Upgrading both my boys' X1s for xmas to i7 4790k. Dell support said I need a 330 supply, but couldn't provide a model number. Intention is to upgrade video card as well, so may just get a larger power supply just in case. I want to ensure compatibility though, what do I need to look for? Do I need to specifically get small form factor? Is there a specific type of connector required for mobo, proc, etc?
