ATX 3.1 power supply for modern builds
This 850 W unit meets the Intel ATX 3.1 specification and includes a native PCIe 5.1 12V-2x6 connector rated for 600 W. It is built for users who need reliable, efficient power for current-generation graphics cards and CPUs. The non-modular design keeps cost down while the flat etched cables help routing in tight spaces.
Upgrade from older ATX 2.x units lacking 12V-2x6
If your existing supply follows the ATX 2.x standard and cannot deliver the 600 W PCIe connector required by newer GPUs, this model closes that gap. The jump is worth it when a graphics card upgrade demands the native 12V-2x6 interface and 850 W continuous output at 40 °C. The 80 Plus Bronze rating and 105 °C main capacitor add efficiency and longevity over many legacy Bronze units.
Check case clearance and cable routing before
The PSU length is 140 mm, so confirm your chassis supports that depth. Because the unit is non-modular, every cable is permanently attached; verify you have room to route the full set, including the flat etched PCIe and ATX leads. Input range covers 100 to 240 V at 50 or 60 Hz, matching standard mains worldwide.

Questions sur cet article
What case clearance does the 140 mm length require?
The unit measures 140 mm long, so any ATX case with at least that depth will accept it without interfering with drive cages or the motherboard tray.
How do I confirm the PCIe 12V-2x6 connector is fully seated?
Push the matcha dual-colored H++ connector until the green band disappears; the colour change shows the latch has engaged and the 600 W link is secure.
When should the 105°C main capacitor be considered for replacement?
The capacitor is rated for 100,000 hours minimum MTBF at 105 °C; plan a preventive swap once the supply approaches that service interval.
