I have a 2009 Dell Studio XPS 435MT (MT = Mini Tower; see below), and it's current graphics card is a Nvidia GeForce GT240, which is getting long in the tooth. I currently can't pony up the $800-1200 to replace it (and build my own), so I decided to upgrade the RAM from 6GB to 16GB, and slap in a kick-a** graphics card to last me 1-4 years.
The system has a stock PSU, which according to the spec page on Dell.com (PC is at home, I'm away at school for the week), it has a 475-watt PSU.
I already know the card will work with the Motherboard, the card is PCI-express v.3, but backwards-compatible with PCI-express v.2, which is what I have.
My question is about the PSU. Is 475 watts enough for that card, plus the rest of the components? According to Newegg, it needs a 450 watt PSU as the minimum. Plus, I don't recall there being a power cable for the video card attached to the PSU. My current video card, I just had to put into the PCIe slot, and I was good to go. Is there likely a place for me to plug a power cable into the PSU for the video card? Or am I gonna have to buy a new PSU as well? I'm trying to get as much info as possible, since I can't get access to the computer until Saturday..
