Buy and use a hardware power supply tester. ATX testers are inexpensive and readily available. If your PSU's are not ATX, please post relevant server, PSU, etc., details if you cannot find a tester. Run memory test and/or system test suite in motherboard firmware Setup utility. Alternatively, download and burn Memtest86+ to a bootable USB stick and run it: https://memtest.org/ Disconnect and reconnect the HBA from the motherboard, all power cables related to the HBA, backplanes, disks, etc., and all data cables related to the HBA, backplanes, disks, etc., clear the zpool errors, and test. If none of the above fix the CKSUM errors, move the OS disc and data disks to a known good server and try again. David
