Yes — it's ATX 3.1 and PCIe 5.1 compatible, and ships with a 16-pin PCIe cable rated to deliver up to 600W, making it suitable for GeForce RTX 50-series and Radeon RX 9000-series graphics cards.

Is 850W enough power for a high-end gaming or workstation build?
For most single-GPU builds, yes — the PSU supports total power excursions up to twice its rated output and graphics card power excursions up to three times rated power under the ATX 3.1 standard, giving headroom for transient spikes from modern GPUs.

How efficient is this power supply?
It's 80 Plus Gold and Cybenetics Gold certified, delivering up to 92% efficiency, which means less heat output, lower fan noise, and reduced electricity waste compared to lower-tier certified units.

Are the cables fully modular?
Yes — it uses fully modular, tin-plated oxygen-free copper etched cables that are flexible for cable management and run up to 50°C cooler than the UL safety limit.

What cooling does the PSU use, and how long does the fan last?
It uses a 135mm fan on a dual-ball bearing setup, which is rated to last up to twice as long as a sleeve-bearing fan design under continuous operation.

What safety protections does this PSU include?
It includes Over-Power, Over-Voltage, Under-Voltage, Short-Circuit, Over-Current, and Over-Temperature Protection, covering the main failure points that could otherwise damage connected components.

What's included in the box?
The unit ships with a power cord, motherboard power cable, CPU cable, a PCIe Gen 5.1 16-pin cable, additional PCIe cables, SATA cables, a peripheral cable, and a user manual.
