A niche but practical pickup for anyone running a multi-GPU mining rig or a server build that needs to convert 6-pin PCIe connectors to 8-pin without running a rats nest of individual cables. The 17-port board handles the conversion in bulk, which cuts down on cable clutter considerably when you're dealing with a large number of cards. Buy Now at Newegg

Small form-factor pluggable (SFP) transceivers are typically fiber-based, so this RJ45 variant is worth noting if you need to run copper Ethernet over Cat5e into an SFP port on your switch or router without pulling new fiber runs. Buy Now at Newegg

Handy to have if you're installing a graphics card that requires an 8-pin PCIe connector but your power supply only has 6-pin outputs, letting you combine two 6-pin connectors into one 8-pin without replacing the PSU. Buy Now at Newegg

Handy for builds where your PSU cables fall just short of reaching the GPU, or when cable management requires routing power through a tight or awkward path. Buy Now at Newegg
