Salvaging ANTEC EARTHWATTs 500w to a new build..Should I? - Page 3

That's why I've been contemplating so much...

Sure I can get a cheaper PSU.. but it's the fully modular feature that just grabs my attention tongue.gif

Grab a multimeter (set it to read DC voltage, over 12v), plug the black lead into a black lead on a molex line. The red lead into a yellow wire on a molex line. Give the PSU a load. If the 12v lines stay close to 12v (11.8v - 12.2v) then its safe to use it.

The EA500 is a good unit honestly. I say just use it. If it dies, it won't take anything with it, and it should still have warranty too so you could just RMA it with Antec.

I don't know...with many good power supplies I'd expect a low load +12V reading to be above 12.2V. And this isn't going to detect excessive ripple, though that's probably unlikely on this unit in this time frame, given the 105C OST capacitors.

Anyhow, I'd probably use it too. Original Earthwatts is pretty decent Seasonic stuff. It probably wasn't even stressed much before, and with just a Phenom II X4 and HD 6850 on it now, that's not really running it to the edge either.

I was just giving a ROUGH estimate on what to look for on the 12v rail. My TPN 650 shows 12.31v idle (system on) and 12.29v full system load (folding @ home). Just so long as its not too far away from 12.0v its fine though.

And yeah seriously, the EA500 is a solid unit. It's not as efficient as todays units, but that really doesn't matter all THAT much. It's still a good unit. If you're just going to toss it, I'll take it. tongue.gif

Been out a while, but just to clarify in case you come back or someone else reads this thread: high price and/or high wattage =/= good PSU, and also low price and/or low wattage =/= bad PSU. There are plenty of low priced PSUs in the 4-550W range that are excellent units.
