Answer» ill look AROUND for another power supply and let you know how it turns outQuote from: patio on May 26, 2007, 07:00:32 AM I'd like to know how the PSU was tested and FOUND to be OK... I DOUBT this way but I ordered mine from this guy and got it today http://cgi.ebay.com/LCD-ATX-Power-Supply-Tester-From-Apevia-20-or-24-Pin_W0QQitemZ140120729727QQihZ004QQcategoryZ44949QQcmdZViewItem Great deal! If you do a lot of PC bench work or service calls this is a must have. Newegg also has them.Quote from: TrapperX on May 26, 2007, 11:09:37 AM Quote from: patio on May 26, 2007, 07:00:32 AMI'd like to know how the PSU was tested and found to be OK... What does it do besides check VOLTAGE? Quote from: WillyW on May 27, 2007, 12:47:43 PM Quote from: TrapperX on May 26, 2007, 11:09:37 AMIt just puts a LOAD on the power supply to check if the voltage is within the system parameters. What else would you want to check with a power supply? QuoteQuote from: patio on May 26, 2007, 07:00:32 AMI'd like to know how the PSU was tested and found to be OK...

What else would you want to check with a power supply? Exactly. I'd want to test it under the rated load. I didn't examine the description closely, so I didn't see where it mentioned that it could test under load. Just testing for correct voltage - as with a VOM - is nice, but doesn't prove enough. A well designed power supply must be able to provide the rated DCvoltage(s) at the rated load, with a nice clean, flat signal. As the load increases, that's when problems can show up. |
