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.

The unit is Quiet and Effective!
I loved everything about the PSU. It performes AMAZING with very little noise. I believe it tested at 25 db total under load! The modular design is slick. only downside is the cables are NOT flat. Overall its the best I Could find for Value AND QUALITY.5/5

Wish cables were a bit better
Just installed this PSU into an Corsair 275R mid-tower case. The motherboard cable was just barely long enough. I will probably get some extenders at some point as I am worried that the stress of the connection could cause issues at some point. Also the cables are very rigid and “plasticky” which makes routing a little bit of a pain. I have installed dozens of power supplies in my time and have never had this type of issue before. The unit itself seems very well made. Installed this in a 7600X3D/RX 7700 XT build. Was using an EVGA 500w unit which was very solid but I was worried about reaching max wattage. This gives me more headroom and some future proofing.

Great power supply
Amazing item. Very quiet, as promised, and was designed very well. My build required a weird orientation, but this has ventilation from multiple directions and easily accommodated that. It stays quite cool while being quiet. I couldn’t be happier.

La eficiencia y la calidad de suministro son exáctamente lo que uno esperarÃa de un producto fabricado en Alemania. Excelente!

5/5 because I don’t care the cables are short. I knew that before buying. But it probably matters to some people. If you have a WINDOWED case this is probably not for you.QUIET. Fan alway spins but it’s not even audible at roughly half load (around 425 Watts).UPDATE: fan started making a vibrating noise at all times

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.

Esta me decidà a comprarla gracias a un review de guru3d (famosa página web), muy bonita, se siente y se ve de calidad, muy muy silenciosa. Fácil unos 5 años no requeriré cambiar de fuente. Es ATX 3.0, trae el nuevo conector para tarjetas de video con alta demanda energética
