  1. You may be right about all this electrical engineering stuff...but I still cant explain why these 3 other PSU's failed to turn on the system. Im wondering now that maybe its the new Core2 CPU / board that needed something extra?
  2. again: the CmExtreme600W wouldent even turn on the system. I also have 2 Antecs a 450W and a 550W (12V+ rated at 16A and 18A respectively) also neither would power on the system The BFG PSU is rated at 20A 12V+ (havent had a problem since) again: The BFG site calls for a minimum 20A of 12V+ his XFX 7800GTX needs even more (26A according to the site) and if you think thats bad.... check out thenew BFG 8800GTX that requires 30A or more (bottom left sys req.'s) http://bfgtech.com/8800GTX_768_PCIe.html
  3. MY BFG 7900GTOC requires 20A of 12V+ I used to have a CMExtreme600 but it only provided 18A on 12V+ It would "weep" instead of beep...a quick flash and then turn off had to get the BFG PSU
  4. you need more power Look up the specs on your XFX video...It requires 27A of 12v might wanna look at a BFG PSU
  5. Well I think I found it: This CM 600W (RS500 PCAR) isnt enough power for the video card! according to BFG it requires min. 20A +12v (28A for SLI)! cm600 is 18A .... guess that proofs the reason either a 450W or 550W ANTEC didnt even turn on (15A and 17A respectively) I looked quickly but didnt see any CM's rated at more than 20A ughh
  6. I havent had any random crashes...and I still cant verify that the 1.257v (which should be at 1.5) has anything to do with the not powering up issue that remains. It dosent happen every time..but when it does...I get a "weep" (noise like a partial boot beep) )lights flash for a fraction of a second then turns off. takes sometime 5 or 10 tries to get it to finally power on. Thanks
  7. Looks like its OK Thanks for all the great info!
  8. Will try the jump tomorrow ...thanks! nothing is in front of it...all that shows is this exactly: +12V = 11.960 +5V = 5.191 +3.3V = 3.363 +1.5V = 1.257 CPU1 Vccp = 1.291 again thats from within the BIOS "hardware monitoring" Thanks OK I managed to jump it on with a wire! now... Is there a chart to identify what I should be getting from each pin? Im getting under +12 on most and havent seen one +5 ( all are 4.88 ) Thanks!
  9. Will try the jump tomorrow ...thanks! nothing is in front of it...all that shows is this exactly: +12V = 11.960 +5V = 5.191 +3.3V = 3.363 +1.5V = 1.257 CPU1 Vccp = 1.291 again thats from within the BIOS "hardware monitoring" Thanks
  10. I am also curious now to identify this +1.5v setting how do I "jump" this green wire to ground ? Thanks
  11. Id think the bios readings on those values would be correct... Heres all the readings: +12V = 11.960 +5V = 5.191 +3.3V = 3.363 +1.5V = 1.257 CPU1 Vccp = 1.291
  12. I dont see the +1.5v value on that chart. going to get another PS to swap (I've added my system info)
  13. Those values were taken from the BIOS (not from windows)
  14. At hardware monitoring I have these values: +12V = 11.960 +5V = 5.191 +3.3V = 3.363 +1.5V = 1.257 the +12v and +1.5 seem to be lower than they should? And sometimes it just wont turn on! Thanks
