I've had an XPS 8300 since July and I seem to have an occasional power supply problem. On four occasions, the computer shuts down and you can not turn it back on until after it is disconnected from wall power for several minutes. This behavior is consistent with power protection circuitry found in some of todays PC power supplies. Twice, this has occurred when waking the computer from sleep. I am not sure about the other two times as I was not there to witness what happened. My theory is that there is a current in-rush when the computer wakes which causes the power supply output voltage to sag and trip the protection. This may feed into problems that others have had with this model and freeze issues when waking from sleep.
I should not be over loading the supply as I have not added any hardware. I believe it is rated 460 Watts. My system is an i7 2600, single 1.5 GB drive, single DVD burner, 8 GB RAM.
Anyone else have a similar issue?
Do these computers use a standard supply or is it Dell proprietary (can I use an aftermarket supply)?
Most generic standard ATX power supply units can be installed, with either a 24-pin or 20+4-pin main motherboard power, as the XPS 8300 has an open back panel, with or without the on/off switch.
You should be able to buy a compatible power supply from either a local or online computer store.
Note: A power supply with four SATA power connectors, is needed.
