Right, I do not need anything professional and expensive, I need it for home video editing and home pictures processing only, and I don't expect super fast performance.
Please explain me how can I make sure my computer has A Quality PSU with PCIE 6 pin power connector? More over, I'm not even sure if it fits my single slot inside my desktop, it is a HP Pavilion Slimline s5257c, so it's slim box design, much slimmer than regular desktop, like this: http://computershopper.com/desktops/reviews/hp-pavilion-slimline-s5160f
. Is any way to check the compatibility? Should I contact HP support?
