Should I Replace My PSU?

I bought a Corsair HX620 either at the end of 2006/beginning of 2007. It's been solid for me on 3 different systems. I'm not crazy hard on it, either.

I'm going to be upgrading my setup soon, and I'm wondering if I should go ahead and swap the PSU as a preventative measure. I have no idea how long PSUs should last, even if they are super high quality like the HX620. I'd love to keep it, but I would also hate for it to fail and possibly screw up some of my new components.

Just as an FYI, The system I will be building will -easily- be powered by the PSU, as was my last one. So it hasn't been working super hard through it's life.
 
No. Just run it until it dies, and in the mean time look for a good deal on a power supply to replace it for when it does. That way, you have minimal down time.
 
I usually make that decision by taking the following in account.

1. How close my current system is to maxing out the supply. I usually like a 20-30% buffer.
2. If the power supply is more than 3 years old I knock 10% of it's potential max, so in your case I would assume it's a 560w supply now.
3. Estimate what the new system will use. If it's similar to the old or won't cause me to use much over 80% of the supply's capacity at 100% load then I'll keep it. Otherwise I'll budget a new supply.

Good advice.
 
Sorry I've left this thread so dead, been busy. :)

Anyway, I'll probably run this in the box. Just a final check before I don't buy another PSU to replace my beloved 620HX.

1155 Mobo
i7 Proc (95w)
8GB Memory
GTX 285 (may upgrade in future)
1 SSD
5 HDD
DVD Drive
4 or 5 120mm Fans.

I'm pretty sure I should be good there, right?
 
Very good. You should have no issues.

Corsair power supplies are solid, its not likely to die, 3 years really isn't old at all for solid state electronics like a switching power supply. And it's going to take a very serious dual GPU rig to overload it, and even if you did, it would more than likely fail gracefully, voltage rails drop and have instability, blue screens, power off, or fail to boot.
 
I still have my hx520 that I bought in 2007. Didn't have any problems with an OC'd q6600 + 4hd's + oc'd 5850. Works fine with 2500k @ 4,5GHz + 3 HDs + the same oc'd 5850.

that psu is more than enough.
 
For sure, the HX series is a really quality PSU, when I walltest the top PC in my sig, I draw 350 watts at a peak furmark/prime combo run. So, you should be fine...and I've got 9 120mm's, a 160mm rear and 200? mm front - all red LED..lots of other unlisted goodies too...well, play on :D
 
My HX620 is still alive after all these years two. Used it for 2-3 builds. No plan on swapping it out unless I go SLI/CF which doesn't look like its going to happen.
 
I have the same psu and bought it around the same time you did. I have ran it in four different systems and my current rig in my sig with no problems.
 
i'm going to 2nd running on it till it dies, i've got a CM Silent Pro 600watt modular, thing is ~3 years old and running like a champ
 
If it lasted for this long without any problems, it will probably last much longer without issues.
and Corsair HX their top quality PSU, even more so than their TX series.
