Yes. They also have no idea if you are running a quality power supply like a SeaSonic, or some POS generic McPowerSuperMax that may be rated for 950 watts, but will explode if you draw more than 420.
As I stated in a prior message, the 5770 itself is rated for a maximum board power of 108 watts. Two of those and a 2500K (not overclocked) have a nominal maximum load power draw of 311 watts. Overclock each of them, and you're still going to be under 450 watts. > -----Original Message----- > From: [email protected] [mailto:hardware- > [email protected]] On Behalf Of Anthony Q.
