Title: Gigabyte GA-990FXA-UD5 Motherboard Post by: noogai93 on July 31, 2011, 05:49:19 AM I have a Gigabyte GA-990FXA-UD5 Motherboard and when fully populated it has 3 PCI Express 8x slots, 2 x4 slots and 1 x1 slot.
I was wondering if i would be able to fully populate this board with 6 cards with extenders ? I have a Strider 1500w powering it, I'm just not sure if the motherboard will handle it.

I'd go for extenders with molex power for at least two of the cards however; 6 cards would be pulling ~450W through the motherboard, better to let the PSU supply that directly.

That's 1200W for the cards max, plus whatever power for your base system. I think 1500W should do fine, but I don't know much about the particular PSU. In reality I'd expect that system to come out ~950-1000W.

They should be around 180 watt if I recall correctly. Title: Re: Gigabyte GA-990FXA-UD5 Motherboard Post by: goemon888 on July 31, 2011, 06:34:47 PM http://www.guru3d.com/article/radeon-5830-review/2
5830 - 175 5850 - 151 5870 - 188 but not reference 5850 tdp may go upper, Sapphire Extreme is 180w Title: Re: Gigabyte GA-990FXA-UD5 Motherboard Post by: ManOfKnight on August 03, 2011, 09:33:45 PM That is overkill of a power supply
I would also guess that you are looking at a system drawing somewhere around 900-1000w before overclock. Overclocking will jump you to about 1200w if you push the cards hard.
