27 vs 36 decibel HDD

[Lei]

Can't be, it was working last night. I played Forza so sipped enough gpu wattage too with no problem.

My PSU was 650w and I'm using 3900x with gtx1070 (250w together)

The room went dark, I think it's more about what happened inside the PSU than the PC

maybe the additional power draw from the extra hdd finally kicked the psu into its red zone so it decided to go kaboom?
wouldn't be unheard of

well if its a gutless wonder and/or just old its very possible that even a 250-300w can kick it into its red zone, wouldn't be unheard of either

Ok, so you mean a new PSU will fix it?
I've been peeking inside the chassis, cleaning and resitting every cable while waiting for the new PSU.

Btw, you mean the power went inside the PC. Could something be damaged. It was weird that the house fuse broke.

not necessarily.
competent psus are designed in such a way that even if the primary side shorts out it doesnt or at the very least shouldnt fry every- or anything on the secondary.
however, only one way to find out i guess - wait for the new psu

Ok thanks, if I connect pin 3 to 4 (black to green) while the 24 connector clip is facing me
.... Will I die?

And if I don't die, will a defected PSU break the house fuse again? I will have to ask the building guard to reset the fuse and I really don't want to contact him again today.

Edit : did the paperclip test on pin 4 and 5
PSU is dead.

Ok, sound meter and Ultrastar in the same place blue used to be:

26~27 when spun down to 0 rpm (parked) and humming at 34~35

It also reads and writes twice faster (7° warmer) WD blue seems to write small files better.
Here are WD blue, ran the test 3 times:

Ultrastar:

Looks like I better copy all files from 6tb to 18tb and sell it to get another ultrastar I really thought 7200rpm would be significantly louder, I was planning to buy 14tb 5400 WD blue, but thanks to @repman244 mentioned that we're mostly idle not seeking, I made a much better decision... and killed my PSU on the way, but learned about fuses.

while copying from blue to helium, can see ultrastar writes twice faster:
