Who doesn’t know the great 80-Plus logo on most power supplies? This label suggests a certain efficiency and contributes not insignificantly to image building. 80 Plus Platinum? This just has to be good! Or maybe not so really? A document that I received today shows how the money printing machine 80 Plus is ticking in such a way, i will tell [...]
The idea of testing power supplies not only synthetically on the chroma, but simply once in the usual setting of a possible user, is actually not even that absurd, but usually fails because of the amount of test objects. And where do you get these power supplies after all? From the manufacturer! And in order for him to overcome exactly this step [...]
Well, that sounds more dramatic than it might be, although… The devil is in the test setup as usual. The MSI GeForce RTX 3090 Gaming X Trio (OC), MSI GeForce RTX 3080 Gaming X Trio (OC) and MSI GeForce RTX 3070 Gaming X Trio (OC) are tested on two different high-end systems. Of course @stock and with a maximum OC, which can be added under [...]
The discussions about what current flow various 6-, 8- or now even 12-pin sockets can survive are as old as these sockets themselves. But while over the years one could see the odd experiment or two, the 12-pin Micro-Fit 3.0 connector is new. This in turn naturally aroused human curiosity and this is exactly where my longtime friend Aris [...]
Since the new 12-pin sockets are so well known and one of the NDAs has fallen in the meantime, one should also clean up some of the rumours, mistakes and confusion. In the end, only a small communication lapse led to half of the power supply industry suddenly gasping for breath in panic and hyperventilating within a few days. But I want to unravel [...]
Who measures a lot measures crap. This rule applies as long as one does not actively deal with the circumstances and requirements and is not prepared to invest a lot – mostly private – time in its exploration. I started working more intensively on the power consumption of graphics cards in 2014 and to find a really good solution. In [...]
The previous practice of real-time measurements (even over longer periods of time) only with the oscillographs is certainly not bad and it also allows deep insights into the switching behavior of graphics cards and CPUs due to the high resolution, but it is always only possible possible to capture a sub-area of the overall system. Interactions [...]
One knows and hates it, the beloved moment when a power supply suddenly switches off in the middle of a game, even though it is new and shows no other conspicuous features. The user’s annoyance becomes even greater when you think you have calculated the power supply size correctly. But is what the manufacturers of graphics cards or power [...]
You know and hate it, the beloved moment when a power supply suddenly switches off in the middle of the game, even though it is new and shows no other abnormalities. The annoyance of the users becomes even greater if one believes that the power supply size has also been calculated correctly. But is that enough for the manufacturers of graphics [...]
