphic intensive games, there is no need to upgrade the power supply. Upgrading will not give any performance boosts whatsoever.

uprgading your psu would not make your video card peform better. If you system was unstable, and crashing in games, then you may want to consider the PSU. Your cpu, and Ram are definatly the bottleneck, sdram does not feed a pentium 4 nearly enough bandwidth, and the 1.7 is a williamette core, which was a very handicapped cpu.
