Last week my 5 year old motherboard died.

As a result I got some new hardware:
- New Motherboard
- New Processor (AMD Phenom II 965x4)
- 8 Gigs of DDR3 ram
- New hard drive.

However kept my case and 5 year old OCZ Game Stream 700 Watt PSU.

My question to the forum:

Should I keep the 5 year old power supply? or do you think as a precaution to protect my $600 worth of upgrades I should get a new PSU?

It is a good power supply, however I am afriad if it should go bad it could damage my new hardware. I am not sure what the life expectancy of PSU are. This one had a 3 year warranty.

It is still a good PSU but they age. The better the quality the less likely to take other parts with them. I would, if I had the money, get a new one knowing then that I will have a good spare if something goes wrong in the future.

I am just afraid of something going wrong with it and giving the system an unsteady current or a spike in voltage which could damage my new components. What is the likelyhood of that occurring with a 5 year old PSU?

Best to change the PSU (no matter how good it has been or still is) once the warranty associated with it has lapsed..

I would change it if I could...There are some plenty good PSU's on newegg for 80-90$ if your buying from there...for example...

Think of it as buying insurance. You just laid down 500$ on new stuff. And your old PSU COULD fry all of it. So you spend 80-90$ to ensure that either
a) won't happen
b) or if it does your new PSU has a warranty that should cover most if not all of the expenses.

If you have the money it's well worth it.

My basic rule is "New computer, new PSU." New motherboard, CPU, and RAM counts as a new computer.

OTOH, I have a 7 year old 400 watt Antec that is still happily chugging away.

"If it's past the warranty, get rid of it. If it's a lifetime warranty, well, then your in luck."
That's my motto.

I already have an Antec 650 watt TP3 for a spare - and probably the last two Corsair 400CX's that Amazon had in stock. :)

I got a Antec 300 watt unit from 2001 still running just fine in a core 2 duo system.

I guess I got one of the final 400CXs too, but from Newegg. It was ridiculously cheap, I think about $20 after MIR. Works great though.

Just wanted to give everyone an update.

I swapped out my 5+ year old PSU and I am GLAD I DID. I noticed about 5 minutes after I would boot up my PC these past few weeks it would start making this high pitched whinning type sound. Out of fear of the PSU shorting out I logged on to newegg and purchased a new Corsair TX650W.

Well I just swapped it out today and whola! My PC is totally quiet now. I feel so much better having peace of mind that my investment is safe.

Thank you for all of your input.
mgrzTX thanks for your recommendation on the PSU.
