619 is well and good but it doesnt say how much is cross loaded what the demands on other rails are so keep that in mind. 8350 oced can hit 200+w and 7950s overclocked can hit 250w 250+250+200 = 650 add in fans hdds pump motherboard requirements etc.
take it from someone that has overloaded and blown up a part or two lol. Chief Broken Rig is a title i have earned  |
Well the web site that estimates the power needs asks whether you have a high end motherboard, which obviously uses more power, they ask about all attached devices, amount of memory, how many hard drives, how many ssds, what kind and number of front bay peripherals, like card readers, extra usb hub, etc. It is ALL factored in. They know what they are doing and they mention power requirements for all the rails is factored into their formulation. They even ask to what GHZ you plan to overclock the cpu. They ask cpu model. I have complete confidence they are on the money.
