GOLD RATED EFFICIENCY
80 Plus certification ensures your power supply isn't wasting power and turning it into excess heat. Under typical load this power supply is 90% efficient or higher.
ECO mode, keeps the fan off when unneeded, and is only ran at the lowest speed needed to keep the internals cool.
While being silent, this entire series has a large single 12volt rail, providing plenty of power to fuel all of your hardware. And lastly, because power without safety is pointless, a full suite of top tier circuit protections to keep you running strong and your hardware safe.
Pros: And that audience is gamers and system enthusiasts who don't have time to put up with sub par components. This is one of the best full featured, fully modular power supplies on the market and is based on Super Flower's amazing Leadex G2 platform. EVGA has included everything but the kitchen sink on this one - including a nylon bag for the supply itself and another nylon case for the extra cables you won't be using. On full loads this supply will handle equivalent to a single GTX 780TI, or dual GTX 760s (which I will be planning on using). Or it will also handle a single R9 290X. This is one of the most solid power supplies on the market that you can buy - everything about this supply is quality and it definitely will not disappoint. EVGA includes everything but the kitchen sink - even a dongle that can be used with PSU testing equipment, though you most likely won't need to use it.
Cons: For the price of this unit it should include a USB connection and software to control all aspects of the PSU, similar to the Corsair AXi series, but power supplies of this quality you can definitely look the other way on it.
Overall Review: The rest of my rig (upgraded from a 4 year old 990FX-based system) : - Fractal Design Define R4 Blackout Edition - EVGA Supernova G2 - Asrock Z97 Extreme 6 - Intel Core i5-4670K - 16GB Corsair XMS3 RAM - Samsung 840 Evo - Western Digital Caviar Blue 1TB - Plextor BD-R Drive - EVGA Geforce GTX 760 Superclocked Edition
