I’ve purchased a new MSI 945P Platinum mainboard for my computer because my old mainboard has failed.

I currently have a Cooler Master RS-450-ACLY Real Power 450 Power Supply which should be able to support my new mainboard with Pentium D 2.80GHz. I just found out that this mainboard needs 3 power connector in order to achieve stability.

1. 24 Pin Motherboard Connector
2. 4 Pin Peripheral Connector (or they call it molex)
3. 8 Pin EPS 12V Connector

I checked out my Power Supply and it doesn’t have the 8 Pin EPS 12V Connector!
I’ve looked around the internet and found out that I don’t need to replace my current Power Supply and can just buy a convertor to convert my 4-Pin P4 to 8-Pin EPS connector. It will maybe just cost a few dollars for that convertor.

The other thing I found out is….


My new MSI 945P Platinum motherboard only accept PCI-Express display card which I don’t have!
My old one is an AGP display card. Meaning I got to spend an unforseen extra few hundred dollars for display card.

I’ve learnt a very expensive lesson this time that is “NOT buy things in a hurry”. Look up on the Internet and check out all the connectors needed, and compatibility as well before making any decision. The amount of money I spent on upgrading my current PC cost nearly as much as buying a new one.
