Well last night I was having a benching session and I have a wattage meter form the wall socket to the power supply. I'm using a Corsair HX850 and the highest I seen it go was around 850 with two 7970's clocked hard. Well I'm now using two R9 290's in crossfire and I was seing wattage draw of 1050 and at I believe the highest I did see the meter read was 1058 watts. This to much for this HX 850? Also What brand on modle would you all recommend? Is a digital psu a good choice over the standard type of PSU? recommend This is what I'm looking at but are there similar ones from different manufactures of this digital design? http://www.memoryexpress.com/Products/MX40937 And will that size fit in my Corsair 650D?
