MSI Drops 125W CPU Support On K9A2 CF Board

"MSI has dropped the previous support of 125W TDP processors"

Search News

A little while ago, it was noted that MSI had removed 125W TDP CPUs from the support list for their 790X-based K9A2 CF motherboard.  This apparantly was due to numerous complaints from users with problems, one including an actual fire starting.  The people at bit-tech decided to query further and received the following response:
"[MSI] cannot guarantee the long-term durability of using a 125W part in the two year warranty". We were also told that "The original power design on K9A2 CF is limited to AM2's 89W and AM2+'s 95W [specification]".
Obviously this means that MSI decided to use cheaper components that would be unable to deal with the greater heat and voltage regulation stress of a 125W TDP processor.
125W TDP CPUs are hardly new, and there's also another 790X board on the market that supports them, though it is more expensive.  Also, this means that users will be unable to upgrade to the future Phenom 9700 and 9900 processors.
Do you think MSI made a sound business decision?

Lol yeah I knew the Dynex part was bad, but got it through a friend working at Future Shop for 40$ so it was a sweet deal. Anyways, on the box it says this:

Voltage: +3.3V +5V +12V1 +12V2 -5V -12V +5Vsb
Max Load: 35A 40A 16A 18A 0.8A 0.5A

Does that mean its got 2 12v rails? And therefore you're still unsure if its good enough lol?

yes that has 2 12V rails. But be careful of specs put on the outside of the PS. There are VERY FEW PSs that live up to their specs.

While it may be fine (or it may explode and take your hardware with it) taking chances with a poor PS is silly. Always start with a good one from the beginning.

I like single rail non modular power supplies best.

Take it this way, what part has an input into EVERY SINGLE component on your PC? Yes that's right, the PSU

Getting a bad PSU is like having a bad heart, everything else could be fine but the thing that pumps around the blood to the body breaks and your up sh1t creek without a paddle

Ok well if I get a new psu I'm gonna go for one that'll last me for as long as possible, so what brand do you think would be best to go with? And size wise, do you think like 750w would be good?

And actually, I'm thinking of maybe getting the Thermaltake Toughpower 1000w. Good choice choice for future proofing?

1000w is a little overboard i think, i'd probably go with a 600w, or a 500w and just upgrade the PSU now and then for my needs.

Alright thanks for the help

the 750 could run a crazy computer. PC Power & Cooling makes a very nice 750

I heard some reviews of the Thermaltake PS that were ok but I would way rather go PC Power & Cooling.

One thing about The PC Power PSs is they tend to run above what is printed on their sides (other companies run less)

The Corsair 550 is a great deal if you can find one and can easily run a pair of 8800GTs in SLI and a quadcore.

Well was looking around many places, and then found a guy near my place was selling a good psu cheap so I couldn't not buy it lol.

So I now got an OCZ EvoStream 720W and got it for only $125CAN. So I'm good to go. Thanks for all the suggestions and help guys, but I couldn't pass up on a good deal. Hopefully I made a good choice :)
