I am building another gaming rig and currently researching the parts before I buy. I am considering a 1000 watt Crossfire ready power supply. Is this enough wattage? Below, I have listed the parts that will consume most of the power.
Video card: 1 Radeon HD 5970; maybe a 2nd one in crossfire at a latter time Processor: Intel Core i7-950, 3.06 GHz Heat Sink: Heat sink with a 120 mm fan Hard Drives: 3 hard drives in a RAID setup Mobo: ASUS P6X58D Case: The case will have 6 fans, 5 = 120 mm, 1 = 200 mm DVD reader
Please post the brand and model number of the power supply. Not all power supplies are created equal. There are quite a few low budget, low quality power supplies of questionable performance and value.
I checked several technical references. The BFG EX series is rather new. There is an overall problem with ripple exceeding atx specifications. The EX-1200 has problems delivering power at high temps. The psu is not able to cool itself adequately.
Rosewill is not known for high quality power supplies.
You can do better.
The Corsair HX1000 is a high quality power supply that would be appropriate for your system.
