[EOL] PSU Tier List rev. 14.8

[Juular]

@AlgebruhOPP trigger point for most PSUs are about 130-140%, not 100%, it's not okay to overload the PSU at this extent. Most good PSUs still work in specs when overloaded, including RM-x, you can see all overload data in Aris reviews (ripple at 110% and voltages at just before OPP & OCP trigger points at protection tests page).

It's CWT according to the spreadsheet (CTRL+F for bq! DP P12, spreadsheet is also linked on the list for future reference)

Thanks! I did check, but I CTRL+F'd the full name, so I didn't find anything, heh. Sooo, CWT, as far as I remember, doesn't have the best track record overall, right? Or am I wrong there?

You are a little wrong. They manufacture a wide variety of PSUs, ranging from mediocre (not complete trash though) to some of the best PSUs out on the market. So really, it depends on what specific PSU you would be talking about. For the DP P12,  it's a high quality PSU looking at KitGuru's review on it, though it's still Tier A low priority since it's only a single review.

Yeah, I figured. Just like any of these manufacturers, there's a wide range. I actually just read that kitguru review right after I posted. Lots of good info there. Thanks for the help, dude!

My PSU is a few years old now and the model does not directly map to the Tier list so I am looking for some advice on where it stacks.  It's a Seasonic SSR-650RM 80+ Gold modular PSU.  I am hoping to be able to run it with a RTX 3080 since all the test systems show max TDP around 450w when not overclocking, and still under 550w with heavy OC.  I am still running a i7 6700k CPU @ 4.5ghz for now, but plan to upgrade to a Zen 3 8 core later this year.

No, I would get a new PSU and 750W Min...

 

The G is an older unit, not too bad, but still wouldn't use one today for what you are planning.

That's Seasonic G RM in tier A low priority it's there because it apparently had incompatibility problems with AMD Vega so i'd assume it wouldn't be any better with RTX3080 but you can try.

Thanks! as I checked the model name is exactly what I mentioned

I think the M-V2L has green color on the PSU right?

I bought the DQ-850M and it was absolute shite

 

Now whenever I removed my case the computer just randomly turning itself off. And sometimes I can't even power up my computer! I had to unplug the thing and replug again. Tried multiple AC cables and it's the same.

What do you mean "whenever I removed my case"? Moved? If your PC shuts off and you have to unplug and plug it back in in order to turned it back on, that would mean a protection in the PSU is detecting a problem and cutting power off to your system. The slight movement may have cause something to short out

@pote2639 Seat your mains cable all the way in.

 never happened on my old S12II though. As "remove" I mean whenever I'm removing or putting back in my case panel the computer just randomly turning itself off. Also everytime I want to boots my machine from the long shutdown I have to unplug the AC cord on the PSU side and replugging it again before it can boot. 

 

Is multi-rail psu that sensitive to the electric shorts or I was using my computer without proper grounding for the whole time lol

Cables and sockets are different, some may need more force to properly seat the cable, you can't break it, force it in flush.

Although I have hard time imagining how that might be related to AC cable not properly seated it ... Maybe you indeed have a loose or barely connected cable inside your case, reseat everything.

Okay, I'll try to reseat everything now. Will report back later, thanks for the help

Did reseated everything, still the same. I tried to plugged everything back with my old S12II and it's working flawlessly. I'll just RMA it I guess, bad luck for me.

 

EDIT: Deepcool PSU are out of stock rn so I asked for refund and go for Corsair RM850, zero problem so far. prob my first and last experience with deepcool.

SilentiumPC Supremo FM2, Sharkoon Silentstorm Cool Zero, Corsair RM, Adata Core Reactor and Enermax Revolution D.F.

Well, i'd prioritize them in exact opposite order, from Enermax to SilentiumPC.

Ahh shiz I use the ModXStream Pro 600W, rip me. Oh well, 7 years still going strong. 

[XemdeaX]

I see Seasonic S12II units here on tier D and i think thats a big mistake. 

1. The article listed as source doesn't mention the unit not having UVP

2. During the 1st mining craze me and a few of my friends all started mining on S12II Bronze, my S12II-520W unit ran at about 55C ambient at a load of 585W from the wall for at least 2 months non - stop. One of my friends had a S12II-620W and forgot to undervolt the cards resulting in a measured load of about 700W (hope i remember this correctly as its been a while since this happened) for about 1 week before he realized what just happened. -> PSUs survived!

2nd mining craze came and we all started mining again(eth this time) with the same PSUs but some bought some more FOCUS units and S12III. -> Both S12II units survived while running close to max load for months!

3. After all these years smoking in the same room with my PCs i eventually decided to open up the S12II for cleaning and found it completely brown with nicotine - took a full spray of isopropyl to clean it and guess what? I still use it on my 4th PC now (not counting the mining ones) running strong with a 3700X and a GTX 1080 Hybrid FTW (fine tuned for max OC).

 

Out of all the Seasonic units (Focus, S12II , S12III) between us we only had to RMA 1 S12III because of a faulty fan which might have been because of user error. Now before people say we got lucky let me say this: I've used and built PCs with a very wide range of PSUs. On top of my head id say at least 150 units from different brands. Seasonic were the most reliable and had the lowest failure rate - 1 bad fan and a DOA SH unit i got in bulk with other brands; in both cases could have been user error or incorrect storing of the units. With this in mind i'm really curious to know that is the basis behind your "Tier D" rating of S12II series? Did you just assume that being a budget PSU it had to be shite or what? 

 

Since i can no longer find the original jonnyguru reviews for S12II that conviced me to use SS i did find this:

https://www.hardwaresecrets.com/seasonic-s12ii-bronze-520-w-power-supply-review/8/ - TLDR: . "It passed with flying colors in our tests: efficiency between 82.4% and 86.5%, voltages closer to their nominal voltages than required...Plus we could pull up to 588 W from it with efficiency still at 81.7%."

[Juular]

@XemdeaX S12II/M12II X20W units are group regulated, they wouldn't end-up in higher tier regardless. They were put into low priority subtier because they apparently lacks UVP or it doesn't work properly/reliably, the article linked contains UVP tests for two XFX units based on this platfrom. Your experience of overpowering these PSUs doesn't have anything to do with UVP, either way, 12% overload should be okay for 2 months for non-trash level unit. Any reviews of S12II platform passing tests 'with flying color' would be obsolete because it's 10 years old unit and things changed since then, if you're still using it with GTX1080 then you're doing it wrong.

I've this VS550 PSU ( gray label ). Is this the 2017 model product or 2018?

Thank you for the explanation, i know its group regulated but since the voltages are rock solid i don't really care. As for the UVP tests on XFX units - "platform based" doesn't mean identical plus i'm not too concerned about UVP anyway. As for it being 10 years old all i have to say is this: i'll take reliability and longevity before anything else. 

I'm not prasing SS because i personally own a unit or two - i've had a lot of BQ/Corsair (not SS based) and other top tier brands fail me or my friends/customers while SS units soldiered on. 

 

At the end of the day we can agree to disagree, at least i understand the reason behind the rating.
