Hi

Suddenly @ 13:30 GMT+2 on the 22 of August, my PhoenixMiner reports error

GPU1: Starting up… (0)
GPU1: Generating etchash light cache for epoch #223

As far as I knwo we are far ( 1 year ) from being at epoch >DAG file siez is over 3 GB

Other miners continue to works ( lolminer )

I tried 5.7B and 5.4C also

Any idea ?

As this PSU had evident thermal regulation problems, the seller fully refund me. Wanted to share it.
Waste of time, but not of money.

Thanks for your help 

$100-150 extra for Corsair ? Huh it's more like $300
Indeed I need 6/8 pin connectors

Troll ?
This 1200FB is known to be the best mining one. Unfortunately everybody need it, so it becomes hard to get a rock stable or brand new one. Not ready to spend $350 in 70% exploited PSU
Is there any PSU not chinese in the world ? 

PSu is refurbished, taht is for sure, the 12V golden plate of the PSU has evident shape of wearing.

Here's informations about it

I am currently printing a 40 to 70mm fan duct to set an additional air extraction with a 70mm Delta fan.

Ok, working on it AliExpress seller, hope it will go well
No I am based in France

@Bastonxl

Component should be indeed very hot inside :/
750W + 750W was my fallback idea

Thanks @

Hi community

I just bought at a chinese retailer a DPS-1200FB PSU.

It sounds to run normally except that :

1° When powering on, it does not do the usual cycle with fan running @ max few minutes. Instead, it stays quiet, running at very low RPM, almost impossible to hear.
2° When loaded ~600/700W, the fan remains at the same stock speed than without any load. However the metal case become very hot. ( Impossible to let finger more than a second on )
To prevent any frying I set on top 2 heatsink cooled with 120mm as a temporary solution.
3° Last but not least, output airflow smells hot compound, something like fried than shouldn't be that much to my mind.
I don't tell it's burning, but it has sucpicious smell.
4° The more I let the PSU without cooling, the more my rig tends to crash

Do you think this PSU has been tweaked and sold with low noise adjustment for popular need ( noise killing )?
Is it about to die because of worn out ?

Any advice appreciated and moreover the mod consisting of raising fan level

Friendly
