BeQuiet! Dark Power Pro 600 (+ new Straight Power line)

chompy · Post by **chompy** » Thu Sep 14, 2006 2:50 am

Hi to all,

this seems to be a really nice PSU, with lots of power and a silent performing, as you can see in reviews like this made by guru3D, but I haven't found a word about it here, is there something wrong with it that I don't know?

Thanks

Not wrong but minor details:
Like ">80" efficiency which isn't anymore highest possible, also power distribution is based somewhat to older standards/designs: 40A 5V which is ~50% higher than in most new PSUs and "just" 40A in 12V which isn't high compared to other 600W PSUs.
Like compared to 600W Straight Power model.

If you want PSU to control your case fans then that serie should be still very good PSU.

But if you don't need that feature there's PSUs with more modern power distribution, like Seasonic M12-serie and S12 Energy Plus models which are available in Europe. Basing to BeQuiet being European brand you live in Europe.
(that might be the reason why BeQuiet PSUs aren't discussed here)

For the record, the Seasonic S-12 600 W has "just" 36 A on the 12 V line. (http://www.silentpcreview.com/article247-page2.html).

480 out of 600 watts going to the 12 volt line is very good, and the extra amperage on the 5 volt line can't hurt.

Where did I mention old S12-serie?
M12 600W gives 48A, in fact 500W model gives 38A. (S12 E+ 550W gives 41A)

That again depends on how PSU is designed and how rail voltages behave when load is distributed differently compared to ratings of rails.
And drawing just 10A from 5V should be hard even for very high end PC.
All major loads use 12V, HDs draw well under 1A per drive and 1.6A was highest 5V rating in optical drives I checked.

EDIT: Almost forgot SPCR's data:
Highest consumption PC required 3.6A from 5V vs ~17A from 12V
http://www.silentpcreview.com/article265-page4.html
And for example SLI/Crossfire would consume about all required additional power from 12V.

You're right, I'm from Spain and here BeQuiet! is much easier to find than other brands (near 600W I've only found the "old" Seasonic S12 600W, Yesico SC560-AS12CF, Tagan TG580-U22, Tagan TG580-U15, Hiper HPU-4K580S and Enermax Noisetaker EG495-VE(W)SFMA V.2.0 600W).

So these are the options I have to choose...

From the (very few) mentions of BeQuiet! on SPCR, they seem to be a good brand who really do sell quiet, well-cooled PSU's. Are you sure you need 600W though?

Well I'm planning a machine for Vista with a DX10 vga and I'd like a PSU that could handle SLI, and I also want it to be silent, because I have to sleep with the computer in the same room.

I shouldn't say it - but if you want near-silence, DON'T get a Enermax...

get an Antec or a Seasonic, those are really the best, for a bit of value..

Remember that you're free to buy from other EU-countries, prices might be also enough cheaper that you'll end up "winning" even after delivery costs... sometimes price difference can be quite huge, sometimes domestic prices are even cheaper.
(from value of digicams+equipment I've bought maybe even 5% from Finland)

For example this shop has very decent delivery costs

(there's more info about ordering from them in Seasonic M12 thread)

Thanks for the link, I'll take a look and try to understand how to buy from them.

After a fast look there seems to be lots of PSU reviewed and not reviewed here, any advice on a silent & powerfull one?

Thanks

And today BeQuiet! has launched news PSUs, the Straight Power from 350 to 700W, and they look quite good in power handling, but do anybody know how much silent are they?

Well hereis one review of the Straight Power.

At least the 600W version seems to have a Protechnic fan, a medium speed version of the one in the OCZ GameXtreme wich is high speed. It's ball bearing, mga12012mb-025.

For reference, the S12 has a medium speed ADDA ball bearing fan.

If old BeQuiet! PSUs are anything to go by, the fan will run between 4V and 5V most of the time so it should be pretty quiet

Too bad that review didn't measure fan voltage, if it is 4-5V under normal use it should be about equal with the S12 in amplitude, noise character would be the important thing.

The Straight Power PSU-s are pretty much FSP Epsilons. Even the fan, cables and connectors (look at the main 20/24pin and the ATX12V connectors) are the same. (previous be-quiet PSUs were made by Topower)

So it should be stable, but probably noisier than a Seasonic S12. Seasonics can be bought in Hungary, so getting it in Spain shouldn't be very hard.

(from the review nici linked "Without any +12V railes above 18A there may be an issue with future system expansions."

well...)

Off topic... but eventhough prices are cheaper you have to remember that shipping is expensive. If the product is broken, you will have to pay from your own purse the RMA shipping costs. And the whole RMA procedure can be a pain in the arse. For the same reason I sometimes choose to pay a small premium and buy from the shops with best warranty policy instead of the cheapest place.
