Can PSU Kill SSD

Can PSU Kill SSD? (5 Things You Should Know)

A faulty PSU can damage several PC components, but many people want to know whether a faulty PSU kills the SSD or not?

I have been building PC for the last couple of years, and I did complete research about PSU’s impact on SSD, and after doing the research, I have written this article to give you the appropriate answer to this query.

So, Can A Bad PSU Damage SSD?

Yes! A Bad power supply can kill your SSD, and even it can kill several other integral components like motherboards, hard disk drives, and CPUs because it is the primary power source of the system. 

Storage drives like Hard disks and SSDs are the most sensitive parts, and the PSUs often impact these devices; that’s why the experts recommend picking an appropriate PSU for the system.

The appropriate PSU doesn’t indicate the higher wattage; generally, SSDs don’t require too much power. So, check whether the PSU is capable enough to supply the required or not.

If you have another unit to test the PSU, it’s excellent, but if you don’t have another unit to swap, then take it to the local computer store for testing.

Other PSU conditions can also kill your SSD; these conditions and reasons are explained below. So, keep reading this till the end.

Why Bad PSU Kill SSDs?

A faulty power supply can harm your system in several ways. It can cause Display Issues, Computer crashing issues, Blue & Black screen issues, Noising, Freezing issues, overheating issues, PC won’t start problems, and in the worst-case scenario, it can destroy your system’s components.

Before knowing why PSU is killing your SSD, you have to know different types of SSDs and how they take power from power supplies. So, let’s check-

There are three popular types of SSDs available in the market- Sata 2.5″ SSD, SATA M.2 SSD, and NVMe M.2 SSD. All these SSDs require power, and they take power in different ways.

SSDs with a larger form factor need to be powered separately because these SSDs utilize more power. However, other SSDs take power from the socket they plug into themselves.

The SATA 2.5″ SSD is the only SSD that requires power separately, and you must use a power cable from the power supply unitNow, if somehow this cable gets damaged (Due to excessive heat or something else), your Sata 2.5″ SSD won’t get the required power. So, you have to check the cable in this scenario. To protect the PSU cables read this Here’s how PSU cables goes bad.

The other two types of SSDs, such as the M.2 SSD and the NVMe M.2 SSD, don’t require the power separately; these SSDs take power from the M.2 slot on the motherboard itself. 

Motherboards take the required power from the Power Supplies via a 24-pin cable, and all the integral PC components, including SSds, are directly attached to the motherboards.

So, suppose you are using a faulty PSU. In that case, it will be unable to supply the required power to the motherboard and other components, which can severely harm the components like motherboards, CPUs, GPUs, and storage devices like SSDs.

Besides that, you also have to check the 24-pin PSU cables connected to the motherboards because sometimes PSUs remain perfect, but the cables go bad.

So, you can notice how SSDs are taking power directly or indirectly from the PSU itself, and if the PSU goes wrong, then under-voltage protection and short circuit protection can kill your SSD. 

I hope you understood how a faulty PSU is killing your SSD, but wait for a second, not just PSU; an SSD can be damaged due to several causes, and all these causes are explained below.

Other Factors That Are Killing Your SSD

Besides the faulty PSU, some components can kill your SSD, for instance, the motherboard itself. The NVMe M.2 SSD and the SATA M.2 SSDs are directly attached to the M.2 motherboard slots, and if your motherboard becomes faulty, it could also damage these SSDs.

Moreover, excessive heat and firmware failures are the most common reasons behind SSD failures.

To prevent your SSD from failing, you can do a couple of things-

  • Ensures that the drivers and firmware are up to date.
  • Keep at least 15% of drive capacity free.
  • Turn system protection off
  • Ensure BIOS is operating at AHCI mode.
  • Enable optimize drives.
  • Disable Drive Indexing
  • Turn off “GUI Boot” in MSConfig.

Besides these settings, you have to check the ventilation; if the ventilation is improper, it could damage your SSD due to excessive heat.

New PSU Kill SSD: Why Is It & What To Do?

If your SSD is killed after installing the new PSU, it can be due to using the wrong cables. I have also faced this similar issue-

A few months ago, one of my friends bought a new 750W cooler master PSU and installed that into the system, and after powering on the computer, he realized that something was burning.

After that, he booted the PC and checked all the cables he had attached, but he noticed they all were in good condition. After exploring deeply, he knows his hard disk and SSD are killed.

Then he dives deeper into this and realizes that his previous PSU was semi-modular and the new PSU is fully modular, and he is using some old cables to the new PSU, which is killing his storage components.

So, if you are also doing a similar thing as my friend, stop using the old PSU cables because PSU cables are not interchangeable at all.

In some cases, you can use old PSU cables if they belong to the same model, but it’s always a risk because the cables’ voltage can be different.

So, it’s always better to never use a PSU cable from a different PSU. 

Can An Underpowered PSU Kill SSD?

In general, SSDs use very few watts, around 3 to the 5-watt range, so if you have an underpowered power supply with low wattage, then there is no need to worry about this.

But, if you have a cheap PSU from an unknown brand, these units don’t have the built-in current or voltage protection, which could damage components like SSD, Hard Disk, motherboards, etc.

Final Thoughts

It’s clear that a bad power supply can damage your system’s components, including SSD, due to overheating and voltage protections, but some other reasons can also damage the SSD. So, you have to check whether the PSU is killing your SSD or is it something else.

I hope this article is helpful for you and if you want to know more about Power Supplies, SSDs, hard disk drives, and other PC components, then follow this blog regularly.
