Hi all, I was wondering would anyone have any advice re: buying a replacement power supply for a Dell Dimension 4700? At the moment, I have the measly 305W PSU (I think...) that came built in to the machine. With the following componenets in my system: Graphics Card - GeForce 8600GTS 512MB 2.5GB RAM Original Sound Card (Creative Audigy 2 I think...) and a small PCI slot cooling fan everything runs hunky dory. However, when I inserted a PCI-E x1 sound card that I just bought (another creative, x-fi or something), the machine starts, but nothing comes up on the screen. I'm assuming it's a power supply problem. If so, could anyone recommend a type of PSU to buy for my PC? Something in the range of 500W maybe, perhaps more if you's think I need it. Don't really want to spend more than €100, whatever the equivalent is in dollars/pounds. Any advice would be much appreciated. I thought I'd ask before I bought anything, in case I buy something incompatible or something that doesn't fit!
