The M12II EVO 520W power supply is a mid-range unit in terms of wattage and efficiency, but with high-end Seasonic manufacturing quality and fully modular cabling. It is ideally suited to systems with a single CPU and video card (or onboard graphics), and without a large number hard drives.
Jon Bach (President) Says:
We have a long happy history with Seasonic power supplies, and they're the best out there. I really like that even though this is an inexpensive power supply, it still has very quiet operation, and fully modular cables. The modular cables make the inside of your PC cleaner, since we since don't install cables we don't need (we still pass them along in the box in case you need them in the future). It also means that if you have a problem with the power supply and have to swap it out, you don't have to rewire the entire PC -- you just unplug the cables, swap the unit, and plug back in the cables.

I've really come to appreciate fully modular power supplies in the last couple of years, and am pleased that even affordable models in our line like this now have that feature. This PSU is also fairly quiet and offers enough wattage for most single-GPU systems.

I'm so happy to get this power supply on our line! It's actually a lower wattage than the 650W Antec TruePower it replaces in our line, but it still provides more than enough power for the vast majority of systems. The fully modular power connectors is my favorite feature of this unit, as it makes these cleaner looking when installed and much easier to replace, if needed. Added to that, while the Antec units were pretty reliable, our Seasonics have been even moreso, which means we're less likely to even need replacement on these.
