Fair product. The ElphaPex DG2+ 20.5G 3900W Running at full capacity with no drops. However, the cooling fans are quite loud — this is not for a home office setup. BullMiners did provide support though.

Satisfied with this purchase. ElphaPex DG2+ 20.5G 3900W is doing well mining LTC/DOGE. Getting stable performance numbers around the clock. I wished the PSU was included separately but overall great.

Reliable unit. My ElphaPex DG2+ 20.5G 3900W has been running for 2 months. The mining output has been very impressive. I had to update the firmware on arrival but nothing major.
