jwr_vt Posted August 31, 2009 Share Posted August 31, 2009 I have already returned my MoBo and Intel CPU when I got no beeps at POST, to no avail. Are there som simple voltage readings I can test to verify if my TX750w (USA) is healthy or not? I have an AS in electronics, so I know how to use a volt meter. Thanks, Jim Link to comment Share on other sites More sharing options...
Wired Posted August 31, 2009 Share Posted August 31, 2009 The lines should be within 5%. Test each line with a ground of course. Before that you may want to save yourself some time by doing the paperclip test (check the stickies). Link to comment Share on other sites More sharing options...
jwr_vt Posted August 31, 2009 Author Share Posted August 31, 2009 Do you know where I can find the pin specs for the TX750w so I know what voltages I should read? Also, is it a valid test if the mobo connector is not connected to anything? Thanks Link to comment Share on other sites More sharing options...

PCCstudent Posted August 31, 2009 Share Posted August 31, 2009 Jwr, I easily found a 24-pin out just "googling" around for the connector.You can buy a P/S tester on Amazon for around $11.00, different LED's will light up when power or ground is present. Just go th Amazon and do a search for 24-pin connector tester http://pinouts.ru type ATX12V 2.0 into the search and you will be directed to a link,click on the link.

jwr_vt Posted September 1, 2009 Author Share Posted September 1, 2009 I'm trying to debug a possible PSU problem by measuring voltages on the 24 connector, but the PSU in not turning on unless it is plugged into the MoBo. Any tricks to getting the PSU to fire up with the 24 pin connector unplugged? Thanks! Link to comment Share on other sites More sharing options...
jwr_vt Posted September 1, 2009 Author Share Posted September 1, 2009 Never mind....just found the instruction about grounding pin 16 Link to comment Share on other sites More sharing options...
PCCstudent Posted September 5, 2009 Share Posted September 5, 2009 jwr, I wanted to test my 6 push/pull radiator fans and my other 7 case fans so I just used a free molex cable off my TX850 that was running another P/C. The P/S was running the server just fine and did not even notice the molex cable was powering up fans on another PC. Electricity is like that,it did not care its resources were being used for a neighbor P/C. This 4U server case is so large I can fit a full ATX boad init and a 6.75X6.75 mico board (like a Intel Atom) and I believe I could power everything of the same TX 850. My P/S are not modified in any way that make them look different,it all how you cable the outputs. I need to get a Atom board and see how the power plug is set up. Several come with P/S's in the 90W range. Link to comment Share on other sites More sharing options...
