I've been using a 330w dell power brick which no longer works properly. It powers the PC for about 30 seconds and then I get a black screen, I'm guessing it no longer supplies enough watts after that. I've seen people talk about it elsewhere.
Anyway, does anyone have any suggestions for a replacement? The link in the first post no longer works.
What's your system specs? I assume you're running close to 300w though. So options would be eBay another brick, or maybe look into solutions like the HDPlex 300w AC-DC and run it externally?
