S17 Pro PSU Issues?

[BitcoinIntern]

Hi Folks,

Has anyone noticed issues with S17 Pro psu's. I have a bunch which have gone bad lately. Wondering if others are facing similar issues?

No details. All psu's should be the same.

But which  s17 pro model ?

the  50th
the  53th
the  56th

Which settings  ?

low
normal
turbo

Which firmware?

oem
aftermarket

What power voltage are you supplying  ?

210
220
230
240

If you have after market firmware  and are cranked to 65th using 210 volts I am not surprised.

If you run normal speed on a 53th machine using 235 volts  I would be surprised.

I have 15  53pros  that are perfect on turbo setting (about 57th) using a steady 226-232 volts.

So I guess there can be a lot of variance in what your gear is doing.

I had zero problems with the S17 pros so far, but mine run on a voltage regulator, and voltage is dead stable at 220v, ALL the 17 series both T and S have very little tolerance to the voltage, they prefer 220v, they might work well all the way down to 200v and up to 240v, anything outside of that range will cause them problems and end up toasting them, and that what I think your problem might be.

If your voltage is leaning to the lower side of the range mentioned above, running them on Low power mode MIGHT fix the issue since fewer amps might result in more voltage that is enough for them to run stable, but if your voltage is leaning to the higher side of the range I am not aware of anything you can go do except for buying a voltage regulator.
