Be Quiet! Dark Power Pro 650W

looks like a very solid PSU

question tho i consistently find the PSU to be the noisiest thing in myu machines is the FDB system really that good is it so quiet as to be unnoticable after about 1m.

i have bought so called siilent psu's in the past only to be dissapointed

It does look very nice indeed!

It really is difficult to tell it's running sometimes. At 50% load I had to put my ear directly over it. I certainly don't use the term "silent" unless it's actually inaudible.

Other smaller players off five just to

offer?

:D Glad to read this, it's amazing how much it gets used when it's just a lie.

I like those fan connectors, they could have been sleeved though.

Rich, how quiet are these units compared with the current Corsair HX units running at low fan mode?

I guess they are fairly comparable. Or at least I hope they are!

I've not got a HX in house for comparison but Seasonic insist on using Ball Bearing fans which are quiet, but not FDB quiet.

Looks like this is the replacement for my HX620 then :)

You are going to replace a 600w+ psu for another 600w+ psu. This doesn't make any sense. Maybe you want to replace it for a 700w+ psu?

why replace the 620w Corsair Hx with thisone?

Good point.

i bought this exact PSU a month ago, and have to say its the best purchase i made. got it for £97 delivered from tekheads.

(im in the UK btw)

the only thing is the warranty, but im sure pay about £20 to get it shiped and repaired and back will be worth it, IF it does go wrong. and yes the review is right, i couldnt hear a damned thing. I thought it was broken, but then my computer turned on w.o a hitch, AND it is very stable.


for germany, they have a 48hour swap on sight service, bring there here, and it'll be amazing :)

Good review, looks like a very nice power supply, modular (yay) and a good feature set with low noise output. My only quarrel is: 4 x 12v rails... I'm lazy, give me a single 12v rail @ 54-60A and let me be :( (By that I mean another viable competitor against Corsair's and PC Power and Cooling single 12v rail line-up... the more competition, the better, and hopefully more aggressive pricing in response).

right im not sure how much load im pulling, but at 100% load with my E2140@3.0GHz :1.4 Vcore, 2.1Vram 1.6 VPLL 1.4 VFBST 1.05VSB 1.4VNB

my rails (reported by everest):
3.3V: 3.3280
5V: 5.0160
12V: 11.9840

it look's like that this psu was made by the TOPOWER for bequiet... :P

Yeah, the supply is OEMed by Topower (as are Tagan and OCZ units) so it should be fairly reliable.

I'm just doing a little upgrading and maybe have a project in mind which could use the hx. I figure if I'm ugrading bits from my existing box i might as well upgrade the psu while I'm at it but i don't need any extra power. Less noisy and more efficient is nice. Why upgrade to more power than I need just for the sake of it ? :) Or am I missing something?

No it's FSP. They used to use Topower in old revisions.

Jasio - I agree, but ONLY when a single 12V is done well with high quality components, otherwise it's a liability.

The fact that you did not test the noise level of this PS says volumes about your testing method.
Is this a joke? Would people buy a silent PS for it's power ratings or how silent it is when it's being used heavily?
I really don't take any review of a quiet products seriously unless they include some kind of db rating system, and even some audio captures at different distances.

Looks really good ;)

trust me, you cannot hear it even when you put your ear to it

What, even with its fan running max RPM? I doubt that. Does seem odd that a product named "Be Quiet!" doesn't get a noise test.

how would i get it to run at max speed?

The fan never hits that full RPM. You can't do noise tests without professional equipment and a sound room with egg cupped walls. Other than telling you a subjective level from a consistent source (my ears) having reviewed a lot of PSUs now, I have to say it's one of, if not the quietest PSU I've ever had.

I have a Straight power 550 for the past 2 years and have not had a problem with it. My only gripe is that it is not modular :)
This one could be a replacement if I ever build a new system as I have too many extra cables.
