Seasonic PRIME TX-1000

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.

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!

Upon opening the box, first thing that comes to mind is, “This is the walrus.” This PSU is well made and actually comes with enough ports and cables for an over the horizon install. The Seasonic web site is also well supported for those who have the slightest question about what they’re doing.

The Seasonic Prime TX-1300 is the King of the Ring! Don't waste your time or money on anything less. It will only cost you later. If higher .1% lows is a goal, START HERE! Nothing else matters without the stability the TX 1300 provides.

So far 5 star because it came as ATX 3.1 but haven’t tested it yet so don’t know performance yet.
