Yeah, there are a bunch of 670 threads already, but they didn't help me much.
What are good PSUs around $100-$150 that will support it's Amp requirements? I'm lost on how to read the amount of Amps PSUs give.
Nvidia reccomends 450 watts / 24 amps and dual pcie connectors Oops, that's for 660Ti, sorry, it doesn't change my last statement
Single rail are easy to read, what's it say under the 12v output ?
Multi-rail is a little different
This label is just an example, and is an exception to the rule that rails are not additive
2 x 17a, below the chart we see that the 12v rails are capable of providing 408w
And a different way of showing it, follows the rule of the rails not being additive
2 x 20a that combine for 384 watts
Understand how to read the amount of Amps now ?
Won't make reccomendations without knowing the rest of your specs but there are several 450 watt units out there that are of high enough quality to run most basic single card systems and will cost you $100 or less
All points out to 750W being more than enough for x2 670 in sli .Keep in mind It's not the power supply's wattage that determines whether the graphics card and system will receive sufficient power. The only power supply specification that really matters is the combined +12 Volt continuous current rating. If you don't meet this specification requirement your system isn't going to work properly no matter how high of a Wattage the power supply claims to have.
