Can under-wattaged components be at risk?

post #1 of 16
Thread Starter 
Under-wattaged (Made up word): Meaning - The PSU has enough AMPS to power components but the wattage may be borderline.

Ex given: I am powering my sig rig with a Corsair HX850, every now and then I get game stuttering and popping sound in my head phones from a cold boot. Upon a single reboot the problem goes away until the computer is powered on again from a cold boot (being off for several hours).

So if the amps are there but the wattage is not, can PC components be damaged? I know that I am probably pushing this HX850 to its max, but other than longevity of the PSU, are any of my other components at risk?

Thanks!


EDIT: I used the PSU Calc and it recommended 750wats, but other calcs recommend much much more.

Trying to figure out if I need to upgrade to AX1200 for the problem to stop.

Watts are volts multiplied by amps.

The psu outputs multiple voltages, one rail of 3.3 volts, another of 5 volts, and some more of 12 volts. These dont change much unless you are really stressing the psu to the point of bursting, or its a really terrible out of spec psu.

If you have enough amps on the psu, then providing the voltages are close enough to what they should be (even if they are poor they should still be), you have enough watts.

Electricity is supplied at a voltage, and amps are the current drawn. It only draws as many amps as it needs. Watts is the total power consumed.

As for the stuttering sound, what is your sound card?

I am using on board sound. I have both the 1/8" headphone jack as well as a set of USB powered head phones and gotten the same results.

Try a sound card. Onboard sound is very prone to doing strange things like this. On my laptop i can hear digital noises when i do things like scroll down if i turn my headphones up enough.

Yea electricity doesnt work that way your potential difference aka voltage will remain steady for most components and as you draw more amps aka current your wattage increases. Volts x amps = watts

And to answer your question, yes it is possible to damage pc components when you blow up the power supply feeding them. I wouldnt call it likely, but possible.

And i agree that your resulting analog audio signal from onboard isnt always isolated well and is a poor indicator.

These power supplies are engineered with protection systems built in. If you overload it, it will shut down before anything bad happens. I am almost 100% sure your problem is not power supply related.

Even if ripple was somehow getting into the sound card, it wouldn't sound like that. I'm not sure, but i think enough ripple to be audible would cause all kinds of problems with other stuff first.

So, would the on board sounds problems cause the frame rates in games to tank or stutter? Also I have BSOD before as a result of this problem.

Test your cpu and graphics card stability. Also test your memory. Reinstall all graphics card and sound drivers. Freezing up in the middle of a game with a sound stuck looping so fast it sounds like a buzz is usually something related to instability or drivers.


Download blue screen view and tell me what the error codes are too.

Edit: Check your temperatures under load too, make sure nothings overheating.

I am running the latest mobo bios (installed 2 days ago) as well as the latest drivers (installed 2 days ago). Temps are monitored by core temp and evga precision. Fan profiles are keeping GTX480s in check. H50 keeps i7 950 WAY below TJ MAX.

Could RAM cause these random problems? I mean, it happens on a cold boot. One reboot "solves" the problem. The sound is more of a popping noise and then FPS normally tanks.

I dont know if ram is the problem, but i would advise ruling it out. In my experience it goes bad far more than any of the other components do.

I'm not sure why it would only appear on a cold boot only though. How long has this happened for?
