The Litepower 450W uses a standard 20+4 ATX connector giving the end user the option of installing it on an older 20pin system or the standard 24pin motherboards in use in the last several years. There is no latch or clasp to hold the extra 4pin connector onto the primary however there are two tabs that should prevent it from working out of the motherboard socket when the main section is clipped in place. A 4pin connector provides the additional +12v power needed for the CPU. Many motherboards today have the option of using an 8pin EPS style of connector which effectively doubles the amount of current that the auxiliary +12v can provide, however this is not an option with the Litepower 450W.
A single 6pin PCIe cable is supplied for powering many of today's mid-range video cards. This is sufficient for something along the lines of an nVidia 9800GTX+ or ATI HD 4850, but anything higher will likely require more power than the Litepower 450W can potentially provide. Surprisingly a total of four SATA connectors are supplied, which should be plenty even for those with multi-drive RAID arrays, although having two separate cables would be more useful, and possibly necessary, for those with SATA optical drives as well. Five standard Molex and a single floppy connector make up the last two cables.
Next let's look at installation and testing.
