  1. again would you explain why 60 A ? the same thing would happen ( but needs more time) when you introduce a sustained 30-35A to most pcie cable with 12v OCP set at 40A , same thing would happen when you overload the single 12V pin in peripheral ports in the back of the PSU over 8A , it's just a matter of time to generate enough energy to melt the wire or the pins j = I ² x R x T , all you need is more time . or do you suspect that 10ms transients alone above 60A would be sufficient in causing a pcie cable to melt ? because they won't when circuit breakers are maintained and implemented properly in our houses it would never cause the wires to fail catastrophically under any overload scenario they also allow for transients , but sadly the way 12V OCP is currently implemented in PSU's doesn't do the same so we cant fully make the analogy of not having Multirail 12V OCP is like not having CB in our houses I am for the importance of Multirail 12v OCP , but not for the reasons you stated above. as a side note I applaud your efforts and IQ for making this algorithm of ranking PSU's , and I think someday you will surpass all of current reviewers @GoldenLag thank you are correct there didn't read OW review carefully
  2. He doesn’t test for opp but he tests efficiency till 870w you can see it in the results and doesn’t report shutdowns
  3. The methodology for testing shut in power with increased load per step is different than measuring efficiency, I don’t fault the equipment , I suspect he measures incorrectly you can see also what I mean by load per step here , and also see how OW got 115% with the 750w variant with no shutdowns back in July 2017 before the new version was ever released , the fix was supposed to be released in Jan 2018 btw after both Aris and zardon reviews https://www.jonnyguru.com/blog/2017/07/10/seasonic-focus-plus-750-gold-750w-power-supply/3/
  4. @Juular In short , trust only credible reviewers not select , and there is no decent psu that isn’t reviewed by Aris btw, he has the biggest database of psu reviews , and I didn’t say disregard multirail , I said with how it’s currently implemented and the actual benefit it gives us , then it shouldn’t be a demand for top tier , That makes the tier rate a BitFenix formula higher than prime titanium because that is just ridiculous
  5. @GoldenLag no one tested opp for the prefix version of the Seasonic focus plus , do you have a review of that , all we knew about it is that it had shutdown problems with high end graphics cards strangely enough when Seasonic issued a statement a while back on its Chinese website it said these shutdowns where due to aggressive OCP , which is odd as normally single rails don’t have 12v ocp , and the new version doesn’t as well , even the prime doesn’t have 12v ocp except for the 1000w variant @Juular these are not my exact two points , Specially when it comes to multi rail
  6. Nope multiple reviews with the riotoro g2 have stated that it has opp much above that value , you can see the German one I linked and look for others , also both Aris and zardon reviews are within the same time you are just speculating that it was the one based on the Previous version of the fx
  7. @GoldenLag the short answer would be , it's not cheap nor is it easy to have a state of the art lab , with equipment that are calibrated properly and periodically, and have the competence to know how to perform measurements and the importance of a consistent methodology when doing reviews to have proper judgments the only one i see who fits this profile and is currently active now is Aris , he is an electrical engineer with a PHD and decades of industry experience , he is even the only one who properly tests protections. the examples for not trusting other reviewers are endless , i have seen contradicting results over the years with many reviewers that are well known , the latest i have seen was from zardon who stated that the Riotoro enigma g2 shutdown at 107% overload ,also when he tested the focus plus he reported the same ( This shows you he has a consistent flaw when taking measurements when testing for shut in load) , now that is a reviewer who has a pretty expensive lab and decent experience , but not expertise in PSU testing https://www.kitguru.net/components/power-supplies/zardon/riotoro-enigma-850w-g2-power-supply-review/5/ https://www.kitguru.net/components/power-supplies/zardon/seasonic-focus-plus-gold-fx-850w-psu-review/5/ this is a pretty low value , and inconsistent with how OPP is normally set above 125% by almost all manufacturers to allow for transient spikes when operating within its nominal capacity , and also inconsistent with the real values of the seasonic fx ( all models) that has its opp at 137% , as Aris has stated and many other foreign reviewers have stated as well https://www.tomshardware.com/reviews/seasonic-focus-plus-gold-850-psu,5247-6.html BTW , you have decided to set the ritoro g2 in tier A based on Zardon faulty OPP measurements , as you have thought that it had its OPP is set below 120% Which you believe is when these 268mv dangerous ripples happen according to the results of another review from PCeva that no one has ever reproduced well then it neither has its OPP at 107% and guess what , another random reviewer says that it worked till 140% and then died , What to do now ? are we going to chase random reviewers to the rest of our lives ? or maybe make a tier list of PSU reviewers ? https://www.hardwareluxx.de/index.php/artikel/hardware/netzteile/46223-riotoro-enigma-g2-850w-im-test.html?start=1
  8. @GoldenLag. This my problem with how multirail 12v ocp is currently implemented and why it shouldn’t be that much of a priority to make a psu tier A+ As for the data sources ,I wouldn’t trust any reviewer except Aris as he is the only reviewer i have seen who is currently active and has the competence to know what he is talking about , proper calibrated lab equipment , consistent testing methodology and most importantly he tests protections.
  9. my biggest problem with the tier list isn't its algorithm of ranking , i have my differences though regarding giving priority to 12v ocp with its current method of implementation as stated previously the biggest flaw in my opinion has more to do with the quality of the data that you base your judgments upon ,I see judgments made based on data from reviews regardless of the competence and reputation of the reviewer and his lab equipment and does he even calibrate these equipment You can be the best Cardiologist in the world , and following the clinical practice guidelines of the American college of cardiology , but without having proper calibrated equipment all your hemodynamic parameters ( Blood pressure , Heart rate , ...etc) and blood analysis ( cardiac enzymes , electrolytes , ...etc) would be inaccurate and cause you to misdiagnose your patient
  10. As said above you need to rma to EVGA directly the reason you see lights on your motherboard when the pc is switched off is because the 5vsb is responsible for providing power to your pc when it’s off , it’s DC conversion separate from the rest of the 12v 5v and 3v rails that your PC needs when it’s powered on and therefore it’s not odd to see psu that fails to turn on although it has a working 5V sb
  11. when you hear a thunder , the first thing that goes through your mind is that it may rain or that you may get struck by lightning ? out of spec ripple at normal operating conditions is far more dangerous than absence multirail 12v OCP Multirail 12v OCP is good to have but the way it's currently implemented protects against a specific very low probability scenario of pinched wires or broken connectors that may form a resistive load , add to that you will only encounter it during the first time you start that psu that had faulty connectors or wirings or finishing a new build and you pinched one of the cables in the side panel for example ( that's another conditional probability that will make the total probability of the scenario much lower )
  12. @LukeSavenije why 60A per 12v rail ? How did you come up with that value ? There is no one that tests ovp or uvp during reviews not even Aris , for this reason
  13. As far as I know for the rmi 850 Each pcie\eps cable connector on the back of the psu has a 12vocp of 40A which supplies every 2x8pin pcie connectors , and the 24 pin and the peripherals have a shared 12v ocp @40A.
  14. Some of these are raised by technical departments and if they are feasible the get the green light to implement them , for now what I am trying to say is that we should trust expert opinions when they say a prime platinum or AX is better than X unit that has multi rail . Because he knows what he is talking about
