It began with me turning on my PC and launching a program, which gave me a pop up telling me that the shortcut cannot locate its source file to launch.
I checked disk management(I have one SSD and one HDD in my PC) and saw that the HDD was offline. Another pop up asked me to choose between MBR and GPT to initialize the disk but it didnt do anything no matter which option I chose.
SSD has the OS.
I turned off my PC and one by one connected HDD to other empty SATA ports while checking each time in BIOS if HDD was detected. It wasnt detected in all attempts.
So, I decided to swap SATA power cable(lets say A) of HDD with SATA power cable(B) of SSD. And this solved the issue. Both were detected.
To get to the root of the issue, I reverted A to HDD and B to SSD. The problem returned again, HDD wasnt detected and SSD got detected.

What I conclude from this is that, for some reason A isnt able to supply enough power to HDD(i guess it needs more power than SSD) but it can do sufficiently for SSD.
This shoudnt happen, right? Is my SMPS dying? Will it get worse and harm other components if I dont change is ASAP?

Components-

2. HDD > Toshiba DT01ACA100 1.0tb 3.5in (Jan 2016).

That's a horrible PSU. With 10A/120w @12v it's nowhere near a 450w unit. First thing you have to do is to buy a real PSU.
Thanks for pointing that out. I knew it was a cheap one but didnt knew about the fake wattage! Local computer repair shop put it in 6-7 years back when I had very little knowledge about PSUs and computer parts.
I hope upgrading it would fix my problem.
