An Overclock.net member, "shilka", posted late last month over the failure of power protection in EVGA's SuperNova B3 power supplies, specifically the 450 and 850 W models. This adds to the concerns first raised by Tom's Hardware, one of whose review units created fireworks. Normally, for a product that has been on the market for some time, as the B3 series has, one could chalk up such incidents to a faulty batch. But it appears that might not be the case, considering JonnyGuru also reviewed EVGA's B3 and did not encounter any fire hazards.

Looks like EVGA got caught with their pants down. They are highly overrated and I have never trusted anything from them.

Naa just their cheaper units are shady. Cutting the wrong corners perhaps.

That's a good point, but when several reviews paint a completely different picture, rating X or Y part as trash and telling people to stay away, compared to one of the leading review sites for PSUs, that's like VW hiding the diesel emissions thing. It's blatantly lying to your customers... especially when the highly regarded reviewer gives it a golden rating. That can be highly dangerous, as this PSU is of generally poor quality. :/

You're claiming EVGA gave one reviewer a really good unit, and the other a really bad unit, with the chance the really bad unit would fail. Why wouldn't EVGA just give them both really good units. Surely they have more than just one "really" good unit. Do you agree?

The fact that ANY of you can draw some statistical significance from a handful of units really calls into question the collective intelligence of those involved. I know many people on here aren't well educated and barely possess a high school diploma..but..c'mon. Even 5-10 units doesn't matter. The sample is meaningless. I didn't expect anything different from the community.

This is nothing new in the PSU game. Bait and switch. I trust Seasonic, about it.

The moral of the story, don't buy sub-par power supplies. What kind of quality do you expect from $20-40 450W bronze power supply. Anyone notice the SeaSonic ad on that techpowerup article. Are we seeing who's really pushing this discussion on review sites?

Almost perfect that you mention Volkswagen.

Volkswagen took the blame for something everyone was doing, much like EVGA in this scenario.

EVGA PSU are being manufactured by several facilities, two of them are Super Flower (top end) and RSY (OEM/low end).

JonnyGuru got one from EVGA which was manufactured by Super Flower.
Tom's Hardware, TechPowerUp and "shilka" bought theirs off retail, and apparently it was made by RSY.

Three RSY ones failed and caught fire (one from Tom and two from "shilka"). JonnyGuru's did not as well are TechPowerUp's.

They claim on the one hand, that EVGA are cheaping out and make it sound like "omg your PSU is going to get on fire!!" in order to generate clicks and pull for more site views. But they also claim that this could be an isolated event, else EVGA will stop giving them things for free to review in the future, so they clam everyone down as well.

EVGA claim that they hadn't heard of any overall problems and those were only isolated cases.

EVGA is in denial. If they cared about loss leader $20-30 bronze PSUs they would've cut RSY as a supplier after the initial batch of problems.

Instead of checking they gave shilka the corporate speak : "our PSUs are built to high standards".

Ziglez, well they didn't quite put the complete information on there.

One reviewer was given a sample and was tested - unit worked fine. The other went out to a retailer and purchased one from the selves. That one was made by another manufacturer names RSY. That unit failed over power protection and instead of shutting down like it should, it kept running and practically exploded.
If you guys want all the info from the sources, visit shilka's thread here, give him some rep, and check out the links in the OP. Everything is explained properly there.

EDIT: From Tom's:

The OCP triggering points on the minor rails are set quite high, especially at 5VSB. But that's nothing compared to OPP, which is improperly configured. In our case, the PSU's primary FETs couldn't handle the load, so they blew up. What worries us most is that the main fuse didn't blow as well, so every time you connect the damaged PSU to the mains network, fireworks ensue. That obviously shouldn't happen. Once something breaks on the primary side, the fuse has to blow so current doesn't pass through. As this PSU sits, it's a potential fire hazard.

Now i understand, the article made it sound like one got a bad PSU and the other got a good PSU, wasn't very clear, Thanks for clearing it up.

Being completely fair, it's actually not clickbait when you're given a cherry-picked, higher-than-normal-quality model built by THE top PSU manufacturer... versus when you buy that same PSU from a store and find out all of that model are actually built from a different company and are all of crap design.

If three of three store-bought units died upon use (stress testing these units at that, which they should handle no problem), that's completely within reason to warn everyone NOT to buy those units. If I'm seen as "being a hater" from agreeing with EVGA lying about their product then there's nothing I can do about that. It's the truth. It's the same as Intel paying DELL additional rebates on their CPUs in the order of a BILLION dollars per year, as long as they don't use anything from AMD. Like Intel, EVGA might be a well known, highly rated company, but their known reputation doesn't automatically fix a lie that could cost people their products.
