Fixed powersupply, pretty good choice since its 80+ good effiency, But im not changing GPU since this is a BUDGET pc and that is 80 dollars + 8 with shipping
Mine is 74 -free shiping, sorry its a good choice but were for the 400, dont worry i've done a mainly 500 one if you would like to see ill give you the link.
oh yes, because this is the promo By NewEGG its 15 hours now. you guys should do it quick!
Last thing about the GPU this is a GDR5 = higher tech with an excellent price.
