Overclockers Online posted a review on the Ultra X3 800W and 1000W PSUs
Over the years, we have come to expect nothing but excellence from Ultra, they have time and time again impressed us. Earlier, we discussed what differentiates a power supply from just being another unit sitting on the shelves and what makes a power supply a good buy, it isn't always just about performance, but features, aesthetics, and price. That being said, Ultra's X3 800W and 1000W are both excellent performing units, but so are many other power supplies. But, as we have seen, there is a lot more to the X3 family then just performance.Ultra X3 800W and 1000W PSUs Review
