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

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 p
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 bac
Not the first PSU I've ever purchased but definitely the best. Was heavily considering the Noctua edition to this one due to its lower decibel output. But it's not done with magic and the trade-off is increased heat across critical PSU components.Still haven't put the PSU shroud back on my PC yet and the side panel is also still off, but cannot hear anything coming from the PSU. I'm not saying it is dead silent, I'm saying I can't hear it above any of my PMW case fans even without the shroud and side panel. And I'm using high end fans that are quiet.Stable, solid, quiet performance. Extremely
The power supply itself is an excellent offering from Seasonic with great ripple suppression and top notch management of transient spikes, but unfortunately I had to buy from another retailer as Amazon shipped me a PSU that was clearly in a used condition, missing the power cord. Might have been a prior return. Amazon customer support was, predictably, all outsourced from third world countries.I'll think twice about buying from Amazon again until they start hiring Americans.
Ok I bought this to replace a evga 1000w supernova psu due to hitting 987w from the wall with this bad boy it lowered it to 757 watts so I'm saving electricity oh and the cable melting shouldn'tbe a issue with this one unlike corsair...
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 1400KFGPU- 4080 SUPER MSI VENTUS 3X OC 16GBRAM- 96GB DOMINATER 6600MHZ 32CL MEMORYMOBO- ASROCK Z790-CI have to come back and wr
Anyone with a high end 4090/5090 build with a high-end CPU, water cooling, fans, RGB, even multiple GPUs should look into either this or the 1300w. I only went with this because it offered 2 ports for the 12vhwpr direct cable and don't know if GPUs will have multiple of those on the high end in the next few generations. I always get Seasonic Prime PSUs and this is just as good as the others before.
