I recently got a new video card for my vaio vgc-ra710g which meant that i had to get a new power supply. i went out and bought thermaltake purepower 430w. it is missing a 3-pin plug and when i turn my computer on it says power fan abnormal. i've tried getting 4pin-3pin adapters but it still does not work. what can i do?
