I broke my psu

post #1 of 2
Thread Starter 
so, i broke my psu. i have a Thermaltake Purepower W0100RU 500W.

ive been reading this thread which says that my psu is only able to put out about 430W. http://www.overclock.net/power-suppl...take-psus.html

before anyone says anything, yes i know i was naive to run my sig rig with a low wattage psu. i will be buying a quality seasonic or corsair psu soon.

this psu has been running my sig rig for about 3 years now and i never had any problems with it until recently when i started running boinc. looking back, i realize that i didnt have enough power to run my components at that level, but shouldn't the psu have turned itself off when it tried to draw too much power? it ran boinc for at least 24 hours before the computer shut off.

i've already pulled it from the computer and tested it with a digital volt meter, so i know it is dead. the fan doesnt spin up either. i started the rma process with thermaltake and will be shipping it out tomorrow.

since thermaltake psus are hit or miss quality at best, when i get the rma back, i want to test it before i put it back in my rig or sell it. i know how to test the voltages on all the leads since i use mulimeters and o-scopes on a daily basis for my university classes. but i also want to test the ripple under load. my question is: how can i place a psu under load so i can measure the ripple.

AFAIK if you want to measure the psu, you should use a testing machine that does it all for you (and they are very expensive). These machines put very large amounts of load on a psu and can test it to 100% capacity. I guess you could do a few tests with a scope if you plugged it into a board and ran something in order to create some load. You wont be able to put the psu under full load (but do you want to?). As for an artificial load that isn't a computer, i guess its possible, but probably very complicated and i wouldn't recommend it.

Personally i would just sell the power supply and buy something decent. I ran a similar machine on my 500w for 2 years without a problem. What i have now consumes even more power and still seems to be running perfectly.
