At the face of the box is a photo of the PSU with the model and wattage descriptions. The power specifications, various badges, and icons describing the PSU's compliances and certifications are on the back.


Protection inside the box is mediocre since only a bubble wrap protects the PSU. It would be way better with packing foam surrounding the product.


The bundle includes fixing bolts, zip ties, the user manual, and cables.


The fan grille is not restrictive and makes for a clear look at the fan blades with their airflow-optimized design.


The power specifications label has been put on one of two sides. On the other, we find a stamped logo of the brand.


The modular panel has nine sockets.


160 mm is normal for a 850 W PSU. There are smaller, PSUs of similar capacity, but they are also noisier.


Some more photos of the PSU from various angles.

At just 550 mm, the ATX cable is not that long—It should at least be 600 mm long. The same goes for the EPS cables, which should be 650 mm long. You probably won't have an issue in normal-sized cases, but an 850 W PSU can also be used in larger cases. Lastly, the number of connectors is good. Four PCIe and two EPS connectors are enough for a PSU of this capacity.


There are many SATA connectors, but I would like to have four 4-pin Molex connectors. There is no need for a fixed FDD connector. They should install a Molex connector instead and provide an FDD adapter. The distance between peripheral connectors is ideal, though.
