Hello, I want to install my new graphics card (Sapphire Radeon HD5450) but I need a 400w power supply, I currently have a 240w. The thing is my power supply is a funky shape (picture a small rectangle with 1/4 taken out of it). it has to be 6 pin, I am actually surprised that this power supply is powering all the stuff I already have in my computer.

As I said before, my power supply is a weird shape and no other power supply fits.

Can you post a picture of it and estimate the dimensions? It will give us an idea of what type of unit you have in there. HP doesnt make their own units, they have someone else build them they just put a sticker on and throw it in their system.

The HD5450 will run fine on 240 watt PSU regardless of what the card manufacturer says. Here in this test they have a total system power consumption of 143watts under load http://www.anandtech.com/show/2939/3 (power chart is at the end of the page)

That may give him less than 25 watts to play with, depending on the efficiency of the unit. (Assuming 70% here as it doesn't look certified).

240 watt power supply delivers 240 watts at the DC end, it pulls more from the wall!

Just to add a little more info. I have a HP DC7100 with a 3 GHz processor and 1.76 GB of RAM.




P.S. I also noticed that my motherboard has a mini-24 pin connector.
