brisimmons105 Posted December 4, 2019 Share Posted December 4, 2019 I purchased a new power supply a few years back that came with 6 SATA power cables, which are now used up. I want to add a few new drives, so I was wondering what the best way to do that would be. I have 3 molex cables from the power supply that I can get a SATA connector for, or should I buy a splitter for the SATA cables and extend them that way? The PS is 500 Watts which should have no issues handling the load, I'm just out of cables. Thanks! Quote Link to comment
testdasi Posted December 4, 2019 Share Posted December 4, 2019 If powering 3.5" HDD then I would use the MOLEX -> SATA since I don't want to overdraw current on a single SATA cable (which can happen if multiple HDD spins up simultaneously). If powering 2.5" SSD then it doesn't quite matter due to relatively low power draw of SSD but I would still use MOLEX -> SATA just to be safe. The quality of the cable, in contrast, is a bigger concern. Dollar-store stuff is highly not recommended. Quote Link to comment
brisimmons105 Posted December 4, 2019 Author Share Posted December 4, 2019 Thanks testdasi. They are 3.5" HDD. Any particular brands for the MOLEX to SATA? Quote Link to comment
