Specs: Windows XP, AMD 2.7ghz, 2GB RAM
Hi! I have an IBM ThinkCentre M52-8215-D1U.

The official supported cpus list is found here: http://www-307.ibm.com/pc/support/s...

however, i want to upgrade to a core duo or something to save on power, the psu is only 225 watts! o_o also, the latest bios only officially supports what is on that list.

will my system work if i put, lets say, a celeron e1400 2.0ghz dual core in there?

thanks!

by the way, i don't care if the cpu is read wrong or if theres a message at post, and i can still boot into windows. so long as it uses less power.

if it doesnt work, what are my options to reduce power consumption on this poor little 225 watt psu?

"the psu is only 225 watts!"

Are you having problems because of it? It's an outdated system & has probably run for years with the 225W unit, so why all of a sudden has it become an issue? If you want better performance, add more RAM.

i got it only a few months ago, and i was curious about updating it the other day. it may have been running with 225watts for a while, but if i want to upgrade the os (itll run windows 7 fine except for aero, which i dont care). i put a 250gb hard drive in, and it has 2gb pc2-6400 ram already. its a nice system, the p4 is just a little archaic, thats all.

im expecting it to be on load a little more with windows 7, so im worried about the power supply. this cpu requires 84 watts, and the e1400 would be *at least* as fast, but use much less power at the same time (only 65 watts). it is also only 15 bucks more than a pentium d 820 on ebay.

so....

i guess this means that it wont work, and if i wanna save power, get a pentium4 631 or better. they use 65 watts, and they will work with my pc.

thanks all!

I don't know if it will work or not, but I think you'd be wasting your money.
