Hello all.

I'm about to upgrade my mobo and processor from the Dell 4700 stock to a gigabyte intel board and a core 2 quad 2.4 GHz processor..and was wondeirng what wattage would be good on a PSU for that processor and a factory overclocked Nvidia 8800 GTX.

Currently running a 450W Antec SmartPower 2.0..I know that's the minimum for the video card, and it runs fine right now with the card, but I'm not sure if the quad core processor is going to suck up enough power to require to up the wattage.

Any recommendations?

More power is always better when it comes to PSUs, but the quad core shouldn't be the straw that breaks the camels back.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Keep an eye on how many amps are in each leg of the power supply as well. Most PSUs have 2 12-volt rails and sometimes the available amps can be less than you would want while the total wattage of the power supply seems to be fine.

There are a few good manufacturers to choose from and some to stay far away from. Start by reading the customer reviews. New Egg is great for that.

Good luck.

Yea i would say if your going to buy a power supply i would get one that will handle future upgrades as well. I would get at least 18A each rail on a Dual 12volt rail and 16A or more roughly on a 3-12volt rail. I would also personally look for the power supplys that are 80 plus power efficient, usually you can find them with a good mail in rebate and they wont be too much more expensive then other power supplies. Power supplies are really important so if you got to buy one spend the extra $$$ for a really good one and then you shouldnt have to upgrade it for a while.
