The Tom's Hardware PSU Tier List 2.0 thread is a little outdated... Actually a lot outdated. However, it still gives users a general idea of which brands are higher and lower quality.
For a GTX 950 and a single CPU, I would recommend
one of these.
OP, any power supply that can be had for $25 will be such low quality that it will probably damage your internals within a month or two. The power supply is what supplies power to the internals, and it's important that this power is steady and stable. If voltages are too high or too low, or they vary during use, then your components are likely suffering damage from the voltage input.
My brother had an incident where his hard drive failed. He only had one backup. He put that backup in the machine and that drive then failed. So I took a multimeter to the power supply to find that it was putting out almost 19V on the 12V connectors. Basically, his power supply killed two hard drives and caused him to lose all of his data, even though he had it backed up.
Please consider a higher quality power supply.
