How long are PSU's good for? - Page 2

post #11 of 15
Antec TPT is when Antec put right the bad-caps debacle they had with some earlier TP power supplies, it's not a bad one by any stretch. A non-stressed PSU will have a 5 year lifespan easily, sometimes more.

No, the TruePower Trios were clean, it was the TruePower I and TruePower II lines that had the issue with Fuhjyyu capacitors.

Depends on use how long a PSU can last, I have a six year old Vantec Stealth 400W that's been running 24/7 for years in my home media server first as an Athlon 64 and then a Pentium Dual Core E6500 with two HD's and a Radeon 4550 without any issues other than a worn out fan bearing (easily fixed).

On the other side of the coin I killed my 500W Silverstone in just under three years by using it to power a very overclocked Q6600/GTX 260 based CPU/GPU folding box. The silverstone started making a high pitched wine for a few months and then just stopped working, no blown caps or any visible damage but it's dead Jim.

They will work for a very long time as long as it is running at normal temperatures. Over time, due to capacitor aging among other things, it's power output will be reduced and ripple supression/voltage regulation may worsen.

However, it takes many many hours of use for degradation to occur. A quality unit should last 10+ years doing very close to its rated specs.

All of my brand name power supplies still work, but I can tell you that if you have a really old one - it is burning more power then it's worth (IE: 65-70% efficient is common) I use only 80-85% efficient power supplies now.

Antec 350 watts (10-12 years old) - on a shelf, works 100%
Antec 350 watts (7 years old) - in an old PC, works 100%
Antec 430 Earthwatts (4 years old) - in my HTPC case
Corsair 400 watts (3 years old) - in my Home Server
OCZ stealthXstream 600 watts (2 years old) - works 100%
Antec 750 Earthwatts (< 1 month old) - Just got this one

The funny thing is I tried to run those Antec 350's to death but just couldn't do it. I carried the oldest one from PC to PC, finally retiring it with 400+ watts of load on it 24/7 and it was blowing fast/blow-dryer hot air out of it and I just couldn't kill it. That is when I bought the OCZ 600 so it would run cool, quiet and save on the power bill

In my cabinet @ level 3 I have 13 servers. All of the servers there had 4-7 year old power supplies by Sparkle, Antec, and others. I have replaced about half of them - but only to upgrade to 80%+ efficient power supplies. Just replacing 5-6 of the supplies in the highest load servers allowed me to place a whole new server in (I was out of available AMPS). Replacing the other half will free me up for another server.

ADDED: Actually, I had one 2U Sparkle 400 watt server power supply die on me about 4 years ago. But that is the only "brand name" power supply I've had die that I can remember. Most of the dead ones I come across are $10-$20 garbage ones that come with cheap cases.
