290x + PSU question

[horse]

I just scored a brand new sealed 290x Lightning for $307.00 otd from Ebay, which mesans I'm the happiest boy in the world (and most anxious), but have some concerns about my current PSU. I'm using a PCP&C Silencer MKIII 600W. Something tells me it may not be adequate enough. Do I need to be looking for a new 700-750W psu, and if so any recommendations?

It looks like your PSU has one big 46A 12v rail, which should be more than enough..even for the Lightning so i definitely think you should plug it in and see how it goes.

If for some reason you do need more power, i would heartily recommend this Seasonic 750w unit. If you don't have that much cash to blow, this Corsair CXM 750w unit is $70 bucks after MIR. Here's another Seasonic 750w unit for $99

Yep, good to go.
Your PSU can handle any single GPU card you throw at it.

According to Anand's Bench a 290X in Uber mode will draw about 400 watts from the wall at full load. A quality 600 like yours (its a Seasonic built unit) will be plenty capable to handle it.

Would a Corsair GS600 be able to handle the 290X?

I was reading a bit earlier, apparently it has LEDs to show your power status. Red= not enough power, blue= good to go, and orange= extra power for more OC. How fricken cool is that!? I kinda figured I'd be all set, just wanted to make sure.

Always a good policy to ask first if in doubt.

The GS600 has a single 48A 12v rail, so you also should be good to go.

your current ps has been checked out to provide 712 watts max.....but keep in mind your ps has two 26 amp rails.......i think it would do fine with any 290x made to date
edit actually it combines 12a and 12b into one rail so it actually a single rails...my bad (even better)

check you rails with a cheap multi meter when pushing your system like with bonic or kombuster if your really concerned
