Fan Surges...

I bought this case 3-4 years ago and I am still using the default PSU that came with it. I do not put the PSU under any extraordinary excessive load I just do day-to-day office tasks but lately I am noticing reving noises coming from the PSU upon boot for about 5-10 min. Then they go away and the system runs as normal.

I have dusted the case/PSU several times with canned air to push out all dust and stuff from the fan but I still get this revving sound each and everytime the PC is either awoken from a suspended/sleeping status or turned on from being shutdown. Which lasts for 5-10min each time until eventually it goes away...

Is this normal for PSU's now-a-days? to rev up and then rev down?

I never noticed the PSU doing this at any other time until recently having had the same PSU since its build and no other system changes done to the PC.

I do have a replacement PSU I bought when it was a good deal which is a 550W (which is probably way to much for my needs, but was a good deal so I bought it..)

Should I wait until this one dies? is there harm to my system by holding out? or should I replace now?

Before anyone says anything I did open the case and it is indeed the PSU Fan that is reving and not another fan, as mentioned above though it does go away eventually (after 5-10min).

Thoughts?

Definitely don't wait until it dies. If it's a crap PSU, it'll damage other stuff when it does.

Is the revving that I am experiencing evidence of a "soon-to-be" dead PSU?

If PSU is overheating it may spur the fan to rev up. The fan itself may be faulty. In either case, that is a crap PSU and I would upgrade it ASAP. Since you have a 550W replacement, assuming it's any good, use that instead. Don't wait. A bad PSU can damage everything else in the case.

good to know, ill plan to perform the swap out with the replacement PSU later today.

What are your impressions on a Rosewill Capstone 80 Plus gold 550W Modular PSU? It was on sale for $90 and states its got a 5 year warantee.....?

That's a good PSU.

That's a good PSU.

...at a fair price. Rosewill might not be your #1 PSU brand, but they are just rebranding a really good Super Flower PSU. Go for it, before the modular version stops being on sale, or you start thinking a cheaper PSU would be just as good .

Diablotek's garbage and others of its ilk, such as many Raidmax, Logisys, and Coolmax PSUs, are PSUs that will destroy your computer along with it, probably through a huge surge in its final breaths. Unintended user-induced destruction occurs with these units because users expect them to meet their rated specs, and they absolutely do not.
