I heard the X1900 XTX uses lots of power. Will it work on my PC with these settings? Power DC power supply: Wattage 305 W Heat dissipation 434.6 BTU/hr Voltage (see the safety instructions located in the Product Information Guide for important voltage setting information) 90 to 135 V and 180 to 265 V at 50/60 Hz Backup battery 3-V CR2032 lithium coin cell or must I buy a new supplier and if so, what is the cheapest one I can get?
You dont really want to go buying a PSU with the idea of getting the cheapest one, especially if you are buying a monster of a graphics card. Depending on the rest of your stsyem specs, it would be wise to think about getting another PSU. 300W may not be enough. Personally I believe it is best to buy a quality brand PSU (Enermax, Tagan, Hiper, Seasonic) to ensure good performance and system stability. Here is a PSU calculator (originally posted by Zeus) that will give you a rough idea of the size of power supply you will need. eXtreme OuterVision :: eXtreme PSU Calculator
Look for a good unit with at least 500W and the following: -Heavy -Dual 12V rails -30A or higher between the 12V rails The power supply is not something to skimp on. For what you have, budget between $80-120 for the power supply. Anything in this list is going to do the job. Right now, the Antec TruePower TPII-550 is just under $80 w free shipping. That's an excellent price for a quality 550W unit. Again, don't go cheap with the power supply. If you skimp on the power supply, you risk instability and long-term damage to the rest of the components.
Yea, an overloaded cheap PSU won't last very long and, unfortunately, when they go they go postal. There are horror stories of PSUs burning out and taking motherboards, processors, and video cards with them. This image was posted by AT to show why you shouldn't get a cheapo.
