Whatsa good PSU to replace my Thermaltake TPG-1050W

I have a Thermaltake Toughpower Grand TPG-1050M 1050W PSU and I want to replace it because the fan on it is making noise and I want to replace it now before very bad things happen and I was wondering whats a good, affordable PSU to replace it with? I was on Tom's Hardware and they recommended the Seasonic M12II 620W, I haven't bought it yet though as I wanted a second opinion.

I have a Asus Crosshair V Formula motherboard, a Sapphire Toxic Radeon HD 6950, a Phenom 2 x6 1100T black edition CPU @ 3.3 GHz, 16 GB of DDR3 Corsair Vengeance RAM, 3 7200 RPM HDDs, Creative Soundblaster X-Fi Titanium Fatality Champion soundcard. I just want a PSU that will be stable, keep all my stuff powered, and not give me grief as the Thermaltake one has. I'll RMA the Thermaltake one next month so the one I get now will be my backup.

 

Is there a reason you went with a 1050 watt PSU?

Anyway, I'm partial to Seasonic PSUs.

This is the one I own: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151105

This might be decent for you: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151118

I prefer near top of the line, since the PSU is also a critical device to have on a PC.

I eventually plan to have 4 video cards, hence the reason for what I have.

 

I went with 1050 watt because I originally planned on my current system to be crossfired with two GPUs and I did some calculations and it was closest to what I thought I needed. However I have long since taken the second 6950 out. Too much aggrevation for such little pay off.
