That is normal. Personally I leave my machines on 24/7 unless we have expected power issues. You may be able to set BIOS to turn on after power outage to eliminate the self-check but I'm not a fan of that. Also I prefer a UPS over a power strip.
Dear experts, The  powers of my 7010 SFF and monitor are connected to a power strip. I prefer to turn power strip off after turning off 7010. Here is a strange thing happened when I turn on the power strip - I can see the power indicator of 7010 is on, and then being turned off in 2 seconds. It looks like the 7010 does the self check when the power strip is on. After that, I need to press the power button of 7010 if I want to turn it on. I am wondering whether it is good for 7010 power supply or not. If it is not good for computer, any other ways to make change to this phenomenon?
