Im building up a silent ITX server and having a little trouble on the PSU front. My Server specs: 986LCD-M/mITX Motherboard 2x DDR2 2GB sticks T5600 Intel Core 2 Duo CPU Mobile (35W TDP) 2x 320GB 2.5" 5400rpm SATA HDDs Just as a reference my HTPC is the following: Zotac 9300-ITX Motherboard 2x DDR2 2GB sticks E6400 Intel Core 2 Duo (65W TDP) 1x 120GB 2.5" SATA HDD 2x 80mm fans My power brick is a 12v 12.5a (150w) which works perfectly with my HTPC and my picoPSU 150w, can use the pc under 100% load and very stable Now I bought a cheapo 120w DC-DC board (http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170579235384&ssPageName=STRK:MEWNX:IT) thinking this should be more than sufficient to power my server given that its a lower spec than the HTPC and has a low power chipset. Clearly I was wrong, it powers on for half a second and then fails. If I put the picoPSU on the server board, all works 100%. Am I being right in thinking that 120w should be more than sufficent to power this server, (power meter at mains said 35-40w using picoPSU) and that the power supply sent to me is not supplying enough power?
