Power supply
To quote Igor:
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 cards or power supplies to indicate as the performance value? With power supplies you can be relatively sure, but what about the graphics cards?
And in return, you are always amused by the power supply computers of the graphics card providers, which often spit out much higher values than what one finds in the normal measurements. Anyone who knows my graphics card tests knows, however, that I always also use the so-called spikes (<20 ms) mit angebe, diese deutlich höheren Werte aber auch gern relativiere. ms)="" mit="" angebe,="" diese="" deutlich="" höheren="" werte="" aber="" auch="" gern=""></20 ms) mit angebe, diese deutlich höheren Werte aber auch gern relativiere.> Because modern power supplies should be able to put away such very short load peaks easily. Should.
But can they really? And above all: how long ? And what please distinguishes a game now from a permanent load such as e.g. Calculations or a stress test? This is exactly the question I am now looking into, because apparently and unfortunately no one else really cares about it in detail. And what about the protective circuits installed in the power supplies?
When selecting the power supply, Igor was able to convince me that, despite the small budget, we do not have a used power supply (origin? Age? Previous use? etc.) or even use a cheap "China-Böller" for this project. If it hasn't already happened, I strongly advise you to look at the following article: And it has done BOOM. As a logical consequence, I then resorted to a decent brand edible power supply.
Of course, a budget calculator does not require a high-end Platinum device with 1000 watts. Most large manufacturers offer not for nothing the more expensive devices but also even smaller series for price-conscious buyers. Privately, I've only been using Seasonic power supplies for years, and because I haven't missed a single one of them, the choice was made quickly. The proven S12III series enjoys an excellent reputation and the 500 Watt model will be absolutely sufficient for this project.
Typical Seasonic, even the inexpensive S12 does not allow itself any patter spacing during processing and with the black flat cables it fits optically into virtually any system. The built-in fan is noticeable under load, but at a price of well under 50€I can certainly hurt this. As a basic reading, I can only recommend the already teased Greundlagen article:
