Hi guys, I am upgrading my P4 (478 mPGA) computer to either LGA 775 or LGA 1156, depending on my budget (still not decided). My current system has a 20 pin ATX 2.03 PSU - 400 Watt with additional 2x +12V and 2x Ground placed in a shape of swuare (in 2x2). I was thinking whether I can use this with MSI H55M-E33 (H55) and Gigabyte GA-G41M-ES2L (G41) motherboards? If it is possible, then what are its pros and cons?
If not possible, is their any way I can use my current PSU using some additional brackets or something?
THANX in advance.
I would just dump your P4 era PSU. Not only is it not compatible with current boards, but its not efficient, and probably about ready to burst some caps. Just pick up a new quality PSU and not worry about it.
Modern boards use a 24pin ATX bundle, and either the 4 or 8 pin AUX connector. Yours has a 20, and the 4 pin. Your PSU simply can't send enough power to the CPU and motherboard. You can use adapters and such, but you'll only end up frying it.
