Title: Need a help with rig Post by: koprobo on March 11, 2014, 08:45:19 AM Hi, can you tell me which PSU should I use for these rigs:
rig 1: 5x Gigabyte r9 270 asrock h61 celeron g1620 4gb ram 5x nonpowered x16->x1 risers OS: SMOS 1.3 rig 2: 5x Gigabyte R9 270 1x MSI R9 280X asrock h61 celeron g1620 4gb ram 6x nonpowered x16->x1 risers I ask this question because previously I bought 4x Corsair VS 650W, but these PSUs have only 2x pci-e 6pin+2 and this is my mistake because 3 cards from rig 1 I have connected on molex and I have a problems: sometimes 1 card in sgminer is sick, sometimes 3 of them are disconnected and have 511 degrees (sgminer, smos 1.3). I checked power consumption and 1st psu had 590W consumption, second had 350W. Additional power for pci-e slots on motherboard is connected from 1st psu (also this psu is powering motherboard and 2 cards). My 1st test rig looks: 1st psu - motherboard, pci-e slots, 1 card by 2x pci-e 6pin, 1 card on molex 2nd psu - 1 card by 2x pci-e 6pin, 2 cards on molex Is this a problem with my PSUs? I think yes but I must be sure that problem is in PSU, not risers or something else. On stock clocks sometimes everything is good with some rejects but sometimes I have sick card and other problems. |
