The rating

be quiet!'s newest range of premium power supplies are the Dark Power Pro 10. Spanning from 550W to 1,200W and certified to either 80 PLUS Gold or Platinum efficiency levels, the 850W Platinum model, as reviewed here, represents cutting-edge technology in a market that can be slow to innovate.

Using Seasonic's Platinum 860W as a base and improving upon it with a tweak of the internal architecture along with a revised chassis and rail-switching key, performance is very strong in all areas. Bountiful cabling and whisper-quiet operation, albeit not silent, add to the list of features. We have no qualms about the quality of the Dark Power Pro 10 850W PSU but are concerned that the manifest performance and design benefits arrive at a retail price of £165 that is hard to stomach.

Be quiet! will rightly claim that a Platinum-rated supply of this capacity isn't going to cheap - the Dark Power Pro is actually one of the cheapest of its ilk - so if you're after a very high-quality PSU that should last longer than the manufacturer's five-year warranty, it's a good bet for a genuinely high-end build.

The Good

Great aesthetics
Very solid performance
Cables ahoy
Super-quiet in use

The Bad

Price, but Platinum-rated supplies are inherently more expensive

If only I could afford something like this in my new rig. Nice to see that everything is moving towards quieter and more efficient supplies rather than fire breathing monsters at 15 million watts where you have to use headphones to use.

Nearly £30 premium over the Corsair AX850 which is already at a premium. I think the cost of this is just too much - regardless of how good it is.

if it's as quiet as they say .. then could be on a winner .. my corsair is the noisiest thing in my system and full power is very anoying

I bought the AX750 expecting a long life out of it for that premium but the series is a couple years old now and gold certified rather than platinum, so I'd expect the Be Quiet to be a little pricier. I'd probably not pay more than I did for my AX750 though, without SLI it's more than enough for my system.
