Does having a better power supply boost your video cards performance and vice versa?

for example if i have a 256mb ddr3 pci-e nvidia 7600 gt and i had a power supply of 300 watts and the requirements said that it needed at least 400 watts of power would my video card perform slower? and if i got a more powerful power supply would i see a boost in performance?

Does having a better power supply boost your video cards performance and vice versa?
ur looking at it incorrectly .. having an inadequet power supply will cause unexplainable errors in ur system or can even damage components .. if u have a power supply that large enough then adding a bigger one will not help ur video .. however .. a good quality power supply will have more stable voltage and will make ur system more stable overall ..
Reply:Yes. You probably will because your video card is probably getting really stressed out with that 300watt psu.





In fact, I highly suggest you buy a higher watt psu (power supply unit) so that your video card doesnt die on you.
Reply:It is not going to work. if you have 300watt and need 400 you need 450 watt for all the other components to power.
Reply:A better power supply and an extra fan or two in the case for better cooling will help you immensely.
Reply:If you are running a power supply that is smaller than the one required for your video card your video card is probably running at less than 100% efficiency and you would take a performance hit. The rest of your system is also affected and it's not just your video card that is running sub-par. I suggest you put a bigger power supply in before you damage something. When you're playing an intense game and your machine starts to restart all by itself you will see why you should have put in the bigger PSU.
Reply:well, with better power supply mean your pc performance will be better and more stable.
Reply:Absolutely, I have a computer building guide in my forum that explains the importance of each component you select, and why.

Reply:technically it won't run slow. It will just make your system not to not be able to run stable. So if you use the 300W psu. Expect to have many crashes.
Reply:It won't boost performance, but it will help it to run smoother by giving the video card the power it needs when it needs it.





Newer PC need at least 400w. Dual videocards (SLI) need at least 650w
