Awesome
Great power supply. Currently in my 12700K + RTX 3060 build. I dont notice the noise at all and has future proof connectors as well. Includes every cable you'll ever need.

Llegó en perfectas condiciones, es igual a las imágenes :D
Me llegó en perfectas condiciones, lo único es que la caja llegó solo un poco golpeada pero la fuente está intacta, pero eso ya es culpa de la mensajería.Aún no la pruebo, pero apenas la coloque en la computadora haré una actualización, por ahora todo llegó correctamente ✨Igual ahí dejo imágenes de la fuente y las cosas que trae :3

Great PSU but I received a malfunctioning one at first
I got this and had problems with it whining and my computer would crash a lot. I ended up having it RMA'd and Thermaltake sent me a higher wattage one for free. That one works great but I was going crazy thinking I built the computer incorrectly. It comes with a ton of modular cables, bags of them and the new one runs very quiet. The fan stays off the majority of the time.

All the right connectors at a great price
Wanted to upgrade my Nvidia graphics card and I needed a new power supply with enough power to run it and also have the 12 pin connector so my card connects right. I have used Thermaltake PSUs before so I knew this would be exactly what I needed. Great brand at a great price! Just remember, if you are changing your PSU you need to use the cables that came with it. Don't use what you had because not all cables are wired the same.

Unreliable, pick something else
Unfortunately, I don't have anything good to say about this power supply. Worked fine for about 3 weeks and then suddenly up and died in the middle of a gaming session. No warning, no loose cables/connections, and no possible way that I was hitting the 850 watt power limit. Unit simply turned off, shut off my PC uncommanded, and refused to power back up. At first I was sure something had malfunctioned with my motherboard, but nope; hooked up my old 800 watt Cooler Master PSU that this unit was supposed to replace, and the whole system booted up fine (thank god that was the first thing I tried instead of removing the CMOS battery to reset the BIOS).Looking at the reviews, perhaps what happened with my system was an isolated incident, but even so, I would steer clear of this particular unit from Thermaltake. After all this went down, I tried to find an evaluation of this unit on the LTT Labs site (Linus Tech Tip's hardware testing site), and while they hadn't tested this exact model, they had tested a similar model from Thermaltake and BOTH their test units failed during testing.Cannot recommend this item at all, would give it zero stars if I could.

Mega Loud and Stress Inducing
Took me 3 months before I realized THIS is the reason my PC sounds like it's taking flight every time I boot up a game. But worst of all, the fan speeds up randomly every 30 seconds while idol instead of staying at a consistent speed. This is a product that no-one should buy.

Recomendada al 100 No decepciona la marca para nada tenía una fuente de 500w de esta misma marca más de 4 años y sigue funcionando por esta razón me incline por esta marca de fuente de poder. Y la pregunta de si hace ruidos los ventiladores para nada es muy silenciosa
