Would a Superflower 550w Platinum handle a Inno3d Hynrid 980ti and a 6600k? CPU will likely be overclocked to around 4.4.

Spec sheet for GPU says minimum of 600w. I have a EVGA bronze 600w as a spare but the word "Platinum" makes me think the 50w lower would be better?
 
Efficiency rating has nothing to do with rated power. That said so long as the 550 isn't years old (which I doubt it will be if it is Platinum rated) I would say you would be fine as OC Ti + i5 should only consume max ~450W. How many case fans etc?
 
I've seen similar system running weekly on a CX500w 6600k @4.6 Strix 980ti @1550 4 hdds fans DH15. My metre read max of 385 from wall totally stressed out.
 
Had a older less efficient i7 2700k at 4.4GHz and 980Ti at 1450MHz. Never saw anything over 400w from the wall when gaming with a watt meter. Power requirements are always over hyped to protect the daft people with £18 no brand PSUs blowing up their rig. Wouldn't be surprised if your 6600k used at least 50w less at full load than my sandybridge i7.

PSU's degrade over time buy a decent PSU or risk your PSU blowing & taking expensive components with it like mobo/cpu/gpu!

Nvidia GPU Boost 2.0 dramatically increase how many amps the gpu needs I think a decent 750W modelis good enough but if you also overclock your CPU that is another massive amps drain.

Aim to spend around £140 for up to 800W & £150-200 for up to 1000W (which is also future proof a little amps wise).
 
The psu was only launched last year and it will be more than enough. You have all of the 550w available on the 12v rail and a good 550w psu such as yours is more than enough for just about any single gpu setup. I would say you won't be pulling more than 400-420w total system power at the wall even with the cpu overclocked.

Just ran a few benches (Sleeping dogs extreme / ROTTR) with a 4690K @4.5 (1.25v) / 980Ti and saw no more than 410w peak at the wall.

ED; That's with a SF1200 plat, three SSD's, two HDD's, 4 fans and a couple of D5's fwiw.

It should work ok given the figures stated above, and Supeflower are very good PSU's (I have a 1000W SF Plat in my gaming rig and a 650W SF gold in my work rig - this powers a 780Ti and overclocked 2600k system.)

Having said that, I do like a bit of headroom when it comes to PSU power. If they're pushing it they can get hot and loud and I like as quiet a system as possible. The fans don't even need/ bother to spin up on both my supeflowers.
 
Just installed the 980ti and the rig is pulling 350w when running Firestrike Extreme according to my power meter.

Should have room to push my 6600k a little.
