Model overview based on user reviews  
The Chieftec Proton series offers a range of power supply units (PSUs) that are generally well-received for their affordable price and quiet operation. Users appreciate the efficiency and quality of cables, with many noting the modular design as a significant advantage. The PSUs come with Bronze certification and include all types of protection, making them suitable for budget to mid-range builds. However, some users have reported issues with short cables, particularly for ATX cases with bottom-mounted power supplies, and a few have experienced whistling noises during stress tests. Despite these minor drawbacks, the Chieftec Proton series is considered a reliable choice for those seeking a cost-effective PSU with decent performance.

Chieftec does it right
12 May 2021 
On my previous computer, I also had a Chieftec APS-750C, worked flawlessly for 9 years and still running, satisfied with the brand.

The 4+4 pin CPU power cable is somewhat short, I had to stretch it directly as there's not enough for cable management. The cables are closely fitted to the HDD bay, but it's tolerable in the Aerocool Aero One Frost case.
use Chieftec Proton month or more i recommend it should buy
great model, love it
16 October 2020 
I’ve been using it for almost three years, at first it was on a mining farm, 4 1060 video cards and a processor were powered from it, now it’s in my home computer, it works well, I bought it in January 2018 for 90 € for a computer neververse, the wires are long
-Long cables
No
use Chieftec BDF-850C more than year
Got to have it
8 July 2020 
In my opinion, it's the best one, both 500 and 600 can handle any mid-budget build with a graphics card UP TO 2070 super. Got it for 4k rubles.
I was considering the be quiet! System Power 9 (same price), but something bothered me as its graphics card support is only up to 24A, whereas here it's 50A. Although the reviews are also okay, I have a feeling they might be inflated, it's be quiet! after all.

Thick and black wires, clearly no cost-cutting, some in braided sleeves.
I didn't see it. Many people write that the short wires for standard ATX cases with a bottom-mounted power supply are nothing like that. Photo as an attachment.

Available "Bronze"

In 2017, Chieftec released a new line of 7 Proton PSUs, where three of the younger models carry the prefix "S", and the four older models have the designation "C", which means a fully modular cable system. Otherwise, they have a lot in common: compliance with the 80 PLUS Bronze certificate, the power of the +12 V line is equal to the nominal value of the entire PSU, modern circuitry based on DC-DC converters is used, and the entire range of available protections (SIP, UVP, OCP, OTP, AFC).

Almost perfect middle class

In tests, this model proved to be a solid five. With test loads, the voltage on the +12 V, +5 V and +3.3 V power lines remained in excellent condition, the ripples were barely noticeable, and the voltage did not sag even when connected to a PC with a powerful hardware configuration. Also pleased with his tact and unobtrusiveness. Up to the 100W mark, the Proton BDF-500S is very quiet. Between 100 and 250 watts, it can be described as quiet. Above a load of 250W, the sound from the fan becomes more audible, but remains at a comfortable below-average level.

The case when it is worth overpaying

All in all, this is a great mid-range transitional model for those who don't want to overpay for Gold-certified models, but also don't plan to save $20 for cutting everything and everything, as is always the case with inexpensive power supplies. It will easily pull a configuration with a powerful processor and a voracious graphics card of the RX 5600 XT caliber, moreover, without drawdowns below the nominal value of the output lines. And to find something better for the money will be quite difficult.
