Does anyone know if HP is using a power supply that works with only a HP? I'vew tried two PS's from Pwer Up. Both died right away.
I have a HP Pavilion a1730n, running VistaHome Premium. Need to instal a PCIE card and the present PS does not have enough horsepower to handle the new PCIe cards. The machine has 2 gig of memory and presently the video is running fromn the motherboard.
Any suggestions... MONEY is a part of the final answer.
Thanks in advance
Rich bGo to any computer store with your old Power Supply.

Buy one with a little more horsepower that matches the dimensions of your CURRENT power supply.

Staples carries relatively cheap power supplies...it depends on what neck of the woods you're in.The Saviour < he's right on but; your gonna pay way more there or anywhere else in stores instead of online.... (look)
.... RETAIL stores are at least 25% more then buying online ..........
honvetops is absolutely correct...

It just depends how soon you want to get this thing. Are you looking to save bucks or are you looking to save time?I forgot about the I don't give a crap factor!!! I want it NOW!!! Power Supply Calculator

As to it being propietary i WOULD contact HP to make certain...
