The Supremo FM6 1000W is a very complete and silent modular power supply. The Endorfy block complies with the latest ATX 3.1 and PCIe 5.1 standards, and features the famous 12V-2×6 connector that supports the latest generation of graphics cards. In addition to a 10-year warranty, this block is 80+ Gold and Cybenetics Platinum certified. Cybenetics has also awarded it an A rating for noise. But the other difference lies in the price, with this block priced at around 145€! Let’s take a closer look at this block. Spoiler: once again, Endorfy treats us to excellent value for money.
Before we go any further, let’s take a look at the video:
Presentation
The Supremo FM6 1000W block complies with the latest ATX 3.1 and PCIe 5.1 standards, perfect for the latest configs, notably with its 12V-2×6 connector that supports the latest generation graphics cards. With its 1000 watts of power, it can handle greedy setups with excellent energy efficiency. Price? Around 145 euros, an aggressive price for this level of quality. As an added bonus, it comes with a 10-year warranty, proof of the brand’s confidence in its product. First contact with this power supply doesn’t really take us away from the rest of the Endorfy range. The same philosophy applies to the design of the packaging: simple, sober, effective. The brand assumes that it puts its money into products, not marketing.
The power pack is secured in the box with bubble wrap. The rest of the space is taken up by additional components and cables. These include a power cord, cable ties, a user guide and mounting screws. Everything you need to integrate the power supply into your system is included. This power supply is 100% modular. This means you’ll find all the cables you need to power your PC. These cables are distinguished by their high quality, both aesthetically and in terms of the wire diameters used. Obviously, we’re not on the same level of detail as Corsair’s RM blocks, but objectively, everything we have here is of excellent quality.
Design :
Like almost all brands selling PC power supplies, Endorfy uses an external manufacturer. When you open the FM6 block, you can see that Endorfy uses SAMA as OEM for the design. However, while some are content to choose an off-the-shelf design and just stick their stickers on, we can see here that some design choices have clearly been made by Endorfy itself.
Once disassembled, we can see that the PCB soldering is very clean and that quality components have been used. Special mention should be made of the primary stage, which is fitted with a high-quality Nichicon capacitor. Nichicon offers quality capacitors, and other Japanese brands such as Nippon Chemi Con and Rubycon can also be found in this block. These are rather high-end capacitors.
Ventilation is provided by the Fluctus 120 mm in-house fan. Even if this block doesn’t operate in “semi-passive” mode (with the fan switched off when the load is low), the Fluctus is a gem, designed to run quietly while cooling efficiently.

Important features
To dig a little deeper, let’s recall once again that the Endorfy Supremo FM6 1000W has been awarded Cybenetics Platinum certification for its efficiency, and an A for its silence. The certification logo does not yet appear on the packaging, but you can find all the details on the Cybenetics website here.
In evaluations carried out at 115 V and 230 V, the power supply revealed an average efficiency of 90.01% at 115 V and 92.18% at 230 V, after being tested on over 1,450 varied load configurations. These results have earned it ETA Platinum certification, making it one of the most efficient power supplies available on the market today. An added bonus is its power factor, which reaches 0.981 at 115 V and 0.941 at 230 V, figures that underline the reliability of its electrical regulation.
Secondly, the unit is equipped with the brand’s Fluctus 120 mm fan. Without exaggeration, we’re repeating ourselves: it’s a gem, and the block’s virtually noiseless operation and efficient cooling contribute to the overall quality of this reference. Another important argument put forward by Endorfy is the use of top-of-the-range Japanese components, a guarantee of reliability and longevity, generally perfect for avoiding unpleasant surprises. Last but not least, it’s armored with protection: overvoltages, short-circuits, overheating, everything goes, securing your configuration and, of course, your graphics card. To be clear, all these elements already make a real difference for a product in this price range.
Conclusion
In conclusion, the Endorfy Supremo FM6 1000W is a power supply that ticks almost all the boxes. Its compatibility with modern standards, energy efficiency, remarkable silence and 10-year warranty make it a solid choice for gamers or those who want something reliable and efficient without having to pay a high price. Yes, its price is its main argument, but frankly, that’s simply a reflection of the quality of the brand’s workmanship… And on this block, it’s truly impressive. Beyond power and modularity, operating comfort changes everything. If you’re building a powerful PC and looking for a long-lasting modular power supply, we can’t recommend it highly enough. For less than 145 euros, you get a well-designed unit, with quality components, quiet operation… A power pack that’s ready to go the distance and stay with you for a long time. So why deprive yourself? Go for the Endorfy Supremo FM6 1000W, your config will thank you!
