The verdict
The Pure Power 12 M is the model the Pure Power 13 M replaced. It's ATX 3.0 rather than 3.1, with the older 12VHPWR graphics card plug, but it's still a good unit. On my list it comes in 550W and 1200W.
Both lab reviews found it quiet and well behaved, with good ripple suppression and a 10-year warranty. Unlike the newer model, the fan never switches off, but Guru3D only heard it above about 75 to 80% load.
I'd buy it if it's cheaper than the Pure Power 13 M at the size you need. If the prices are close, take the newer one.
