Hey. Just got a Antec EarthWatts Green EA-430D Green 430W Continuous power ATX12V v2.3 / EPS 12V 80 PLUS BRONZE Certified Active PFC Power Supply on a good deal. Was wondering if it would handle a 6850. My processor is intel i3 2100 and my hard drive is 500g seagate barracuda. If not would it run a 6770 fine? Thanks

You'll be ok as long as you're not going to CFX (for the 6770).

Actually if I were you I'd go with this one:

You should know that with the one you got a "good deal" on you are even a little below the recommended minimum of 450w for the 6770 (600w for cfx). The 6850 is a recommended 500w. The one I recommended above will handle most SLI/CFX setups and has plenty of amps on each rail.

Will handle it without a problem.

You should have no problems. That card consumes about 130W by itself at max load, and the CPU is rated 65W TDP but really consumes much less than that. Hard drives are not much to consider unless you have a lot of them; maybe 10W apiece when active. So you should have plenty of room.

Manufacturers always WAY overstate the power requirements to cover their own asses, because they have no idea what your build is, and for all they know you're an idiot who also has a space heater and two refrigerators hooked up to your system somehow.

Also, there's a pretty handy tool for overall system power consumption here:

Your setup ran through at 241W after allowing for a few fans, two sticks of RAM, and a DVD drive in addition to what you listed. So pretty much in line with the results in the post above.

For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The Antec EarthWatts Green Series 430W (EA-430D Green), with its combined +12 Volt continuous current rating of 32 Amps and with one 6-pin PCI Express supplementary power connectors, is sufficient to power your system configuration with a single Radeon HD 6850.
