Load regulation is not tight at 12V. It is the other way around on the minor rails, but the 12V rail is the most important. I expected more from the digitally controlled 12V regulation circuit.

Ripple suppression is good but far from what the aged Corsair AX1600i unit’s platform offers.

As always Aries, very nice review and thank God it is a decent PSU given its price (even in Euros).
It’s a very quality PSU, from packing to accessories, and it works well.
I bought it a few days before you released this review, believing it would be good enough considering its low (for a 1600W PSU) street price, and your post was such a relief.
Alternatively, the GF3 1650W is really affordable for those who won’t push the PSU to its limits (working around 40-60% load) and can withstand the increased noise output. You can’t have it all in most situations, it a fact in all aspects in life.
Of course, with this lower cost, some things aren’t perfect compared to the completion, but it’s a very affordable and performant PSU.
Thank you once again for the detailed and quality review, and may God bless you all in your new endeavors in the biggest Greek island (Cyprus, of course!) and fully self-employed situation, Cyprus helps a lot new businesses to flourish compared to mainland Greece.
May the Lord bless all over there!
Thank you Xaris for your kind words!!!
Users should be aware that my dark power (non pro) 13 1000w exhausted an oil/chemical like smell for over a week. Eventually did burn off. Also made me sick half a week later. Or could of been something else. Interesting timing though. Mo other issues than that. Has been rock solid for my gpu can cpu and system in general.
Their execs should change the company name to “be loud!”. Company employee which market quiet as their slogan, should deliver quiet even at > 1000 watts.
31 dBa is very audible (like a conversation), and for me with my bat-ears, loud and annoying (commented on the Cooler Master V750i Gold PSU review).
I got myself the fsp hydro ti pro 1000 watts you tested here, and I can hear the “dead low” 13 dBa from 2.5 meters away at evenings or night, but not the fan, only the shoveled air circulating; the psu delivering maybe 100 watts.
Though (obviously) I must say this is very silent, like a very quiet whisper, no problem at all, and the noise is drowned out the moment any cpu- or graphics card fan kicks even at 600 rpm.
It’s less than half as loud as my previous seasonic tx 650 watts. The psu is even smaller than the seasonic; very laudable achievement!
So whoever has bat-ears as myself, and wants a super silent or inaudible build, I recommend the fsp hydro ti pro.
Just received the 1300w version.
I have no idea what connectors are inside. I shall email them and ask them I guess.
I will reply add a comment when I get confirmation.
After contact through messaging the BeQuiet people told me there is no change of the connector on the PSU side and that the change is only on the GPU side.
I would not feel fair by saying that they just try to hide that their newer serials do have the new conenctor. I could bluff and tell them that a friend of a friend got one with the new connector but apart from Aris’ mention of it I have not seen it anywhere else.
After spending 1000s of hard earned euros on BeQuiet products, I feel a bit cheated on how they address themselves regarding this, since it could potentially be a hazard as well, knowing nothing about future compatibility with newer hardware in the future. They insisted that we cannot and should not speculate as customers and just buy whatever is available now. Which I found rather rude to be fair. A 450eu PSU is not something that belongs to your open market shopping list, but something you research about and hope to have for at least 8 years. So speculation plays a huge part in such a purchase.
Seriously thinking about returning it and getting either the PX or TX 1300 atx3.0 Seasonic one.
I just received an Be quiet! 12v-2×6 90 degree cable, I tested it with multimeter, the pinouts are NOT pin to pin like other 12vhpwr cables.
So does Be quiet! have their own 12vhpwr pinouts?
they could yes, but it sounds weird.
I also bought the angled 12V-2×6 – 12V-2×6 cable from be quiet! and tested the pinout on the included 12VHPWR – 12VHPWR cable, and the paths do seem really weird.
But if it works I guess there’s not really anything for me to worry about?
be quiet! is a big and respectful brand. It wouldn’t offer something that could harm its good reputation.
Hi, very good article! Thank you very much, it must have taken you a lot of work to do it xD.
Would you consider the be quiet! BN517 Straight Power 12-1200w as a good purchase option?
