The verdict
This is my top Tier C pick: Gold, fully modular and ATX 3.1, with a 10-year warranty, at a budget price.
HWBusters is the only lab to test the V2 so far. It found Platinum-level efficiency at 115V, tight 12V regulation and a native 600W graphics card cable, but a fan that gets loud at higher loads and overall performance that trails pricier rivals. It also lacks fan failure protection.
The model matters. HWBusters says its strongest argument is the price, provided you get the V2, so check the listing carefully.
