Putting together a new build... 620watt PSU enough?

[GRAFiZ]

Bought some used parts, putting together a new gaming machine.

Asus P8Z77-V Deluxe
Intel 2600K (will be overclocked to 4.4ghz or so)
2x4gb GSKILL Ripjaw 1866
EVGA GTX Titan SC
2x120gb Corsair SSD
1x4gb 7200rpm HD
Cooler Master Seidon 240m
Couple 120mm case fans

I just picked up a brand new Antec HCG-620M 620w PSU. 80plus, SLI ready, modular, blah blah

It's not top of the line, but it's not some no name faker either.

Typically when I put together builds I always overdo power supplies, my other two machines both have 850watt units that are above and beyond what is called for.

Question is, will that PSU, be enough for the build? It's rated for 620watts of continuous power and at load the build should draw far less.

Thanks for the help!

If you plan to heavy oc also your cpu I think 620w won't be enough in full load.
I'd switch that psu with a corsair ax760

620W will be fine for any single GPU setup, even a 250W GPU like GTX Titan. In total you should see about 350W maximum load during gaming. In Guru3D's review, a system with GTX Titan and an overclocked 130W TDP processor consumed 372W from the wall, that's about a 330W load on the PSU. The minimum recommended unit for this card in an average system is 550W, and in an overclocked system, a bit more than that. So I'm confident your 620W unit will handle it just fine, it's a Seasonic build and it performs like one.

Thanks for the replies! Both sides of the spectrum here... many review sites suggest max load with a titan, even with a higher powered cpu doesn't even come close to the max output of this PSU. I will continue to research.

Thanks again!

Nonsense:

That's 544W at the wall socket for an OC'd i7-3970X @ 4.8GHz and Titan @ 902/6608.
