Power and Performance Reviewed
When considering a power supply unit (PSU) for my PC build, the Thermaltake GX3 850W Gold piqued my interest for several reasons:
80 PLUS Gold certification: This means the power supply meets high energy efficiency standards.
PCIe Gen 5.0 connector facilitates the use of modern hardware.
An 850W output is a powerful choice for powering demanding computer builds. With this level of wattage, you can ensure that all components, including high-performance GPUs and CPUs, receive consistent power for optimal performance.
However, no product is perfect. I identified a few potential concerns:
non-modular PSUs come with all cables attached. This can lead to excess clutter if not all cables are used.
This power cable for the device comes with only one 12VHPWR connector. This may restrict setup options for systems requiring multiple PCIe connectors.
From my perspective, the Fluid Dynamic Bearing Fan is commendable due to its low noise levels. This feature is beneficial for those who are easily disturbed by fan sounds, particularly in quiet work settings. The fan boasts industrial-grade protections like Over Voltage Protection (OVP) and Short Circuit Protection (SCP), ensuring component safety from electrical irregularities.
Adhering to Intel’s stringent ATX 3.0 specification, this high-performance power supply is designed to deliver an impressive 850W output. Suitable for a range of PC configurations, from demanding high-end gaming setups to complex workstations equipped with numerous storage solutions, Intel’s ATX 3.0 specification ensures efficient power management and catering to diverse requirements.
From a user’s perspective, the power supply’s high wattage allows for future upgrades without concern. Despite its non-modular design which may not appeal to those preferring a tidy internal look or compact cases, the soft black cabling with sleeve design helps manage cables effectively.
On the topic of the single 12VHPWR connector, some users may find it limiting for setups that include multiple graphics cards or require additional connectors. If this is a concern for your needs, you might need to consider power supplies with more flexible connection options instead of the GX3 series.
In summary, the Thermaltake GX3 850W Gold PSU is a solid performer in terms of efficiency, quiet operation, and protective features. While the non-modularity and single 12VHPWR connector might be downsides for some, the overall long-term benefits and robustness could outweigh these issues for most users. The GX3 series seems well-aligned with the needs of modern PC builds and future-proofing considerations.
Compatibility and Installation
When selecting a power supply unit (PSU) for your PC build or upgrade, the Thermaltake GX3 850W Gold stands out for its notable compatibility and non-modular design.
Intel’s ATX 3.0 specifications compliant makes it future-proof.
PCIe Gen 5.0 connector ready, supporting the 12VHPWR standard.
This item showcases an effective sleeve cabling design for efficient cable management.
Let’s delve right into the compatibility of the GX3. It checks all the boxes for a modern PSU—850 watts is more than sufficient for high-end builds, and PCIe Gen 5.0 readiness means it’s prepped for the newest GPUs. The into consideration, I am confident it can support a feature-rich system without requiring an immediate upgrade when new technologies emerge.
During installation, the non-modular design may cause issues with cable management. The excess cables could lead to clutter. However, the flat and black sleeved cables are visually appealing and appear durable. Eliminating separate modular cables might simplify the setup process for some users.
I value the native PCIe Gen 5.0 connector integrated into the PSU, ensuring compatibility with the latest Intel ATX 3.0 specifications. This feature is crucial for potential upgrades to next-generation GPUs, allowing me to utilize maximum power using a single 12VHPWR cable.
A slight drawback of the PSU’s fixed cables is their potential inconvenience for custom builds. These cables may limit CPU choices and overclocking possibilities due to specific length or cable count requirements. However, the cable length is sufficient for medium-sized cases. In my setup, I was able to make the connection without difficulty.
In summary, the Thermaltake GX3 Gold PSU offers a good blend of current requirements and future-proofing capabilities. It may lack modular design customization, but its robust features and specifications make it a solid choice for those seeking a dependable and compatible power source for their PC.
Pros:
High wattage for demanding systems
Compliance with Intel ATX 3.0
This device features a PCIe Gen 5.0 connector for compatibility with future technologies.
Cons:
A non-modular design can lead to excessive cable clutter.
Fixed cable lengths limit options.
Design and Features
Understanding the design and features of a power supply unit is essential for building and using a computer effectively. The Thermaltake GX3 850W Gold has notable attributes but may fall short in certain areas for specific users.
Let’s start with the positives:
80 PLUS Gold certification: This guarantees energy efficiency during power supply operations.
A Non-modular design may streamline your product, but it could lead to an excess of unnecessary cables inside your case.
ATX 12V 3.0 and PCIe Gen 5.0 ready, signifying it’s prepared for future tech developments.
120mm Fluid Dynamic Bearing Fan: This fan ensures quiet and efficient cooling.
However, I have reservations to share. Here’s why:
The non-modular cable design can lead to cable management challenges, especially in cases where space is at a premium.
Sleeved cables aren’t preferred by some when using clear cases due to a minimalist design preference.
If you’re using multiple GPUs or other PCIe devices, a single 12VHPWR cable may not be enough.
Transitioning to its built-in protections, the GX3 series is robust, with safeguards against over-voltage, under-voltage, over-current, over-power, over-temperature, and short-circuiting. These are critical for the longevity of the PSU and the safety of my other components. Bearing in mind these protections, there’s a reassurance that comes with using the GX3 that’s hard to quantify but much appreciated in any build.
The 120mm Fluid Dynamic Bearing Fan is a notable feature. Designed to decrease friction, it leads to less noise. This aspect is advantageous during extended gaming hours or demanding tasks where undisturbed focus is essential.
When it comes to setting up an audio-visual system, many people make a choice of all-black cables due to their discretion and ability to blend seamlessly with other components. However, this preference might pose a limitation for those who value color coordination or themed designs. This isn’t a major concern for everyone, but it’s worth considering as part of the overall aesthetic planning process.
A final note on its size: The dimensions are typical, suitable for most mid-sized cases. But check measurements carefully if using a smaller case.
In short, the Thermaltake GX3 850W Gold PSU brings to the table a mixture of efficiency, future-proof design, and dependable protections, though with a few compromises, such as cable management and aesthetic limitations. Overall, for a PSU that sits within a pragmatic budget without sacrificing essential features, it’s on my recommended list.
Value for Money
When evaluating the Thermaltake GX3 850W Gold PSU, I consider its strengths against minor weaknesses. This power supply delivers good performance and includes features suitable for current and future hardware needs.
