Where should I go for purchasing computer components especially graphic cards at wholesale price.
You can go to Tianhe Ganding computer Market or the Patific Computer Market, a lot of computer markets around there
just metro Line 3, get off at Gangding Metro Station . Excit C.
Main electronics wholesale markets are in Shenzhen, huge markets. Guangzhou doesn’t really have much, leftover local small time junky stalls, no need to waste time in Guangzhou.
Huaqiangbei is an area and subdistrict of Futian, Shenzhen, The area's status as a major electronics manufacturing hub, and sprawling electronics marketplaces have earned it (and Shenzhen) occidental nicknames such as "China's Silicon Valley", and the "Silicon Valley of Hardware"
The subdistrict runs from Shennan Road at SEG Plaza near Huaqiang Road Station of the Shenzhen Metro for 1 kilometre (0.62 mi) north to the Pavilion Hotel.
Graphics cards are in high demand at the moment from the BTC mining community in China. Be prepared to pay through the nose.
