JonnyGuru Review of the Koolance WC 1200w PSU

Knowing that this is an "overclocked 850W", the first thing that impresses is that it can in fact do 1200W. Bravo Koolance! Liquid cooling does work. Not only does it put out 1200W, but the voltage regulation is very good all of the way up to 1200W!

I HATED giving this thing a low score. And I would never tell anyone that this power supply is NOT recommended, despite the fact that it only scored a 7 and didn't get a "Recommended" award. But the fact of the matter is, it's an 850W power supply being sold as a 1200W power supply at a cost of around $500. I bagged on the efficiency, but it really wasn't too bad. I bagged on the ripple and noise, but at loads under 850W (where 99% of you guys and gals will be 99% of the time) it was within spec. The coolness factor and just the aesthetics were off the charts though. In fact, even if this PSU wasn't water cooled and instead was an air cooled PSU in a laser etched aluminum housing with stainless steel panels on the top and bottom, it STILL would have scored a 10 in the aesthetics category.

Plain and simple, the choice is up to you. That's why it's so important to not just read the beginning and end of a review and actually read what's in between. Because even though this power supply didn't score a 10, I still like it. Has this happened before? Yes. The SevenTeam ST500EAZ I reviewed last year wasn't perfect, but I liked it. So I used it in my own machine for over a year. Not every good PSU is going to score "perfect." Not every "perfect" PSU is perfect for everyone. This is a good power supply. It's expensive, but if you want people to stop and leave a puddle in front of your PC as they walk by at the LAN parties, then I strongly suggest giving the Koolance consideration.
Once again...
