To be safe I would choose about a 700 Watt PSU, definitely no less than a 650 Watt model.
Yes, but you need a 5000 w power supply with an AMD Radeon HDD 1 Million.
The minimum system memory required for the ATI Radeon HD 4890 is 500 Watt or greater power supply with two 75W 6-pin PCI Expresså¨ power connectors recommended.
Not likely as the power supply is only barely enough to power a Nvidia GT600 series card.
Yep, that should be working fine. Just connect the 5770 to a PCI slot on the motherboard, and connect the power PCI power cable from the graphics card to the PSU (Power Supply Unit).
yes you can run the radeon 6570 on a 300w power supply but it all depends not only on how much draw your cpu has but also your disk drives and fans example the core i3 has a power draw of 64w at max load so with the i3 you would be able to use your power supply or you can check to make sure on extreme power source calculator where itll tell you the estimated amout your total system will run at with that card in there with your components i hope this helps
The 6850 is better but consumes more power.
5770 beats the 6450 in every benchmark except power consumption
You need luck and thets all u need
UPS = Uninterruptible Power Supply
ATI Mobility Radeon is a HD 3D graphics card that provides services for laptops and netbooks. It is small and light enough for such products, but offers high power and great visual affects.
power supply is a device that supplies electric power to electrical load
