HTPC query - Antec ISK300-150 PSU

[SoulsCollective]

Hey folks
Looking at setting up a new SB-based HTPC, and wondering if anyone can contribute here. I've pretty much picked out all of the parts, I've just not had that much experience with low-power builds before and am hoping I can get some input on whether the case PSU will be sufficient.

• CPU: i3 2100T
• Mobo: AsRock H67-M (WiFi edition)
• RAM: 2*2GB G.Skill DDR3-1600 Eco edition (1.3V)
• SSD: OCZ Vertex 2
• HDD: WD Scorpio Blue 1TB
• ODD: Sony slimline BluRay drive
• Sound: Auzentech X-Fi Forte
• Case: Antec ISK300-150

I'll be using the GPU in the i3 2100T, running Win7 x64 and using the onboard WiFi. I'm thinking that all of this will run about 100-120W, with about 80W of 12V draw, but as I can't find any specs on the PSU that comes with the case beyond the total wattage I'm hoping either someone will know specifics or can provide more general feedback on the above.

way over estimation of power draw. my i7 2600k with discrete HD5670 pulls 100w when gaming. i would say you'll max out around 60w from the wall. are you going for the slower 2100T because it offers lower power consumption/heat? if that's the case, just get a regular i3 2100 and undervolt it to around 1.05v, and it will have the same power draw as the 2100T, except it'll run faster clocks. you can always undervolt the 2100 to consume less power, but you can't overclock a 2100T to have the same speed as the 2100. i believe that mini-ITX board you're getting does support undervolting

edit: and also save a few bucks and downgrade your memory. anything marketed as "Eco" is pretty BS because memory does not draw a lot of power. i already tested this, and the difference between my gskill 2x2gb 1600mhz 1.65v and my gskill 1x4gb 1600mhz 1.25v was not even 1 watt during idle and load. and also just get 1333mhz memory. the max bandwidth on H61/H67 boards is only 1333mhz, and you can't overclock it any higher. if you get those 1600mhz sets, they'll just downclock

Thanks for the input

Was going with the 2100T both for lower power consumption but also lower heat output and therefore quieter operation - from all the reviews I've seen it's more than capable of 1080P BluRay playback, which is all I need it to do, so excess power really isn't a concern.

Edit re your edit: Thanks again :P Remember I'm in Australia, so component availability isn't the greatest - as for the RAM, remember from your example you're actually using twice the number of sticks, so even though the power draw of the 1.25V stuff is lower you're using twice as much
