Review: Perfect power supply, very reliable. Clean output - Have this in a very overclocked 14900k build with dual 4090 gpu, water cooling and 9 fans and can take it all. DC Power looks very stable coming out of it on my fluke tester. Lots and lots of connectors and flavors of plug. Dual 12vHPWR would be nice though thats not a normal build. It is expensive though worth the money.
Review: Seasonic takes care of you! - Excellent! Well worth the investment if you can afford it. The most important component of a pc. Everything else in your system relies on it, so why not protect them the best you can. The warranty is VERY long, so it could be used on multiple pc builds before you need to upgrade (as long they don't keep changing the GPU power cables. Figure it out NVIDIA!). Seasonic really takes care of you with this PSU. The TX-1300 comes with all the current cables that you will need (including a 12v 2x6). And it comes with a nice PSU tester! I HIGHLY suggest using the tester first, before you get into hooking up any cables to the motherboard. You can even test the PSU without a motherboard. It could save yourself alot time trouble shooting. One GREAT bonus feature of the tester is that it is also a 90 degree adapter for the 24 pin cable. You can leave the tester on and use it permanently (I emailed Seasonic support to confirm). Helps with esthetics and better air flow. Another feature is that it has auto fan mode if you want it quiet. I have not heard it once yet while gaming, so I leave it in standard mode. -VERY SMALL cons: It comes with clear wire combs that I found to difficult to get on to the individual wires. They were very tight, so the wires are difficult to put in. I had to had to stretch them with my teeth (I am not proud about this or recommend). I am still deciding if I like the clear plastic of the combs also. I think I prefer black or white better. The TX-1300 is long. Make sure you have room in the case. I have the FLUX PRO, which has an option of installing a PSU sideways for better cable access. I was not able to use this feature of the case, due to the PSU length. No big deal. All and all, this is a excellent PSU. If you want high quality 1300 watts, this is the one to get! No doubt!

### ⭐⭐⭐⭐⭐ Dead silent and ridiculously overengineered
*by B***F on January 22, 2024*

Only superlatives comes to the mind with this massive power supply. From the box, all the cables, the casing, accessories, everything screams 'high quality'. Very heavy, the PCB connectors are extremely well made, all the cables are top notch quality and seats with a pleasant click noise. Talking about noise, once you turn on your computer, you quickly realize how dead silent its this power supply. While running 3dmark fire strike extreme with my RTX4090 drawing 500 watts (plus an i9 13900k, 64gb DDR5 and a ton of RGB) the power supply doesn't even sweat. The plan its to add a second 4090 to practice with AI, that's why I decided to shell $600 on the best power supply available to have plenty of juice for both GPUs. Be aware this power supply is big, so you will need a big space inside your case. . In short, this thing is amazing, super high quality cables, ultra silent and absolute performance. If you have the $600, pull the trigger, you wont be disappointed.
