In an i7 14700 | ASRock Riptide Z790 WiFi, Fairly Decked Out Computer
It’s been 12 years since I built myself a new machine, so I felt like I deserved to do it right. After all kinds of research and shopping, I decided on this P/S. (Pure Power 12 M 750W, ATX 3.0, 80 Plus Gold.) I wanted gold, I wanted modular, and I wanted a hundred or two extra watts. I had some trouble figuring out which power connectors went where on the motherboard. (Two 8 pin plugs on the motherboard and one 8 pin connector on the video card.) I called their tech support, it got answered almost immediately by a nice lady who, to my surprise, knew exactly what was going on once I told her which power supply I had! That’s not as easy as it sounds, since, all the different Pure Power supplies come with different sets of (modular) cables; she had a lot to remember! We figured it out in no time and she kept me from potentially plugging one of the motherboard 8 pin connectors into the video card and vice versa. ASRock and Pure Power had totally different names for them. One of the most pleasant tech support calls I’ve ever been on!So, this power supply has been working in this machine for over a month. I’ve had the machine stressed on purpose, testing with CPU Z and and stressed incidentally, up-scaling (from 480P to 720P) and converting (from MP4 to MKV H265) video files. This was a real pleasure! Files that took my old machine over an hour, took 4-6 minutes on this one! Never any trouble, let alone with the power supply. I tried to find the “knee” in the performance to price ratio curve for all these parts, and if I did it anywhere, I did it with this power supply! The computer has 48 gigabytes (2X24) of G.Skill Ripjaws memory. This machine also has 5 M2 SSD’s (One is PCI 5), a SATA 3 SSD, and two 6 terabyte (left over from NAS’s) SATA 3 Seagate Iron Wolf HDD’s. For video, it’s got a used Zotac 1660 6GB GDDR5 card. I’m not a gamer; more of a productivity guy, but this machine’s pretty decked out and it’s faaast, and there’s never any kind of a problem with this power supply! Oh! Yea! No LED’s. The motherboard has them and has an LED controller, but I turned them off. The fans’ LED’s aren’t plugged in. But it has two PWM fans for the processor cooler and 6 PWM case fans – the smallest is 120 mm.It boots in under 15 seconds, with all kinds of stuff running, and the cooling fans also crank up as it’s booting, as it shuts down, for a second, and once in awhile for no apparent reason. All the other fans are louder (only when it’s stressed) than the power supply fan, which I never even hear.I recommend it completely. It’s well-built, competent, reliable, (so far; you never know for sure), and quiet, and it has great tech support if you need it. It’s beefy and heavy, but not monstrously huge. It’s very well priced for a “serious” power supply. Perfect! It’s in a Phanteks Enthoo case with plenty of room, so the [modular] wiring is all well laid out inside. I found the included wiring harnesses long enough and sufficient for this build. This power supply finished off a very nice machine! I can’t imagine needing a bigger power supply than this unless you’ve got a gamer-style, several thousand dollar video card or something.
Thoughtfully designed and well-made
This PSU is just a joy to work with. It’s thoughtfully designed and well-built.It feels sturdy without being bulky, the cables have braided sheaths, the PCIe connector is doublewide so you can hook up a 2x8pin GPU to two dedicated lines without needing two dedicated cables so there’s less clutter, and both connector orientations are available on the SATA rails for different drive mounting options.Plus, it doesn’t whine like my Corsair CX750M. In fact, it’s whisper quiet.The cables might be a bit short if you have an XL case, but it fits perfectly in the Fractal North.Highly recommended.
Amazing PSU
This power supply is a beast – quiet, cool, and quality. First time buying from Be Quiet! and I’m really impressed. Installation was a breeze and cables are very easy to manage. I wish the cables felt a little more quality because they are quite ugly and are not braided. Personally I feel like braided PSUs feel better and will last longer, but maybe that’s just me. It’s not a deal breaker, just a pet peeve. The fan doesn’t get loud, honestly I can’t even tell when my computer is even on sometimes. Keeps my GPU and fans running solid when running games. I’m using an intel 7-13700KF, NVIDIA GeForce RTX 4060 Ti, 32G of Ram and this thing runs great with room to upgrade later on!As for the lifespan, I can’t say for sure since I’ve had it running for about a week, but I’ve heard good things about this PSU. I’ve been on a quiet PSU hunt for a good month now, and I can say this is the winner. Really happy with my purchase.
Great PSU.
So far so good. Great PSU. Was having issues with my old Corsair ax1200i after it sat in storage for about 6 years. I decided to switch up my build and change cases so I went from a Lian Li 011 mini to a SUP01 and the Cooler Master sfx PSU I was using wouldn’t fit so I drug out the old Corsair and it would cause a hard crash when my 7900XTX was under full load. Ordered this to replace it and has been good ever since. PSU is quiet under load and provides plenty of power. Also like the fact that even though the pcie cables are dual 8pin, the design of the PSU provides full wattage to both ends of the single dual 8pin.
Great looking fully modular power supply
This power supply is fully modular, so running cables in your case is very easy. The cables are also all black and very high quality. My completed build definitely looks a lot cleaner and prettier without the ketchup and mustard colored cables. The psu is extremely quiet, and it’s worked flawlessly for over 5 months now. I have yet to try a Be Quiet product that hasn’t been well built and reliable.
The power supply looks well built and it did work but there are a few issues.1. The supplied Motherboard and PCIe cables are very short. If you have a larger case the cable may not reach or the cable management will be an issue. 3 inches longer would have been great in my case. Anything to save a penny I guess.2. The motherboard cable that plugs into the PSU puts a lot of pressure on the wires because it’s split. Just a poor design.3. Poor instructions. The cable is labelled one thing and the PSU has it labelled something else. No reason for this.I will update after further testing.
La compré para reemplazar una vertex 1200w platino que falló a los 10 meses, esta lleva 4 meses apenas.El rendimiento es excelente, el ruido es igual a la otra, el consumo energético es ligeramente mayor por que esta es gold vs la platino. Ahora bien es una gran opción en cuanto a los picos de consumo que tiene mi 4090 STRIX, y por la mitad del precio de la otra además de estar en la PSU Tier list y haber tenido una review de overclockers y guru3d y tiene puntajes altos
It delivers what it promises. Puts out good power and is quiet. I’m not sure the fan spins up at all under low load.I’d like if some of the included cables were a bit longer, but they were all long enough to do the job.
Be Quiet is a German brand that offers high quality computer products. They design their cases, fans, and power supplies to be quiet so when building a computer system it remains as silent as possible. This power supply is extremely quiet when running and comes with plenty of cables and accessories and has more than enough power for the most demanding computer build. I have used this power supply and a be quiet case and my system is extremely quiet when operating.
