HP Store Online

Where can I buy a power supply for an HP Pavilion a800n?

The green light on the back of my computer will light up but it will not turn on when I hit the power button. I asked the people at BestBuy and they told me it was probably due to my power supply and I need to get a new one. Is there anywhere online I can purchase one at?

1. here is a good place. http://www.tigerdirect.com/applications/Category/category_tlc.asp?CatId=106&name=Power-Supplies
2. i wold say your best bet is going to newegg.com, also if u wanted you could buy a combo like i just did and it came with a new processor for a lot cheaper than buying both separately,
3. the a800n uses a 250 watt power supply. it only costs about $20-30 to buy a 300-watt power supply. (and not much more to buy a more powerful one) i would stick to well known names like antec or enermax. your hp's power supply was a bestec. not surprised if it blew...
