    PSU problem or Video Card problem

    Tried an additional BIOS change. Went to "AC BACK" setting and changed from "ALWAYS OFF" to "MEMORY". Disabled ErP. Continued restart into Windows from BIOS. Shut down PC from Windows. Restarted PC from Power Switch, same post error, flipped PSU off. However this time when the PSU was flipped...

    PSU problem or Video Card problem

    Okay, I think I am getting the picture now. The GTX cards had the 6 pin PCIE power connector which do not have the Sense1 pin. So it looks like a 6 pin SATA to 8 Pin PCIE power adaptor should be tried? I noticed that on for the cables that came with the PSU, at the PSU header there are 8 pins...

    PSU problem or Video Card problem

    I am not following why an adapter would be used? The Radeon RX570 Aorus 4GB has an eight pin power connector which I am connecting to a 6+2 PCIE connection on the HX850 PSU.

    PSU problem or Video Card problem

    The Problem Is Solved (Sort Of) Replaced PSU today. Started PC from cold start. No Problems. No memory error beep codes, no GPU error codes. Shut down PC from Windows. Re-started. Problem returned, requiring PSU to be switched off then back on to restart PC. Eventually I went into BIOS and...

    PSU problem or Video Card problem

    What is perplexing is that once the PSU is toggled off and back on, the PC starts up with no problem and no GPU problems. The other GPU's that were tested exhibited no problems, but they also were 10 year old models that had much lower power demands at startup than the RX 570. The RX570 does...

    Weird XMP Issue (AMD x570 board)

    I had a similar issue with my x570 elite. Disabling Power Down Mode in the bios allowed the speed and timing settings to be corrected by setting manually.

    PSU problem or Video Card problem

    Thanks for your reply. I've done all that, no change. Fortuantly Corsair has a 10 year warranty on the PSU. I'll see how things go when the RMA'd PSU is received.

    Memory is 3000 Khz. XMP settings run okay.

    PSU problem or Video Card problem

    The PSU has to be powered off (I suspect to discharge its capacitors?). When it is powered off then it's circuitry allows a power okay signal to the CPU to allow a start (I think?). If the PC is just only shut off normally by a Windows shut down I suspect the PSU remains charged until it's...

    PSU problem or Video Card problem

    My RX 570 4GB video card in the motherboard PCIE 3.0 X16 slot will only run with no problems if the PSU is toggled off then on before starting the PC. Once up and running, the PC will run for days with no issues, even over clocked. If the PSU is not toggled, the PC gives video error beep codes...
