eVGA SuperNova B3 Deceit: Did eVGA Send Reviewers Special Samples?

eVGA SuperNova 850 B3- Is this a SuperFlower or RSY PSU?

Edit: Response from eVGA provided on 10/2/2017. We’ve listed it at the end of the original news posting.

Shortly after the launch of their original GTX 10-Series cards, eVGA had issues with their 1080 cards not having proper contact with the backplate, leading to overheating, in addition to other issues due to a small batch of components they sourced being faulty. When eVGA was faced with those issues, they responded promptly, by repairing customer cards and issuing BIOS updates.  However, there is a different issue at hand entirely when a company misleads customers through reviews, as it seems eVGA may have done, in the light of mounting evidence.

In a post at Overclock.net, a member with the username “shilka” made a post detailing how the over power protection for the eVGA SuperNova B3 PSU is not working, as detailed by two Toms Hardware reviews, one of which saw a PSU give a fireworks show. As the thread continues, shilka details how review site Johnny Guru was sent a review sample eVGA SuperNova B3 PSU from manufacturer Super Flower and that unit was very well reviewed. When it came to light that Aris from Tom’s Hardware bought his power supplies from a retail outlet, things became a lot more clear. The power supplies that Tom’s Hardware bought had been outsourced to RSY  and has much worse build quality than the Super Flower Leadex-based unit received by Johnny Guru. Over power protection not working can be a major issue, no matter how you look at things, especially when you expect it to be there. When you leave manufacturing to different companies for the same product, it is prudent to do your research and ensure the products are consistent. At this point, we’re not sure if this issue was with SuperFlower providing outsourced PSU’s to eVGA, or if eVGA themselves went with a different supplier. Either way, PSU’s with decidedly worse build quality than what Johnny Guru reviewed are being shipped to customers.

I’ve reached out to eVGA for the comment, as have others, so hopefully they’ll update us on this. I think the right thing for eVGA to do here would be to upgrade any users who feels they were mislead because they bought a SuperNova B3, thinking it was based on the SuperPower Leadex platform, to a PSU more reflective of the review sample Johnny Guru received. The over power protection issue needs to be addressed, as well, so eVGA can use this opportunity to actually do some solid customer service and kill two birds with one stone.

What do you think about this situation? I know it would upset me if I reviewed something and recommended it to our readers, only to find out that a different product was being shipped out for them to purchase.


Edit: At 12:08 PM PST on Sunday, October 2, 2017, I received this response from Jacob at eVGA. This reply dodges my questions about the non-working OPP and reiterates the eVGA warranty. That’s where this stands. 


“EVGA stands behind its full line of products, and the 5-Year Warranty on each B3 power supply demonstrates the confidence EVGA has in the quality and safety of each product shipped. If anyone has questions or concerns, please contact EVGA Customer Service and we are more than happy to assist. In the rare instance that a replacement unit is necessary, EVGA will support with a free Advanced RMA on all EVGA SuperNOVA B3 Power Supplies.

In addition, the EVGA SuperNOVA B3 review samples, as well as the production, were all built at the exact same qualified facility.”

      This is the fifth time you’ve told me that about your site and I obviously am having a mental block on learning, so I will just be referring to you as “The PSU Master” from here on out. I am sorry for making that mistake.

      I’d be interested in seeing if Oklahoma Wolf’s PSU failed if he pushed past 100%, like Aris did, to see if the issue does indeed lie with shoddy manufacturing, or if his unit also fails out? I know that SuperFlower outsources PSU’s all of the time, even their own branded units, so this isn’t a shock. The obvious variance in build quality and failure of the OPP on Aris’ units stands out, though. Thanks for responding, I am very sorry for spelling your name wrong twice.

      • OPP failing isn’t a QC issue. It’s a design issue. So if Jeremy tested OPP on his unit as well, I’m 97% confident that it would have failed just as well.

        • Sean Kumar Sinha

          I agree with that, but it would be nice to see a test, since the failing OPP was my main cause for concern, aside from possible build quality variances between power supplies. Just looking at the unit Aris got and the build differences compared to Jeremy’s was interesting. Manufacturing variances, what can you do? Thanks for your reply, Jonny/PSU Master.

  • Steven Kean

    Is there anyway to check your PSU whether you got a good one or bad one?

    • Shilka

      As far as i know other then to open it up and break all warranty no there is no way to know what you got

    • Sean Kumar Sinha

      Hey Steven, there is no way of knowing, as Shilka said. There isn’t specific info on which batches are affected, etc. eVGA is also tight-lipped, only stating that these PSU’s have warranty.

  • Shilka

    As soon as i read the first tomshardware review of the 450 watt B3 back in late august i personally stopped recommending the 450/550/650 watt B3 to others

    Before that i did recommend it to some so i am somewhat annoyed that i might have recommended something i knew was good but what the end user got might have ended up being totally different

    • Sean Kumar Sinha

      A few people commenting elsewhere are missing the point, from what I see, saying that cherry picking is common and that these are budget PSU’s. The bottom line is that they have severe manufacturing flaws and RSY dropped the ball on producing the Leadex-based unit. Bad soldering and non-working OPP don’t give me any confidence in the product. Thanks for your post at OCN. I wouldn’t have picked it up, but eVGA not commenting on this issues since the Tom’s review is bothersome.

      • Shilka

        Yes i noticed that many dont seem to get that that its a problem that the OPP not working when its advertised by EVGA to have that feature

        Everyone would be angry if their video card came with less VRAM then advertised and this is the same thing

        • Sean Kumar Sinha

          Exactly. The fact a reviewer got a better quality sample than the retail channel is seeing is upsetting, but we see that happening in the industry all the damn time, so I wasn’t surprised. What was surprising is that these PSU’s had horrible soldering and build quality, along with missing a basic feature that is designed to keep you safe. I just hope this informs people with the B3 that their PSU’s might not have OPP and they can be putting themselves in a bad potential situation.

  • Xazax

    I bought one of these off Amazon.com a month ago for mining, never had an issue let alone I probably pushed passed the 850w a few times. I don’t get the big deal here.

    • Sean Kumar Sinha

      The over power protection on these PSU’s isn’t working properly and failed in two different Tom’s Hardware reviews. Of course this issue may not affect everybody. However, if you bought the PSU expecting it to be based on the SuperFlower Leadex platform and got a PSU with lesser components and non-working OVP, you’d probably be pretty upset. Over power protection not working is a HUGE potential issue.

    • David Macdonald Ajang

      Probably because you didn’t read the article properly.

      • Sean Kumar Sinha

        I can’t assume, but he DID say he pushed his SuperNova B3 past rated specification and I have to wonder if he was walking the razors edge with that one? Non-working OPP is scary. I’ve seen the issues it can cause. I product managed a couple of PSU’s in my days and it’s not easy, but you’ve gotta cover the basics.
