When To Change The PSU?

TheMailMan78 · Feb 7, 2012, 04:28 PM

When do you guys change your PSU? I've had mine for about 5 years. Just curious.

entropy13 · Feb 7, 2012, 04:32 PM

Mine are still months old.

I have no idea when they would be replaced.

Paulieg · Feb 7, 2012, 04:32 PM

I generally switch out power supplies once a year, but considering how good this XFX 750 black and Corsair TX650 have been, I've held on to them for a year and a half so far.

That seems to be the case with the TX series.

I'm surprised though. I really prefer modular. However, the TX is in one of the family rigs which doesn't get messed with much. Nothing but modular for my bench rigs.

AlienIsGOD · Feb 7, 2012, 04:40 PM

I voted 5 years, as my Corsair HX 1000 is still running strong after 4 years of usage

Totally cleaned it out and dusted the innards out too, so its almost as good as new. That and there has never really been a stress on the PSU, i purposely bought a 1000w so i wouldn't need to replace it for a good long time.

_ALB_R3D X · Feb 7, 2012, 04:45 PM

I trade a lot and this includes the PSU too
PSU won't reach 6-12 months at most but for the moment I think i'm settled with my CM Silent Pro 850W.
Maybe I'll switch it before 6months if I smell a good deal or I'll wait until it burns down the whole building...

yogurt_21 · Feb 7, 2012, 04:51 PM

I have an enermax liberty 620w that's still running one of my rigs, almost 7 years old now, I have several much older than that.

Now for my main rig, I buy the beefiest one I can find and hang onto it until it's no longer powerful enough to handle the load My current one is 5.5 years old and still going quite strong. In fact the next time I upgrade my rig it will likely be overkill to the extreme based on the current power trends.

Get a quality, highly efficient, large psu and then set it and forget it.

TheMailMan78 · Feb 7, 2012, 05:04 PM

Well if you look at my system specs I dont think I am even pushing what I have. I'm just wondering when I should do a preemptive strike and replace it.

sneekypeet · Feb 7, 2012, 05:15 PM

when you "feel" it is time

I usually find myself replacing them after they go, but I have an extra PSU or two on hand at any given time. If you are looking for preemptive approach, I will rephrase my first reply. When you and your wallet "feel" it is the right time. Don't forget, if the old PSU isn't dead it's sell-able. That can help offset the cost rather than waiting for it to die and be worthless to everyone.

Another good way to go by is when the warranty status is up. Even if the PSU is still good, you have no other option then but to buy a new one rather than working with the warranty for an RMA if it does go belly up.

Solaris17 · Feb 7, 2012, 05:29 PM

Considering the quality of todays caps My HX1000 will last awhile. I think its important to change lower end PSUs under high load ~2 years in. but the higher the quality I would push about 5. Personally. I take amps into consideration. Know how your PSU works. it may only be drawing 200watts. but if your continuously pulling 80amps from the same rail your going to wear it out.

WhiteLotus · Feb 7, 2012, 05:48 PM

When ever I feel I need more power to power my computer.

m1dg3t · Feb 7, 2012, 05:55 PM

Keep it clean and working within spec and it should last a long, long time. Having owned and owning several piece's of vintage audio/electronics i can safely assume that. Of course initial build quality is a factor as well, if you start with crap you end up with crap.

That being said i would only upgrade if neccessary, thing's like hardware change's may call for more capacity.

DRDNA · Feb 7, 2012, 05:58 PM

I only replace them when I need more power otherwise they stay unless they fail which my ToughPowers don't seem to do.

TheMailMan78 · Feb 7, 2012, 06:10 PM

I've been thinking about changing it just because its hitting that 5 year mark. Not for any other reason honestly. I mean I don't want it to go and it take the rest of my rig with it ya know? I mean at the VERY most it has 43800 hours on it. That's if I ran it 24 hours a day for 5 years......which I haven't. It has 100,000 life on it according to Corsair.

Sasqui · Feb 7, 2012, 06:10 PM

I pulled out a 10 yr old 420w PSU (20 Pin ATX) for a bench build 2 days ago. Worked like a charm. I'd only change for an upgrade, like others have said.

look at the caps then. if their flat and not bulging or venting roll with it.

ChristTheGreat · Feb 7, 2012, 06:13 PM

I voted 5 years, but my server has an enermax 350w PSU for about 7 years 24/7!

m1dg3t · Feb 7, 2012, 06:16 PM

Isn't MTBf calculated using the PSU @ 90% capacity and a given temp? So if you run it lower than 90% and keep it cooler it would last longer?

And if you are sooooper paranoid bust out the DMM and check the main's to see if they are still in spec

Yeah. No way have I pulled 750w for any period of time. And I keep it blown out of dust. I mean honestly I'm not gonna "upgrade" I was just wondering how people on TPU handle older PSU's.

Could I pull it apart and check the caps? Sure. But its been going good for 5 years now and they are Japenese caps. Good stuff. Pulling it apart might even CAUSE an issue. Had that happen once with an old amp.

Krazy Owl · Feb 7, 2012, 08:23 PM

I change them when they begin to be whinny, when the computer begin to strangly shut down or refuse to start when its humid in the house, and when the fan begin to be noisy. I still have an older psu that i have put in older p3 rig and its from the 90's 250w.

brandonwh64 · Feb 7, 2012, 08:28 PM

I have a 1994 AT (not ATX) PSU around here some were that still works, its 125W I believe.

Norton · Feb 7, 2012, 08:38 PM

My 600w Strider has been running fine for at least 3 yrs now

As many have said, I will consider replacing if my power requirements change... will definitely stay with modular units

dude12564 · Feb 11, 2012, 02:36 AM

I still have a 350W running, probably should upgrade though.

LAN_deRf_HA · Feb 11, 2012, 02:49 AM

Upgrade when it fails, or if it can't run your shit, or if it's so old there's 4 degrees of efficiency between it and current models.

Not for any other reason honestly. I mean I don't want it to go and it take the rest of my rig with it ya know? I mean at the VERY most it has 43800 hours on it. That's if I ran it 24 hours a day for 5 years......which I haven't. It has 100,000 life on it according to Corsair.

Worked like a charm. I'd only change for an upgrade, like others have said. __________________ Heatware
