I've owned a Dell Studio XPS 9100 since it was purchased new in late 2010. My power supply is starting to go bad (loud, rattling noise) and I've removed the PSU to confirm that. I'm looking for a replacement, other than the OEM one. From reading through past posts on this very topic here, there are some recommendations for ones that places like Newegg sell. However, in looking at them, I'm not 100% sure of the fit, as well as if the area of the fan would be located towards the inside of the cpu case, as it should. I'd appreciate hearing from others who can make a recommendation for a replacement PSU. Thanks.
