Edit: thanks all for your input, I've taken all the input and tried to find a better proces 850W PSU, but given the current discount on the 1000W be quiet! there is just nothing else beating that deal, so I've gone with that.
My current setup is an i5-12400F + RTX 3060 Ti, 2x8GB 2666 MHz, 2x 2TB 3,5" HDD, 1x 1TB NVMe, 3 case fans, 1 air cooler, 0 RGB.
All PSU calculators tell me 650W is just enough and 750W is a comfortable headroom.
Right now I have an aging Seasonic S12 II 620W PSU that causes no issues as far as powering the system goes, I've had absolutely no problems with it whatsoever in the 5 years I've had it (started on an older, much less power hungry configuration). Except one thing. I'm pushing it close to its limits and the fan is going, it's LOUD. I can't stand hearing it over the gameplay.
So I've decided to upgrade and get something that will be suitable for my inevitable cpu+gpu upgrade a few years down the road.
My choices come down to two PSUs:
- be quiet! Pure Power 12 M 1000W 80 Plus Gold ATX 3.0
- Corsair RM850x 850W 80 Plus Gold
There's a sale right now and they are priced almost the same at around 135€. The sale does not apply to an 850W variant of the Pure Power 12 M, making it and the 1000W the same price at this moment.
At first glance it looks like I should go for the 1000W be quiet, more headroom for the same price, but idk, Corsair might be more… reliable? Both have 10 year warranties. Both are overpowered for what my components require, and that's exactly the point. I want this shit to be silent even if I'm pushing it.
Is there a better choice I should consider? Also, if the price on sale isn't as attractive as you'd expect, we get crap deals all around in my country so that's that.
In my opinion, get the Corsair.
That PC will pull about 300W at full load, maybe 500W if you take transients into account so both those PSUs are valid options in terms of power, in terms of quality they’re both good, so unless you can get a very good deal on the be quiet, the Corsair is probably the best choice.
As pointed out, thanks to a sale at a given retailer, they’re both almost exactly the same price right now. 132€ for Corsair, 135€ for be quiet!
So price to wattage, be quiet! just makes more sense even if I’m not going to use all the potential. I’m aiming to run it at a smaller load for better acoustics.
On top of that, I’m trying to account for beefier components in the future, avoiding having to buy a new PSU yet again.
