Q: Can I run this on a 280 watt Power Supply ,, http://www.microdirect.co.uk/(25401)Sapphire-ATi-Radeon-HD-2600-XT--256MB-DDR3.aspx
A: No, i recommend a 350-400 watt if you are buying just 1. 550 watt for 2. A 280 watt will only run a low system, remember if gaming you need a good processor and ram so a 280 watt one is out of the question if you are upgrading.
