Chieftec A-90 GDP-650C
 | Outdated Product The model is positioned by the manufacturer in the middle price range and can serve as a good choice for powering a powerful and performant gaming computer. So, this model has operational characteristics at the level of "80 PLUS GOLD". But the power supply did not pass independent certification, which explains that the Chieftec A-90 GDP-650C belongs to the most affordable price range (in the “80 PLUS GOLD” category). The efficiency of this model is excellent 90%. The operation of the power supply is built on the basis of innovative DC-DC voltage conversion technology. Circuitry of this type can be safely trusted to supply expensive and performant components.

The wires of t...his PSU model have a semi-modular principle of the device: the power wiring of the motherboard and the processor is non-removable, but all other wires can be used as needed. The active cooling system is represented by a 140 mm fan. The speed of rotation of the impeller depends on the load level. This PSU has an older modification, its rated power is 750 watts. |

Efficiency at the level of 90%. Such high efficiency at the level of certified 80 PLUS Gold power supplies. However, this power supply is not certified.

Model overview based on user reviews
The Chieftec A-90 series, including models like the GDP-550C and GDP-750C, is generally well-regarded for its 80+ Gold certification, semi-modular design, and reliable power delivery. Users appreciate the quiet operation and secure cable connections, with cables being long enough for neat arrangement. However, there are consistent complaints about the stock fan's noise, with some recommending an immediate replacement for a quieter experience. The PSU is praised for its robust build quality and comprehensive protection features like Over Voltage Protection and Short Circuit Protection. While some users experienced issues like burnout after extended use, others found it to be a great value for money, maintaining performance even during power fluctuations. Overall, the Chieftec A-90 series is a solid choice for those seeking a reliable PSU, though potential buyers might consider upgrading the fan for optimal performance.

As for me, this unit is just awesome! I didn't even think it was this good! Sometimes there are voltage spikes at home, everything shuts down, all the TVs turn off, even the router restarts, but the computer keeps running! Over Voltage Protection (OVP) Over Power Protection (OPP) Short Circuit Protection (SCP) I'll say no! |
I will compare it with my previous PSU from the Gamemax GE series. It's clear that Gamemax is much lower in price and quality, but still, you need something to compare it with. And comparing with something you haven't had hands-on experience with is foolish, wouldn't you agree? The internals of the PSU: Gamemax is not a competitor in terms of components here at all. And I'm not much of an expert in all these transistors, transformers, and resistors. So, I'll just comment on the previous one's usage. The Chinese-made Gamemax fully lived through its warranty period, which is really good, but towards the end, the PSU completely lost its efficiency certification and barely output 300W of the claimed 500W (400W on the 12V line). ~~damn, this is turning into a Gamemax review :D ~~ The Chieftec, on the other hand, is much more powerful at 750W (744W (!!!) on the 12V line), has a higher-ranking efficiency certification, and judging by online reviews, promises to maintain all this until the end of the warranty period and even beyond. (Of course, I saw a review where one buyer's fan started rattling after 1.5 years, but it seems that this is a unique case for that particular model.) A large number of protections. Semi-modular. Quiet. Good value for money. Easily delivers the stated power. Fan with a sleeve instead of a bearing. The wire wrapping feels like it’s been remelted from plastic bottles and is unpleasant to the touch. Stiff wires, difficult to manage with cable management. The very hard plastic of the power connectors gives the impression that it could snap off from impact or careless use.  Sergey Denis: use Chieftec GDP-750C less than month |
the unit itself is good, certified 80+ gold, semi-modular, which is good by the way, the cables are not very rigid, so they are quite comfortable Certificate 80+ gold, semi-modular, honest 750W the fan needs to be replaced immediately, after one turn on it starts to make a hum and a slight crackling sound, which is not pleasant oleg: use Chieftec GDP-550C less than month |
