Fantastic power supply, but mine had a terrible flaw.
This is an excellent power supply, but I want to explain the problem I had with it in case you run into this. I bought this to run my PC along with a high-end video card, the AMD Radeon RX 7900XTX, which draws quite a bit of current off of 6 + 1 connectors. This power supply does have the three connectors, and they are dual ended, meaning one could do the purpose of two. Because of the high power drop, I used the three connectors separately, but for the last year I would have random issues with my video card going offline because it wasn't getting enough power.This was not a problem with the p

Best value for a 1200 watt PSU
This was one of the lowest cost but solid 1200 Watt PSU's available. Thermaltake has good reviews overall and this one seemed solidly built. The modular cables were flat and easy to use. I have a new 7900 XTX GPU and it had the 3 necessary PCIe cables to power it. Its seemed virtually silent even at full load. The fan noise was only heard when I turned off my speakers.I've only had it for a day, but Thermaltake does have a reputation of reliable components and a 10 year warranty to back it.

Extremely disappointing – failed after one week, terrible support
I bought the Thermaltake Toughpower GF A3 1200W on March 2, but I was only able to test it a week ago, once I finally had all the components for my build. Unfortunately, the power supply failed almost immediately. Since the Amazon return window had already expired, I tried contacting Thermaltake technical support.My experience with their support has been extremely frustrating. They keep asking for invoices and proof of purchase; I send them what Amazon provided, but apparently that’s not enough for them. It feels like they’re just wasting my time and avoiding responsibility.I cannot recommend

Great power supply
Great PSU. Comes with a dedicated 600w rated cable for powering your graphics card. Very quiet on the normal mode and has a dedicated queit mode that isn't needed yet for the stress I have put on it. Great value.

Phenomenal PSU
Got this for a discount on Black Friday a few years back and it has served me well. Considering the main reason I would leave a bad review for this product is due to it being faulty, and in that case there is a good chance my house would have burned down. With that in mind, my house is still intact and I am happy with my ability to slap any CPU and GPU inside of my PC with no worries regarding power ceiling. This will only be true for a few more years with the way power curves are increasing though, lol.

Smaller than my older 850w TT psu
This replaced my ThermalTake 850w power supply. I had upgraded to a rtx 3080ti from 3060ti. While the power connectors on the CPU’s are the same I wanted to make sure I have plenty of power for you at full load. And this is sorta future proof by having connects for new GPUs. Works well and quiet. And it is smaller than my old psu, which made it easier to install. And the cables are a bit longer than the old. Easier to reach the mainboard.

Not bad
It arrived with cosmetic damage, but it works very well—it has no issues.
