They're made by Delta Electronics and are designed to work 24/7.
Voltage: 12V .Voltage can be set between 11V to about 14V maximum.
Amps: 150A, but they can hold up to 200A of continue load without any harm (tested for 2 days of non stop work under 200A load, but I honestly do not know how long would they work under such load)
PSUs come in different cable versions depending on your needs. I can sell them without any cables or with PCI-E plugs ready to work with GPUs or miners e.g. any Antminer.
PSUs do not have factory fans, because they are supposed to be cooled be air flow from server, so I mount additional high-flow fans on them.
Prices:
PSU with switch and fans - 45 Euro
PSU with 5x 50cm PCI-E 6pin plugs - 60 Euro
PSU with 10x 50cm PCI-E 6pin plugs - 75 Euro
Payment:
BTCTC or COD, escrow.
Shipment:
Buyer covers shipment cost. I'm from Poland and that's from where the PSUs will be sent. Exact shipment cost will be confirmed with buyer.
Sorry for my bad english, if you have any questions please PM me and I will try to answer:)
Are you using a DPS-1600 PSU? I thought it was rated for 1600 watts.
