Slightly Bent: 600W 12V-2×6 / 12VHPWR 90° Seasonal Adapter Cable in Test

Slightly Bent: 600W 12V-2×6 / 12VHPWR 90° Seasonal Adapter Cable in Test

Today I'm testing the second original 90 degree cable, and since I can screw it up, I have nothing to complain about. Because if the power supply cable hits the side panel of the case, good advice is often expensive. Especially then when the NVIDIA adapter is inseparably integrated with the graphics card head. For exactly such cases, Seasonic now offers a special 90-degree cable designed to circumvent this problem. Today's test aims to ask what a cable can and cannot do.

An important preliminary note

I am not responsible for the design and limitations of the new connectors and I still see them as almost possible as long as all external influences and build quality are correct. However, there is not much room for mechanical influences even with such adapters. It is therefore very important to educate the user on the correct handling (visual, tactile, and tactile) and perhaps also limit the power consumption to 450 watts. However, in today's testing, I measured 517W at first and then 600W, although some of it is supplied via the PCIe slot. And quality would (should) be an important factor if it wasn't just about feeling safe.

Technical data and implementation reasons

The fact that Seasonic, like Be Calm!, only offers the corner cable in one version has solid technical reasons, which I already explained in my article about head quality and reviews on the Asus head. When installed horizontally in a computer, i.e. hanging and not standing (using a mounting cable), the cable leads up on Ausus cards with flip-tipped heads, but down on standard sockets from all other manufacturers, which is usually the case. However, if the card is standing vertically, for example, in an extension with a raised cable, the cable on the Strix extends toward the side wall, which doesn't make sense; On all other cards, it extends towards the back, which makes more sense. I still ask myself today why Asus made this change that makes no sense in my opinion, and which is also electrically harmful, as the higher damage rates prove.

Seasonic also decided to place the live cables indoors only, since the potential bending and levering movements are less than those of outdoor cables with a larger bend radius. You should know that the manufacturer of Seasonic first bends the pre-crimped cables and then compresses them into the plug before lengthening (i.e. cutting) the straight piece of cable. This has the advantage that laying cables is easier and safer. This is commendable, and is certainly more flexible, but unfortunately it excludes another variable.

What MSI has copied is the coloring of the plug on the side of the power supply. As long as there is still some blue flash in the eye, the connector is not inserted far enough into the head. This is just another small security feature, but you can do it this way. In fact, you can make it visible on both sides as standard, but PCI SIG is clearly not just color blind. I liked the idea of ​​MSI at the time and I'm also with Seasonic when it comes to color highlights.

If you then insert the connector very tightly and insert it all the way, the blue will disappear from your field of vision and everything will be fine.

We can see from the side view that it is possible to create a true 90 degree jacket in such a small space using solid 16AWG cables and a safety jacket, if the cable insulation is not as thick as in a quiet case! It remains a little more flexible. Secure locking of the upper half onto the connector is ensured in any case, even if you try to bend it with brute force. Nothing happens without the tools and massive leverage. Fortunately, the use of weaker, more flexible cables with a thinner PVC sheath has been abandoned for safety reasons and I take my hat off to the manufacturer who managed to do this with 16AWG.

The quality of the injection mold is good, you can't complain here either. Manually inserting it into several different and even virgin graphics cards with the Hweader 12V-2×6 was a little tight, but with an audible click. So that's good. And yes, the adapter is also compatible with the “old” 12VHPWR standard. This is what I have to do in preparation for today's test and what I will also do in the future when it comes to testing such cables or adapters.

Those affected by potential failures certainly fall into the thousandth range, and even then it is not clear where the user begins to take at least some of the blame and where the connector itself simply provokes errors. No wonder I bought an expensive ASUS card for these tests, because I really want to include at least this factor.
