Style: THOR II|ATX Size: 850W
This power supply is probably more on the expensive because of the extra features like the rgb and the fancy design but it's well worth it in my opinion. It was easy to install with options to install it either upside down or right side up. It comes with way more cables than I will ever need but they are high quality braided cables. They are very long to where you should have no problems with reaching the area they need to go. It seems pretty hefty and durable with what feels like a strong metal casing around it. There is also an option for silent mode but I felt no need to turn it on because it was already super quiet. The only way I knew it was on at first was because of the rgb. ... show more

    • Excellence achieved at all levels
Style: THOR II|ATX Size: 850W
This was the best purchase, I've made in a long time compared to other off brand PSUs out there. It includes every cable you need for GPU and power to other components. The braided type cables made it a snap for cable management. Ease of installation, efficiency when it comes to power saving and being absolutely 100% quiet is great. It's a platinum II 80+ platinum so there's no need to look elsewhere for this 850 watt PSU for your next build. ... show more

    • Excellent all around
Style: THOR II|ATX Size: 850W
I used this in a gaming pc build with an Asus AMD 670e motherboard and Mid atx case (fractal meshify 2 compact), and Nvidia rtx 40xx series graphics card. It included the perfect number of cables for the motherboard and all the VRM’s and had the appropriate 16 pin connector for the video card. The cables are extremely high quality and individually sleeved, and I had a good length and slack when routing. The cables are somewhat stiff, given that they are either solid core or a tightly woven multi strand so I used a highlighter to make tight and smooth bends in tight clearance areas in my case. The PSU is very cool and quiet. I also read multiple reviews which showed that voltages are very stable and precise up to full rated load. I can’t speak to the lighting as the power supply is entirely enclosed in my installation. Also, in my installation, the fan is correctly oriented with regard to outside air in my case. ... show more
