The one I received was DOA however after sending an email, sending the product off and waiting around 5 days I got a new one. I've had a working one for about 3 months (got it end of august) and its fine ever since. The watt power is at the perfect spot as it leaves room for some upgrading and provides enough power for pretty much all parts available right now. I use this with a GTX 770 and haven't had a problem (apart from the DOA). Recommend this to anyone.
