[NAME]    What would i want to look for to make sure i find a power supply that is compatible? First on hand . . . make sure it will physically fit in the PSU swing-out contraption.  Look for something like:  Dimensions: 140 mm (L) x 150 mm (W) x 86 mm (H) Seasonic Focus 750 watt Fully Modular  Fully modular is best so you only use the cables you need. Make sure the cables include the connectors you need for the components in your rig. (click photo to embiggen) [IMAGE]
Wanting to upgrade my CPU from i5-8400, wasn't sure if the current power supply would be enough to sustain good performance. 
Aurora R7, 460w power supply enough for GTX1070 and i7-8700k?
