Hello nitrag,   If a system with 1600 W AC PSU operates at low line 100–120 V AC, then the power rating per PSU is degraded to 800 W.  You'll have to use higher input voltage to take advantage of the 1600W PSU's     [URL]   Page 32 NOTE: PSUs rated for 1600 W and higher require high-line voltage (200-240 V) to supply their rated capacity.   Page 138 NOTE: When you have more than two GPU cards on your system, you will need two 1100 W PSUs installed on your system.   Please let me know if this helps
I just upgraded to 1600W in my PE T630 because I plan to run four GPU's. When testing two GPU's I initially got an error (PWR1006) about the power exceeding. I went into bios and disabled the alert and now I can boot. However, I can't understand why under Power Monitoring the "Failure Threshold" is 986W. Is this remnant of my previous 1100W PSU's? If so, how can I update? I'm going to purchase an additional two GPU's and want this sorted out first.  Hardware > Power Supplies Input wattage: 900Output Wattage: 1600Firmware: 00.3D.65/00.3D.64Part: 095HR5A01/095HR5A00I purchased iDRAC Enterprise license thinking it was a power cap set by the previous owner that was disabled in iDRAC express and I couldn't modify without the license but Cap is Disabled. I can only change the Warning Threshold. How can I get the Failure threshold to update?
1600W PSU - Power Failure Threshold too low
