Hi guys,
I'm planning to up grade my Sapphire HD7970 to a Sapphire R9 290 Tri-x. Would the Cooler master Ex2 725 power supply be sufficient as a PSU?
Appreciate any advise =)
Yes, it is more than enough. The Sapphire R9 Tri should only consume 300W peak. You can get by with a much smaller PSU, such as a 500W one or possibly even one of the <450W ones
recently reviewed. As long as it's only one graphics card, 500W will be more than enough.
