Solved unsure about a graphic card installation

Specs: Windows XP
Can I install a graphics card that requires a 300 watts of power to run on a 250 watt rated computer? What if any adverse effects would it have on the system?

✔ Best Answer
Peak power is only drawn if the card requires it, so if you are running graphically intensive games you may not notice a difference immediately, but as soon as the system is put under pressure you will find that it just freezes, or shuts down, it may even damage the system if the power supply is a poor quality one. You definitely need to replace the supply with one capable of handling the total possible requirements of the system, it is false economy to buy a powerful, expensive card and expect an under-powered supply to do its job.

Thanks, John R
You have confirmed my suspicions about it. I will be looking to upgrading my power source.

I think you're confused about the wattage recommendation. Very few cards require 300W & the ones that do are on the extreme high end. When a graphics manufacturer recommends a minimum PSU wattage, it's for the enter system with the video card installed, not for the video card alone. The manufacturers realize that not all PSUs are created equal so they play it safe & over-recommend the wattage.

Please post your complete system specs, including the power supply specs (not just wattage), & the make/model of the video card you plan on getting.

In the meantime, here's a chart that should give you an idea of the power required for just the video card:

If your card isn't on the list, just do a google search using the make/model of your card along with the terms "power consumption" or "power requirements".
