be quiet ! PSU with 4 12v rails

I am just starting to get my parts together for a Ryzen 3xxx build on a x570 mobo.
I have just bought a be quiet Silent Base 801 case and was going to get a be quiet! Straight Power 11 650W PSU ( it would have meant combined shipping and significant cost saving ) but I balked when I read about it having 4 12v rails .
I have been out of the loop for a bit ( i am retired and 60+ yo ) , but this just did not sound like a normal PSU configuration .
Is it a new standard ? am I missing something ? or should I just be looking for a different psu .

Its called multi rail and its been around for a very long time so its not strange or unheard of and one of Be Quiet main selling points is all their units are multi rail

With that being said Be Quiet are overpriced outside of Germany so there are better options in the same price range some of them are cheaper

Is there any disadvantage with multi rail power supplies ? especially with higher end ( 1080 ti ) graphics .
be quiet is actually one of the better priced brands in Australia , corsair is a little cheaper , Coolermaster and Thermaltake are a lot cheaper ( but I prefer to avoid them ) seasonic is the dearest and Fortron (fsp) seems to have dissipated from retail .
I was largely using Seasonics for the last 10 years on my own systems , but the pricing structure has changed ( of all PC parts in Australia )
I had heard of dual 12v rails but that was the first with 4 12v rails that I had bothered researching
edit just finished reading the link you posted - it seems like there will not be any major issues , with the be quiet! unit .

There are advantages and drawsbacks to both single and multi rail and some like multi others like single
Multi rail is a lot safer because if something happens to one of the rails nothing happens to the rest of the system so its an extra safety

On the other hand OCP or overcurrent protection is lower because of the low rating of the rail so if you put too much load on one of the rails the PSU will shut off and this is easy to do if you are an OC nut

It really depends on what you are doing and someone like me who just uses his PC for media use and some light gaming once in a while would never have a problem with a multi rail unit

As for Cooler Master and Thermaltake they have a ton of crap so for the most part dont buy a unit from them FSP has some good stuff mixed in with some not so good stuff and Corsair is just overpriced in most parts of the world

Seasonic is bit weird because some of their older units where branded marketed and sold as single rail units when they where in fact multi rail the Seasonic X was a case in point but i dont know what they have been doing after that so they might be single rail or they might be multi rail who knows

Some Corsair units have a switch on the back where you can switch beteween single and multi rail as you like but i dont think thats actual hardware multi rail

Like you I am not hammering the system , most of the time , I do a lot of Photo editing , some video editing , a fair bit gaming ( I am retired) all on a 100hz 1440 ultrawide .
netflix and Stan and the like I have a purpose built machine ( R5 APU ) on 1080p 32 inch samsung .
The machine that is being replaced has a Seasonic S12 from several years ago - still to my knowledge working fine . but this is an entire groung up build all new ( other than the GPU ) so not wanting to re use an older psu . ( being my personal rig and all )
If I find a PSU I think is better than the be quiet! one I will check on here first

The S12II is group regulated so please dont re-use that its not horrible but anything using group regulation in this day and age is like something from the stone age

Yes the Pure Power 11 is cheaper because its budget series and its worse in every way compare to the Straight Power 11
You also get a 3 year warranty with a Pure Power 11 compared to 5 years with a Straight Power 11

Most other brands offer 7, 10 and even 12 years of warranty so Be Quiet has some of the shortest warranty around
If you still want a Be Quiet PSU you should be looking at the Dark Power Pro 11

The best option on that list is the Corsair RMx its one of the best on the list and its $165 which is $4 less than the Straight Power and the RMx is much better
There is also the Corsair SFX 600 if you dont want to pay for the freight and last there is also the CX650 if you can live with a meh unit

Everything else is either mediocre, overpriced or junk, FYI the SilverStone Strider Titanium is is by far the worst one on the list
