What is power required for HD Native PCI Card?

[akhafaji]

Hi All,
I'm about to change my case and the PSU "power supply" due to the pig nise in my case and a little bit of concern regarding the quality of the current PSU.

My Question : What is required power by the HD native by W?

I'm going to get PSU 850W or 1050W instead of mine "GIGABYTE Superb 720 power supply. http://www.gigabyte.com/products/product-page.aspx?pid=2793#kf"

HDN card is bus powered and requires no direct power connection like a high grade GPU. A PSU around the 650W range is quite adequate for a Core i7.

You don't need a 850 or 1050 watts PSU unless you like to use one or two high-end graphics cards.

I use a 530w high efficiency PSU where my silent graphics card doesn't require extra power.

550 to 650 watts should really be sufficient.

Thank you all for your feedback.

I'M running an 850, though i require a Nvidia 570HD 2.5GB vid card for video editing...

no issues at all.. so far 2x 7200rpm HDDs, two x SSDs soon enough and a hex core i7, currently quad...
