Dell precision 390 wont boot with a new power supply.

post #1 of 9
Thread Starter 
My friends dell precision 390 wont boot with a corsair 430w power supply in it, it will only boot with the default power supply. If the corsair one is put in it, a blinking amber light shows on the power button and it will refuse to boost. We need the new power supply to power a GTX460, what gives?

You may have a bad power supply. (At your own risk) you can short the PSU with a paperclip to test it and at least rule that out of the equation. Also make sure that all connectors are in place and you are not missing anything (did you check additional 4/8 pin on the motherboard?) Otherwise you may have a RMA on your hands

I don't think dell uses ATX for their PSUs.

Or get a 600W PSU from a precision T3400 off ebay, they are made by delta. Good stuff

Not confirming that itll work, just a suggestion

Um, ATX isn't a material, lol.

ATX is how the pins are arranged on the connector. Has no impact on weight.
