Question Which of these PSU should I pick?

[rbogomolec]

I went cheap on my last PSU and it died after 18 months. So I decided to go for a decent one this time. I'm limited to these here cuz my old one still had varanty and I have to pick one of these from the same store in order to get the refund.

ASUS 850W ROG-STRIX-850G, Black, Full modular, 80 PLUS Gold, ATX 3.0, 90YE00P2-B0NA00​

Be Quiet 850W Straight Power 12, Full modular, 80 PLUS Platinum, ATX 3.0, BN337​

Corsair 850W RM850X Shift, Black, Full modular (sidewise), 80 PLUS Gold, ATX 3.0, CP-9020252-EU​

Seasonic 850W VERTEX PX-850, Full modular, 80 PLUS Platinum, ATX 3.0, VERTEX-PX-850​

The last one is 60€ more expensive than the other 3, so I wouldn't prefer that one unless it's like 3x better then the rest. I don't use much juice when gaming, CPU+GPU never gets above 250-300W (CPU 30-40W max and GPU around 250W max). I also don't play sessions longer than 3h max. I'm going with a 850W PSU because of my GPU. But I don't need a beast. Just something that isn't likely to die on me. And I want it to be as quiet as possible. Loudness is one of the main factors I care about.

CPU i5 9400f
GPU RX 6800 XT 16 GB GDDR6
2 SSD
1 HDD
(I don't know what motherboard I have , some ASRock thingy)

Use the calculators.

Look inside the case (power down, unplug, open) to identify the make and model motherboard.

The first option is from ROG, and you'll be paying a significantly higher price for the brand. Both the Corsair and Seasonic options are excellent choices, but keep in mind you will also pay more for the Seasonic brand. The Corsair model is cheaper and supports ATX 3.0, as well as PCIe 5.0. It will provide more than enough power for your system. If you want to pay more for an extended warranty, the Seasonic model comes with a 12 year warranty and will work just as well with all the same features as the Corsair model. It just depends if you want the cheaper Corsair model or expensive Seasonic for a better warranty.

The first 3 units are all good with 10 year warranties.

The Seasonic 850 PX is a more efficient psu with a 12 year warranty.
They warn you to not be alarmed if the fan does not spin until there is a heavy load.

I bought mine by mistake, but am very pleased with it. I have never herd the fan.

And... to identify your motherboard, run cpu-Z

Cool, thanks man! Btw, is it important what motherboard I have? Like, are there any compatibility issues between the PSU and different motherboards?

The first 3 are all somewhere around 210€ (5€ more or less). The last one is 265€. I really don't care about the 2 years warranty extra, cuz I doubt I'll be using the same build for 10+ years. But judging by what you've said, I can't really go wrong. I'll take look at some reviews tonight at work (don't wanna waste too much of my free time on this 😆) and then I'll decide. Thanks for the help!

Any motherboard should be fine.
The height and width of an atx psu are standard. The length can vary.
If you have a small case, the length available for a psu is the one dimension to check. Not a likely problem.
