Very good power supply, the current is stable but it has only one disadvantage. The power supply produces a lot of heat and does not help much my processor which does not have good airflow in my case.
This is my first be quiet! power supply (700W version). I have installed it in my mid-range PC (MSI MAG B560 Tomahawk, Intel Core i5-11400, Corsair Vengeance RGB Pro 2x8GB, WD HDD 3.5", Crucial SDD 2.5", Asus BluRay Drive 5.25").
The power supply comes in a simple box, wrapped in bubble wrap bag without unfortunately any pouch even though it is a B-tier category intended for mid-range and high-end builds. It comes with 7 internal cables (5 of which are detachable) and a classic AC power cable 1.4m long. The internal cables are all short, which means they are not suitable for most full towers.
The overall construction of the PSU unit is of high quality, heavy (1729g), flawless and has 2 non-detachable sleeved cables: 1 for motherboard (20+4pin) 550mm and 1 for CPU (4+4pin) 600mm. The power supply operates flawlessly, I did not notice any restarts or overheating.
The noise of the very good fan is minimal at low and medium loads (up to 560W) at higher loads above 665W, which is prohibited for use, the intensity exceeds 30db. Even when I tested it in demanding rendering, the sound was low and I had to bring my ear close to the back of the case to hear it.
It was tested and passed the compatibility test with APC line-interactive UPS. I will come back with an update on its performance at high loads as soon as I add a graphics card to my system. In this video, I have included measurements of cable/PSU dimensions, fan noise samples, output voltages, and many other tests of the be quiet! 700W power supply: https://www.youtube.com/watch?v=dH5lX180K14
After 2 months of use, I would like to mention a major issue. Because I use it in a noise-free space, I noticed that there is a strange sound coming from the computer. Then I realized that it is coming from the power supply and it surprised me. I do not recommend it if you are in a quiet environment. Otherwise, it is an okay PSU. However, I found it strange that it is not so quiet.
It is very good and worth its money. I believe it can be used not only for a budget build but also for something heavier. It is quiet and I don't think cable management will be a problem for you. It is perfect, but it also depends on who is doing it for all the other things. Words are unnecessary, I highly recommend getting it with closed eyes
Given that power supplies are generally expensive at the moment, I was looking for a power supply with relatively high wattage that could handle a Ryzen 7600x and a 6700 xt, which it has managed to do perfectly so far. It's a quiet PSU, semi-modular, 700 watts, and purchased for 86 euros with decent build quality, considering the current market. It seems fine to me. If anything changes, I will update.
Update 16.01.24: Attention: While playing latest generation games (Baldur's Gate 3), the power supply would occasionally restart because it couldn't handle the load. I replaced it with an 850W Pure Power 12 from the same company and it works flawlessly. So, despite its nominal 700W, this particular PSU cannot handle graphics cards with a requirement of 650W.
New market, currently appears excellent. Under full load with stress tests on both CPU (i5-13600k) and GPU (GTX 3060) simultaneously, I measured a consumption of 600w at 230v, which it handled comfortably without any hiccups. In gaming, the numbers are lower, while in office work and browsing, it is almost silent. If I have any further comments, I will add them.
I have been using it for about a month. It works flawlessly. The box includes everything you will need, from screws to cables. It is completely silent.
Excellent! I trust Be Quiet. I ended up with the 600W for future use of a graphics card.
It is used with ryzen 5 5600g, 2x8gb corsair, SSD EVO 500gb, and flawlessly gigabyte b550 DS3H motherboard.
Silent as if you don't have a computer turned on.
Very good and high-quality power supply. It performs very well even under unstable voltage conditions. It can handle a system with Ryzen 5600, 16GB, GeForce GTX 1660, 4 SSDs, and a professional sound card without any issues.
I have installed it on a PC with an Asus Strix B550, a Ryzen 5 3700, and an RTX 3060Ti. The graphics card and CPU are overclocked without any issues at all! Overall, it is very quiet within the system without any issues with voltages and random restarts.
I installed it and it made an unnatural noise, even more than my old computer's 10-year-old power supply. I sent it back immediately. They acknowledged the problem, without any "yes, but" excuses. In the end, I didn't (re)order this one, but I paid a little extra and got the Be Quiet Pure Power 11 400W, which is Plus Gold and turned out to be fine. The whole situation cost me a week's delay.
What can I say, obviously I came across a black sheep, I don't want to bury the product but I'm stating the facts.
Its installation here: https://youtu.be/kzdZjuLBLmU
10+ months of use without the slightest issue, installed on a system designed for Twitch streaming. Truly quiet even under load, proving that the brand name is not random.
I have had it for 2 years and have had no problems. I got it for 70 euros, but even if it costs 100, it's worth the money. You can put up to three disks and two graphics cards or something else that requires power from the power supply.
I highly recommend this power supply. It is the best value for money PSU on the market. It makes no noise at all and can easily power a budget PC and more.
