hmm which new psu are you talking about?? the miners with the psu mounted on the top? those are only supposed to reach 2.7th/s on the default config. or do you mean the separate 1600w psu (if so those arent "new") they sell? that psu only runs on 220v power i believe so are you sure your using 220v and not 110v?? try using another psu with 4 pci-e power connectors and hook 1 up to the controller and the other 3 to one of the boards. power the miner on with 1 board at a time and see what the hashrate for each board is. this will help you determine which board has issues.
Completely useless suggestions.
First of all, he lives in a country where is 230V electricity .
Second. I'm pretty sure he bought 1600W PSU.
Thirdly. S9 software shows each blade separately. Hashing speed and HV errors.
There is no need to disconnect anything.
I got my first five S9 and one is also "lemon".
Tomorrow brings courier another 6x S9 . I hope they are better.
first how m i supposed to know where the kid lives?? silly boy think before you speak
second he wasn't clear that's why i asked. there's no reason to assume ne one has 220v power and since idk him personally i didn't want to assume pay attention
third you obviously don't mine much. those that have would know psu issues do come up. for example some times a power supply wont power on one miner but it will work on another one of the same model. i had this happen with 2 s7's i have. the psu would work on every other miner i had except one s7. i tried like 5 s7's and all worked great except for one miner. i had to use a dps-1200fb that i modded as the supply for the controller. the psu that wouldn't power on that single miner was an evga g2 1300w psu so ik the psu was more than beefy enough to power on the controller besides if it wasn't all the other miners wouldn't have powered on either. so before you go runnin ur mouth kid ask. don't say my comments r useless because frankly ur ignorant negative comments don't help at all. i was at least offering a suggestion to him and others like him. what did u provide?? absolutely nothin! so take ur bull elsewhere please or be more polite to your fellow community.
maybe s9's are just arriving dead. i wasn't stupid enough to buy s9's at the current price and risk tens of thousands of dollars until things had a better roi but that doesn't mean i cant try and help people that need it which is more than u can say based on that ignorant reply.
If you're smart enough not to buy the S9, why are you commenting on things that you do not have and of which you know nothing about ? Not smart enough for this ?I had 43x S7, burnt down 3 blade during the warranty period and 5 blade after the warranty period.
I have never seen a problem , that PSU working with one S7, but will not work with another S7. Then, the power supply is simply too weak. But 1600W Bitmain PSU can not be too weak for S7 or S9
I have now 11 xS7 with 2 x EVGA G2 1600W , 1 x Bitmain 1600W PSU, with 2 x IBM 2000W single PSU and 3x IBM 2000W double PSU .
The best mining results gives me 1600W EVGA and APW3-12-1600-B2 (old version , with 12x PCI-E cables)
