At that price it's an excellent deal - I would probably get one as well... I wouldn't expect to get 600w out of it at all since they are usually rated at max so 500w or so would be a much more realistic expectation. Seriously 600w for under $100? :roll:

of the older V-series units, when the power draw approached the rated wattage it becomes out of spec, and that's asking for trouble. So just don't run SLI mode will be fine :wink: they are not bad for a budget PSU.
