Seasonic PRIME PX-1600 - 1600W - 80+ Platinum - ATX 3.0 & PCIe 5.1 Ready - Full Modular - Premium Japanese Capacitor - 12 Year Warranty - Nvidia RTX 30/40 Super & AMD GPU Compatible (Ref. SSR-1600PD2)

Its been truly great after a few months of using it now. It lowered GPU whine on a XTX and a 4090 over my past mid end PSU. It's very quiet, never gets hot. Cables it came with were nice quality. Unbelievable efficiency, check hwid and you will be shocked by how great it converts power. Just a true winner.

High quality build and feel, came well packaged. Looks nice, works great, easy to install and fits snuggly into my case, and is powering a server motherboard with dual EPYC processors and two GPUs without a hiccup. Well worth the price.

Beast of a power supply , best warranty in the industry and best rating you can get with the titanium rated version . Built really well and looks nice also

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.

Costs a pretty penny, but this is one component that's going to travel with you from build to build.Why? 1.6kW is basically the max power you'll get out of a standard North American wall socket. And it supports 2 ATX 3.0 connectors, which are both rated at 600w - and that's 3/4 of your power budget right there - you just can't get more out that poor socket. That standard just came out and will be there for a while. GPUs will basically have to adhere to it.In 220V countries (or if you are lucky to have a socket like that in your house in the US) you could potentially get more power into a PSU, but I really doubt a mass market manufacturer is going to go for this any time soon.On top of that, it's really hard to get more efficient that this PSU already is.I've built a 2x4090 + Threadripper Pro using this puppy, and it performs admirably, given that at a max load it really pushes the max power limit of both the PSU and the wall socket. This is what you get when you use quality components!If you add all of these points together, you can see, how this is going to be an ultimate PSU for a while, I think for the next decade. It's cost? Pay once, cry once.

Power supply is big, you may want to get dimensions to see if it will fit in your case but most full towers should be fine. Very nice quality and build. Cables are easy to manage in the case. As to how it performs? It’s a power supply at the end of the day, keeps my overclocked 14900k and 4090 happy. Do i see a difference from my older evga platinum power supply? Yes actually, this atx 3.0 handles my 4090s power spikes better causing minimal circuit breaker tripping. I was experiencing more with the evga. Overall I would recommend for high power consumption components and newer systems especially nvidia high end cards.

I couldn't believe it! After building everything and troubleshooting for hours, I couldn't understand why my PC wouldn't turn on! And then it hit me. So I read the Seasonic manual, and it said to use the tester that came with it. I thought "No way, this is such an expensive item, there's no way..", and then low and behold... the tester showed that the PSU was NOT functioning as it should.Admittedly, had I read the manual and followed step 1 : "Test the PSU first before building." , I wouldn't have wasted so much time and effort. But one of the top of the line PSU's definitely needs better quality control. I was so irked by the DOA unit, I just went with another brand after..

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 pleased.Others brands I've used are Be Quiet, Corsair, and Mushkin.
