Model overview based on user reviews
The Chieftec Smart A8 series offers a range of power supply units (PSUs) with varying wattages, including models like the GPS-600A8, GPS-650A8, and GPS-700A8. Users appreciate the affordable price and quiet operation of these units, with some models providing reliable performance for over a decade. However, there are mixed reviews regarding noise levels, especially under load, and some users have reported issues with cable management and power delivery. The units are generally considered a good value for budget builds, but there are concerns about durability and noise over time. Overall, the Chieftec Smart A8 series is recommended for those seeking a cost-effective solution, though potential buyers should be aware of the possible drawbacks related to noise and long-term reliability.

Durability Loud, the wires are unattractive and stiff.  Egor: use Chieftec GPS-700A8 more than year |
Good block, nothing special. That's what time-tested means! Very quiet and always cold (it truly is cold both in winter and summer, which is a huge plus) I could nitpick that the wires aren't braided, but since the unit is from 2013, I can overlook that. Ruslan: use Chieftec GPS-700A8 few months |
Took a 700-watt power supply for my setup with Ryzen 2700 and GTX 1080. In the system, there is also just 1 SSD and 1 HDD. Everything was fine until I started running benchmarks designed for weaker graphics cards, and this also happens in games where FPS reaches 150 and above (i.e., in all games where the graphics card doesn’t struggle with graphics, although I haven’t tried such games yet, and I think there are very few). The power supply starts to squeak and whine, and both the processor and the graphics card may be almost not loaded, but for some magical reason, the high FPS in applications causes this effect in the power supply. Moreover, the higher the number of frames, the louder and higher the pitch of this squeal. I specifically tried to run something very undemanding with an unlocked frame rate (CS:Source was the first at hand). The system delivered 1200 frames, and the power supply was squealing as if a drill was being used. The only solution I found for myself is to artificially limit the number of frames to 120 where this effect occurs. This doesn’t eliminate the issue, but at least it reduces the squeal to a less noticeable level in the overall background. The unit produces ~ 640 honest watts on a 12 volt line, the cooling is quite quiet Perhaps I got a defective unit, but it whines louder than the women in old horror movies; The cables at the base are tangled (i.e. the cable bundles at the ends are soldered to the ports as needed, but at the exit from the unit, these cables may be tangled, and the only way to untangle them would be to cut off the pins); The cable for the processor is quite short, partly due to the previous problem. In a case with a bottom-mounted unit (Raidmax Gama), I barely managed to stretch it. Mihail: use Chieftec GPS-650A8 less than month |

I've never had any problems with it until recently when I decided to play The Witcher, and it started crashing periodically. After overclocking, it would crash immediately after starting the game. I decided to lower the graphics card frequencies, and the problem was solved. No more crashes. I suspect the PSU because the +12V line sags significantly under load, almost going beyond 5% (down to +11.5~11.4). But, after all, it's already 10 years old.
If I'm mistaken in my conclusions, please correct me - I'd be happy to solve this problem.
