be quiet! BN513 Pure Power 12 M 1200W Modular Quiet Power Supply | 80 Plus Gold | ATX 3.1 | for PCIe 5.0 GPUs and GPUs with 6+2 pin connectors | Silent 120mm Fan | BN513

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.

It does what it needs to do...the fan Silent Wings fan that is barely audible. The prices of PSUs are a bit right, but this is solid on sale. The fully modular design is nice...my only issue is that the 12V-vhpwr connector doesn't feel like it locks into the PSU, but that's more on the the connector design for 12V-vhpwr. It has a good warranty, so hopefully it lasts at least 7 years like my old Corsair 650w.
