Power Outage

[Hi P]

1.- Which of the following could die from a power outage?

 

Monitor, Motherboard, CPU, GPU, Storage.

 

2.- What could happen if an UPS / PSU doesn't have a wattage regulator? (or something like that)

 

Thank you

hard drives might lose some data if you were copying or moving files

cheap power supplies might fail

old monitors weren't as bitchy with power as new ones

 

only a dirt cheap PSU died on me because of an outage

I'm assuming you're talking about a brown-out  - the flickering on and off.

 

From what I know, Brownouts can damage your PSU directly. If you have a good PSU, it'll stop undervolting the rest of the components and shut down power completely.

The undervolting can damage other components such as storage (And perhaps the others as well). (Just listen to what JonnyGuru Posted below. He knows his stuff)

I'd really only be worried about PSU and HDD storage.

 

Adding a UPS (for brownouts) renders them unimportant - you'd run as normal.

For black-outs, you'd just need a high-enough capacity to shut everything down.

 

Take the data component damage with a grain of salt - I don't know my PSUs all too well; however, I'll link @STRMfrmXMN and @jonnyGURU

Brownouts don't cause a PSU to undervolt on the secondary (DC) side.  The voltage is still regulated on the DC side regardless of the voltage on the primary side as long as the input voltage is within the range the PSU is specified to operate on and the bulk capacitor has a charge.  If the voltage drops too much and there's no juice in the primary cap, the PSU should just shut off.
