My PC has been acting rather strange lately (complaining about the CPU fan, not finding the boot drive, all kinds of weird problems), so I decided to do some hardware shuffling. I ordered components for a new server and when this new one is operational, I’m going to use my current server as PC and dismantle the current one.
Although I didn’t have much time and didn’t know when my PC would completely collapse, I had a good idea what it (the new hardware) should be made of, cause a few monthes ago I heard Maarten Damen say he had built a really cool server based on a Intel i3 that was consuming a wattage in the low 20’s. That sounded very reasonable to me, so I started off with an Intel i3 540 and selected the other necessary hardware around it, resulting in the following:
- Intel i3 540 CPU @ 3.06 GHz
- MSI H55-GD65 motherboard
- 16 GB RAM (4 x KVR1066D3N7/4G)
- OCZ Vertex 2 2.5″ 60 GB SSD
- OCZ Vertex 2 3.5″ 240 GB SSD
- Cooler Master Elite 333 case (no PSU)
- Intel Gigabit Adapter
I still had a Seasonic SS12 II 380W PSU on the shelf, so I used that one. No DVD player, no graphics card (needed), cause those would only have a negative impact on power usage. I built in 2 x 120 mm cooling fans, but as I soon found out this was overkill and I disconnected 1 of them.
Looking at my Power Monitor Pro, this setup consumes 28W idle. Not bad. But I think this can be reduced even more, so I bought a PicoPSU 120W power supply kit. I’ll know the results with this PSU in a couple of days.
Of course, when I move my 5 VM’s from the current to this new server power usage will probably increase again, but for now I’m quite pleased with this sub-30W usage. My current server is using 70-75W, so a 50% reduction should be doable!
To be continued.
