PSUs with the ATX 3.1 standard have been missing from Endorfy’s lineup until now, but that changes today. Specifically, with two new models with rated outputs of 850 and 1000 W. These PSUs, designed for high-performance builds, are set to stand out not only for their attractive price but also for their quiet operation and high energy efficiency. Among other features, they come equipped with a 12V-2×6 cable for powering modern graphics cards.
Not only the 16-pin 12V-2×6 connector but also many other parameters are associated with ATX 3.1 power supplies. Many features are shared with the ATX 3.0 standard, which we’ve covered in more detail.
We can confirm that Endorfy has also joined the wave of modern ATX 3.x power supplies. This comes in the form of two models, one with an 850 W output (EY7A012) and the other with a 1 kW output (EY7A011). These power supplies are primarily aimed at high-performance builds, such as those with an exceptionally powerful graphics card. The higher-capacity variant (1000 W) could even handle a GeForce RTX 5090 within its optimal efficiency range.
The 12V-2×6 cable can now be connected directly to the power supply. With older power supplies that may still perform adequately but lack a native 16-pin connector, an adapter must be used. Sometimes this can be an advantage, other times it may not, but that’s not the focus here. The wire gauge for the 16-pin connector cable is defined as AWG16 for the power section—the “critical” part where higher heating occurs. How high this heating gets and at what current load will be answered by detailed testing. In addition to this connector, the power supplies, of course, also feature 6+2-pin connectors and several other connectors (e.g., for CPU power), which utilize not only the strong 12-volt rail but also the weaker 5 V and 3.3 V rails.
The power supply’s efficiency is said to meet the 80 Plus Gold standard, and among the notable parameters are the wire mesh and the use of a Fluctus fan. However, this fan is “only” in a 120-millimeter variant, likely due to Endorfy’s goal of maintaining relatively compact dimensions and above-average compatibility. The power supply body has a depth of 150 mm, which is less than some competing models, especially among high-capacity 1000 W power supplies.
From the available materials, there is also a development graph illustrating fan speed depending on the power supply load. Cooling is passive up to 40% load in both cases, for the 850 W and 1000 W models. The fan only starts spinning at higher loads, reaching around 1240 RPM at maximum. Even at this speed, it shouldn’t be too noisy, though it’s unlikely to be completely silent either. This, however, is subjective, and each user will evaluate it differently.
The Supremo FM6 power supplies also support all safety protections against overvoltage (OVP), undervoltage (UVP), overload (OCP), surge and inrush protection (SIP), short circuit protection (SCP), and over-temperature protection (OTP). When it comes to short-term high current spikes, the ATX 3.x standard is better prepared for them. You can find out how in this thematic article.
The manufacturer’s suggested retail price for the Endorfy Supremo FM6 power supplies is 119 USD (for the lower-capacity 850 W variant) or 145 USD (for the 1000 W variant).
