With a minimum configuration, it may work with a 350W PSU, but note it does not work with some simple desktop PSU, this is why if someone is getting a third party chassis which is not on the Tested List, Intel advise you to check the board minimum requirement and PSU/front panel connector datasheet to know if the psu is supplying the right voltage to the board.
Usually, some people uses the power budget tool as a reference.
Yes, i agree with you, when someone choose a PSU, they need to know what other components are being used as well as, each component definitely make a big difference.
A simple example can be a high end graphics card which needs an additional Power of at least 75 W.
All the best,
could u confirm i´m on the right track? http://download.intel.com/support/motherboards/server/s3200sh/sb/e14960008_s3210sh_tps_r1_7.pdf
under 8.1 Power Budget -> Table 66. Power Budget:
Requirements – 350W
350W / 22A / 21A / 10A + 16A=26A / 0.8A / 2A
130W / 1Amin / 1Amin / 2Amin / 2Amin / 0Amin / 1Amin
edit: i understand that these are just values for a sample configuration, but is there another location for the board minimum requirements you were talking about?
Indeed i believe that 350W is the minimum recommended. remember that power supplies are only in the range of 60 - 85%ish efficient so a 350W psu with 70% efficiency is only really able to provide 245W.
350 is the minumum and depending on what hardware you have it will need more. (lots of sas drives, many network cards, raid controllers, big CPU, lots of memory etc).
What is the 80 PLUS specification?
The 80 PLUS performance specification requires multi-output power supplies in computers and servers to be 80% or greater energy efficient at 20%, 50% and 100% of rated load with a true power factor of 0.9 or greater. This makes an 80 PLUS certified power supply substantially more efficient than typical power supplies and creates a unique market differentiation opportunity for power supply and computer manufacturers.
everybody agree that running a PSU under 100% load for 24/7 is certainly not healthy, so i will keep some headroom for my needs.
in the end i will use a relatively energy efficient CPU (~30W load), some SSDs and only a few add-in cards. (data is stored external) even under 100% load, a 350W PSU would be sufficient here.
It´s a pity that there is just a sample configuration in the documents - (TPS): 8.1 Power Budget -> Table 66. Power Budget
does anybody know if there are any minimal power requirements from Intel, in contrast to the mentioned chart?
it would be very helpful on the PSU purchase.
edit: in consideration of the following chart: http://www.spec.org/power_ssj2008/results/res2009q1/power_ssj2008-20081215-00106.html
the tested Xeon X3360 / 4GB / 1 HDD and a "FSP FSP220-60LE" - 220W PSU draws about 110W under full load
a similiar configured system with the L3360 and a "HIPRO HP-U3528F1" - 350W PSU draws about 99W under full load
those results differ quite a lot from the charts in the TPS from Intel, so i´m more confused. could anybody (from Intel) clarify this for me and maybe others please?
i will stick with the "Power Supply Output Capabilities", as mentioned in your chart, on my PSU purchase - this is a helpful guidline.
unfortunately the efficiency of the 420W PSU in the Intel Chassis isn´t that competitive (<80%), hence i´m looking for a third party (80PLUS)-PSU which meets my requirements.
