Stargate Posted September 22, 2020 Share #1 Posted September 22, 2020 Hi. I have a built with an Asrock Q1900-itx with 4Gb Ram and a 2TB WD Red drive. I know it is a very efficient mobo. I'm not trying to be stingy on consumption. The point is that my psu is somehow old and I may replace it, so I don't know if I should go for a regular psu or a pico psu. My current built with my old psu consumes 19w on idle (no hibernation because of plex). Those having the same mobo could you, please, post your consumption on psu or pico psu? Please, indicate how many drives you have and if they are 2.5 or 3.5w. Thank you very much. Quote Link to comment Share on other sites More sharing options...

Stargate Posted September 22, 2020 Author Share #4 Posted September 22, 2020 (edited) That's surprising. A friend of mine has just built his xpenology with an Asrock J3455-itx 4Gb and 1x2TB WD blue 2.5" and he reported 9w by using a pico psu. I don't know if there are any differences between your M mobo version and my friend's itx. Are you using a standard psu or a pico psu? Could I know what bootloader and Dsm version you are using?. He had some trouble with newer dsm versions, so he finally installed 1.03b on 916+ with dsm 6.1.7.

flyride Posted September 22, 2020 Share #5 Posted September 22, 2020 One should to calculate startup power for ps sizing. So that 22w number SHOULD be the mobo power plus the max power for each drive. Running power is going to be less. Quote Link to comment Share on other sites More sharing options...

Stargate Posted September 22, 2020 Author Share #7 Posted September 22, 2020 We tried Jun's 1.04b 918+ but it was unstable. It took a long time to boot and shutdown, and it wasn't detected in Lan. Other users reported problems with asrock j3455 and the latest dsm versions. What dsm version did you install in your Asrock j3455 itx?

Stargate Posted September 22, 2020 Author Share #8 Posted September 22, 2020 Of course. I had already considered it. Thanks. I was thinking about changing the power source and I considered to use a pico psu. Quote Link to comment Share on other sites More sharing options...

What dsm version did you install in your Asrock j3455 itx? DSM version prior update: DSM 6.2.1-23824 Update 6 = both systems. I use the smaller config as a test system for upgrades etc. Yes, boot time and time to network access was almost 20 minutes on larger system Quote Link to comment Share on other sites More sharing options...
