Pros
- Achieves up to 92.7% efficiency with 80 PLUS Gold certification, reducing power consumption and heat output.
- Includes a native 12V-2x6 connector for PCIe 5.1 GPUs and two additional PCIe 6+2-pin connectors for current-gen cards.
- Handles power excursions up to double its 650W rated power, ensuring stability for demanding components.
- Features a temperature-controlled 120mm be quiet! fan with airflow-optimized blades for quiet operation.
- Backed by a 10-year manufacturer's warranty, indicating long-term reliability.
- Maintains tight voltage regulation on 12V, 3.3V, and 5V rails due to LLC technology.
Cons
- The power supply is non-modular, meaning all cables are permanently attached, potentially complicating cable management in smaller cases.
- High-load acoustics might be noticeable, potentially deterring users prioritizing absolute silence under heavy system stress.
- Maximum operating temperature is 40 degrees Celsius, which is standard but not suited for extremely hot environments without additional cooling.
Dimension Scores
The 80 PLUS Gold certification with up to 92.7% efficiency is above average for its price band, and its ability to handle power excursions up to double its rated power is a significant advantage.
The temperature-controlled 120mm be quiet! fan is designed for quiet operation, providing low noise under moderate loads.
The 10-year warranty, LLC topology for voltage regulation, and HEC/Compucase OEM suggest a focus on durability and stable performance.
Being a non-modular power supply means all cables are permanently attached, which can make cable management challenging, especially in smaller cases.
Best For
- Building a new PC with a mid-range GPU that requires a 12V-2x6 connector.
- Upgrading an existing gaming or media creation PC that needs ATX 3.1 and PCIe 5.1 support.
- Users prioritizing lower electricity bills and less heat generation due to 92.7% efficiency.
- Systems where low noise levels are a priority under moderate loads.
Not Recommended For
- High-end gaming rigs with multiple power-hungry GPUs or extreme overclocking, which may exceed 650W.
- Small form factor (SFF) PC builds where a non-modular PSU can make cable routing difficult.
- Users who demand absolute silence even under 100% load.
Watch Out For
- The non-modular cable design means you'll have extra cables to hide even if you don't use them, which can be a pain for clean builds.
- While quiet at moderate loads, some users might notice increased fan noise when the system is pushed to its limits, as mentioned in a review about 'high-load acoustics'.
- The 40-degree Celsius maximum operating temperature means you need to ensure adequate case airflow, especially if your PC components run hot.

What Buyers Say
What really stands out is how many people on Reddit just call this a 'good PSU' without much fanfare, which for a power supply is actually high praise because it means it just works without issues. The 10-year warranty and ATX 3.1/PCIe 5.1 support are frequently mentioned as key selling points, making it feel future-proof. The main drawback is the non-modular design, which can be a headache for keeping a tidy build. It's generally quiet, but a few reviews hint that under extreme load, you might hear the fan.
“Dude, this PSU just works, no drama, no weird noises, and it's ready for my next GPU. Only thing is all these extra cables I gotta shove somewhere, but whatever, it's solid.”
Common Praise
- The 80 PLUS Gold efficiency rating actually translates to lower power bills.
- Native 12V-2x6 connector for new GPUs is a huge plus for compatibility.
- The 120mm fan keeps things quiet during normal use.
- Handles power spikes from graphics cards without breaking a sweat.
- The 10-year warranty makes you feel secure about the purchase.
- Voltage regulation is consistently tight across all rails.
Common Complaints
- Non-modular cables create a mess inside the case if you don't use all of them.
- Fan noise can become noticeable when the system is under heavy load.
- Some users found the black sleeved cables a bit stiff for routing.
Ownership Tips
- The fan really is barely audible during web browsing or light gaming sessions.
- Those black sleeved cables look pretty clean, but they're not super flexible for tight bends.
- Even with a demanding game running, the system stays stable, no weird reboots or anything.
- The 12V-2x6 cable feels robust and clicks securely into the GPU.
- You'll definitely need some zip ties for the unused cables if you want a tidy build.
Frequently Asked Questions

What is the efficiency rating of this power supply?
It is 80 PLUS Gold certified with an efficiency rating of up to 92.7%.
Buying Guide
When you're picking a power supply, you're basically choosing the heart of your PC. It needs to deliver enough stable power to all your components without overheating or making a racket. You need to match its wattage to your system's needs, and consider its efficiency rating, which tells you how much power it wastes as heat. Also, think about the connectors it has, especially for modern graphics cards, and how easy it is to manage the cables inside your case.
Wattage (650W)
This is the total power your PSU can supply. Think of it like the horsepower of a car; you need enough to get where you're going, but too much is just wasted money and potentially less efficient. 650W is enough for most single-GPU gaming PCs without extreme overclocking.
80 PLUS Gold (up to 92.7% efficiency)
This certification indicates how efficiently the PSU converts AC power from your wall socket into DC power for your components. Gold means it's at least 87% efficient at 20% load, 90% at 50% load, and 87% at 100% load. Higher efficiency means less wasted electricity, less heat generated, and potentially a quieter fan.
ATX 3.1 / PCIe 5.1 with 12V-2x6 connector
This is about future compatibility. ATX 3.1 is the latest standard for power supplies, and PCIe 5.1 with the 12V-2x6 connector is specifically designed for the newest, most power-hungry graphics cards. If you're buying a new GPU or planning to in the next few years, this connector is crucial.
Non-modular
This refers to the cables. A non-modular PSU has all its cables permanently attached. This can make your PC build look messy and restrict airflow if you have many unused cables. Modular PSUs let you attach only the cables you need, which is much tidier.
Alternatives
If you need a tidier build, look for a fully modular power supply. For higher-end systems or extreme overclocking, search for PSUs with 750W or greater wattage and a higher efficiency rating like 80 PLUS Platinum or Titanium.
