NVIDIA GeForce RTX 4080 Founders Edition 16GB Review – Faster than expected and much more frugal than feared

Today we can finally present the NVIDIA GeForce RTX 4080 Founders Edition (FE) including all technical details and the long-awaited benchmarks, because the suspense curve was already plenty big. Even though NVIDIA actually sees the card as the successor to the GeForce RTX 3080, it is still a challenge to the RTX 3090 and especially to the GeForce [...]


12VHPWR adapter for NVIDIA’s GeForce RTX 4090 – Two manufacturers, contact problems, bending radii and the human factor

The 12VHPWR adapter for the GeForce RTX 4090 is unfortunately already a kind of running gag and so the topic is meanwhile beaten by all more or less well-informed media. A little unemotional reappraisal would certainly not be a bad idea to calm heated tempers and put the whole thing back on its feet. Therefore, today’s article is not only an [...]


Infrared measurement: facts, fake or only colourful hocus-pocus? The bitter truth behind many “thermal images” and the simple reasons

In view of the “measurements” with thermal imaging cameras or equivalent smartphones that have appeared again and again lately, I want to bring last year’s article forward again today to show you the complexity of the matter and to explain why measurement is not the same as colorful imaging. One can “measure” more [...]

The daily scam on eBay: When the cheap Eastern Digital Green SSD of a top seller suddenly halves | Test purchase and warning

Let’s be honest: is there currently an SSD with 2 TB of storage available for under 50 Euros? If it were up to certain eBay “top sellers,” it probably would. This contradicts the search results in reputable stores, but maybe the little technology miracle is taking place just outside of the usual big online shops. For example, if [...]


MSI GeForce RTX 4090 SUPRIM LIQUID X Review – Cool and super fast

The GeForce RTX 4090 has been launched, and with the 12VHPWR port, we’ll have to see how it develops, and that’s exactly why we’re turning to the pleasant side of life today. It would be boring to just write about the adapter all the time. And those who are really fluid could also afford the MSI GeForce RTX 4090 SUPRIM LIQUID X [...]


Cause simpler than thought? NVIDIA GeForce RTX 4090, the scorched 12VHPWR connector and how to plug it in | Blind Test

Sometimes you also have to listen to your children and do a blind test once. Apart from the fact that there are obviously three or four adapter types with different solder pads and cables, the problem of the hot contact surfaces of the outer connectors must have a simpler reason. I already wrote on the subject of bending that the rigid pins in the [...]

This is how the 12VHPWR is done correctly: Crimping instead of soldering and how to supply the GeForce RTX 4090 with power properly

First there were bent cables, then annoyed buyers of the at least 2000 euro expensive NVIDIA GeForce RTX 4090, no matter which model or manufacturer. The manufacturer of the 4-pin adapter from 12VHPWR to 4x 8-pin for older power supplies was also careless. And, of course, we learned something once again in the course of our investigations. Since [...]

The horror has a face – NVIDIA’s hot 12VHPWR adapter for the GeForce RTX 4090 with a built-in breaking point

Those who are now beating up on the new 12VHPWR (although I don’t really like the part either) may generate nice traffic with it, but they simply haven’t recognized the actual problem with the supposedly fire-hazardous and melting connections or cables. Even if certain YouTube celebrities are of a different opinion because they seem to [...]
