Other users here I have dealt with have reported that throttling will even happen at stock speed & with stock cooler; if I had the time to dig out the couple of threads in where this has happened on this board & variants, I would. The cases were directly related to VRM overheating and overloading; a 3+1 phase simply isn't capable of handling such high TDP processor, some companies like Gigabyte smartly restrict all their 3+1 phase boards to 95W TDP. A 4+1 phase would actually be significantly better (if good quality) as long as the CPU is at stock speed & using the stock cooler and it shouldn't throttle; the load is split so each phase handles 25% of CPU current as opposed to 33%, this is actually a big difference. The x6 is probably the most power-heavy AMD processor out there, moreso than the x4 despite same 125W TDP.
At the $55 price point there are more decent PSUs with much higher wattage while retaining same quality. For example, the Rosewill Green 630W at $50 right now - you can ask OCNers around here, this is one of the really good PSUs Rosewill has been able to come up with and it's priced very well. 80+ to 80+ bronze isn't a huge difference.
Then I suggest he get the 95w 1055T because as a "server" hosting 20 people I would be wanting that X6 over a X4. If the OP is still interested in going for the microATX form factor than I suggest this board:http://www.newegg.com/Product/Product.aspx?Item=N82E16813128490
Along with the 1055T 95W version. 4+1 phase and a 95W should be absolutely fine on that board and possibly even a slight overclock. Also this board supports AM3+ so if the bulldozer CPU's are in the TDP range then it could potentially be upgraded in the future. Whatcha think about that xd? Better?
As far as the Rosewill PSU goes, yes I'm sure it's a decent PSU and especially for it's price point. I have no doubt some people have good experiences with the product. I personally don't like Rosewill products because well.. simply put, most of their products just aren't very good in terms of quality. Once again, the OP can decide what he wants because now he has both options at his disposal.
