Upgraded my processor, do I need more power?

I've ordered a Core 2 Quad Q6600 to replace a Core 2 Duo E6750, and am aware that the new processor will use a little more juice. Do I still have enough?

My system is:
500W PSU
Core 2 Quad Q6600
GeForce 8800 GT
2x2GB RAM DDR2 800Mhz
2xOptical Drives

It's been running fine for a long time with the old processor.

  1. What make and model of PSU do you have?
  2. Chances are you won't need a new power supply given its a decent power supply.
  3. I didn't want to say - lol - I've read a lot of forum threads dissing it. It's an Arctic 500W, but I'd been delighted with a bunch of Arctic fans I bought once, so I trusted the company with my PSU.

    My concerns come from this http://www.tomshardware.com/reviews/geforce-8800-gts-512-mb,1743-13.html which suggests my graphics card could draw as much as 227+watts, but wikipedia says a 8800 GT has a 105W TDP. Shortly after reading all this, my brain went wibble and I needed to ask for help.

    Edit: I found this, http://www.pcpower.com/technology/power_usage/ and after a quick totting up (using the high end for most parts), I soon racked up a large number of W's.
  4. I believe the 8800 GT only uses 105 watts when maxed out or stressed to 100%. That tom's page might be the entire system (which is likely). Also that link you have shown says one pci-e connector can use around 50-150 watts, the 8800 gt has 1 pci-e connector so it is within 50-150 watts. Only the high end video cards consume 200+ watts or the older video cards back in the days that were high end.
  5. Thank you socialfox, you are correct it is the whole system, I didn't spot it before. This has definitely put my mind at ease.
