How's this Antec PSU

[Ed_Strong]

I'm not in tune with PSU specs so I'm just trying to be ready for IF a sale like this comes up again.
Antec NEO ECO 520C 520W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC PSU

Price seemed right for my low budget, it was on sale at newegg for $49.99 on a 24 hour sale and it made me think of upgrading my current low specs one. I would like to throw a 5770 or 4870 GPU and a TV Card to my current build down the road.

I'm not an overclocker, but the idea of Crossfiring when any of those GPUs mentioned become dirt cheap in the far future is on the back of my head! Is this a good unit? Any Pros or Cons or is there a better option for the money? thanks.

Yes, that is a good PSU for that price. In my opinion Antec has great PSUs, that is actually all I use.

Well...I guess I'm a tad late for a reply. For $50.00 it's a steal! That Antec Neo PSU is made by Seasonic. If you bought it for $50.00, don't look back. It's a winner! Also...40A on a single rail is pretty good too!

I regret I didn't pull the trgger on it, but I didn't get enough replies before the sale was over and then started seeing other good brand PSUs with 46, 48 and 50A for like $10 to $15 more so I didn't know if 40A was still good. I'm not that great when it comes to shopping for a PSU!

Also whats the diff between single and multi rail PSUs?
