I have a Dell Inspiron 545MT with a DG33M06 motherboard (Intel Core 2 Quad Q8200 2.33GHz, ATI/AMD 3450 512mb 64bit [will be changed out for the R7 250 1GB GDDR5 128bit], stock 300W power supply [will be changed for the 620W SeaSonic], 8GB of RAM DDR2) and I read on the Dell forum ( http://en.community.dell.com/support-forums/desktop/f/3514/t/19394447.aspx 5th post down) that this motherboard is only supported to 350W, is this true? I am planning to put in a 620W SeaSonic.
