Straight Power 11 is certified with 80 PLUS Gold efficiency, reaching up to 93%. This offers lower energy consumption and cooler and quieter operation. Truly an advantage for any system.
Thanks to the modular cables, all cables that serve no purpose in the system are omitted. For this reason, systems always appear very neat. At the same time, installation is much easier. A smoother airflow results from the flawless arrangement of the system, which means that lower noise levels and temperatures prevail inside the case.
The high-spec Silent Wings 3 fan provides the best possible airflow in its class while producing minimal noise. This is due to the unique, optimized design of the fan blades combined with an advanced fluid dynamic bearing and a 6-pole fan motor that largely eliminates operational noise, has an exceptionally long lifespan, and minimal energy consumption.
Experience the most technologically advanced power supply ever built by be quiet! Utilizing advanced full bridge, LLC, and Synchronous Rectifier (SR) technology, it provides unparalleled signal stability and unmatched power efficiency. The DC-to-DC conversion for strict voltage regulation, even under heavy cross-loading conditions, ensures reliable operation for the next generation of processors and graphics cards.
Only the best components are used in the Straight Power 11 Platinum. That is why we have incorporated only high-quality Japanese capacitors into the power supply unit's framework. They are rated at 105°C, ensuring stability, reliability, and long lifespan.
An absolute innovation: The Straight Power 11 Platinum has no cables on the DC side inside the power supply unit. This results in improved cooling airflow and fewer signal disturbances, simply due to the lack of wiring, ultimately pushing the lifespan of the components to the maximum.
The Straight Power 11 protects your PC from over power (OPP), over voltage (OVP), under voltage (UVP), over current (OCP), over temperature (OTP) and short circuit (SCP).

Excellent power supply. Completely silent (the fans of the AIO are louder) and very stable voltages even under overclocking conditions. The cables are of high quality, with good sleeving and capacitors on the SATA cables, therefore they are quite rigid which poses a problem for cable management. In conclusion, I prefer good performance and stable voltages over beautiful cable management at the back of the case that I don't see anyway, so I easily give it 5 stars.
A purchase was made for a high-end build, and I will share some things to help you make an informed decision.
+ The power supply's operation is (almost) silent, you will have difficulty hearing any noise. Even if you push it, the noise is masked by the other fans.
+ (Platinum) High-quality materials used. Gives a sense of durable and reliable construction.
+ I had no issues with voltage fluctuations during idle and cinebench/benchmark.
- Cable management may be difficult for some, as the cables twist with a little difficulty, so it may not be suitable for small cases if you want organized cables.
- The price may deter someone on a budget. I believe the price difference with the gold plus will be offset in the long run. I personally find it to be quiet and delivers what it promises, 5 stars.
Excellent construction and quiet.
The cables are well insulated but a little difficult to twist with ease.
It's worth it!
Quality and silent to the point that sometimes when I turn on the PC, it takes me a moment to make sure that I actually pressed the button if I'm not looking at the screen.
It can handle a 3070 and i9 13900k without any issues.
Very low noise, I was impressed by how flexible all the cables are and it makes cable management very easy. A plethora of cables for any use, sturdy construction, you can tell right away that it is made from quality materials.
The computer opens and you don't realize it until the lights turn on... The most silent power supply I have ever seen
Very nice and high-quality power supply. I haven't heard it even once. It has a lot of connections (especially PCIe, it has 6 in the 1000w model). The only negative is that it is very difficult to do good cable management because the cables are stiff, but other than that, I would recommend it to everyone.
After 7 months of use, the 850w made a bang and smoke started coming out. On the bright side, it didn't burn anything else along with it.
By chance, I switched to this power supply due to a new graphics card, and I couldn't believe my ears! For so long, there was a constant computer noise, and I thought it was normal! But it turns out that this noise was coming from a €60 PSU that I had installed! I couldn't believe my ears!!!
Well, the power supply I got is the 750W Platinum Full Modular. It's excellent and I have nothing more to say than what others have already said. It's worth the 125€ I paid for it, just be careful with the number of connections because for some reason the company released the Platinum version with fewer ports than the Gold. It won't affect you in anything, even if you have 10 cores or more processor, since the extra P4 needed for these processors for power supply is unnecessary, unless you're doing crazy overclocking with liquid nitrogen.
I will update my review in depth over time.
It's on a mining rig and works tirelessly and quietly 24/7, 365 days a year... all other uses you can give it are inferior to what it pulls with me
I had a problem with the 3060ti, which was flashing the 2 red lights above its power supply, indicating unstable or unsatisfactory power supply to the graphics card from the power supply, according to the data of the new Ampere architecture used by Nvidia in its cards. The results were immediate with the installation of the power supply. The card immediately calmed down and I was able to raise the clock and frequency even more. Heavy and high-quality construction, it immediately shows that this power supply is a premium+ construction. Japanese capacitors everywhere, everywhere protection (OV, OP, OC, LC, etc.), this power supply is a decade-long investment. If someone has the budget and wants to buy a power supply of this class, they should choose this one without a second thought. 9.5/10 with 0.5 deducted due to the high price. Flawless. The evaluation refers to the 1200W version.
Excellent power supply, I bought it about a month ago because my previous one failed. It is a well-crafted design, the cables are of very good quality, and their labeling is clear. It is large in size, so be careful about what case you will put it in, but I managed to fit it in an old masterbox lite that is relatively small and had a bit of trouble, but overall I had no issues.
As soon as you hold it in your hands, you realize that it is a premium construction! It is completely silent and comes with a plethora of high-quality cables! You really enjoy assembling the cables (only the ones you need, as it is fully modular)! It is truly an exceptional and high-quality power supply!
Good appearance and quality construction. The cables are a little different from the previous ones I had, but easy cable management and I managed to adapt them to my needs (4 sata power, 2 molex, 1 pci, 24pin, 8pin cpu). Easy connection from both sides of the connections. Satisfactory cable length, good cable braiding.
An exceptional power supply...be quiet...once again shows its teeth in terms of build quality...I paired it with the be quiet pure base 500 case...I left the case open on one side on my desk and thought my computer was turned off...also, the full modularity for cables is amazing....a blind choice for anyone who wants a reliable power supply....mine is 650W...
Although it's only been a few days, I can say that it's quiet and high-quality. The connections of the modular cables are made with clips on the power supply, so I feel confident that nothing will come loose if they're moved when I clean the PC.
The warranty is 5 years, so there's no need to worry about anything in this area... If something goes wrong after 5 years, I won't even cry...
I plan to push it with a strong OC, so if it disappoints me, I'll come back. If I don't come back, it means it's a winner.
Unbelievable power supply for the money. I chose the platinum mainly because it was roughly the same price as the gold and I knew it would come in handy. Currently running an i5 10600K with a 1060 3GB, but most likely will upgrade to a 3060ti and I'm sure it will work perfectly until then. 100% recommended.
I have a flawless system with an Aorus X399 motherboard, Aorus 240 liquid cooler, and an Aorus 3060 Ti graphics card. It has all the features I want and is generally sturdy and quiet in all my applications - simply amazing
It is the first PC I have ever built, so I don't know how good or objective of a review I can make, but I will try.
11/2/21
It was purchased for 100 euros, it has 1 cable for the motherboard 5V,12V, 1 cable for the processor, 3 cables for SSD where they can support up to 10 SSDs and 2 HDDs (if I remember correctly) and 2 cables for graphics. I had no complaints, everything is good and it seems to be of good quality.
It's better to watch this video that explains it correctly hahahaha

Be Quiet Straight Power 11 650W Full Modular 80 Plus Platinum
Simply the best I have ever worked with, and the CPU's extra features are top-notch for a PC with an x399 Aorus setup that requires both 8-pin and 4-pin connectors. It performs exceptionally well and is completely silent
Good power supply but I don't like the way the cables are arranged. For example, you want to plug in the 8-pin CPU power into the motherboard and instead of 1 8-pin cable, it has a cable that splits into 1 8-pin and 2 4-pin for extra power. You don't need to connect those to any motherboard and you just have an extra cable taking up space.
The same goes for the PCI-E, which has 2 12-pin cables that split into 2 6+2 pin. There's no issue with the rails, it just takes up space even though most mid-high range graphics cards require at least 8+6 pin for power, so you're covered.
I want to add that it has very long and thick cables, which means you have to gather them all at the bottom of the case. I highly recommend that if your budget allows it, you measure how much cable you need and add 10-15mm extra and get custom cables, at least for the 24-pin and 8-pin. Especially the 8-pin CPU is the worst in terms of space since no CPU requires the extra 4-pin for more power, even on the new Ryzen 9 5950X.
I got it because after installing silent fans in the case and processor, the previous power supply (a Coolemaster g750m) was very loud and drove me crazy... As soon as I put it in.. "dead silence".. the whole room quieted down and now in Idle Mode nothing can be heard.
At first, I was a little scared before making the purchase because there was no review on this power supply, but I think I made a good start. It has everything the user needs and keeps the voltage stable, which is very important as the power supply is the heart of a system. It doesn't make any noise and has all braided cables without any plastic or ugly multicolored ones that exist in others. It is a new product that competes equally with the top-rated power supplies in its category. For me, it was a risk. Although be quiet has been in the industry for years, it is still new, and I didn't know if this implementation would be good. However, the purchase was one of the best I could make.
