Tom's Hardware Guide published a review on Corsair HX1000 PSU
A quote from the article:
It's time to look at Corsair's 1000W model. Since the HX1000 is based on a highly capable and modern CWT platform, we are pretty sure that it won't let us down.Corsair HX1000 PSU Review @ Toms Hardware
Releasing the HX PSU family was definitely a smart move on Corsair's part. It offers similar (if not higher) performance as the HXi models, thanks to extra filtering capacitors. And a lower price tag is made possible by dropping the digital monitoring (and partial control) support found on products with Corsair Link functionality.
We already reviewed the family's flagship HX1200, which impressed us enough to earn an award. So now it's time to take one step down and see if Corsair's 1000W implementation is as good. Why wouldn't it be? Well, the HX1000 does not use the same platform as the HX1200, justifying our fresh round of testing. The only let-down we've spotted in Corsair's HX family so far, though, is that the HX650 and HX750 only include a single EPS connector. Given that all Socket TR4 motherboards require two EPS connectors, we'd like to see both models with a second one.
