I looked/searched through this post pretty well, so sorry if this has been answered, but why are the Seasonic Prime Ultras above 650w not in the A+/S tier anymore? Is there something we have learned about them that has dropped their score?

It lacks multi rail OCP.

[Lmao No]

What about any 700/750/850W model in the ultra high end tier? Are they good too?

All you both need to do is read the 4th line in the top of this thread:

List is subject to change at any time, due to change in sources available.

Single rail units exceeding 650W will not be placed above Tier A.

 

That means that if a unit DID make it to Tier A+ and it's higher than 650W then it HAS multiple Rails and therefore is deemed worthy to be there (by the list makers).

What's a rail

Not suitable for anything that actually needs 700W of power.

thank you,

i will pair it with ryzen 2600 and rx 570 , so i am not worried about power delivery as long as it is higher then 500W , i am more worried about whether it will explode/damage other components or not

[atxcyclist]

Never would I have expected that a power supply with a 12 year warranty (EVGA G3) would be considered third tier. So if you buy a 750w PSU and put a 900w load on it because you're dumb, that's considered a failure of the PSU and not user error? I guess testing something in a furnace will destroy it also, so hopefully you don't use your computer on the sun.

Yeah.... no. It's group regulated and looks like poor performance.

It's a standard feature. Plus, in the case of some part failure the part may draw more than it should.

 

If every other unit has it, I'd expect it from every PSU.

Well, here's hoping my 750w G3 doesn't go out in such a fashion. With only 430~ish watts worth of load at least it's living a fairly easy life.

It likely won't. It's just in case of some emergency that probably won't happen, it'll explode instead of properly shutting down like every single other unit.

 

This is my stance: If you have it, stick with it. If you're looking to buy one, don't. There are (although shorter warranty) similar performance units at the same price point with actually working protections.

DC-DC. 

Did you look at internals of the wrong PSU, or just assume it's group regulated without checking? ?

Dingdingding!

 

Was assuming we were talking about a shit-tier PSU here.

Thanks for that link. I was wondering this exact thing, because the last time I really did hard research on rails must have been pre-2006 days when multiple rails were often seen as a very bad thing vs a single powerful rail.

 

Now I have to wonder why such an awesome series like the Seasonic Prime Ultra Titanium line has only a single rail instead of multi-rail OCP. It was my forever power supply, and still will be for a very long time probably, but why Seasonic 

[LukeSavenije]

but why Seasonic

because seasonic is about as allergic to multirail as asus and doublers

 

but on a more serious note, i currently have something along these lines asked at their r&d, so whenever i have answer on that i know more...

[LukeSavenije]

well.... i already sent these in a status, but i wondered you guys would like it as well

 

say hello to the new asus strix psu (seasonic focus)

 

[pulkmees]

Seasonic Prime Snowsilent - does that have the same problem as the Focus series or is it in A tier for a different reason ?

650W unit that is.

and just so I've said it, rather a good fan than a cheap fan and 0 rpm mode

I saw you post this on a different thread:

 

rather a good fan than semi passive mode, because with semi-passive this happens (750w seasonic focus for reference, look at the rpm/fan noise graph)

https://www.tomshardware.com/reviews/seasonic-ssr-750fx-focus-plus-750-gold-psu,5206-5.html

 

i can recommend the following

pure power 11

formula gold

whisper m

rmx

txm (though louder than the above)

straight power 11

 

The Corsair RMX 550 and 650w are both $87.99 USD on Amazon right now. Thanks for the selection of quietish psu's I'll make a choice next paycheck.

I wasn't aware of any SnowSilent unit below 750W. This will be changed soon.

no problem, and if any other psu comes into your sight, just let me know

[hello_there_123]

will the Corsair RM 2019 never be moved to tier A?

For any wattage above 650W it already is in Tier A.  What's the hang-up?

550w and below are in A+, when Jonnyguru has already said the RM is worse than the TXm in build quality. Discord didn't work so I have to post here now..

[hollyh88]

so as far as i can see.. any focus plus bought after 2018 havent seen issues? i just bought an focus plus 850 watt psu. and as for the 850 watt why so much.. well ehh the 750 was more expansive. so i said fuck it and bought a 850 watt

i will use nvidia cards so thankfully i have no issues with wattages spiking like a crazy thing
