Wow am i seeing this right? corsair CX is now tier B+ and CXM on tier B?

Even though Corsair uses the same branding to imply that the CXM is the same as the CX but modular, there's actually a 2 year gap in their release dates. The CX is newer and more well designed.

There are Several PSU's in "Tier c" that do not "meet c6/c7 crossloads".  Whatever that's supposed to mean.  But they are still in "Tier C".  Either you aren't applying your standards consistently, or you don't understand the performance characteristics of the PSU's on the list.  

I believe he meant to say "c6/c7 sleep states".

 

Care to point out which units those are, so they can look into it? That would be helpful.

But It shouldn't come to that at all since you can change the rules.  If a rule is resulting in erroneous rankings, the solution is to fix the problem. You don't dodge responsibility by blaming "rules".  On the plus side of things, you have a bright future as a bureaucrat.  

The criteria for each tier is clearly listed out in the spoiler at the top of the first page. In the interest of remaining as objective as possible, if a unit fails or is missing out on even just one aspect of a particular tier, then it stands to reason to drop that unit down to a lower tier, and so-on. The rules are there and to the best of the knowledge of those who have been working on this list (which is not just one person, btw), they have sorted all units accordingly.

 

I like to think of this type of thread as a "community effort" to help the community as a whole. That being said, instead of just claiming "there are units in the wrong categories" and "therefore you need to fix it" without including any helpful information, why not share and help improve the list?

 

So then, which specific units don't meet the criteria of their category? Please enlighten us and contribute. It would be appreciated.

Nicee actually i just bought CX550 for my build after deciding which is better in terms of value compared to CXM550,

this makes me feel good haha.

Thank you very much for your recommended power supply list and hard work to build this list. This list save me and other people a lot of time from buying shit power supply that can potentially destroy the whole computer. In addition, this list save a lot of people time from spending more than 2 hours from researching the power supply they are about to buy and turn out it is a no no power supply.

I have nothing to do with this list.

I still use your recommended power supply list on your site.

So psu listed for high end gaming rig with single gpu setup so does this mean it is not recommended for multi gpu setups?

not per say, you can run those just fine

 

it's mostly to give people an idea for the use we'd recommend for it

Same thing as i'm aware. PSU that doesn't meet crossloads that C6\C7 enabled system puts on it when idle, likely will not claim C6\C7 sleep states support either.

i want to change this to the atx spec that introduced this (recall being 2.32 or 2.4) but i only have 2.52 on hand, so i can't really yet

 

if anyone has it though, happy to receive

Isn't that the sole reason to have tier A+ then ? To differentiate between otherwise same-quality units capable of running multi-GPU (aka having well configured multi-rail) and those that will be mediocre at most (high ripple) or not capable at all but still good for single-GPU so there's no reason to put them lower. If there's some other reasons you can't put some units that are good for multi-GPU in a tier A+ then maybe rename tier A+ to A++ and put those one tier up to new tier A+ ? That's going to be complicated but people looking for PSUs good for multi-GPU will appreciate it for sure.

Lmao the focus series went from tier a straight to not recommended. Good thing I bought the new gx 650w,

me too, 550w model hehe

well... it's more or less been a simplicity choice

 

multirail functions as a breaker in your house does, so it matters more at higher current, with my personal limit being 650w for a single rail, as it's after that likely to burn through it's cables with a voltage drop

This, to me, seems like a misunderstanding of semantics. For each tier, it is stated which situations those units are "ideal" for. Not which units you MUST use for those situations. Can you use an A or B tier unit for a multi-GPU system and still have it be reliable? For the most part, yes - but those are not "the best" choice, not the "ideal" choice for such a use case.

 

Speaking to everyone with concerns about the list:

 

I honestly don't see the confusion in this list that others are getting so caught up on. It's not like the tiers are to be taken absolutely literally. It's categorizing which are most ideal for those uses and which are of higher-quality. 

 

This list is meant as a guide or reference for someone who doesn't know what to buy or which is ideal for their situation. In that regard, I think this list serves it's purpose just fine. clearly enough. Could it use some refinement? Of course. All in due time.

 

Just seems like there's a lot of "splitting hairs" here, rather than looking at the big-picture. Hopefully that makes sense...

well... one thing... can you snip that post please?

 

second, tier b will technically do, but higher is always better

for a gaming PC, tier B is the bare minimum.

Not only that but these and up are most cheap in most regions, no reason to go lower. EVGA GD, GQ, B2, Corsair TXm, CX(m), be quiet! Pure Power 10\11, CM MWE Gold, Rosewill Capstone G, Enermax Revolution XT, Thermaltake Toughpower, it's hard to find anything cheaper than these, and if there's it's straight up trash.

I'm from Colombia , the cheapest is Corsair Cx 650

Tier D - Not recommended

Seasonic Focus (Plus) FX 2017

 

Oof.

Probably the first time I saw a high end PSU went straight to D Tier :(

I would be one of the best of Tier A if not for that damn OCP bug.

it's more of the second revision with the ripple issues that we made this choice

 

a similar thing has been done to the EVGA G3 with it's protection issues

Hi, 

Why BeQuiet Straight Power 11 better psu than seasonic prime gold/titanium?

because the prime doesn't meet requirements regarding multirail ocp, otherwise it would've been the same tier as the very least
