I want to replace the current power supply (220w) in my Gateway SX800-01 desktop (Model: SX) computer. I am not familiar with the type of power supply it contains. It seems small, slim, and long (height~1.5") and I have found power supplies that look similar to it called by the forms Flex ATX and 1U. Would someone clarify that for me, please?
Also, where could I get a power supply with a higher watt capacity (around 400W) at that form to where it would fit my computer. I believe that I need a power supply with a 6-pin PCIe connector since I am looking for a higher watt capacity power supply for an NVIDIA or ATI video card. Many of the PSU I looked at don't have that connector, will I need one and if so, do most of these PSUs I'm looking for have this connector?
Thank you.
