Hardware Be Quiet! Dark Power Pro 850W

http://www.bit-tech.net/hardware/psus/2009/04/09/be-quiet-dark-power-pro-850w-review/1

We constantly recommend the 650W Be Quiet! Dark Power Pro, but does the 850W afford the same awesome efficiency and virtual silence? With the same style of modular cables, shiny box, and a very similar build it be just as good or it might suffer from being just too hot.

 

I really want to be able to afford a new PSU and this looks ace. Can't though. Even the 650W would do fine. Need to stop buying all these damned Steam weekend deals!

 

Bought the 550 watt version from Scan. Very happy with it it's a lot quieter than the 480 Hiper Type R I was using.

 

Thanks wanted this review for ages, much appreciated....

 

I kinda feel like this PSU should be given a "Bit-Tech Recommended" -- maybe not the Gold one, but the regular one. Even Corsair doesn't offer a modular PSU in this range, the HX620 and then HX1000 leave a giant void, particularly since 620 watts is perfectly fine for a premium system, but the HX1000 is overkill under most circumstances. The 750-850 range is sadly devoid of quality modular PSU's. And heck, it's good to see new manufacturers creating interesting products.

 

I got one of these a couple of months back, very very good, quiet but still the loudest part of my water cooled system, well worth the money.
I'd reccomend these to anyone.

 

Yes it is very, very good - maybe I'm a bit harsh - it does hit 9s and high 8s, but I felt the quality like the M12D and Antec Sig are that much more, or, the Corsair is that much cheaper too. It's a great middle ground modular product, but maybe it's also slightly too hot too and not suitable for everyone.

We're notoriously hard markers because you lot demand us to be - and like I said if you bought one you'd certainly be pleased with it, it's just not a universal recommendation like the Cooler Master UCP 900W.

 

Love these power supplies. I've got the 500w Straight Power and it's never let me down.

 

Got the 750W one on a core i7 920 OC'd+gtx 280. Very happy with it.
Great product, their customer service is the best I know. (free number, knowledgeable people in my country, very friendly)

It's a bit expensive (still, less than some others) but REALLY worth it.

 

I rather see BT test systems on their true power needs. Does a low/mid/high end PC really need a 800w PSU. And what PSU is more efficient in such a system.

for example a pc with a intel 775 motherboard and quad core, 4 hd's and 1 Recent Graphicscard. Or one with SLI/crossfire. Amd system with same configs. Or a highend (modded) over the top system filled with watercooling, 4 disk array, triple SLI/Crossfire, blinky lights, fan controller, lcd display and such. Does it need a 1200W PSU or can it do with a 550W PSU...

 

Power consumption is in every other review: notably graphics.

You simply can't test every different iteration.

 

Looks very nice, but not enough to convince me to upgrade from my Corsair unit.
