bluebeam Posted September 12, 2009 Share Posted September 12, 2009 I want to swap out an existing 300w power supply and replace with the VX450. However, the terms are confusing to me. I am good to go with the 24 pin (PWR1) power connection exchange. What I don't understand is the existing MOBO has another 12v PWR2 pin. The connector from the 300w powersupply has P2 on the plug (there are four pins). Does the VX450w have a matching connector? It has 4/8 pin power connector. Can one of these be used? (I have no idea what P2 means in this case or P4.) Can I use this power supply with this mobo? Link to comment Share on other sites More sharing options...
Wired Posted September 12, 2009 Share Posted September 12, 2009 There's no guarantee that this PSU would work on a Dell system, as they're largely proprietary. You'd need to find out if the dell motherboard follows ATX v2.01 or higher specs. Having said that, if you do try it, the 4/8 pin power connector splits into 2 pieces, and you would use one of those.

bluebeam Posted September 13, 2009 Author Share Posted September 13, 2009 Thanks I tired it and appears to have fried my mobo. Stopped working. There is power and fans run, but doesn't post. I put the old one back in and still doesn't work. After much hunting around I found one of the memory modules had popped. I secured that down, pulled the battery and restarted. Got a checksum error on Windows and went thru that and reloaded the BIOS to default and then Windows ran thru a repair. Anyway, finally got Windows up and running and had to reset the date/time. I hate to assume, but if the loose memory module was my problem it doesn't appear that the Corsair fried my board and that I can go ahead and replace the Dell power supply. I am a bit leery after all that to try again. Any comments? Link to comment Share on other sites More sharing options...
