My experience:
Ordered 3 motherboards, 3 ram, and 3 server PSUs. Motherboards and ram were flawless. Installation was insanely easy. Literal plug and play save for a few bios modifications.
However - server PSUs have been nothing short of a nightmare. First PSU flashed a bright white on startup and didn't turn on again. Second PSU worked and I managed to mine equihash on HiveOS. But then I heard a loud SNAP, and found the PSU dead smelling of burnt plastic and hot to the touch. Tried the third PSU after, but it never even turned on. There is nothing abnormal about my house and I already had two rigs going.
Customer support has been nothing short of outstanding though and I have heard nothing but good things about Octominer. I think they just have a bad batch of Server PSUs that are either manufactured cheaply or have poor quality control. That would explain how their price is so low. Will be looking to get a refund for all of mine.
Yes, we had a problem with the server PSU. The factory that makes them for us made a big mistake, they have 2 versions. 1 version only works with 220V , the other version works both 110/220V, they mixed up some of the PSU and some % of the PSU that is supposed to be dual voltage 220/110V is actually just 220V. We are really mad about this with our PSU manufacturer and we are solving the problem at the moment. Don't worry though, it's just a fraction of the PSU and if your server PSU is running, it should keep running for a long time.
Also the PSUs have protection circuitry inside, there is no way they can damage the GPUs.
We already have professional miners using our boards and server PSUS hat have 1000+ GPU farms and they are extremely satisfied with our products.
We 100% honor our warranty and if anybody has any issues, please contact us right away on Live chat or email and we will refund your order and send you a return shipping label for the defective PSU.
Thanks to everybody who has supported us and sorry about this issue!
@octominer I have a reliable electronics manufacturer (with strong R&D) that I recommend you use. They can manufacture the motherboards and PSU for you.
