Looks like that should be plenty large for your system. I find that particular PSU calculator to be very helpful as it provides so many details
bigger psu = better for future upgrades. You might want to look into the 6600 also as it is only about $70-80 more and has twice as much l2 cache. But if your on a budget then stick with the 6400
actually i spoke with one of my sellers who is testing out builds for a Conroe system and he told me specifially that the NeoH PSU have compatibility problems with the new conroe system. soo im going to a;
PSU: 550W E-Power Tiger EP-550P5-T1 ATX12V v2 and EPS12V 24pin/20pin Power Supply SATA PCIe SLI Ready $82.80
i want the 6600 buts its a $105 price jump
If your gonna pay 82 bucks for a PSU, might as well pay a bit more and get an Antec TruePower. Probably the best 550W PSU for that price range. Everything else looks good to me. E6600 is recommended, but like others said, if your on a budget, then 6400 should be fine.
i decided on the e-power because it was recommended by my seller and he said he tested it with the conroe system and it works great.
430w isnt enough for what i have listed?
I suggested the upgrade in power simply because if you plan on upgrading in the future there is a pretty good chance that you will need the extra power.
