Cooler Master eXtreme Power Plus 600W vs Antec NEO ECO 620C

I'm looking to buy a new PSU, and I considering one of those two:

1) eXtreme Power Plus 600W

2) Antec NEO ECO 620C

They both seem like decent products, but the Antec is 20W more (will it make a difference?) and it boats 80% "efficiency" (as opposed to 70% for Cooler Master). But I never tried Antec before while Cooler Master is highly recommended as a brand.

So, any thoughts?

That Antec is actually a rebranded SeaSonic S12II 620 Bronze 620W ATX12V V2.3 / EPS 12V V2.91 80 PLUS BRONZE Certified Active PFC Power Supply. Seasonic makes good stuff so it should be ok. However for some reason I see people reviewing that the Antec version outputs less than 5V on the 5V line. I doubt it will be an issue but I'm not sure why it's doing that and nobody who bought the original Seasonic edition complained. I am wondering if Antec requested a cheaper edition that does not come with the high quality Japanese capacitors, they had to cut costs somehow. It also does not come with a new power cable.

My recommendation would be the Cooler Master, despite lacking the 80plus certification. However if you could muster up another 10 bucks you could try to get the COOLER MASTER GX Series RS650-ACAAE3-US 650W ATX12V v2.31 80 PLUS Certified Active PFC Power Supply. That is the best bang for the buck in every way. You could also try the 550W edition, trust me 550W will more than power any system with 1 high powered GPU.

Additionally don't worry about things like extra 20W, sometimes those figures are just marketing. What you should note is how much more specs Cooler Master gives you on their site. You can clearly see the load curve for the Cooler Master I suggested, as opposed to Antec. Antec likes to hide specs and I could never trust them.

I personally bought this PSU recently for an i7 Build and I couldn't be happier:

That being said the Cooler Master GX 650 mentioned above is only a So/So PSU as far as I have read.

And the Extreme Power plus 600 looks even worse:

The Antec (Seasonic) on the other hand seems to be a Very nice PSU:

Unfortunately I can't afford the GX series, it's too expensive here. And I haven't found the 550W edition.

I'm leaning toward the Antec since the eXtreme Power 600W has disappointing reviews (seems most agree that it's more like 360~450W unlike advertised).

Anyways, I'm not in a hurry, I still need to sell my HEC Raptor first.
