The SAMA G650 is frequently recommended in PC building communities as a high-value, 80+ Gold certified, fully modular power supply. It is often highlighted for achieving an 'A-tier' ranking on enthusiast power supply tier lists while maintaining a lower price point than many established competitors.

Pros

Fully modular design for better cable management
80+ Gold efficiency certification

Quiet operation
Better value and quality tiering than common budget alternatives like the Corsair CX650M or Apevia Prestige

Cons

650W capacity may be insufficient for high-end or power-hungry builds

Caveats

Described by some users as 'barely' A-tier, suggesting it may sit at the lower end of the top performance bracket

Best for

You prefer power supplies from brands with longer-standing market presence

Elsewhere, a PSU like the [SAMA G650](https://pcpartpicker.com/product/Hxm2FT) or [Adata XPG Core Reactor II VE](https://pcpartpicker.com/product/yhpQzy) would be cheaper.

PSU: Corsair CX650M → SAMA G650 - The SAMA G650 is a fully modular A tier PSU for the same price as the Corsair, which is a C tier PSU.

A 650 watt power supply isn't enough. Get at least an 850w.

Personally I would look at something like a SAMA G650 or G750. These are some of the cheapest A tier PSUs on the market. Gold tier efficiency, quiet operation, and fully modular.

PSU: Aptevia Prestige 600W → SAMA G650 - $20 more, but you're going from a *maybe* C tier PSU to an (barely) A tier modular PSU.
