Great 850w Power Supply Unit Highly Recommend
This is a great power supply handled my Ryzen 5 7500F and RTX 5070 Ti with a ton fans and aio. Also has the 12v-2x6 ATX 3.1 connector for my GPU which is nice as well. No problems at all the smart zero fan mode is also nice so it doesn't come on at low loads when it doesn't need to. Cables are nice as well and the psu is nice and compact so it was easy to install in my case which is the Montech XR. It is much better compared to my older unit I use to have it will also allow me to get stronger upgrades for PC parts in future if you need to.

Powerful, quiet, and reliable PSU for demanding builds
The Thermaltake Toughpower GT 750W has been an excellent choice for my build. Right out of the box, you can tell it’s made with high-quality materials—solid construction, sleek design, and well-planned airflow. It’s built to deliver clean, stable power, and it absolutely delivers. I’m currently using it with an RTX 3060, and it’s been flawless at maintaining stable performance even under heavy load. There are no voltage drops or overheating issues, which gives me great peace of mind during long gaming or work sessions. One of the things I appreciate the most is how quiet it is, even when the system is pushed to its limits. Its energy efficiency is also noticeable, and it stays cool at all times thanks to its optimized cooling system. This is definitely a power supply suited for mid to high-end builds—especially if you want something durable, reliable, and backed by a trusted brand. I highly recommend it if you’re looking for true stability and power for your GPU.

Great quality
Absolutely love this PSU. It is really quiet as I have never heard the fans going on it. The quality and cables are amazing. I wanted to try a PSU on the cheaper side, and this is a great option. This PSU is a great deal.

"I Have the Power!"
Nice PSU and Good price. Works as expected, quiet, and all cords have been plenty long enough for my roughly 16 x 16 PC case. This PSU supplies all the power I need and comes with a 12vhpwr cable that works perfect with my 5070 ti GPU.

Been great so far…
Been using PSU for a little over a month. I have had no issues with power delivery. I7-14700k and 4070ti, i do get a small bearing squeal at system start-up but it goes away after 10 mins for that i gave it 4 stars.
