Hi all,

How much power needed for MSI board? If it's 100W per channel, and I have 5 channels, do I need to make sure that my PSU has at least 500W just for the speakers? Plus whatever is needed for chipset, cpu, HDDs, etc? From my readings I see that people are often using lower power PSUs.
 
Power is dynamically managed. I am running a 450W with no problems.

I have a TT power supply, but I think I like the Corsair a little better because it seems to be more quiet.
 
Not 100% sure but i'm willing to bet that those are fake pmpo watts, not actual RMS watts.

I'd be surprised if it were more than 20 or 25 watts RMS per channel, maybe even as low as 15 watts RMS.

Note that even 15 watts RMS per channel is still enough for most speakers on the market, especially the sensitive ones. Probably wouldn't be loud enough for a frat party though ;)
 
Trust me, it is more than loud enough for a party.

I have a 2 story, 3400 sq. foot house and 1/2 volume is loud enough to hear it clearly in any room of the house. Full volume and you have to raise your voice to be heard if you are in any room close to the HT room where I have it.

Yes, my floor plan is somewhat open in that my HT room sits off the foyer of the house which is open to the 2nd floor. But, my HT room as a low ceiling, carpeted flooring and heavy drapes over windows and a lof of heavy padded furniture. It can soak up a lot of sound. Room has a single door opening (more of an office than a true HT room.

Plenty loud and still clear. No distortion, no pops, hisses or crackles.
 
That's good to hear Javabri. Assuming your speakers have average sensitivity then it may actually be 25watts rms per channel, or higher. If your speakers are very sensitive (such as the klipsch HT or Cerwin Vegas) then it can still be as low as 15watts per channel.

I'm sure someone has already posted actual numbers at AVS, i just haven't stumbled upon that info yet.
 
I am running Infinity Primus 160 for L R and Infinity C250 for center, with Definitive Pro Studio 1000s for the rear surrounds. Sensitivity on the speakers is around 90dB.

Sub is Polk 12"

Not a super high end speaker set up, but it sounds great to me. More than enough power to meet my needs.

UPDATE: Just re-read your post. Did not catch that we were talking FRAT party. In that case, I would agree, probably not enough juice to power a frat party. But for us older folks, I think it would handle an average party crowd without a problem. As for general HTPC use, this thing rocks in my opinion.
 
There's no such thing as "watts RMS" anyway.. what they actually mean is "average power output", or "mean power output". There's no root mean squared measurement for power.. that only relates to current and voltage. It's somewhat of a gimmick term, because it looks cooler on the box I guess, and they can fool non electrical/computer engineer types of people with technical abbreviations.

With that crap aside, any decent quality power supply will work quite well. Going with a good brand like Corsair shouldn't pose any issues. A home theater PC system itself shouldn't be using much over 120w to 160w assuming you use a 65w processor in the unit, so having a 350w to 500w PSU will give plenty of overhead for the audio amp card.
 
Sorry to resurrect this one, but I just got my board yesterday. Sadly, I ran over budget and didn't have any $$ left over for a PSU. I have an Antec 350 Basiq that I hope will get me through for a month until I can replace it. I paired this board with an AMD 5050e, so for once I am trying to go low power instead of balls to the wall power suckling pig, so we'll see how it works out.

Hard to believe that my original HTPC rebuild budget was $250, and its now swelled to around $800 after I changed my mind and swapped out various parts before buying most of it. The MSI board just kept drawing me back to it, even with its $100 premium. That amp card is just too sweet to pass up.

Plans are to buy the OCZ Modstream 400 modular to replace the Antec unit. I'd much prefer the modular Silverstone unit with shorty cables, but that in turn would run me $100 as well. :(
