Is 585 enough power?

I am looking to upgrade to a 5830. I have a 585W PSU. I use a PII x3 720, 4GB DDR2 RAM, WD HDD, DVD Burner, and 5 120 MM fans. DO you think I could pull it or should I upgrade to like 650? Also it is a http://www.newegg.com/Product/Product.aspx?Item=N82E168... HEC Orion, I was wondering if I should upgrade to a big fan on top or if front and back is good for cooling?

Your PSU should be fine - even though it's really something like a ~550W PSU. That 585W rating is peak rating, not continuous rating.
You should not need any additional fans. But check your temps before any upgrades and then again after to confirm that.

That hec PSU doesnt have any PCI-e power connectors. What video card are you using now?

Follow that link. Fill in all the catagories, and you should get a pretty good idea.
Our motherboard manual will tell you a better estimate for your mobo.
Make sure you over shoot some becuase of the note on their page which is pasted below.

*NOTE:
The PSU Wattage we recommend only gives you a general idea on what to consider while selecting a power supply. PCI cards, External devices, USB and Firewire devices, Cooling fans and other components may need more power

I think going from 4850 to 5830 would be like somewhat like going from 4850 to 4890.
Not sure that's a good move. Is there a specific game you're getting the 5830 for?

Games like Sims 3, Crysis, the CoD series, Mirrors Edge, mostly the newer stuff. My 4850 isn't that great at it.

also my monitor resolution is 1920 x 1080, would the 5850 be better? I can get a HIS one for $310

This is more of a GPU thread now.

But to answer your question:
the 5850 series will run crysis at that res fairly easy.
The directx 11 capabilities are great, and it can out process a 4850 by nearly double since your going from 800 streaming cores to 1440.
Take into consideration the wattage draw that the 5850 seires will have compared to the 4850.

Is your 4850 the 512MB or 1GB model?

This 5830 review @ AnandTech shows the relative performance of 4850/5830/5850 to give you a better idea.
There is a wider margin in performance 4850-5830 in some games - others its not so major a difference.

I would do that, except I'm hoping to upgrade to DX 11

Your best bet would be to crossfire with another 4850 if your motherboard allows it. The 5830 will not give you much better frame rates over the 4850.

Then IMO save up and get at least a 5850. You should also upgrade your PSU when you do this I would not trust that hec PSU with a high end GPU if it does fail it could possibly take some other components with it.

Ok, so I guess a 650W like Seasonic, OCZ, or Corsair would be good.

Yes all good brands just be careful of some OCZ PSU's some are better then others.
