My favorite is the one I own - the X-560. Fully modular, powers my GTX 670 and Phenom II X4 980 with ease, is compact and quiet (the fan doesn't spin until its needed). Best power supply I've ever owned.
I have built a large number of PC's that used their X-660 PSU because it is so reliable. Seasonic is among a very very few PSU's that I would trust in any machine I build.
As for why I would like to win? Well my wifes and my current rig both have aging Enermax Liberty 620's in them. They are both at least 6 years old at this point and I feel they have more than paid for themselves. It is time to step up to the next level as I can't do any further upgrades until I replace those. Getting a new Seasonic would be huge for me.
SeaSonic- I have been building Gaming PCs for people for years, using Power Supplies made by SeaSonic. Face it, you have too, as they make PS for Antec and Corsair also. These PS are of the highest quality, longest warranty, and some of the quietest Power Supplies on the market. I have always picked power supplies with a 5 year warranty and these are the ones that SeaSonic builds. Their own brand has even better warranties, with models ranging from 5 to 7 years. If you don't need an upgrade after 7 years, then you don't really need a PC. Buy SeaSonic, or stay at home dog.....
Favourite Seasonic product? My X760. It's been a year and I've yet to hear the fan from it. The same can be said for my X660. Aside from that, that gold colour scheme is just gorgeous to look at every time.
My current psu is the SeaSonic M12II 520 Bronze 520W ATX12V v2.3 / EPS 12V v2.91 SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply. My powersupply cables are tidy. This power supply is quiet and trouble free. What more could one ask for?
I am the proud owner of a SeaSonic M12II 620W 80 Plus Bronze certified power supply. In two years time I've owned it, it hasn't let me down. I live well outside the city and the power grid here is terrible. Line voltage sags in the summer, transients, etc. The SeaSonic keeps right on chugging along. I highly recommend SeaSonic for its high quality, stability, reliability, and attention to detail.
I considered making up some bullshit story about the greatness of a Seasonic product that I've never owned just to be considered in the drawing but, truth is, I've never used their gear. Maybe it's good, maybe not. I dunno. I'd give it a shot if I won one though.
I had a M12D 850watt PSU that I bought 4 years ago back in 2009,
I Live in North Carolina, and we have quite a few Storms here annually, needlessly to say, a Big Lightning Storm came through My area back in early September of 2010,
I wasmt ho,e at the time (at the hospital with wife giving birth to twin Daughters yippe!!!)
and when we came home the next day, it seems a Lightning Bolt hit my home and fried my TV, Refrigerator , Microwave, Stero system (nnnnooooo!!!!) and my Gaming Rig (why me)
well after the insurance company helped me with replacing some items,(week later)
I took apart my rig and found that my 9800gt,my ddr ram,my Duo core and mobo were all fried except for one Component............that's right u guessed it, the Seasonic M12D was still working..............LOL!
I used it in another rig that my neighbor gave me, for a year until I gave it to my nephew.
anyways im trying to build a rig , surely but slowly (kids are expensive )
what I wouldn't give (except wife and kids) to have another Seasonic PSU/Gaming Rig
2 Great things Happened that year /month, 2 baby twins, and my Seasonic M12d Survived a Big Lightnong Storm.........
