psu question about the psu tier list

[wassil]

hey guys iam about to build my first pc and i have a question about choosing a psu from the tier list, 

should i buy the specific model that is linked in the list or as long it is on the same series 

 

what i mean lets say ill buy a cooler master mwe, on the list it is on Tier B+ they linked a Cooler Master MWE Gold 550 W 80+ Gold Certified should i buy this exacte linked psu or can i get the same but in silver or bronze as long it is a cooler master MWE

The MWE Gold is a Tier B+ unit, the other MWE units (80+ Bronze and 80+ White) are lower tiers (just search for 'MWE' on the tier list page and you should fine four results).

So you could for example get an MWE Gold in 550W, 650W, etc. and it's all Tier B+, but the other MWE models are different.

Screw the tier list,theory and practice are 2 different things,you can like me buy the chepest PSU in lower segment which works for 10 years...and regardless you can buy AXi series or EVGA P3 which will fail in 7 day...the thing is useless,I don't even want to look at it...

getting right PSU is a matter of luck...it can fail in a month or in 10 years no matter which brand...

I have old computer from 2002 I don't even know what PSU it has and that PC still works okay,so the tierlist for me is useless.

The list is not all too good ether, there are a lot of grate PSUs ether missing or in the wrong tier. 

And as you stated a good PSU can go boom on day 1. EVGA units were know to do that for a wile.

That being sad there are better/worse PSU's and I would not just go buying the cheapest one

[Ben17]

just to add don't get the cheapest power supply you can get though btw as they are more likely to kill your hardware

it's all about probability. the higher in the list, the least chance it will fail. just because you were lucky with your psu, doesn't mean it's recommended. it's like recommending people not to wear seat belts while driving because you haven't died yet.

yes iam 100% with you, they got me brainwashed with this tier list everytime i ask about what should i buy, thnks for your honest answer

[Guest]

The tier list is "suggestive", but it does base positions on some factual data like PSU topology, fan type, etc.

 

But I tend to ignore it because it doesn't take into account all parameters and certainly doesn't take into account PSUs that are a better value in one region versus another (i.e. if you're in Germany, beQuiet is a great value.  If you're in Poland, Silentium is a great value, etc.)

 

These are the cheapest PSUs from each of the "big brands" that I would ever suggest:

 

Corsair: The CX Series (non "M"):  LLC w/ DC to DC and rifle bearing fan.  "Bronze" efficiency.  Non-modular.  Black cables.
Thermaltake: Only products that have "Toughpower" in the name.  They're LLC with DC to DC.  Modular. They have black cables.
Cooler Master: MWE V2 (not the "non V2"):  The V2 has LLC with DC to DC.  Both the "White" and "Bronze" versions of the V2 use the same LLC and DC to DC topology.  Either have rifle bearing fans.   They are non-Modular.  It has black wires.
Antec: EAG PRO (I know they're not "budget", but everything below that line is garbage).  LLC with DC to DC.  Rifle bearing fan.  "Gold" efficiency.  Semi-modular.  The new version has all black wires. Don't get stuck with the old version.

 

These are my "it will do" suggestions.  They all have double forward topologies.  I wouldn't use any of the below, but if you're on a really tight budget, they are options.  Keep in mind, if you use a high end graphics card like an Nvidia 20 series (Turing) or AMD Vega or 5000 series, the main transformer is going to squeal like a pig.  All of the below suggestions DO have DC to DC for the +3.3V and +5V (i.e.:  They are not group regulated).

 

Corsair:  CX-M.  Not to be confused with the non-M above.  This one is not LLC.  But it does have DC to DC like it's cousin.  "Bronze" efficiency.  Semi-modular.  Black cables.

Corsair:  CV650:  Only the 650W has DC to DC.   The 450W and 550W do not.  "Bronze" efficiency.  Non-modular.  Black cables.

beQuiet: System Power U9 is "ok". I'm actually not a fan of the active clamp platform the Pure Power and Power Zone uses.   U9 has "Bronze" efficiency.  Rifle bearing fan.  Non-modular.  Black cables. 
EVGA: The BQ Series.  "Bronze" efficiency.  Rifle bearing fan.  Semi-modular.  All black cables.
SilverStone: Essential series.  An oldie, but a goody.  "Bronze" efficiency.  Sleeve bearing fan makes this my lowest recommendation as sleeve fans wear out quickly.  Semi-modular.  Black cables.

 

On the opposite side of the spectrum, you pay more for a PSU and you get features like full modularity, better efficiency (Gold, Platinum, Titanium), which also means the PSU runs cooler, a better fan (like an FDB fan), and in some cases the ability to monitor PSU voltages, temperatures, etc.  Some have quieter fans than others too (zero-RPM fan mode or a better fan motor that makes less "buzzing" noise).

 

Hope this helps!

tierlist doesnt consider DOA hardware, as that isnt evaluating the PSU itself. 

 

what it looks for a criterias like protections, topology and offcourse following spec. 

 

so to say its useless because DOA hardware exists is kinda silly. 

 

 

edit: something working =//= the hardware having a good time. plenty of powersupplies that can affect the lifespan of the hardware you are using, or not shut down in scenarios where the PSU can fail catastrophically, or it is damaging the components its powering.

im sure they would love if you could suggest units that you find missing. 

 

or point out units that you see do not fit the tier. the team working on it isnt big, and there are bound to be units that will be missed.

wouldnt discount it just because there exists DOA hardware. as there is a lot to consider when it comes to powersupplies, and the Tierlist does simplify the selection process.

as fun as this sounds, especially now this would be impossible to keep up with for us. unless you'd know a way to filter out the perfect PSU for every region, you're better off grading off pure quality

out of curiosity, has there been any testing of this yet? I can believe it with 5700/5700xt, but 5500xt/5600xt sounds unlikely to me

so for people that haven't had their logisys exploding in their face the last 4 years make it a great PSU, and doesn't account for the people that did have it explode because the protection didn't trigger? and because one person had a DOA AX1600i, that makes the unit the worst thing ever? that's how this sounds to me

 

it's not a guarantee, it's a propability as far as we can theorize it

EVGA units were know to do that for a wile.

only G3 (850/1000w on tomshardware) and early batch B3 have shown to do this, the others have failed specifications in other ways or simply lack protections that I'd say are important (for example OTP/UVP on their W1 and N1 lines). EVGA sells many different PSUs produced by FSP, Superflower, RSY, Seasonic, HEC amonst others, not every EVGA is equal.

 

the list is a running project, if there are errors/complaints or anything you'd like to suggest, me and the rest of the team will do our best to improve it, but not everything is possible.

 

and after all, a project like this is after all a baseline. Do your own research around some things. all we're trying to do is to give you an idea of how good a PSU is by a methodology we're trying to be transparant about and improve over time. We have many things planned for next revision already to issue some misplacements, as well as the usual complaint of a "lack of certain reviewers". this is as of the time of writing the pending changelog, as found in the sheet

A simple google will show EVGA PSU's have a host of problems, from failing early on to giving reviews a better PSU then what is sold at the retail level. Wile some are good, I myself would not trust any EVGA PSU without first opening it up and making sure the one I got is good. EVGA should just stick to selling GPU's IMO.

Eco Zen is a bit of an unknown for me.  Andyson can be hit or miss.  Is there a review?

We all would have more information about all those models failure rates in % then useless PSU tier list.

My Fortron Raider would probably sort the guy who made the tier list into low end segment,and yet it works still after 8 years.

Don't want to mention old PSUs with maybe 350-400W back in year 2000 I think Chiftec was manufacturing those ones,when probably a lot of people didn't even see PSU from 1998-2000 year.

If I want to buy PSU,what I do is check how people are satisfied with it over amazon and newegg and then I choose and buy.

you have like Seasonic PSU Focus and Prime which is grand brand and I know a lot of people had issues with it here in Europe so not selling any more.

And you have like EVGA G2 which is mediocre PSU and my supplier sold 1000 of them without any issues,specially 850 G2 model.

Guy just lost his time making useless PSU tier list.

Fail rates are not what make or break a PSU. I don't know where you got the idea that the tier list is for which model will fail sooner lol. Time to failure is not what anybody should be basing PSU choices off because it's god damn luck.

since when was the G2 a mediocre PSU?

 

last time i checked its a pretty good singlerail, which happens to also be reflected in the tierlist.

that's why EVGA PSUs get through many tests and have succeeded. of course there are DOA and early deaths, but EVGA has been nothing that special in it, and again, not every EVGA is equal and they actually have shown to be able to fix things with for example G5 1000w

Unrelated to this, but every time I imply dislike or talk about my irritation with the tier list, someone inevitably jumps down my throat with the force of a thousand John Cenas.

 

Obviously not everyone associated with this project is that thin skinned, but if you guys don't calm down and (as a group) dial it back a bit there's going to be a point where nobody takes it seriously

Power consumption ≠ transient spikes.

 

Unless they measure power consumption with an oscilloscope, their findings are useless.

Perfectly fine to dislike the list for what it is. 

 

As its fair to say that a simple tierlist cant describe PSUs. Edit: in a way that a review can.

 

Tho to say its bad due to the existance of DOA units is kinda silly. 

 

To say it cant put fourth exeptional singlerail units is a fair critisism. And if people do have such valid critisisms, then the people can see if they can improve on the feedback. 

 

And yeah, the people commenting on critisism can be a bit overwhealming

 

Edit: tho the list atm is likely in its best iteration at this point

So here's the juicy part:

Firing up FurMark reveals dips and spikes over the two auxiliary power connectors that weren’t an issue in Metro. When we drill down into the data, current draw over eight-pin connector is taking >1A dips for one sample and sometimes popping back up in the next 2ms sampling window. The six-pin connector does this to a lesser extent, while the PCIe slot’s +12V rail encounters periodic dips (but no spikes). Cumulatively, we end up with an overall line chart that appears more dramatic. Peak power consumption, however, only gets up to about 202W.

So the spikes are there... they're just not that big.

 

Won't cause the PSU to shut down, but might make the transformer sing.

 

Remember:  It's not too much wattage that creates the noise.  It's the spike itself.  So even if the spike was from 2W to 100W within a 2ms window, that could cause the same issue.
