Enough power for gtx570?

Seasonic is a good brand you should be fine. I'd be more worried if it were a cheaper brand.

Are you putting in the system in your sig?

I think it should be fine, but I would be careful about overclocking though.

No, i will use a sandy bridge 2600k, that will prolly end overclocked to ~4.5ghz at least.
 
The S12 will run it fine - it comes with 2 6pin PCI-e connectors, which happens to be the amount needed for the 570.
 
I'm not the most educated psu person, but knowing what the 570 requires and what your psu brings to the table, it seems like you would be pushing that psu pretty hard running the 570 with the rest of that build.

This. With an overclocked SB setup I would look at maybe a 600~700w
 
Sandy Bridge chips are much more power efficient then the chips they replace.
Bit-tech
i7-2600k (SB) SYSTEM @ 4.83Ghz = 234w
i7-950 SYSTEM @ 4.3Ghz = 383w

2600k (SB) SYSTEM @ stock = 153w
950 SYSTEM @ stock = 233w

Remember, these are power readings for the WHOLE system. Actual chip consumption is lower. Here is the full list of system specs.

* ATI Radeon HD 5870 graphics card (Catalyst 10.11 WHQL)
* 2TB Western Digital Caviar Black hard disk
* PC Power & Cooling Silncer 750W PSU
* Asus P8P67 Intel LGA1155 motherboard
* Asus P6TD Deluxe Intel LGA1366 motherboard
* Asus Crosshair IV Formula AMD Socket AM3 motherboard
* Gigabyte GA-H55M-UD2H Intel LGA1156 motherboard
* 4/6GB (3 x 2GB) Corsair 1,600MHz DDR3 memory (CL9)
* Titan Fenrir TTC-NK85TZ CPU cooler, except for LGA1155 systems where we use a Corsair H50 due to the incompability between the Fenrir and Asus P8P67 motherboard



If you factor in a GTX570 at 100% load (CPU @ 100% load), then you're looking at total system consumption of around 450w-480w, depending on how many hard drives, fans, burners, etc. 100% total load scenarios simply don't happen in the real world, so your actual power draw ceiling will probably be 400w, with a few special cases (folding being the primary one). So to answer your question...yes, a 500w Seasonic will probably do it. Its actually close enough that I would go ahead and try it anyways. The S12 has a full set of overload protections, so if it cuts off...upgrade. Honestly, I don't think it will...not unless you're a munchkin and crank open IBT + Furmark then take a nap...

But if you are looking to upgrade, then a quality 550w+ unit would fit the bill nicely. If you plan on adding a second GTX570 in the future for SLI, then look for something in the 650-750w range.

FYI The S12-II offers about 408W on 12v apparently. Which 500w Seasonic PSU have you got?

600-700W is way overkill for a single-GPU system, even with an overclocked CPU and GPU. 500W is plenty.

He linked to a picture of his PSU label in the OP. It has 38A available on the +12V rail, which is equivalent to 456W.
