Just my 2 cents advice to people who advice others. Just don't advice people by pairing a board with 4+1 power phase and with a 125w processor. Do you really think a board with a 4 pin atx power connector can supply that much power without stressting it? Even if the brands+ magazines+ some brilliant reviewer+ some advisors who recommend for name sake say it will work, its just going to stress the phase and the mosfets, eventually putting load on the processor's voltage supply. The board will be the least of your concerns as it will burn the processor as well.
A prime example from overclock.net:

This is exactly the reason why some advisors need to stop recommending just by cramping hardware within a price for the sake of it. Its the people's money that is getting wasted because of such advices and you obviously will blame it on something else because you obviously don't know how things work. Take extra care and do a proper research before blabbing about it.
For everyone's knowledge the board is MSI 890GXM-G65 but this applies for any board with 4+1 power phase put up in a ridiculous manner and supposedly "compatible" with 125w processors. I told to some people it needs 8 pin EPS ATX cable+ more/better phase control, but sadly people just won't listen.

What's the difference between 4+1? and 8+1? An overclocker names chew* puts it out in layman's terms:
Chew*@XS said:
8 +_ phase when implemented correctly requires less power to acchieve clocks,its cleaner power, it's not as stressfull on PSU, and is considered to have a longer longevity. I might add there are very few true 8 phase designs. Most are split 4 + 4.
4 +_ works, if properly implemented and kept cool, if not it will eventually blow up when pushed hard.
4/8 phase is made specifically for CPU voltage. +1/2/3/4/whatever is made for the memory so unless you overclock rams, it doesn't matter much (i said matter much- I didn't it doesn't matter at all). But if 4+1 is done, not only better mosfets+ phase are supposed to be used, but also the circuit needs to be made in such a way that there is no stress between the EPS ATX connector and the Phase to the processor. It adds up to the cost and hassles, hence 8+1 is better off according to *some* companies.
