A Power Supply That Disappears Into Your Build
Here's the thing about power supplies: you don't want them to be exciting. You want them to quietly do their job and never make you think about them again. The be quiet! Pure Power 12 M nails that assignment.
Reviewers consistently highlight how genuinely quiet this PSU runs. The 120mm Silent Wings fan is the star here. If you're building a PC and you've ever heard a power supply fan ramp up during gaming, you know how annoying that can be. This one stays peaceful, even under load. That's not a small thing if you're spending hours in front of your PC.
The build quality is solid across the board. The cables are well-made, the connectors are organized logically, and everything feels like it's built to last. That 10-year warranty isn't just marketing fluff, either. Reviewers note this is a power supply that prioritizes stability and long-term durability over chasing the latest specs.
The fully modular design is practical for real builders. You only connect the cables you need, which keeps your case cleaner and helps airflow. That makes installation easier and your finished build look better.
Now, the honest part: this isn't bleeding-edge technology. It's ATX 3.0, not the newer 3.1 standard, and it's 80+ Gold, not Platinum. But here's the reality for most people building today, that's more than sufficient. The ATX 3.0 connectors work with current and near-future GPUs. The Gold efficiency means you're not wasting power or money. It's practical, not theoretical.
The price is where this really shines. At under $95, you're getting a 750W PSU with a decade warranty, quiet operation, and solid construction. That's genuinely good value. You're not paying premium prices for premium features you don't need.
This is the kind of power supply you buy, install, and then never think about again. Which is exactly what a power supply should be.

A Competent but Unremarkable Mid-Range Choice
be quiet! has built a reputation on doing one thing well: making power supplies that don't annoy you. The Pure Power 12 M 750W delivers on that promise without pretending to be something it isn't.
Let's start with what works. At $95, you're getting a fully modular 750W supply with 80+ Gold certification, a 10-year warranty, and a genuinely quiet 120mm fan. For most mid-range builds, this is sufficient hardware. The construction is solid, cables are decent, and reviewers consistently praise the quiet operation. This isn't a product that's going to embarrass you or fail prematurely.
But here's where I get critical: be quiet! is playing it safe, and at this price point, that's starting to feel like a missed opportunity. The ATX 3.0 standard is already aging. We're seeing ATX 3.1 implementations in newer supplies, and the GPU manufacturers aren't slowing down on power requirements. In 18 months, when you're trying to fit a next-gen high-power GPU into this system, you'll realize you bought a supply that's already obsolete for its intended use case.
The efficiency rating tells the same story. Gold is fine. It's not bad. But Platinum-rated competitors exist in this price range, and the efficiency gap translates directly to higher operating temperatures and slightly more heat in your case. If quiet operation is your priority, that's a reasonable tradeoff. If you're building for performance and longevity, you're leaving money on the table.
The 750W capacity itself is adequate for current systems but getting tight. A single RTX 4090 is pushing 450W alone, leaving only 300W for everything else. That's workable, but it's not generous, and it means you're running closer to max load more often, which accelerates component aging.
Where be quiet! wins is in the warranty and the realistic assessment of what most users need. A decade of coverage is a genuine commitment. The quiet operation isn't marketing fluff. And at $95, the price is right for what you get.
But this is a supply that's optimized for reliability and silence, not performance or future-proofing. It's the right choice if you value stability over cutting-edge specs, which is a valid position. Just don't expect it to wow you or surprise you with technical innovation.
