Essentially and at first glance, the biggest difference we find between these two power supplies is obviously that the CV750 has all the fixed wiring while the CX750M is semi-modular, and only the cables for 20 + 4 pin ATX and 4 + 4 pin EPS connectors are fixed and the rest is modular, so we can’t connect them if we don’t need them. However, the price difference between the two sources is quite remarkable, so is it worth paying more for the semi-modular model?
Corsair CV750 vs CX750M, technical comparison

| Type | Analog | Analog |
| Efficiency certification | 80 Plus Bronze | 80 Plus Bronze |
| + 12V rail | Simple | Simple |
| Wiring | Permanent | Semi modular |
| Cable type | Thick | ATX and EPS thick, the rest flat |
| Fan | 120 mm | 140 mm |
| Zero RPM mode | No | No |

As we have already stated before, both are 750 watt power supplies with an 80 Plus Bronze efficiency certification, which guarantees a 85% minimum efficiency at 50% load (which is the typical usage state for a PC power supply). Both sources also have a single + 12V rail, and both are analog sources and not digital, so they are paired so far. However, their similarities end there, because now things are changing a lot.
For starters, the CX750M is a much more modern source and proof of this is that it complies with version 2.4 of the ATX standard while the CV750 remains at version 2.31. It is not for this reason that it is a worse source, but as we will see next, there is a lot more that changes, starting with what we also mentioned which is the type of wiring. , well the CV750 has all fixed wiring and the CX750M is semi-modular, with only the ATX and EPS connection cables attached to the source.
Continuing with the wiring we find another fundamental difference in the shape of the cables as the Corsair CV750 has all the thick cables making it much more uncomfortable to pass through the box while the CX750M only has both. thick cables that are attached to the source, the rest being flat wiring which is much easier when it comes to channeling it through the box.
In addition, despite the fact that the two sources have the same power, we can also find a rather significant difference in the connectors, since the CV750 only has two 8-pin PCIe connectors while the CX750M has four, which makes it compatible with high-end graphics and even with multi-GPU configurations.
Continuing with the differences, we find that the fan is also different; While the CV750 model has a 120mm fan, the CX750M has a 140mm fan, which means the latter will have better cooling and be quieter, although neither of them have hybrid fan technology. (Zero RPM) which allows it to turn off when the source is not subjected to a significant load to reduce the noise emitted.
In view of this, however, we find an advantage in favor of the CV750 which has lost everything so far, namely that it is relatively smaller and will therefore be more compatible with cases that have little space. This font is only 125mm long by 160mm on the CX7650M, making it practically a font SFX-L in terms of size and it will be much easier to install in small boxes.
Apart from everything that we have already commented, we do not find any major differences between one source and another, obviously leaving aside the price because there is a difference of 25 dollars between one and the other, which we leads to the next section of this article which you can read below.
Is it worth paying more for the semi-modular model?
As we saw in the technical comparison, the Corsair CX750M is a far superior model to the CV750 despite the fact that both have the same horsepower and even the same efficiency certification. Semi-modular cabling is certainly an advantage over fixed cabling (although it is true that the most desirable would have been cabling 100% modular), but the fact that almost all cables are flat is a plus that cannot be overlooked either.
On top of that, the CX750M is a source that supports a more modern ATX standard, has a higher number of connectors, and also supports multi-GPU setups, which the CV750 cannot boast of. As if that weren’t enough, the CX750M has a 5-year manufacturer’s warranty versus 3 years for the other model, which will also provide additional peace of mind to the user.
In short, the CX750M is “much more source” and really, with a price difference of around 25 dollars, it is well worth opting for this model because it is notably superior, and will offer the user more comfort. , versatility, compatibility. same peace of mind if you take into account the two additional years of warranty that it includes.
So our verdict is that yes, the price difference is worth paying, but not just for the semi-modular cabling but for that in combination with all the other benefits that this power supply offers. In addition, already put in sources that revolve around 100 dollars, 25 dollars is not that they make a huge economic difference and more if you are looking for the quality guarantee that a manufacturer like Corsair gives.
