Power your computer with this Insignia™ NS-PCW5250 power supply, which features 520W of output power for enhanced performance and a 140mm low-noise cooling fan to help ensure efficient operation.
I have to say I am very unhappy with the recent service call which replaced the power system only to have the computer break down again a month later. Last year we replaced the hard drive for the second time. This computer has been a problem since day one. I would never buy another product from Best Buy.
