2.I though if you over load the PSU it will simply burn up? 3.Sense when does the PSU effect the performance of the video card? What does the video card not work as well if it sees a slightly lower voltage level due to an extended load on the PSU or something?
1. For minimum requirements you should always refer to the Video cards minimum requirements section, usally stated on the box, manual or even the website its sold on. Don't ever believe what dell tech support says and lastly thats only the requirement for the card, it does not factor in what you ALREADY have in your PC. Therefore you should always have 100 or so More watts on a power supply then you need. That doesn't even consider future upgrades en such.
2. POS power supplies will Burn out/Exploud and die when overloaded or overheated however, Most newer power supplies simply switch off If overheated or Overloaded. But you should NEVER have to overload a power supply. You should always have more wattage and amperage then the minimum.
3. The Quality of a power supply affects preformence of your video card and every other component within your system. If you have a POS PSU or its under heavy Load, your computer will not preform to its max and it can cause random freezing, lagh spikes and other undesierable affects. This being said and to reiterate everything else stated, a Power supply is a very important part of your computer you NEVER want to get JUST the minimum nor do you want to go cheap on a power supply.
And if you do you should NOT be dissapointed when it does not preform well or Dies and takes other components with it.
Edit: If you have a Dell or any other propritary Computer you USALLY need to buy a Upgraded power supply from the manufacture.
