When we want to choose the best power supply for our equipment, there are many factors that we must take into account, far beyond simply the maximum power or its efficiency certification. Today we are going to carry out a technical comparison of the Corsair CV650 vs TX650M power supplies to see if the price difference between the two is worth it, or if on the contrary we can save good money by acquiring the cheapest and with full guarantee.
Both power supplies have the same power and have a similar number of connectors, but under the hood they are quite different. And, in the same way, their prices are different because without taking into account possible and potential offers, the CV650 is substantially cheaper than the TX650M, which is why today we are going to ask ourselves whether or not it is worth paying the price difference between both.
As we can see there is a price difference of almost 30 euros between both power supplies, and that they have the same power. Why is this so? Is it worth buying the most expensive model? Let’s check it with a technical comparison.
Corsair CV650 vs TX650M technical comparison
| Corsair CV650 | Corsair TX650M | |
|---|---|---|
| Power | 650 W | 650 W |
| Efficiency certification | 80 Plus Bronze | 80 Plus Gold |
| ATX12V version | 2.52 | 2.92 |
| Fan | 120mm Rifle Bearing | 135mm Rifle Bearing |
| Zero RPM mode | No | No |
| Dimensions | 150mm x 86mm x 140mm | 150mm x 86mm x 140mm |
| Modular | No | Semi modular |
| Wiring type | Standard thicknesses | Thick ATX and EPS, Flat Rest, Black |
| Warranty | 5 years | 5 years |
| ATX 20 + 4-pin connectors | one | one |
| EPS 4 + 4-pin connectors | one | one |
| PCIe connectors | 2 | 4 |
| SATA connectors | 6 | 6 |
| MOLEX connectors | 4 | 4 |
| Floppy connectors | 0 | 0 |
| Digital | No | No |
| ICUE Compatible | No | No |
At first glance we can already see that the Corsair TX650M is much more modern , with a more updated ATX standard. We also find that there are two steps of difference in terms of efficiency certification, since the CV650 has 80 Plus Bronze and the TX650M 80 Plus Gold , and with these two things alone we can assume that the TX family font is quite superior.
This means that the TX650M has better internal components, better adapted to modern hardware, and therefore means that it will be a longer-lasting power supply in the long run, although both have the same guarantee. However, the TX650M will also help us to save good money on electricity because its efficiency is much higher .
Also noteworthy is that the TX650M has a slightly larger fan, and while both sources lack Zero RPM functionality, this larger fan will also be quieter, at least a priori.
In relation to the cables, the CV650 is not modular while the TX650M is semi-modular , which means that except for the ATX and EPS cables that are fixed at the source, the rest of the wiring is modular and will facilitate installation in any pc case. In addition, these modular cables are flat , and it should be noted that it has two additional PCI-Express connectors , allowing us to connect configurations of various graphics cards, something that we will not be able to do with the CV650.
Is the Corsair TX650M worth paying more?
Given the technical characteristics of both power supplies, our verdict is yes. With the Corsair TX650M we will not only have a more modern power supply adapted to the latest hardware, but it is much more efficient, has semi-modular wiring, is quieter and has better connectivity, so we believe that the price difference does. it’s worth it.
Now this does not mean that the CV650 is a bad font, nothing further. It is an excellent option if you are on a tight budget but still want a good quality font but you can do without the advantages that we have specified above.
