Will i have enough juice?

[deezy1h]

Hello Tom's Hardware community,

I'm on the process of building my second computer since 2008, and a lot has changed. so I've been researching like a crazy mad man this last week ahaha.

Anyways back to the subject I'm planning on getting this components

-Corsair Obsidian Series 550D [CASE]
-i5 3570k[CPU]
-asRock z77 extreme4[MoBo]
-CORSAIR Vengeance 8GB (2 x 4GB) DDR3
-GeForce GTX 480[GPU]
-1TB 7200 Hard Drive
-120GB SSD
-Antec Kuhler H2O 620 Liquid Cooling System
-SeaSonic M12II 620 Bronze 620W [PSU]

Now my main question is regarding my PSU, Will i have enough Juice for the components above.

I know the recommended psu is 600W for GTX 480, but some websites I have come acrossed say getting a 700W is where i should be so I wont redline/stress my PSU and have it die on me O_O

I do plan on overclocking, but not anytime soon maybe in a year so, when i feel i want a extra boost

Thanks for the Help,
eddie

I looked it up, and sure enough it does say 600W for a minimum recommended PSU. I would follow that advice and get a 650 or 750 W unit.

It's always a good idea to have a little headroom on your PSU. Especially with that power hungry GTX480 and possible OC in the future. If I were you, I'd get a HD7850. It trades blows with the GTX480, and I don't think either has a significant edge over the other. But the the PSU you have selected, which is excellent by the way, will handle the HD7850 with ease. Since the HD8750 is very power efficient it can even support 2 in CF down the line. That possibility and the need to get a more expensive PSU for the GTX480 makes the HD7850 a clear winner in my opinion. Thats why I got it

A system with a single GTX480 requires a 600W PSU with one 75W 6-pin PCIe power connector and one 8-pin PCIe power connector and at least 42A on the 12V rails. The Seasonic M12II-620 has 48A on the 12V rails, sufficient PCIe power connectors, and ample reserve power capacity for OCing the GPU/CPU. If you don't already own the PSU, then the Corsiar TX 650V2 is actually a better deal right now for $70 after MIR; $20 less, 53A on the 12V rail, same warranty and still made by Seasonic. I agree with the above recommendations on a newer generation, more power-efficient GPU instead of the GTX 480.

Thanks for the great advice, I will take into consideration buying a stronger PSU I think there was a 750w Corsair on newegg for around $100 usd.

I'm still going to stick with with the GTX 480 because the following:

1) According to the website posted below the GTX480 out performs the HD7850

2)HD7850 is $250 usd at the moment, while GTX480 is around $210 USD,
3) I'm a Nvidia Fanboy ahaha ^_^

Regardless you're information was solid, thanks again Thomas and Tom's Hardware Community for helping me with my dilemma
