HD 7850 w/ Cougar ST500

[SystemDown]

Will my power supply provide enough power for a Power Color HD 7850 2gb????

The ST500 should be able to power the HD7850 (due to the 500w rating) however I wouldn't trust a Cougar ST series inside my machine. They're made by HEC; they get mixed reviews all the time.

Regardless, it should be fine.

My other power supply option is a Fsp Hexa he500

For a system using a single reference design Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater 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!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated @ 45°C - 50°C ambient temperature, is the most important factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the 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 you are trying to achieve.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers may overstate the power supply wattage, usually by at least 50 Watts, in an attempt to take into account some of those power supplies that have the weaker +12 Volt rail(s).

The COUGAR ST Series 500W (ST 500), 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.

The review of the COUGAR ST Series 500W (ST 500), that I've read, shows that it can deliver the power stated on the label while maintaining low electrical noise and ripple.
