Endorfy's Enduro L6 850W brings ATX 3.1 and PCIe 5.1 support, high efficiency, and a native 12V-2×6 GPU cable to the budget PSU market. But does its non-modular design hold it back?
Budget power supplies rarely meet all the latest standards, but the Endorfy Enduro L6 850W is an exception. It offers full ATX 3.1 and PCIe 5.1 compliance, a native 12V-2×6 GPU cable, and efficiency ratings that rival more expensive models. At €94.90, it's aimed at builders who want modern features and solid performance without overspending.
The Enduro L6 850W is ready for demanding graphics cards, including Nvidia's RTX 4000 and 5000-series, thanks to its 12-pin 12V-2×6 connector that can deliver up to 600W directly to the GPU. The 12V rail is rated for 70A (up to 840W), so it can handle power-hungry cards like the RTX 5080, RTX 5070 Ti, or Radeon RX 9070 XT. For anyone looking to build a system that won't need a PSU upgrade soon, this is a strong contender.
Shops across Europe list the Enduro L6 850W for around €94.85 to €94.90, making it one of the most affordable 850W units with these features. The platform comes from OEM Jiumeng, so it's based on a third-party design rather than being built entirely in-house. This lets Endorfy offer advanced features and certifications-like 80 PLUS Gold and Cybenetics ETA Platinum-at a price that undercuts much of the competition.
Efficiency remains high across typical loads, with the unit achieving Cybenetics Platinum at 230V input-peaking at around 93% efficiency at half load and staying above 90% even at maximum output.
There are some compromises. The Enduro L6 850W uses a non-modular cable setup, so every cable is permanently attached. This can make cable management tricky, especially in smaller cases, since unused wires need to be tucked away. The cooling fan runs all the time, even when the system is idle, and there's no semi-passive or zero-rpm mode. At higher loads, the fan gets noticeably louder, which could be an issue for those sensitive to noise.
Still, the technical performance is solid. Voltage regulation on the main +12V rail is tight, ripple is well controlled, and noise stays low at light to moderate loads. The compact size, black flat ribbon cables, and double-sided PCB give the unit a sturdy feel that doesn't come across as a budget compromise. Full ATX 3.1 and PCIe 5.1 support means it's compatible with the latest hardware, including GPUs that require the new 12V-2×6 connector, as shown in current European listings.
Endorfy includes a seven-year warranty with the Enduro L6 850W, which is rare at this price. That long-term support is reassuring for anyone who expects their PSU to last through several upgrades.
Some budget competitors, like the Thermalright TR-KG750, have struggled to balance modern standards with quiet operation, as reported earlier. The Enduro L6 850W avoids the worst of these issues, offering both efficiency and up-to-date compatibility, though it doesn't fully solve the noise and cable clutter that are common in this segment.
The Enduro L6 850W is a rare budget PSU that delivers on the features most PC builders care about. The lack of modular cables and a silent fan mode may put off those who want a perfectly tidy or ultra-quiet build, but the combination of high efficiency, strong power delivery, and support for new standards at this price is hard to beat. For buyers who value reliability and future-proofing over absolute silence and cable minimalism, this PSU is a standout choice in the sub-€100 range.
