Why you should not buy an EVGA B3

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/...-psu,5160.html
http://www.tomshardware.com/reviews/...-psu,5186.html
EVGA 450 B3 Autopsy youtube video (Click to show)

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 with more info (Click to show)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/...-psu,5160.html
http://www.tomshardware.com/reviews/...-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

[Update, 10/13/2017: EVGA informed us that as of today all B3 units come from Superflower, not RSY]

Was just about to PM but seems like you where faster
And yes they should be recalled and the fault should be fixed.

I eventually find the threads. Also it was good timing because I had just refreshed the OCN homepage.
Would be nice to have another unit to recommend in this watt/price range. Every so often as I need to suggest a new unit to someone, all the good units for 450W-550W jump to ~$75 making things a little difficult. Thankfully that hasn't happened the last two times.

I would consider the new Corsair CX series to be a better option
Sure the build quality is not super but at least they are no longer group regulated.

This is a quote from the tomshardware review of the 850 watt

Until we get to the bottom of failures across EVGA's B3 family (something that would almost require the company's cooperation), we do not recommend the 850 B3. While it's apparently less likely to treat you to a fireworks show (unlike the 450 B3), an 850W PSU selling for $100 that dies after OPP testing is not good. Super Flower's platform needs fine-tuning to improve its reliability (and safety). As of right now, it appears the 850 B3 wasn't tested extensively enough before it goes into mass production. After all, tuning takes time, increasing production costs, and that's not a good thing when it comes to budget-oriented PSUs.

EVGA recalled a batch of the G2 series back in the day for a flaw smaller and less serious then one found on the B3 series so what i think they should do is either make a clarification that they are doing something to repair the OPP problem

Or just recall the whole B3 series
Failing to do either could end up costing EVGA more in the long run because of all the bad PR this might result in

If you messed up really badly its better to admit it deal with it and get it over with as fast as possible
If you look at the EVGA GTX 1070 and GTX 1080 FTW cards that overheated because of insufficient cooling they fixed that problem with thermal pads and later made a much improved version in the form of the FTW2 cards

Please make some sort of clarification or statement EVGA.

I concur. EVGA, if you're reading this, then just know that we here at Overclock.net will not recommend any B3 PSU until you remedy the problem. A complete recall is the only answer because just releasing a fixed version will not be good enough for obvious reasons.

Have you actually contacted EVGA and recommended this, or are we basically hoping that EVGA is scouring these threads for information? I'm only asking because 1 of those might get results, and the other likely won't.
