Power Supply

[tomacer17]

Hello,
I do currency trading with Four 19 inch widescreens,and usually 3 windows minimum open at a time.
I have a AMD Athlon II X4 640 cpu, one pci espress video card, and one pci video card. My older system with a Athlon X2 I ran a 750watt PC Power silencer. What should I use with the Amd 640 ?

The same if you still have it. Otherwise, look for 750w in corsair or antec.

It will depend on the video cards. If they aren't gamer cards, for example need no auxiliary power, a 380W Antec Earthwatts would run your system without breaking a sweat, as would a 430W Corsair "Builder" series. If they do need auxiliary power, let us know what they are; you're still not likely to need more than 500W-550W.
Of course, if you still have the 750W PSU, you could always save $40 or so by re-using that.

PCI cards are very low power so as long as it doesnt have two molex connectors plugged into it or another auxiliary power source and the PCI-E card isnt taking more than one 6 pin connector something like the EA380, EA430 or 430CX would be plenty.

Nothing except two high-end graphics cards at once will take more than 750.

Yep, anything from Corsair, Antec or Seasonic.

Lots of low end ps for sale used on anandtech. Otherwise, get the 750 on sale when you find it for less than $100, so you won't have to upgrade the ps again.
