I have an Acer Aspire M1641 and I want to install a AMD Radeon HD6670. Are they compatible?

Yes they are compatible, but you would need to upgrade your power supply first. You do have the slots needed to add a Radeon HD6670, but your 250W power supply can't handle the card. You would need a good quality 500W power supply minimum. Personally I would recommend a good quality 600W-700W power supply so you have a little breathing room for future upgrades or additions.

I Want to upgrade my processor from 2.1 gig to a 3.3 gig, but the wattage jumps from 45w to 65w. do i need to upgrade my power supply and what and where do i find one? i have a 250w supply now.

No necessarily, the present power supply will be just fine, but if you will upgrade something else in the future you will definitely need a bigger one. Luckily it's a simple ATX PSU that can be bought at every computer shop 0 get a 400 watts one.
But you will need a much better processor cooler, the present one will be too weak to cool the new processor.

Doing the upgrade a power supply upgrade is also advisable since new video card like now requires a high power supply, upgrade the power supply to at least 500W and for a additional fan is already recommended to avoid any overheating problem.

I have an ThinkCentre M51 8143-14U and i wish to upgrade to a better power supply for a graphics card. But i don't which to buy because of different dimensions sizes and cords. im after anything over 500W.

There are only two different sizes of power supply commonly used that I know of and all power connections are the same as well.
I would suggest a reputable power supply that has specs for each "rail" in amperes not just 500w as there are many pwr supplies that do not "cut the mustard". You can research these in

Good that you are careful about the upgrade.
However you can upgrade your powersupply with a higher wattage rating without any problem. Increased wattage power supply does not fry or harm your system. The only thing that you should be careful before you buy the new power supply is its compatibility with the existing cabinet / case that you have.

Thank you for using
