I am going to buy ATI 4870, but I also need a new power supply for this since my old power supply is a mere 350watt. I am planning to get Corsair TX650W which has 650watt output. But I am worried about that whether this graphic card and this power supply can work well on my current desktop. I have an HP Pavilion Elite e9300z. The following is my computer info: Manufacturer's motherboard name: H-RS880-uATX HP/Compaq name: Aloe Form Factor: Micro-ATX: 9.6 in x 9.6 in Chipset: AMD 785G Front-side bus speed: 5200MT/s (5.2 GT/s) Expansion slots: One PCI Express x16 Three PCI Express x1 One PCI Express x1 minicard socket Internal Connectors: One opt fan connector One cpu fan connector Four DDR3-DIMM socketsOne 24-pin ATX power connector One front panel header Six SATA connectors One clear CMOS jumper One clear password jumper Six USB headers One IEEE-1394 front port One line-in connectorOne front audio connector One PCI-E x16 connector [J3] Three PCI-E x1 connectors One PCI-E Mini-Card connector One PCI-E Mini-Card LED headerOne SPDIF output header One PC fan connector One 4-pin ATX power connector Will ATI 4870 and Consair TX650W work well on my computer? or could any one please give me better suggestion especially on the power supply?
