Available in late October 2004, it is smaller, thinner, and quieter than the older versions and includes a built-in Ethernet port (in some markets it also has an integrated modem).

Due to its thinner profile, it does not have the 3.5" expansion bay and therefore does not support an internal hard disk drive.

In early 2005, it was found that some slimline power transformers manufactured between August and December 2004 were defective and could overheat.

[citation needed] An add-on to add HDD support to the newer 7500x and onward models called the HDPro was created but had limited success.

[citation needed] On July 19, 2007, Sony started shipping a revision of the slimline PlayStation 2 (SCPH-7900x) featuring a reduced weight of 600 grams compared to 900 g of the SCPH-7700x, achieved through a reduction in parts.

The AC adaptor's weight was reduced to 250 g from the previous 350 g.[7] Another refinement of the slimline PlayStation 2 (SCPH-9000x) was released in Japan on November 22, 2007.

[8] As well as some cosmetic changes, the design of the hardware was overhauled, incorporating the power supply into the console itself like the original (fat) PlayStation 2 revisions; this also increases the total weight to 720 grams (25 oz).

On SCPH-9000x series consoles manufactured after the third quarter of 2008 as the last revision of the PlayStation 2, some changes were made (indicated by date code 8C) to incorporate a revised BIOS, which disables an exploit present in all older models that allowed homebrew applications to be launched from a memory card.

[citation needed] The slimline model was initially released in black, however a silver edition was made available in the United Kingdom, Germany, Australia, United Arab Emirates and other GCC countries, France, Italy, South Africa, and North America.

Sony also manufactured a consumer device called the PSX that can be used as a digital video recorder and DVD burner in addition to playing PS2 games.

Released in 2009, the Audiovox VOD10PS2 was an officially-licensed aftermarket overhead DVD player for automobiles that included a built-in PlayStation 2.
