Corsair CX-M Series 650 W @ TechPowerUp
 

The Corsair CX-M Series 650 W is one best available budget PSUs. It performed very well in our tests and runs reasonably quiet. Given the affordable positioning it shouldn't be an issue that it lacks the 12+4 pin PCIe connector for future GPUs, most budget PSUs won't meet the strict ATX 3.0 requirements anyway.
