Wondering if it's safe to boot a computer without installed ram or hard drive / ssd.

Title. It's running an i7-7700k and a ASUS Z270E Strix Gaming Motherboard. Along with an NZXT Kraken X62. Fully modular Corsair 700W PSU. All the proper cables and things are hooked up and I want to know if it is safe to boot and see if the fans spin and if the lights light up without the ram or hard drive installed. (Those are shipping.) I'm anxious and if anything is wrong with it I want to know as soon as I can and I figured this might be the best time to do so, so long as it wont hurt any of my current components.

Enough blabber. To sum it up is it safe to turn on without ram and a hard drive? or will it explode.

And I'm really sorry if this isnt the correct place to post, really new.
 
Solution
It will not explode, but it won't boot either. It will probably power on, etc., but it's pointless to do so as all that will happen is that you will hear an error beep code and you'll get a no signal message on the monitor. There is no way you will be able to know if something/anything is wrong without memory, CPU, CPU cooler, GPU/GPU card. Hard drive is not required to POST and enter the BIOS, so that's not essential to troubleshooting or pre-troubleshooting the build, but at this point you are just wasting your time until you have the minimal requirements necessary to POST.

There is no way to determine if something doesn't work, without having all of the components necessary FOR it to work. Wait for the memory to arrive and THEN test...

What if you wanted to check you’d wired the fans correctly, I want to test my fans and only my fans
 
Why would you need to test the fans prior to having the other hardware installed? Is there some reason you suspect the fans to be faulty? You can't control the fan profiles without everything else operational anyhow, so it seems silly to want to check fan operation. I've never seen a case or CPU fan that didn't work out of the box, and have only seen ONE pre-installed case fan that was damaged (On a Phanteks Enthoo Pro) so I'd think you could assume they all work ok and simply wait until the other hardware is installed. It's not hard to remove a fan with the other hardware installed anyhow, so it's not like you're setting yourself up to have to undo a lot of work later on.

That being said, it should be ok to do that, but you also stand the risk of connectors shorting out on other stuff if they are touching something etc., that you don't have when they are all connected up properly. If you are really concerned about not having to go through a bunch of other work over again, then I'd simply bench test everything BEFORE installing it in the case, including the motherboard, CPU and memory.
