Having looked at the physical specification of that motherboad, l can say it takes fairly every modern Power Surply. There is a shop in Eastgate Mall which sells computer parts.
Rather than phoning them and giving them specifications, l would say take your motherboard there and see if there is anything which can fit your needs. lm saying this because l was there at one point, their techguru asked me if he can help and l said yes please!
l asked him the difference in design between lntel quadcore processor and AMD quadcore processor, l just thanked him before he finished his long answer and left.
