I never claimed EVGA was on a grand conspiracy scheme trying to cheat everyone and save a little bit and all that Nor did i attack EVGA or had any intentions to hurt their sales and reputation or any of that so if you understood it that way you misunderstood As for EVGA being invited to defend themselves i and many others have already reached out to EVGA and gotten no response other then that sent to legitreviews All i was trying to point out is that two store bought samples tested by the same reviewer (which also does testing for techpowerup) seem to have the exactly the same flaw in that the over power protection does not work or at least does not work on some of them Over power protection or OPP is a basic feature that has been around for a long time and you can find it on almost everything that is not junk OPP is an advertised feature listed on EVGA´s own site Go under the features page and look for youself if you dont believe me https://www.evga.com/products/product.aspx?pn=220-B3-0450-V1 https://www.evga.com/products/product.aspx?pn=220-B3-0550-V1 https://www.evga.com/products/product.aspx?pn=220-B3-0650-V1 https://www.evga.com/products/product.aspx?pn=220-B3-0750-V1 https://www.evga.com/products/product.aspx?pn=220-B3-0850-V1 If the feature is advertised it should work as advertised And as a consumer that paid for that feature you would expect it to work well it does not at least not on some of them If you bought a CPU with 8 cores and it turns out that there is a design flaw that means you can only use 6 of the cores would you be happy and keep that CPU? The answer to that would be an obvious no you would not and the same thing applies to an non working OPP or at least it should.

Found this on youtube after looking around https://www.youtube.com/watch?v=8wu3hUkPF0U That is how the B3 looked after it fried itself

Normally i dont like to copy and paste from another forum but this time i felt it was needed in case anyone here on linustechtips was not aware and bought a B3 expecting it to be better then it turns out to be Link to the OCN and the TPU threads http://www.overclock.net/t/1638984/why-you-should-not-buy-an-evga-supernova-b3 https://www.techpowerup.com/forums/threads/why-you-should-not-buy-an-evga-supernova-b3.237486/ Getting straight to the point and why you should not buy an EVGA SuperNova B3 and the reason why is it seems like the over power protection on the B3 series does not work as not one but TWO samples has failed to have its over power protection kick in and thus the PSU fried in the case of the 450 watt and in the case of the 850 watt it can no longer power on Links to reviews http://www.tomshardware.com/reviews/evga-450-b3-psu,5160.html http://www.tomshardware.com/reviews/evga-850-b3-psu,5186.html There has been no clarification or statement from EVGA or Super Flower about this issue so until there is or even IF there is you should not buy a SuperNova B3 Unless you dont care about over power protection Later post after more information came to light Well well well the plot thickens and i now have an answer for why the samples OklahomaWolf from Jonnyguru got seemed so much better then the ones Aris from Tomshardware got The answer to that question is OklahomaWolf received a press kit B3 made by Super Flower where Aris went out to a store and bought an off the shelf example and those are made by RSY which is a subcontractor So in short EVGA sent a sample to OklahomaWolf better then the ones you find in a store so thats why it passed his testing unlike Aris which got an example exactly like all the rest of us consumers would get This is about the most strange thing i have heard about in years if it really is true and is probably why EVGA has not made any statements All of this info has come from jonnyGURU on the jonnyGURU forum and from Aris on the Tomshardware review page http://www.jonnyguru.com/forums/showthread.php?t=14808 http://www.tomshardware.com/reviews/evga-450-b3-psu,5160.html http://www.tomshardware.com/reviews/evga-850-b3-psu,5186.html One thing i should clarify is the fact that the B3 is made up of two different platforms so there is a difference between the 450/550/650 and the higher 750 and 850 watts http://www.orionpsudb.com/evga The lower wattage units are of a somewhat lower quality which is why the 450 watt tested by tomshardware fried itself and the 850 watt tested by tomshardware just died

Not saying its not just saying Seasonic has super tight competition from Delta and Super Flower hell even FSP and HighPower and belive it not Enhance Electronics are not that far behind Seasonic these days if not ahead of Seasonic. If you look at the OP you can see the data for yourself if you dont belive me

Again came in fourth, and it would have been sixth if the Cooler Master V and Antec High Current Pro Platinum was compared as well Last 80 plus has nothing to do with quality at all its an efficiency rating not a way to find quality

I am fine thanks. I wish it was not such a major task to recode my thread from OCN, I tried making a copy and the pictures would not work. So had to make it text based and that kinda defeats the point

AXi came in third from the top and the RM fourth from the bottom Please read the thread dont just post what you think is best

Corsair RM came in 4th to last in the conclusion that does not mean its bad just that others where better

Normally i stick to OCN but i thought some of you here might find this interesting http://www.overclock.net/t/1482157/best-fully-modular-700-750-watts-psu#post_22109815 Other work http://www.overclock.net/t/1431929/psu-index-thread I get asked very often what is the best fully modular 700-750 watts PSU? so instead of answering that every time i am going to make another info thread well sort of. First off before i begin no i have not reviewed any of these units nor do i claim any credit for it, Its all done by Techpowerup so all credit goes to them. Since Techpowerup does not have reviews for every single 700-750 watts PSU i can only pick the ones they have reviewed which means the Cooler Master V700 is not in thread however sad that might be. Now the overall winners here is the EVGA SuperNova G2 and the Super Flower Leadex they have the best ripple suppression of them all, And they the second best voltage regulation after the AXi, And they are cheaper then all the others besides the SilverStone and the NZXT. And both G2 and Leadex its pretty much the same price as the Corsair RM. So the winner of best value also goes to the G2 and Leadex Corsair AXi is second best here its voltage regulation is better then the Leadex/G2 yes but its ripple is nowhere as good and the price its sold at is far too high Corsair AX760 and the Seasonic X are in the middle here but again the Leadex/G2 are almost always priced cheaper so not really worth it unless they are on sale The worst of them all is the is NZXT HALE 82 V2 its has the oldest and cheapest platform used the worst ripple and the second worst voltage regulation, Dont buy this one its crap Second worst is the EVGA SuperNova NEX750G it has the second worst/cheapest platform used worst voltage regulation but ripple is not actually that bad. Dont buy this one either its mediocre and way overpriced as well Third worst is the the SilverStone Strider Gold S it has third worst ripple but its voltage regulation is only fourth worst. Again not really worth buying its very small size might make up for it somewhat but still not great Fourth worst is the Corsair RM ripple is the fifth worst just ahead of the Seasonic X but voltage regulation is third worst. Again not the best thing you can buy compared to the 4 best and its priced far too high compared to what you get
