Julian Powell 20:32 30 Jan 2017 Locked Hi! I have a silly amateur question. I have inside my pc an ssd, an hdd, dvd drive, an extra USB 3.0 with a 4 pin power supply, and Id like to buy a USB 3.0 PCI Express Card which needs power supply. All the power cables inside the PC have 3 or 4 connectors. Can I double them up? So both SSD and HDD run of one cable. Then I'd have enough connectors for everything. Also how can I check how much power I'm actually using to check I'm not over doing things! The power supply is a PURE POWER L7 | 530W click here thanks. J.
