hi, so thanks to a few other threads, i have decided i will upgrade to a fx-8320 and a 7850 2gb. nw what i need to know is will my 500w psu be enough? its an ocz corexstream 500w. i dont plan on overclocking until later in the year when i do get a new psu. if i dont need one, i can get a new keyboard/mouse. so do i need one?

More about : 500w

"500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7
600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology."

so yes

For a system using a single AMD reference design Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector. Some of the non-reference design Radeon HD 7850 graphics cards require at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The OCZ CoreXStream 500W (OCZ-CXS500W-??), with its maximum combined +12 Volt continuous current rating of 37 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7850 graphics card.
