At the rear of the unit you'll find a three pin power socket that accepts a standard kettle lead. It's worth noting that the power supply inside my Japanese PS3 is most definitely multi-voltage and is happy with current ranging from 100v up to 240v. I was somewhat nervous about plugging it straight into the mains without a voltage step down unit, but after much finger crossing and breath holding my PS3 didn't blow up and just dutifully went into standby mode when I flicked the hard power switch.
There's also a plethora of connectivity at the rear. The familiar PlayStation AV out is present for analogue connection to your TV, while an optical S/PDIF port will let you pump digital audio to your surround sound system. There's also an Ethernet port for hooking the PS3 up to your home network, and if you've really pushed the boat out with your network installation you'll be able to take advantage of Gigabit speeds. But the jewel in the crown of the PlayStation 3's connectivity is the HDMI port. Unlike any other games console currently available, the PS3 can connect to your high definition TV via a digital interface, assuring the best possible picture quality. The PS3 is also one of the first devices on the market to sport an HDMI 1.3 port, which means that you'll be able to take advantage of features like Deep Colour for colour depths up to 48-bit and a wider gamut, assuming that you have a compatible screen of course. HDMI 1.3 also allows the full implementation of the new lossless audio CODECs like Dolby TrueHD and DTS-HD Master Audio.
With all that high-end connectivity on offer, you're going to be pretty disappointed when you open up the box and find that Sony is only bundling a composite video cable with the machine! So, not only are you not getting an HDMI cable to get the best possible output, you're not even getting a component video cable for analogue HD output. OK, so the Wii only ships with a composite cable, but the Wii isn't a high definition powerhouse, and it's worth remembering that Microsoft ships a component video cable with the Xbox 360. So, you're going to have to factor in the cost of a high definition cable when if you're thinking of buying a PS3.
