The second seed, who is hoping to become the first player to successfully defend the title, had to overcome fatigue and leg cramps to reach the last eight.
First Hsieh, who ranks world number 23, started her day by beating Kurumi Nara of Japan 6-7 (5-7) 6-3 6-4 in the first round match held over from Wednesday due to rain.
The Taiwan ace was leading 4-3 when the match was halted and she took another two hours to complete her victory, as well as needing two medical times.
Hsieh was then back on court three and a half hours later to face Zhang Shuai of China and she was energised by her break, romping past Zhang 6-3 6-3 in 73 minutes.
The 27-year-old will now face American wildcard entry Bethanie Mattek-Sands, who stormed into the quarter-finals with a 6-1 6-4 victory over Duan Ying-Ying of China.
Mattek-Sands, who won the doubles title at the Dubai Duty Free Tennis Championships last weekend with India's Sania Mirza, said: "I've never won any singles title before, even though I have reached a few finals.
"Maybe that first win will come in Malaysia."
Others who have qualified for the quarter-finals are Japanese fourth seed Ayumi Morita, Karolina Pliskova of the Czech Republic, Australia's Ashleigh Barty, Thailand's Luksika Kumkhum and third seed Anastasia Pavlyuchenko of Russia.
