Gigabyte G1 GTX 980 sli psu requirement......

[Thiva]

does 1000watts psu enough for powering up the two Gigabyte G1 GTX 980 (SLI)..?

Depending on the rest of the system a 750w or 850w unit would be enough. Just make sure to get a quality unit.

You certainly don't need 1,000 watts to power two 980's. 850 watts would be perfect, especially if you're overclocking the GPUs. If you're not overclocking the GPUs then 750 watts will be enough.

but for gigabyte g1 gtx 980 needs 600watts to run according to the requirements in gigabyte website http://www.gigabyte.my/products/product-page.aspx?pid=5208#sp
that means 1200watts need for SLI setup....

600W for an entire system that includes a GTX 980, 980 doesn't chew 600w on itself (it would be scary if it did).

the 600w includes rest of the system like CPU etc, so for dual 980's you certainly don't need to double the wattage.

GPU's never consume as much as the minimum PSU recommendations list. The 600 watt requirement is for the entire system and even then, depending on your system, you won't use that much. For example, I have a GTX 770 that recommends a 600 watt PSU but it only uses 225 watts at maximum load so if I had two in SLI running at maximum load then it would be around 500 watts for two 770's in SLI. Most of the time my GPU will not use 225 watts, maybe never. It could be closer to 200 watts or so.

thanks for the reply.....you were correct.......in guru3d site they said that gigabyte gtx 980 sli required only 800watts or 600 watts...

The wattage often depends on what model you get, some versions of the 980 may consume more watts then others (not by much but some). I would recommend getting a 850 watt PSU just to be safe.
