Review: Good PSU - Works as intended. Running a Ryzen 7 5700g and a RTX 3060Ti with no problems under high load.
Review: Great Value Power Supply - So far this power supply has been fantastic. I have previously bought other Thermaltake items, but had never really heard anything about their power supplies. I was looking for a fully modular supply to replace my EVGA 500W because I did not have enough room behind my motherboard tray to install an SSD with all the extra cables from the non-modular EVGA unit and the cable extensions I had on some of the leads. The cables of this unit occupy a relatively tiny amount of room compared to a non-modular unit. I was able to relocate a 3.5 inch hard drive to the back of my case (Fractal Design Nano S) and install the SSD in the front compartment. I was also surprised by the quality of the cloth bag that comes with the power supply to hold any extra cables. The RGB is a nice addition considering the price and all of the other features included, but it isn't the best implementation. The fan LEDs can either slowly cycle through all of its possible colors, display solid red, display solid green, display solid blue, display solid white (which isn't a very pure white, it has a bluish tint to it), or be off. It most definitely cannot display more than one color at once as the product image would suggest. Perhaps in a future version of this power supply a better implementation of the RGB lighting would be to have a long press of the button change between the modes and preset colors (what the short press does now) and allow a short press to pause the color cycle in the mode that slowly changes between all the colors. That way it would be possible for the user to have a wider array of static colors if they do not like any of the presets. As for noise, the power supply is not audible over the other case fans and my CPU cooler. I appreciate the inclusion of the smart-zero fan switch, but I always leave the fan on considering it does not add any noticeable noise and it allows me to use the supply as a secondary exhaust fan for my system. So far the only drawback to this power supply aside from the aforementioned lack of full RGB customization is the red connectors for the PCI power cables and the sheer amount of colors on the stickers on both sides. For a product that claims to have implemented RGB as a way to let the user customize their color scheme, using these colors over black and white just doesn't make sense. Overall, this is a great power supply, especially for the asking price. If you are looking for a power supply that will add that extra little bit of flair to your PC, look no further, this is it.
