PSU is good enough for graphics card?

Hello everyone, just had a quick question - as part of my first computer build I would like to use a Sapphire Radeon HD 7870 XT 2GB Boost graphics card, along with an AMD FX6350 3.9Ghz CPU (and all the other components).

My concern is about the PSU - I have a Seasonic M12 Bronze 620W supply available. Will that be enough to handle both the GPU (minimum PSU requirement 500W) and CPU (125W usage)? I don't intend to overclock anything (yet), and this will be used for gaming.

Thanks!

Easily.
The reason they list the 500W minimum is to try to cover the lowest common denominator PSU and sometimes that doesn't even cover it.

Your Seasonic PSU is among the top quality supplies out there. You could run two 7870s and the rest of your system on that supply.

Most definitely.
The 7870XT is not a power hog. You could even crossfire with that PSU.

Err, those cards will draw 200w a piece one is perfectly fine but do not try to run two on there.

Look at the power consumptions for 2 7970s in crossfire:

The 7970 has a higher power requirement than the 7870s (stock or XT). In crossfire at full load, 567W is the requirement for 2x7970.

Your PSU can easily handle 2 7870 XTs.

Yep, my 7950's barely touch 500watts.
I don't know what the whole "you need a huge powersupply for anything" stigma is.
