Hello, I am thinking of upgrading my graphics card to the GeForce GTX 670. However, I don't know if my PC can handle this. I don't know what specs you need to know, so just ask and I'll find out, Thanks
The minimum system power requirement for a GTX 670 is a PSU with at least 500W with two 6-pin supplementary power connectors. If your actual power supply is less than 500W, then you have to get a brand new one.
Your power supply is the thing on the top left where all the cables are coming from.
You can find all we need to know about you powersupply on its side.There should be a power destribution table like the one on this power supply.
If your power supply has more than 30A combined power of all 12V rails.Or it may be just one rail like on most power supplies.Than its good enough for a GTX 670.If on the other hand it has less than that... well you better buy a new one.
