Outdated Product
An affordable "gold" power supply unit with a 650W capacity, suitable for gaming and universal systems, requiring stable power supply and durability. Part of the Chieftec PowerUp line (2021 release), it provides a good reserve on the +12V line, designed for nearly the full declared power and geared towards mid-range builds with processors like the Core i5/i7 and popular mid-range graphics cards such as the GeForce RTX 3060/4060. Priced in the affordable solutions category with an 80+ Gold certification. It occupies the niche between the most budget lines and more expensive Chieftec series, offering the user a practical option without excessive features. Compared to popular models like Chieftec Core and Chieftec Proton, this power supply is distinguished by higher execution and reliability levels...and a more substantial warranty period, hence it is usually chosen by more demanding builders. The circuit design is built on a bridge LLC converter with DC-DC converters, allowing the unit to work confidently under variable loads and maintain stable voltages. High efficiency is confirmed by 80 PLUS Gold, TÜV Rheinland, and Interseroh certifications. The cooling system uses a 120mm rolling bearing fan. The design is intended for longevity and balances performance with noise levels. Cables are in a modular format, easy to manage, with unnecessary ones easily disconnectable. The protection kit covers all major scenarios — from overvoltage and overload to overheating and short circuit. The manufacturer confirms reliability with a five-year warranty.

Model overview based on user reviews  
The Chieftec PowerUp series, particularly the GPX-850FC and GPX-750FC models, offers a compelling choice for those seeking a PSU with an 80+ Gold certification at a reasonable price. Users appreciate the modularity and reputation of the brand, which provides flexibility in cable management. However, there are notable concerns regarding the stiffness and inconvenience of the cables, especially the 24-pin cable, which some users found difficult to insert into the PSU and motherboard. Despite these challenges, the PSU performs quietly under load, even with demanding setups. While the product is generally well-received, potential buyers should be aware of the cable issues and consider replacing them if necessary. Overall, the Chieftec PowerUp series is a solid choice for those prioritizing efficiency and brand reliability, though some may find the price point less appealing unless the GOLD certification is a priority.
Pros

Cons

It seems like a good option, but the cables were very strained and had to be changed

When purchasing, I advise you to immediately change the cable, you will not like it
Price for 80+ Gold
Cables, they are very inconvenient here, stiff. Especially the 24pin cable - long, thick, unbendable, black...
Meluse Chieftec GPX-850FC more than year
very disappointed
1 March 2022 
famous company, modularity
wires and connectors I pricked all my hands while inserting the 24-pin into the PSU and spent a lot of strength The 24-pin does not go into the motherboard until it clicks, and I don’t want to break it I’ll have to do something about this, because the board may burn out

for 5k it would be top for its money, for 6 not so much... Only if the GOLD label is important to you.

I have no idea what to write in the review for the PSU, since essentially it should be written when
1 - There is a power surge and some device gets fried, and it's operating at that moment
2 - Connect a farm closely to 550 and check if the contacts will melt
3 - Lightning strikes)
1060 6GB + 12600K and a bunch of peripherals = no noise
The wires are packed in a bag. Detailed instructions, no complaints about the package, even 2 cables turned out to be unnecessary.

Pure gold

Chieftronic PowerUp is a fully modular 650-watt power supply from Chieftec's gaming sub-brand. Received an 80+ Gold Energy Efficiency Certification. This means an efficiency of up to 92 percent when powered by a 220-volt household power outlet. Able to work PSU and from 110-volt networks.

Chest in orders

Also certified by respected international organizations TUV Rheinland and Interseroh. The first guarantees reliability, and the second — environmental friendliness. Built on the CWT platform, which is traditional for Chieftec products. The output voltage is stabilized according to the progressive DC-DC Load-Line Calibration scheme.

Nothing extra

On the main line, +12 V produces a current of 54 amperes, that is, 100 percent of the total claimed power. The length of the 4 + 4-pin processor cable is 65 cm, which is even with a margin. Graphics card cables 6 + 2-pin are available in two pieces. Extra SATA and Molex wires are offered to be stored in a convenient cloth bag.

defensive reflexes

The 12 cm Yate Loon fan, based on rolling bearing, runs quietly. ChengX and CapXon capacitors, mixed 85 and 105 degrees. There is a varistor for lightning protection. All possible levels of electrical protection are also implemented: from short circuit, power surges, overload and overheating. All of this is backed by an extended 5-year warranty.
