PSU lifetime

[InfinityJosh]

I'm curious to know the lifetime of a PSU, does it vary depending on the use of PC? (gaming or office)
And for a gaming rig how many years would a 80 bronze PSU last? (for example a CXM750)
I read in other threads different opinions.
I had a SONY VAIO desktop 3.00 Ghz pentium 4 and it lasted 10 years with a default (crappy) PSU.
I used it for gaming Age of Empires 3 (it was a very demanding game for its specs) for many hours per day and the PC lasted until I had to replace it with my actual one.
Also Desktop PC usually have crappy PSU (HP and other brands want to minimize costs).

You can never really tell, I have seen complete trash chinabrands last 10 years and more of everyday use and expensive brands dropping dead in few weeks.
At least with more expensive brands you usually have good warranty up to 10 years.

It varies between 1 second and 20 years :)

Just buy a good brand with 10 year warranty and don't worry about it.

Seasonic Prime Titanium series.

Depends on many factors. Same as with any hardware.

I've had some last years, some only minutes.

I still have an old PC I built back in 98 running fairly healthy. It could die any day now. Or it could last me many more years. Granted, it isn't on all the time and only on when I get that need for nostalgia.

Honestly, I wouldn't worry about a PSU at all. Every single PSU I was using for around 12 or 13 years never let me down. I was using many PSUs - but for most of my computers they were cheap gaming alternative and PSUs were not the best quality as well. Still, they were working until I've changed them.

I don't know if I'm lucky or something, but still - wouldn't really worry for at least few years.

I have been using PCs since the early 1980's at home and work and the only PSU I ever replaced was an overrated OEM PSU that came in an HP PC I bought in 2004. Its supposedly 250 watt PSU could not even boot 130 watts after a mild graphics upgrade (measured max AC input with "Kill A Watt" meter after replacing PSU with conservative 330 watt).

On the other hand I tried my old GTX 550 Ti in an old Dell PC which had to use an adapter to connect (2) 4-pin IDE drive cables to 6-pin power to the GPU and its 305 watt PSU and no problems at 240 watts AC input.

I have heard of some people having their PSU go up in smoke or explode, but they must have been cheap or defective.

EVGA SuperNovaG2 is always Gold rated... the G stands for Gold while SuperNova also have Titanium rated PSU starting with T and so on.

SuperNova is a nice PSU and imo the only real good EVGA PSU line. With Corsair as they dont build PSU's themself their only good line are the SeaSonic Rebrands. But in that case you could go with SeaSonic in the first place imo.

Considering I have a nearly 4 years old rig I hope it would last another 3 years until I will replace the entire system due to surpassed technology.

Let me put it this way, PSU life can vary, no one can give you an answer, what you want to watch out for is the capacitors in the PSU as that can give you some kind of an idea, if any of the capacitors look bulge, that's not a good sign, if you start seeing smoke, also isn't a good sign, if you see a fire, you get the heck out of there, but for real it's just the capacitors you have to watch out for, if they blow up, or whatever.

Which CXM do you have since there like 4 versions of them ATM, all of them are really revision, 3 of them have green text, the newest one, and improve version is the gray version.
Green.

Gray

If you had the CXM for nearly 4 years, then I say it's the green version 1, or version 2, also you shouldn't worry really if it lasted that long, just means you got a good one out of the batch. Hope that put your mind at ease, but if you really want to replace it, get one that has 5, or more years for warranty.

It is a green one CX750M, I noticed is one of the worst of good ones.
I'll jump on a Seasonic next time, because I read is the best.

They're a good brand.

Look here for PSU's, might find one within your budget. I set it to 4 brands, with bronze and gold rated, with 500watts, or highier.

Here a Tier list for PSU made by the community, don't look at PSU below tier 4, you only want 1 - 4 tier, within each tier is brands, and then models. New PSU's came out not too long ago, so list haven't updated for those as of yet.

Here link to reviews to jonnyguru as he makes reviews, and score them also giving his opinions, not all PSU's are listed, so you have to ask if you need help to understand anything.

Corsair mainly sells rebranded chinabrand and Seasonic PSUs. But yeah, Seasonic is one of the better PSU brands.
