Hey guys.
My current systems is as follows:

1156 LGA motherboard with i5 650 @3.2ghz

Sapphire HD 6850

2x 2gb ddr3 1333

120mm case fan

1tb 7200rpm sata HDD

500gb 7200rpm data HDD

DVD+RW

Will a 300w power supply be suitable or enough?

(If not, can I use two 300w power supplies with each other. What are the downfalls?)
 
Solution
A system with A Radeon HD 6850 needs 25 amps on the 12v+ rail and at least a 450w power supply with 1 - 6 pin PCIE power connection.

You need to use a single power supply.
