Is there a way to predict when you need to replace a psu?

post #1 of 42
Thread Starter 
I owned the Thermaltake tough power 850w (w0131ru) for roughly 4 years and a half now. Im worried that this psu might die on me. Is there a way to find out how long I have until I need to replace psu?

I don't know, but PSUs like yours are much better than I think we give them credit for:

If you can smell smoke coming from your PC, it's a pretty good indication that it's time for a new PSU.

@ OP, determining when a Power supply is going to die, or even if it's the culprit during troubleshooting is tough. I think as long as your not pulling more power then the power supply can, supply, it's general life span should be good. 4 years isn't to long, and if your worried, you can always prep by getting a new PSU in your sights. Find a good price point and wait for it to hit, then pull the trigger. Replace, test for a few months, then sell the old one. =) thumb.gif

I had the same exact psu for 4+ years. I just replaced it last week with an hx850 because the fan started to annoy me.

A power supply can be bad and still be powering your computer and seem normal. Usually the first to go is the capacitors or the fan. Capacitors don't have to be bulging or leaking to be bad. They can still have good capacitance values but over time their ESR tends to rise which isn't good for the components in the power supply. Also, over a long period of time the efficiency can lower and on top of the dust that accumulates, they run hotter which can wear out the components faster. That's why it's important to never skimp on the power supply. You have a good one there.

Is there a way to find out how many watts my PC draws?
post #9 of 42
You have to have special equipment for that. I have a Kill-a-watt meter that tells me how many watts are being pulled and what the efficiency of the PSU is, it's fun to see how much stuff draws and it can be useful too smile.gif

Aside from buying special equipment, you can get the Kill A Watt meter which is usually very affordable:

 

http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001 ($17.99 shipped right now)

 

Plug your PSU's power cable into it, and then multiply whatever wattage reading you see by about .85.  This would be assuming that your PSU is 85% efficient while you're getting whatever reading you're looking at.  So let's say the Kill A Watt shows 350W while playing a video game (this is a likely power draw with your system).  You'd multiply that by .85 to get an estimation of how much power your system might be pulling from the PSU.  So, 350 x .85 is 297.5W.  Of course, this wouldn't be absolutely 100% accurate, but it would be extremely close to it.
