I'm having problems with my new power supply - or more likely when I installed the new PSU I stuffed something up. :redface:
The new psu is a Corsair vx550w - so 550w and more importantly 41A/492W on the 12V rail (full stats - http://www.corsair.com/products/vx.aspx
I recently had to upgrade hubby's motherboard & cpu - and at the time we couldn't afford a new graphics card (old one was AGP) - a couple of weeks ago we picked up a Point of View GeForce 7900 GT (our budget only stretched as far as the 8600 GT and since we didn't need dx10 I figured the 7900 was a better choice). Needless to say the old PSU was not going to be capable of running the card (aside from the fact that I was already running 1 hard drive externally due to a lack of power connectors). So finally today the new PSU was bought.
I hooked everything up (yes I do have experience and know what I'm doing - plus I also rechecked the manuals for the mb & psu just to be on the safe side) only to find that while I could get the system to boot and get into windows - after a few minutes it would just shut down - no blue screen no errors in the event logs - just no power).
At first I thought it may be an issue with trying to run too much on the psu - even though I did calc the requirements prior to purchasing. Needless to say I unplugged the graphics card first - with no luck - after some trial and error - I have the system running happily - however currently the dvd burner, floppy drive & video card aren't installed - I've also unplugged the front usb ports, power & hdd led's and the reset switch. Tomorrow I'll probably try plugging the dvd burner & floppy drive back in (hubby wants the floppy drive don't know why but hey) - and if that's successful I may even try the graphics card again.
In the meantime have I underestimated my power requirements - and if not does anyone have any suggestions on what else may be causing the problem.
System Specs (don't laugh it's a budget pc that will become a file server once new systems are purchased - already got a small mod planned for the one we're getting later this year :) )
MB: Asus P5GC-MX/1333
CPU: Intel Duel Core E2160
RAM: 1 x 2048 GB Corsair DDR2-SDRAM
Graphics: Point of View GeForce 7900 GT (if I can get it in & working).
2 SATA HDD & 1 IDE HDD (1 of the SATA's can be run externally in a powered bay if necessary)
Onboard Network & Sound,
some cheap keyboard (usb but connected to ps2 via adaptor) & mouse (ps2)
Any help/suggestions would be appreciated.
Thanks
