PeterSmiles Posted December 14, 2013 Share Posted December 14, 2013 I have a Thermaltake TR2 RX 550 Watt PSU http://www.thermaltake.com/products-model.aspx?id=c_00001556 It has 2 x 12V rails from each 19A, but has 3 connectors and a pcie connector. My motherboard use 18 Watt in total https://www.asus.com...rboards/E35M1M/ I have 9 Sata disks connected split over 2 connectors, while the 3rd connector feeds the case fans.The only thing else that is connected is a 4 port Sata extension card. 9 Sata disks would mean a maximum power usage of 72 Watt according to the WD spec, but lets assume that at start up spin they use 9 x 20 Watt = 180 Watt Yet my motherboard reports frequently power surges at start up. I'm thinking that the disks are all connected to a single rail, which will provide only 228 Watt ( 19A x 12V ), but I can't figure out which of the connectors use which rail. Someone can help me out with this ? Link to comment Share on other sites More sharing options...

If all harddisks are connected to a single 19Amp rail, there is a small chance I would say, that's why I try to find out how one can be sure that half of them are connected to 1 rail and the other half to the second rail.
