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.

Excellent build quality, packaged cables are high quality. Hybrid mode works very well. The TX1600 is an ultra high end PSU. After a year with this PSU I am convinced it is unbeatable. Power is steady and clean. It’s quiet in without hybrid mode and with it, damn near silent. It’s hard to call anything future proof but I am confident this is going to be my PSU for years to come.

I ordered four TX-1600 (1600 watt, 80+ Titanium) Seasonic PSUs for my lab's GPU servers. All machines were running stably and continuously for days at a time. We had to power down the all servers for building electrical maintenance. After power was restored, one server did not boot, and the problem was quickly isolated to the Seasonic PSU. I then searched and quickly found the Seasonic RMA website. The instructions were very clear and there the information + photo upload was painless. Using this info, Seasonic appoved the RMA in only one day. I then packed the PSU and send it with tracking back to Seasonic (note that this is done at your own expense and is not refundable). Seasonic allowed me to upload the tracking number to a unique RMA website just for the bad PSU. After they received the bad, they evaluated and decided to replace it within 2 days, then immediately sent it out with a new tracking number. I got the replacement PSU, which is working perfectly. Overall, the process took ~2 weeks. I used the cheapest possible freight, so if I was in a rush, I could have used overnight shipping and shortened the RMA to ~ 1 week. This was by far the easiest RMA experience I ever had. Given the confidence Seasonic has in their products and their quick replacement for the rare faulty PSUs, it's a no-brainer that I'll prioritize Seasonic PSUs for future builds.

Easy to install, extremely handsome and sleek appearance, 1600W is legit, 5090 runs no problem. The power supply fit is massive however, if you’re not building in a case with lots of space, please check compatibility before purchasing. Comes with standard cables, as well as a complimentary motherboard extender for cable management. Also comes with a bunch of zip ties and other fun stuff. There is 0 coil whine, and it is extremely quiet, I hear my case fans over the psu which is amazing because I upgraded from an MSI psu which had crazy annoying coil whine. The only downside to this psu is the size, as well as the cable appearance, the cables are a little bit on the messier side out of the box and need organizing for it to look good. Nothing is wrong with the cables, and they are mega easy to install, so if you don’t care about the look then plugging everything in off the bat is fine as well. However if you’re buying this premium of a psu, you probably already have a nice case prepared as well as an eye for aesthetics. In comparison to even higher end psus such as ASUS Thor and Loki, it lacks a screen. But honestly the screen isn’t really worth the extra $200, as in my case the psu is covered fully anyway so it doesn’t really matter. Use this psu for clean builds that require heavy lifting. 10/10 love Seasonic

It's a power supply that has no power, wow, 0 stars. DOA wouldn't power on. Connected the tester and confirmed red light/no power. Reconnected my current power supply and PC turns on. For this price I'm utterly shocked. Better Quality control seasonic! How disappointing.

First off I got to say this power supply is quiet, I don't ever hear it. The quality is spectacular, I was on the fence about if I was going to get this but 100% get it stop thinking about it GET IT! Its got a 12 year warranty, and the customer support is spectacular even on the weekends You'll have someone message you back immediately. That means a lot. I'd give more than 5 stars if I could. Its kind of big so make sure that your case as the room!!!!! PC SPECS: CPU- I9 1400KF GPU- 4080 SUPER MSI VENTUS 3X OC 16GB RAM- 96GB DOMINATER 6600MHZ 32CL MEMORY MOBO- ASROCK Z790-C I have to come back and write this review and as after months of us the power supply is good as expected, and well worth the money and would be worth buying again.
