dikkiedirk Posted August 10, 2012 Share Posted August 10, 2012 My X760 PSU comes with 3 modular cables with a total of of 8 SATA power connectors. If i were to obtain some extra cables, how many outputs on the PSU can take such a cable? So how many SATA power connectors can I obtain with regular cables? Link to comment
mikejp Posted August 10, 2012 Share Posted August 10, 2012 Good choice on the Seasonic!! I don't use anything but Seasonic anymore...never had one fail... I don't own the X760, but.... how many outputs on the PSU can take such a cable? My modular ones, (2) X650s & (2) X750s, all have 5 outputs for peripheral connections. how many SATA power connectors can I obtain with regular cables? None of my cables have over 3 SATA connectors... sooo... 15. Hope that helps... YMMV! Link to comment
dikkiedirk Posted August 10, 2012 Author Share Posted August 10, 2012 Thanks. Was afraid of that. Just how to power a 24 disk server then? Without using splitters. Getting drive-cages? Link to comment
DeepSpace Posted August 10, 2012 Share Posted August 10, 2012 Is there a reason you are against using splitters? Link to comment

DeepSpace Posted August 10, 2012 Share Posted August 10, 2012 I don't think you're going to get away from not splitting SATA power. If you went with drive cages or a backpane setup (Norco 4224) you could tidy cables by making them yourself, but you're still splitting the power out. Power != Analog Signals, as long as your wire gauge is thick enough 18awg or lower, you're not losing anything (like reliability) by splitting it. Link to comment
Frank1940 Posted August 10, 2012 Share Posted August 10, 2012 It's disrupting my cabling "tidyness" and overall reliability So cut off the connecting connectors on both the splitter cable and the power cable. Solder the wires together and use heat shrink tubing on the solder joints. Solves both the reliability problem and the tidyness issue. Link to comment
downloadski Posted August 10, 2012 Share Posted August 10, 2012 I ordered a X-660 and have the same issue. Intended a 20 or 24 hdd setup. I searched a bit and found http://www.moddiy.com/products/Antec-Modular-PSU-Single-Sleeved-5-x-SATA-Integrated-Cable.html This way 5 connections times 5 cables is 25.. My hdd's Deskstar 7K4000: startup: 1.2 (+5V) & 1.5 (+12V) (amps) = 14,4 Watt (5V) / 18 watt (12V) idle: 6.9 Watt Deskstar HDT721010SLA360: startup: 0.5 (+5V), 2.0 (+12V) = 6 Watt (5V) / 24 Watt (12V) idle: 5.2 watt Samsung HD154UI: startup: 2.0 A = 24 Watt idle: 5.1 Watt Seagate ST2000DL003: Startup: 2.1 A = 25.2 Watt idle: 4.5 Watt Lets say 5 of each: Deskstar 7K4000: 7.5 A = 90 Watt Deskstar HDT721010SLA360 10 A = 120 Watt Samsung HD154UI: 10 A = 120 Watt Seagate ST2000DL003: 10.5 A = 126 Watt Some cable specs (no idea if this is correct info) http://www.playtool.com/pages/psuconnectors/connectors.html That has 2 tables: Connector part numbers Cable connector Terminals Maximum current per circuit Molex 67582-0000 Molex 67581-0000 1.5 amps Official cable/connector maximum wattage delivery Voltage rail Number of lines Maximum current Maximum wattage +3.3 volts 3 4.5 amps 14.85 watts +5 volts 3 4.5 amps 22.5 watts +12 volts 3 4.5 amps 54 watts I assume the 1.5 amps is per line in the connector, and there are 3 * 3.3v, 3 * 5 v and 3 * 12 v lines in a sata power connector. It does not seem wise to split 1 sata power into 3, 4 or 5 other sata power, than you could overload the originating connector. With the 6 pin to 5 SATA power (the link above) over AWG 18 wire, the wire seems to be the limit, as each drive take only what it needs via the connector from the wire. Hard for me to understand the specs for AWG wire, but here is a table: http://www.powerstream.com/Wire_Size.htm With google i find 6 - 9 Amp for longer runs. But also 16-20 Amp so i am lost here. 9 Amp would be not enough for 5 times a average drive.. Any comments ? Link to comment
downloadski Posted August 10, 2012 Share Posted August 10, 2012 IF you want splitters, perhaps something like this: http://www.moddiy.com/products/SATA-Power-Y-Splitter-Cable-%28Black-Sleeving%29.html Than you split 1 into 2. 2 of these and a 3 connector standard cable becomes a 5 connector cable. I find the locking quality of the sata power connector not too good.. Link to comment
downloadski Posted August 11, 2012 Share Posted August 11, 2012 I did send a e-mail to that company which makes these cables (the links in my posts) I got an answer in 30 minutes (my evening is their very early morning i think) They will make this cable to your specifications for that price. So you have to tell them the powersupply you use, and the space between the connectors if different than 30 mm. You can also get it in the colour you want. Link to comment
