I don't have knowledge about power supplies. Nevertheless, it seems quite stable, I haven't had any drops or spikes in the power. The cables are quite durable and it also has the 600w for the Nvidia cards. There are plenty of ports, the problem is that the cables take up a lot of space because they are quite large and the connectors are not made at an angle, so they take up a lot of space on the components. Personally, my case had enough space to hide them so it doesn't get too messy.

It is still too early for an evaluation since it was purchased 2 weeks ago. Careful packaging with all the necessary cables and ties for easy and tidy installation. I trusted Seasonic again for the second time since my previous power supply was also Seasonic (X850 gold) bought 12 years ago with a 10-year warranty. Suddenly and without any power stress, it blew up, but nothing in the PC was damaged, as it seems its protections worked despite its age. Personally, I consider it a top company for power supplies. Time will tell...

very high-quality power supply, I upgraded after an ocz 80 silver. Long cable length, well-wrapped and its operation is quite silent. nothing goes wrong with seasonic.

I won't dwell on the obvious, excellent and high quality, but pay close attention to how many PCIe cables your graphics card needs, many now require 3 cables, this one comes with 2.

After 15 years having a corsair 850 watt, i changed into seasonic just to be sure !
Went for the 1000 watt since the gaming world is upgrading a lot.
Hope it lasts like my previous beast.
I believe it will.
Japan power at its finest.
No wonder seasonic is the best.

In general, I have nothing bad to say about power supplies from this company, and my previous one was from the same brand, just smaller. After 6 years of use, I took it out of the case as if I had just bought it new, and I put this one in its place to support my new graphics card. So far, flawless performance.

Pure disappointment. Purchased at 140€ and after almost a year it developed a problem with the fan, resulting in crazy noise. It should be noted that the computer was used quite lightly and was placed on a desk without dust. Most likely I got a defective unit, but come on Seasonic, their power supplies are supposed to be top quality.

One of the most reliable and future-proof power supplies you can buy right now, with full compatibility for the latest GPUs (RTX 40/50 series) and a native 12VHPWR cable (16-pin) without adapters.

First time getting a Seasonic power supply (I had the Corsair TX550M) and the difference in quality is noticeable. Everything comes nicely organized in little bags with all the accessories you might need (it even has Velcro cable ties). LITERALLY SILENT (and keep in mind it has a large 135mm fan), you just need to set it to hybrid mode with the button on the back. The cables are sleeved (each individual wire of each cable) and are a bit stiff (they require a bit more force to adjust and plug in the various connectors) but we're talking about a lot of durability. Beyond that, the voltages are completely stable as is the performance it delivers. Finally, it comes with a 10-year warranty.
Edit 23/10/2025: Almost a year later, it's just like it was on the first day. Silent, stable in operation, and aesthetically pleasing.

ATX 3.1: Released in 2024, it includes further improvements in power delivery and efficiency. A significant change is the introduction of the new 12V-2×6 connector, which replaces the previous 12VHPWR, offering enhanced reliability and performance.

PCIe 5.1: Released in 2022, it maintains the same bandwidth as PCIe 5.0 but introduces improvements such as built-in error correction (ECC) for increased reliability and improved energy efficiency.

Power supplies that comply with the ATX 3.1 and PCIe 5.1 standards offer improved power delivery, increased reliability, and better support for the latest and most demanding computer components, compared to the previous ATX 3.0 and PCIe 5.0 standards.

First contact with this specific company, which based on what is written, is top-notch in power supplies. At first glance, it looks sturdy and well-made. The black bags that hold the cables and power supply are very nice. It is expected not to disappoint.
