Looking for a silent 750W PSU recommendation for a RTX 5070 Ti build (Platinum efficiency)

Hi everyone,

I am currently planning a hardware upgrade and I need some advice on choosing the right 750W power supply.

Here is my target configuration:

  • GPU: RTX 5070 Ti (around 300W peak/transients)
  • CPU: AMD Ryzen 5 3600X (planning to upgrade soon to a more power-hungry modern CPU)
  • Case: Standard ATX case (no strict size limitations)

Energy saving is a top priority for me, so I am looking for a highly efficient unit with a minimum of 80 PLUS Platinum (or Cybenetics Platinum) certification to keep power consumption as low as possible.

My other absolute requirement is acoustics. I want a system that is as silent as possible under both idle and gaming loads.

I am currently torn between two different philosophies from be quiet!, but I am also open to other brands:

  • be quiet! Power Zone 2 750W: I love the fact that it is semi-passive (0 RPM / 0 dB at idle) and comes with a 140mm fan, making it potentially the quietest option on paper when not gaming.
  • be quiet! Pure Power 13M 750W: It technically hits Platinum efficiency in reviews with superior 28mV ripple filtering and solid caps, but the 120mm fan spins continuously.

How do these two stack up against each other in real-world noise levels? Is the continuous fan of the 13M truly inaudible, or is the 0 RPM mode of the Power Zone 2 better for a dead-silent idle setup?

If you have other top-tier Platinum suggestions like the Seasonic Focus PX-750 ATX 3.0 or Gigabyte AORUS ELITE Platinum 750W, please let me know how they compare regarding noise.

Thanks in advance for your help!

Be Quiet! Straight Power 11 650W died (end 2019 - 11.05.2026 2:33am)

It fired a 7700k with a 560Ti till 2022 and then a 1070Ti. Other components are: 4 Fans (12cm), 4x8GB DDR3 (i think) + 1 m.2 + 1 hdd over the whole time. The usage was light (mainly office, seldom more "heavy" use aka browser or opening windows media player, twice ultra heavy load aka installing windows/drivers/programs and once running benchmark for an hour to test system stability).

It died at night while PC off with a barely audible crk fzz. Overvoltage/Undervoltage/Overcurrent is out of the question, it ran in a stabilized environment. It just decided to go off while be(ing) quiet. I did not open it to check what is going on.

The warranty from be quiet for this was 5 years. The system ran stable all the time. Their promise was thus fullfilled 🫡 (aka we dont expect failure in warranty time).

To be fair: we were at least 100W away from Pmax. It ran at like 50-120W most of the time. It didn't die with a bang while running which is good. In the view of all that I'd have loved to see it going for at least 8-10 years. As comparison:I bought imo an Ultraforce 650W in 2011 which powered a 2600k then 4790k then 5950x with said 560ti, then said 1070ti, then a 2060S in a way heavier system. It got unstable, but by then it was over 14 years old (and that thing got the heavy duty treatment - like 8hrs per day+ gaming). It died end of last year.

So... My verdict: the straight line is the lower end of their lines. Price wise it was okish initial (imo 65€ in 2019), but in the view of how long it kept going rather not so good (the ultraforce was a bit higher in price at its time, but by far not 50 or 100% above). It kept the system safe even after death. So overall: it did the job well, but longevity left much open.

I'm still deciding what to do. On one hand: the system components are all quite old and efficiency is not that good anymore. I want to upgrade my girls PC. Maybe when the new AMD 10k come a 10800x3d + 9070xt - something along these lines. So I can go with another Seasonic Prime 1600 Noctua edition and just call it a day (or better 15 years) or go with a much more well dimensioned (yet more inefficient) 1000W Pure Power, but maybe have to swap it out in another 5-7 years?

Bad experience with bequiet

Just wanted to post my experience with customer support, in case anyone else has similar issues and wants to see if it has happened to someone else.

I got a PC earlier this year with a case, psu and aionl cooler from bequiet. I quickly realized that you can't fit a 5090 in the case without a huge bend in the GPU power cable, so I went on their website and saw that they sell 90 degree cables for this purpose.

In March I bought one of their 90 degree GPU cables from Amazon, which took 3 weeks to arrive (not their fault, but as far as I can tell, it is not possible to buy this product from anywhere that is shipping from inside the United States, mine came from Europe, where bequiet is based). Cable had a defect.

March 31

I spoke to bequiet customer support (after trying them for 2 days, apparently they do not answer calls during the last hour of their listed hours). I was told they would send me a replacement GPU power cable for the PSU. They said I was speaking to their branch in California, so thankfully it will be shipping from there, and will not take weeks to arrive.

April 1

I receive a follow up email asking for proof of purchase, my address to send the cable etc, which I reply to the same day

Nothing for literally 3 weeks, I am sitting there assuming it's on its way.

April 22

I receive an email saying that they will send me tracking info once the cable has been shipped. I don't know what they've been doing in the 3 weeks between getting my shipping information and this day.

May 2

I have heard nothing from bequiet since the previous email. I email them on this day asking for an update.

I still haven't heard anything since April 22. It has not shipped.

It has been almost a month and a half from when they received the required information to send me a new cable, and they have taken 3+ weeks between responses, of which we're not actually any useful information.

The thing that makes this extremely annoying is that if I had known they were going to handle things like this, I would have just ordered a new cable, since it takes nearly a month to have one shipped from a retailer.

Any suggestions on what I should do in this situation? Because contacting them has accomplished nothing so far.

I am thinking about a dark power 14 but curious if any dp14 users have any noise issues or is it being quiet?

I have been researching for a bit but there arent really any reviews most videos just talk about the specs

Edge lighting on light base 600 case

Hello everyone,

Does anyone know what type of connector the edge lights on the light base 600 case use? I want to disconnect them and connect them to another hub. If yes, could you tell me where it's located? A picture would be great. Thanks!

Bad batch of Silent Loop 3?

A friend of mine ordered a 360 mm Silent Loop 3 to my house to install on his PC while he's away.

He pointed out that there was one review on Amazon.ca (where he ordered it from) showing that theirs had leaked all over in the box, so I opened it tonight and sure enough, there is a slightly sticky and greasy fluid all over the pump block and in the bag it was wrapped in.

That review was from February and now this one in May. Is there a known issue with these and should we be concerned that a replacement might leak all over his PC at some point..?

Light base 600dx RGB

Hey everyone,

I am planning to buy the Asiahorse umbra hub soon because I really like the effects it offers. My case is the light Base 600dx, which has 2 fan hubs and an RGB strip on the right. I will connect my RGB fans to the umbra hub, but I wondered if I could somehow connect the case's RGB strip to that hub so all the RGB will sync.

Thanks for your help!

Kommt da noch was von be quiet?

Wenn ich mir das so angucke ist be quiet seit dem diese Tastaturen da sind voll eingeschlafen https://www.bequiet.com/de/press/pressreleases

Früher gab es doch jedes Jahr viele neue spannende Produkte, seit einem Jahr aber kommt gar nichts mehr außer semipassive Lüfter in Netzteilen, ein hässliches Aquarium und das Update von der Pure Loop.

Der Branche geht es bestimmt schlecht durch die Speicherkriese und so weiter aber was heute kommt wurde doch bestimmt vor 6 oder 12 Monaten angestoßen, da war doch Goldgräberstimmung. Also was ist da los, kommt da noch was außer Minimalupdates? Oder wollt ihr mit nem Launchfestival auf der Computex punkten, dann aber bitte nicht wieder nur ankündigen wie im Januar sondern auch wirklich rausbringen. Sonst kommt mein nächster PC leider bis auf mein powerzone ohne be quiet Hardware auf den Tisch.

Love the DM, to the extent that I don't mind mediocre software. But, this is too much!

I have updated IO Center to v1.1.4 today. Immediately afterwards, I checked the update via IO Center Web. That one also asked for an upgrade, not sure what version it was, though. Both updates went fine except that immediately after the second one was done, the keyboard got bricked. When I plugin USB, no power light turns on, the keys do not respond to anything and are not backlit either.

Neither IO Center nor IO Center Web detects the device.

I've tried the same on 2 different computers, via USB 3.0, different cable - no luck, bricked.

Once I plug in the keyboard, the media screen lights up for a sec, then shuts down. Numpad keys are lit ... but they don't work.

Not a single key works, nothing. 5 months old 250€ keyboard is totally bricked.

So I dm'd Stef from bequiet month ago, regarding spare coolant bottle for silent loop 3 because mine is gone somewhere. I also wrote an email to bequiet support - also month ago. As today, I did not recieve any answer.

Man I just want coolant bottle because my silent loop 3 is sometimes making weird bubble noises.

A friend helped built the PC for me so I don't know exactly how he connected fans but I have 3x140mm front fans, 1x140mm back fan and the 3 fans on the CPU AIO cooler.

The case front fan control seems to control only the front 3 fans and even though they are connected to the motherboard's Chassis Fan 1, I can't see the RPM in BIOS BUT I can control their speed (Full Speed, Silent, Standard Mode etc).

CPU AIO fans show RPM fine and I can fully control them from the PC as well as the back fan but the case's front fan controls don't affect them at all.

What is the correct way to control ALL the fans from both the motherboard (and make fan curves) and the case's front fan controller?

Thanks in advance.
