I took a 650W for a system with R5 5600 + RTX 4060. Installed it without problems, except for the very tight fit of all the cables, especially the largest 24 pin (visible in the photo). I was pushing with all my strength, the board and the case were bending)) I was already thinking it might crack, went to a specialist, and he said, "Well, what do you expect, it's new," but a friend recently built a PC with a PSU from Gigabyte and all the cables plugged in easily. I saw reviews that some people didn't have enough cable length, but my case is mATX format, and I didn't experience this issue, maybe it's from users with ATX boards and consequently larger cases. Otherwise, I have no complaints about the PSU, it's been working for a little over 2 months without issues. Long-term warranty Quiet Reliable Modular If you have a large case for full-sized ATX boards, the length of the native wires might not be sufficient. Be careful. The 24-pin plug inserts very tightly, but this might be a motherboard issue.  Sergiy: use be quiet! BN342 few months |
I recommend it as a good model! Silence in the robot 93% FCC (up to 92.6% FCC), modular design, important, subtle components in the middle. The next day, the screen is like a bi showing the speed of the PC at a given moment.  PHOTO-PR: use be quiet! BN343 few months |
Good power supply, Ale came with a broken seal, it’s not acceptable, No guarantees now, I don’t recommend before buying Modular wiring system Broken seal Nubloyid 002: use be quiet! BN342 less than month |

Quiet and modern power supply with support for ATX 3.0 and PCIe 5.0
The Pure Power 12 M is a high-performance power supply that is ATX 3.0 compliant and 80 Plus Gold certified, delivering 93% power efficiency. It supports the PCIe 5.0 standard and is equipped with a 12VHPWR connector, necessary to power GeForce 4000 series video cards.
10 years warranty
The Pure Power 12 M circuitry is based on the HEC platform with LLC topology, half-bridge converter, synchronous rectifier and DC-DC converters. The power units use Teapo solid capacitors and German-made transistors. This filling provides an efficiency of more than 93% with voltage deviations of no more than 2%, meeting 80+ Gold standards. The only negative is the lack of Japanese capacitors, which may disappoint demanding users. However, the 10-year warranty from the manufacturer covers this drawback. If the components were causing serious problems, the manufacturer would not offer such a long warranty.
Under reliable protection
The Pure Wings 2's internal fan automatically adjusts its rotation speed depending on the device's temperature, and the maximum noise level at full load does not exceed 26 dB. Pure Power 12 M has two 12V lines with load sharing, all cables are modular. The security system includes all main types of protection: overheating, short circuit, overvoltage, etc.
