Q6600 and gtx 570 on 500w psu?

Hi, I recently picked up a Asus p5k mobo, gtx 570, 8gb ddr2 and a core 2 quad with some generic looking aftermarket cooler for a steal and I was wondering whether a Corsair builder CX500w I have around would be enough to power this? It is a 80+ bronze psu so it's no generic brand but I'd rather ask here first that to risk it even if it was all cheap components.

  1. The 570 requires 2 6-pin connectors. It specifies that the card uses 219W and the minimum system requires are a 550W power supply. It may still work with the 500 so long as your build is minimal(power-wise). Although to be safe, I'd probably go with at least the 550 or a 600.
  2. The GTX does indeed draw a max of 219w, but the rest of the system will prob only consume about 100-120w max. Unless your OC'ing the be-jaysus out of your CPU/GPU you should be fine.

    The CX500w is a bit vague as a description, the exact model number will be beneficial to giving a very accurate answer. Looking at a standard CX500 80 plus, the PSU could be upwards of 5 years old? It may have lost some of it's efficiency, but should suffice for your needs, as I mentioned though as long as you haven't been using it in a power system, and don't OC current components too much.

    What exact CPU do you have. A q6600 for example has a power draw of 105w. If you OC it, it could be 125w, so you just have to factor that in.
  3. At the moment it's sitting at it's stock frequency of 2.4ghz. I'm hoping to push it atleast to 3.0 but I guess that depends on what the temps allow.

    At 3ghz my q6600 was drawing 125w. That was at 1.3v vcore. What dimms are you using? If they are 400/800 then OC'ing the q6600 is just a matter of changing the fsb from 266 to 333mhz. If you have a GO stepping CPU, you shouldn't require a vcore bump. If it's the B3 version you may do.


    edit: The mobo you have is okay for 3ghz. But not much more. It's a P35 intel board, and although decent, the Nvidia 650/680 /p/k/sli were so much better. Particularly the 680. It was a hardcore enthusiast OC board back in the day. The 650 was a step down, and didn't have half the options for OC''ing, but was still good for 3/3.2ghz depending on the

    My dimms should all be 800 so I guess I'm good.
