In my server case, fans sometimes brake and stop working. I thought this to be rather natural as the server is running 24/7.

Now, my IT specialist adviced to buy a new PSU. My current PSU with 1000W was bought 3 years ago. He told me that technology very much advanced and that I could now buy a new PSU, which is able to keep the current more stable.

Any idea whether he is just trying to make money or whether PSU technology has indeed advanced over the last few years?

I don't know if he's trying to make money or is ill-informed but that seems like a strange solution to me.

Which brand/model PSU?

Which brand/model fans?

And when you say they "brake" you mean they just stop moving or they "break" altogether and you have to replace them?

If it is just PSU fan issue, you can easily replace it with a better silent/airflow fan.

As far as technology is getting better and more efficiency these days, I agreed to certain point.....most newer/modern home appliances, TV's, PSU's, batteries and other electronics consumes less power these days. My friend replaced his old home AC and refrigerator with a new/modern AC and refrigerator, and his utility bill cut in half this summer.......

Thanks for your messages. By "breaking fan", I mean a completely unrelated component (one of the fans that cools the harddisks inside the server. Actually, I just replaced the fan and it is working again.

My question is more fundamental whether my PSU could cause defects of other components in my server (e.g, harddisk fans, potentially even the harddisks itself, or the CPU). What I am told is that my "old" PSU does not keep current as stable as the new ones. Having said this, mine is only 3 years old, so was surprised that PSU technology advanced.

I don't remember the model for sure, but believe that I had bought an Antec (which is the same brand as my case).

Do you think there may really be a "risk" coming from my PSU and is it worth to make the invest?

In this case, I don't think that the PSU cause the fan to go bad. Regardless of brand/model/age of PSU, cooling fan do go bad by itself.......

Nothing inherent, no.

Thanks for your messages and glad to hear that there is no strong need for me to buy a new PSU.

Besides energy efficiency, do the more modern 2012 PSUs offer additional benefits?
