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.

The name says it all. Quality, performance, and quiet. Handles my AMD Ryzen 7 5800X and GTX 3080 with no problem and with power to spare

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.

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.

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.

Extra power fixed my computer! The old ps I guess had intermittent problems because the computer would stop and say it had to shut down. It gave me 10 different errors, some on youtube, but only one guy said " this could be caused by a bad power supply." Nice and quiet too. Now reloading programs.

It's hard to give an accurate review on PSUs, as almost every single one you buy will work, at least for a short time. I've had mine for a month or so now and haven't had any issues. My system has been running fine with zero stutters. It is worth noting that I am using an Uninterruptible Power Supply as my power gets pretty dirty when I'm running my AC, so your mileage may vary if you're plugged right into the wall. From what I was able to see online, this power supply has great reviews. I definitely wanted to go with fully modular cables, as I hate having the extra bulk. Cables seems high quality and are all black, and the whole unit feels very solid. Again, hard to say long term how this will hold up. I would say check on YouTube and reddit first to see if anyone's had any issues pop up 6+ months after owning, and if there aren't a significant amount of people reporting anything, I'd say go for it.

Works fine and seems like good quality. Quiet. Only gripe is while the cables are just barely long enough for a direct rout to my atx pc connections the cables are way too short for clean routing. Make your cables longer please.
