Still going strong since 2008 5/17/2017 11:33:54 AM

Pros: -Reliable
-Lots of airflow
-HEAVY (means good bones)
-LED is cool

Cons: -Cables can be a bit tough to manage but having lots with many options is great for a wide variety of builds

Overall Review: At 80 Plus Bronze and 750 W continuous with a large 60A single 12V rail this PSU is a monster. Efficient, high performance, and still runs after 9 years like the day I bought it. I couldn't ask for a better one.

Ol' reliable! 5/10/2015 6:46:38 PM

Pros: Worked flawlessly for my system since 2012!

Cons: Many many cables, and I have a smaller case, so cable management is atrocious.

Works Great 7/21/2014 3:54:32 PM

Pros: Haven't had any issues with this power supply yet. Love that it is modular, it runs great, never gets too hot, and I haven't had any issues so far

Cons: Wish there were less cords, but that's not really the power supply's fault

Overall Review: BF bought the 850W version recently to replace a shot power supply and it works like a charm as well. Also, it comes with a nice velcro wrapper for the body cords and several black zip ties. Nice touch.
