It may very well be that it's not failing so much as that it is simply incapable of providing enough electricity to power all components under load anymore, so of course the component that fluctuates the most (and is deeper in the list starting at POST and onward for startup) is going to bear the brunt of the deficiency and the malfunctions that come along with that. but the most demanding component(s) are naturally going to fail first, which almost always points to HDDs as your first bet because of the reasons mentioned above.Įdit: Also, you can buy PSU testers from most computer retailers like Best Buy, Frys, maybe even Staples that can definitely address your query about figuring out if the PSU is actually failing.
A faulty PSU *may* fry other components, but it depends on how off-spec it is. Platter drives have lots of things working against them to cause failure, more so than the vast majority of other components, so their likelihood of failure is dramatically higher than everything else in most cases. So the Mobo and CPU are going to be either low-power requirement, or stable power draw while HDD spins up and down and up and down, over and over frequently. Also, HDDs are the only components that have significant power draw variations aside from optical drives once a machine has started up, as newer CPUs don't use much to begin with, and pre-Core I-series chips from both major vendors really only had on and off stages for power draw. This includes fixed drives, logical partitions, mapped network drives, and temporaryĭrives that you create by using the New-PSDrive cmdlet.Can a power supply kill a hard drive? Short Answer = YesĪ old PSU is most likely to kill HDDs first, because HDD's are the single highest power-sucking component in most computers unless they have very old CPUs (like Core2 Era or older).

You do not need to restart Windows PowerShell. Windows PowerShell automatically adds a PSDrive to the file system that represents the new drive.
