    Brand New- Didn't Work

    We bought this power supply brand new out of the box and tried installing it ourselves. We couldn't get it to turn on at all. We ended up taking it to our local computer repair shop to see if they were any more successful. They could not get our computer to power on using this supply either. Unfortunately at that point we were past the 2 week return window, so we are out the money. The repair shop was able to order a working supply for us, and when we went to pick up our computer, they mentioned they tested this supply separately to figure out if the problem was our computer or the power supply itself, and it almost fried the testing device! Not sure how this device managed to have enough juice to burn the testing device, but couldn't power on at all when (attempted)installed in an actual computer.

    I had this power supply unit (PSU) installed in my computer for only two days, and it already failed catastrophically. Last night, while I was using my computer, I suddenly heard a loud pop and immediately smelled something burning. It was alarming and quite disappointing, to say the least. This PSU is extremely unreliable and, based on my experience, I cannot recommend it to anyone. The power supply is a critical component of any computer system, responsible for delivering stable and reliable power to all other components. When it fails, it can cause significant damage not just to itself but potentially to other parts of the computer as well. In my case, the failure of the PSU was sudden and severe, raising serious concerns about its quality and safety. The smell of burning electronics is particularly concerning because it indicates that some component within the PSU overheated or short-circuited. Such failures can sometimes lead to fires, posing a significant hazard not only to the computer but also to the surrounding environment and anyone nearby. When choosing a PSU, it’s essential to opt for a reliable and reputable brand known for quality and safety standards. Unfortunately, this particular PSU did not live up to those standards. If you’re in the market for a new power supply, I strongly advise looking elsewhere to avoid the risk of a similar failure.

    I purchased this power supply for a GPU upgrade, and it worked well at first. However, it failed completely after just 25 days. Since Best Buy’s 15-day return window had passed, I had to go through Thermaltake’s RMA process, where I have now been waiting nearly a month with little communication and no clear update.

    The psu handles most mid range setups the semi modular helps keep cable management low and easy by only using the needed wires. recommended looking up what psu you need for your set up especially if you are going to upgrade in the future

    It died after 3 months running a AMD 6600 XT 8GB card, AMD Ryzen 7 3700X on a Asrock B450 motherboard. I’ve ran a Powerspec 550 watt PSU on a 580 OC 8GB for years, I should’ve just went to Microcenter and picked up a Powerspec 850 instead of door dashing this poor quality PSU, this has 1.2 stars on real Tech retail stores.
