Question on Capacitor Aging?

post #1 of 7
Thread Starter 
3 part question.

When it asking about Capacitor Aging is it talk about motherboard/psu or both?

How much does this effect psu watts over time? This mybe a dumb question but I was useing this site http://extreme.outervision.com/PSUEngine to calculate total watts. It came to 655w but then just to see what 40% capacitor shot up to 900 or so lol.

Don't Capacitor have a average life of 10 yrs or is that pcb boards?

I'm not the brightest preson so bare with me lol.

Disclaimer: This is my understanding of the effect, I believe it to be roughly correct, but there are likely to be errors.

Capacitors degrade over time. Most good quality ones have a lifespan of 10 years or more depending on type. Electrolytics (the ones that come in plastic covered metal canisters) tend to start degrading after 5-7 years though. Heat makes them degrade faster, so the cooler running your PSU is, the less the caps will degrade. Initially the only thing you'll see is increased ripple and less effective voltage regulation, it won't affect the power capacity until there is significant degradation.

If you buy a good PSU with high quality capacitors, keep your PSU cool you will not see any significant trouble with it for 5 years, even at high continuous loads. Your 610 PC P&C unit should happily run the rig in your sig until it's so obsolete you can't even play minesweeper on it.

The calculator is referring only to PSU caps, motherboard caps can degrade also, but most good boards don't have electrolytic caps these days, solid state ones age better.

Thx Phaedrus2129! Also like to Say thx for all the time it must have took you do all that work in you'r link about psu!!!!

New system going look like this

i5 2005k oc to around 4.5

dvd wr/cdr

dvd r/ cd r or bd

1 560 ti mybe sli

around 10 + 120 fans lol

water cooling

1 sata2 hdd

1 ssd

pci card 56k yes dial up lol boo

mouse/keyboard

do you guys think Seasonic x650 $145.00 would be enough psu even for upgrades? or Seasonic x750 $170.00.

Thx again.

X650 will run that proposed rig with SLi 560ti quite happily. I'd recommend the 750 if you go for bigger GPUs or intend folding on it.

Keep in mind that cheap capacitors will derate faster. Quality Japanese electrolytics (like Rubycon, Hitachi, Panasonic, Nippon Chemi-Con, Nichicon) are the ones that can last a decade or more, assuming their temperature or ripple specs aren't exceeded.

Taiwanese and Chinese capacitors vary more in quality, but most budget units from respectable companies will have caps that can last at least five years. Teapo, SamXon, and OST are reasonably reliable in PSUs. For the record, CoolerMaster and Thermaltake budget units are not considered respectable.

Ultra-cheap-os will use garbage capacitors like CapXon, Fuhjjyu, BH, LCZ, and the like that have exaggerated specs, very short lifetimes (<3yrs), and may even be based on the old Nichicon formula that makes capacitors blow up due to excess Hydrogen gas.
