bob16314You can check the +12V, +5V and +3.3V in the BIOS Hardware Monitor to see if they're in spec..Can also check in AI Suite during operation..If I remember correctly, you can set the older AI Suite versions to pop up an on-screen notification if a voltage goes out of spec, maybe a Min/Max reading and a graph..Need to set the Min/Max specs in AI Suite to what they should be.The voltage limits are:+12VDC +/- 5% = 11.4V - 12.6V+5VDC +/- 5% = 4.75V - 5.25V+3.3VDC +/-5% = 3.13V - 3.47V-12VDC +/- 10% = 10.8V - 13.2V+5VSB (Voltage StandBy) +/- 5% = 4.75V - 5.25VVoltage Regulation on page 29 of the Intel Power Supply Design Guide Version 2.92How can I check my power supply's 12v rail voltage in my motherboard's BIOS?Might also try the card in the second PCIe_X16 slot too if you haven't yet.
aka_STEVE_bPretty weird or extremely bad luck , considering you have a battery backup to provide clean power. Always possible the motherboard PciX slot is faulty- causing graphics card burnouts. ......or the PSU has a bad rail . ( as mentioned above ) .... or just real bad luck on cards ? Those seem like the only culprit possible.
Wooohahaka_STEVE_bPretty weird or extremely bad luck , considering you have a battery backup to provide clean power.

Those seem like the only culprit possible.See! I would agree with you there! But... if the graphics card is faulty, or the PCIE slot is broken... then I should have no artifacting if I connect the monitor to the motherboard directly right? I'm getting artifacting on the BIOS when I have it hooked up directly to the motherboard. https://www.youtube.com/watch?v=gEmgc4_oKLs
STR1D3R_2I haven't read the entire thread so apologies if this has been mentioned,Shot in the dark but have you tried switching monitor cables?
Cool GTXSTR1D3R_2I haven't read the entire thread so apologies if this has been mentioned,Shot in the dark but have you tried switching monitor cables? 1) Monitor & Cable as suspect. What kind of Cable are you using Asus PG279Q & DP cable ? Make Sure it is a certified DP 2) What other powered items are attached to the PC 3) 3 GPU later ... might be time to pull & closely inspect your MB ... for Any signs that something is damaged, shorting .... I'd at a minimum make sure nothing is loose or fallen behind the MB
WooohahHow would a display port cable damage the GPU? It only transmits information right? It doesn't share power
WooohahOk I understand now. Jeez... so how would one find the root issue? It sounds like a broken GPU or DP cable are side effects of a greater issue. Could the PSU be the main root issue here?
XrayMan Why this isn't in Gen. Hardware is a mystery I guess. Moving thread there.
WooohahI've been using my PSU for 3 years. I bought an EVGA gold rated PSU because I figured it would last a long time and wouldnt potentially have electrical issues that ends up shorting out other components :^(I even went the extra mile and got a good backup power source
