Thanks. haha, im getting mixed answers. Is it possilbe to run the 7850 on my rig then? Im just slightly pissed off because when I brought the PC it stated that it was 500w. Is there any chance that this could be "overclocked" somewhat?
There are two ways of looking at it ..... will it work, and will you be supported if something goes wrong ?
The company that made the card says no. Thatz the only opinion that really counts come warranty time. The Corsair VS series is not exactly designed for being hit hard as it's a "small budget" quality unit. However it is well known that the VS450 is in fact capable of delivering 500 watts (when new). It is also known as having poor voltage regulation which could be problematic (again think warranty) and was build using very "low end" capacitors. This is a very significant issue due to what is called "capacitor aging"..... Over time, the output will drop and as you continue to pull wattage close to its rated level, things can go boom.

Any type of overclocking is outta the question....and PSU's can't be overclocked. If it was a light duty PC, I'd chance it but .... you have a faster GFX card option which if installed will meet the manufacturers stated system requirements. If you put in the 7850, Im 99% sure ya won't have a problem but....
1. Why risk warranty issues (you always could lie)
2. Why put in a slower card when the faster card requires only 450 watts
