Question does my PSU make my HDDs fail?

I have got a new Seagate 2TB HDD and tried it but after a couple of hours of work, my PC became slow and nothing could be executed and even my mouse cursor froze and the PC didn't want to work anymore until I unplugged the new HDD.
The HDD works perfectly fine on other machines.
But the PC also runs fine with only a 64gb SSD plugged in!

A thing to watch is the HD's activity light. Is it going bananas even though you are not doing any heavy access? That would do it.

I can't find the HDD Activity light (LED) on my PC
Any HDD inserted into the machine does the same thing to the PC.

Your PSU is an older design. Given the other components of your computer I guess it's also used before you got it?
Your components also make it work near its nominal upper limit.
Those factors combined I'd say that it's likely your PSU can cause problems, and even if it doesn't I'd suggest you replace it to a new one rated for at least 600W.

Fun fact:
In my first computer I also ran into HDD problems caused by the PSU. Not that severe though.
As I installed a second HDD the 50W PSU wasn't powerful enough to make both drives spin up when starting the computer. I had to switch it off and then quickly back on again to get the second drive start before the first stopped.
