TOKYO, March 25 (Reuters) - NEC Corp <6701.T> said on Monday it plans to increase the suggested retail price on its personal computers due to rising prices of parts such as DRAM chips and liquid crystal displays. "We are in a situation where we have to jack up PC prices from the next new product line," said a spokesman for NEC, Japan's biggest supplier of personal computers, declining to say how much the increase would be. NEC's comment came after U.S. firm Apple Computer Inc <AAPL.O> last week jacked up the price on its low-end iMac desktop computer by $100, complaining that prices of components were going through the roof. The Nihon Keizai Shimbun reported on Sunday that NEC's peers Fujitsu Ltd <6702.T> and IBM Japan Ltd, a unit of International Business Machines Corp <IBM.N>, also plan to raise their PC prices by 10 to 20 percent starting in April. A Fujitsu spokesman told Reuters: "Although parts prices have been up, we have not decided whether we should raise our PC prices." No one at IBM Japan was available for comment. The newspaper said the weak yen had pushed up procurement costs in Taiwan, where NEC and Fujitsu manufacture and assemble their products. Shares of NEC were down 2.59 percent at 1,130 yen as of 0121 GMT, while Fujitsu was down 3.31 percent at 1,021 yen. The benchmark Nikkei average <.N225> fell 0.48 percent.
