Hello, maybe some one could look into my build and tell if the " Enermax PRO82+ 425W " is good enough for it? Extreme power supply calculator reports 388W recommended wattage for the psu, so i just want to get a side opinion
GPU: Asus Radeon HD 6670 1GB GDDR5
CPU: AMD Phenom || x4 965 Black edition
RAM: Two sticks of "DDR3 Crucial Ballistix Sport 4GB"
Mobo: GIGABYTE GA-78LMT-USB3
SATA: 1hdd 3'5" 7200rpm
For a system using a single Radeon HD 6670 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 20 Amps or greater.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.
You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers overstate the power supply wattage, usually by at least 50 Watts, in an attempt to take into account some of those power supplies that have the weaker +12 Volt rail(s).
The Enermax PRO82+ 425W (EPR425AWT), with its combined +12 Volt continuous current rating of 33 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 6670.
