JohnnyWong Posted August 15, 2008 Share Posted August 15, 2008 Dear Sir and Guys here, this is my first post, i would like some help regarding my psu. i have upgraded my display card from 2900XT to 4870x2, but after i installed the card, turn on the power i got no display at all (blank screen) my PSU now is Akasa model: AK-P650FF BK 650watt PSU and the rails is as follow; +3.3v = 33a +5v = 24a +12v1 = 13a +12v2 = 18a +12v3 = 16a +12v4 = 8a i want to know whether this PSU can't handle the 4870x2? cause i heard 4870x2 need 40a for 12v rail alone. thanks and looking forward for anyone can give some advice.
