Model overview based on user reviews
The Chieftec Compact SFX series, including models like the CSN-450C, CSN-550C, and CSN-650C, is praised for its compactness, modular cables, and efficiency. Users appreciate the detachable cables and smart temperature control features. However, a common issue across reviews is the noisy fan, which some users have addressed by replacing it. While some users report excellent performance and reliability, others have experienced serious flaws, such as poor soldering and component issues. Overall, the PSU is suitable for those who can manage or tolerate the noise, with some modifications potentially enhancing its performance.

Disassembled (voided the warranty) and removed the noisy fan, installed a different one in its place, routed the wires outside and connected them to the motherboard to manually set the desired speed. Now it's not noisy at all and doesn't overheat - tested it by running stress tests for half an hour, then turned it off and touched the heatsinks inside with my hands - not hot. Compactness. Power. Modular cables. Cool even under heavy load. Noisy fan. The motherboard power cable is not black like the others. |
Burned 2 motherboards. Complete junk. Upon opening, non-factory soldering was discovered, and all components are soldered crookedly. sizes, bought in mini case Terrible performance |
550W at 3600 and 1070, without overclocking: buzzing, noisy. I highly do not recommend it in the desktop version. It's not so annoying on a shelf or under a table. 80+ Gold, efficiency, cables. Noise, hum.  Sugar Unicorn: use Chieftec CSN-550C few months |
