MSI Radeon RX 580 Mech 2 8GB – Polaris battle suit from the crowbar

Let's start with the values for the individual load states, because amD had actually made the biggest and long overdue innovation here. In both multi-monitor setup and hardware-accelerated video playback, performance levels have decreased significantly as long as the resolution is the same on all connected monitors. In the Idle, the MSI card with the measured 16 watts for the entire card cannot set any standards, but we will see why.

With 217 watts in gaming, you are already significantly higher than most competitors and the impossible 253 watts in the stress test also mark the extremely high power limit that MSI gives its Polaris fighter. Whether and how this can be used later, or whether this is all full pipe on small sparrows, I will clarify later.

However, the peak values in the stress test let me fold the chin draw down. Almost 390 watts are of course already very fat, even if they are only small but deeper needle stitches. Modern and good power supplies can do this, of course, and because of Furmark & Co you won't have to install a potent 800-watt power supply, but dominations, that's really crass.

But we also see that the increased clock speed of the RX 580 and MMI's interpretation, which also wants to keep bending and breaking, has its hot price. In order to achieve such clock rates and, above all, to be able to maintain them in the long term, there must of course also be sufficient voltage. Let's first look at the appropriate diagram and be amazed that MSI has once again succeeded in letting quite constant voltages lie. By the way, we will encounter the short-term peaks of up to 1.25 volts in the stress test again later.

With a maximum of 1.25 and an average value of approx. 1.1 V is quite high up the scale. You can do that, no question. But you also have to get it cool, but I'm still testing that.

Load on the individual 12V rails

First, a small comment on the external 12 port. With a maximum of 203 watts (typically 185 watts for gaming), this is all enough, even if two 6-pin connectors might have been more convenient. But no matter, it's enough and only that counts in the end. Only that with the extreme OC should be considered again, because I beat the part with a lot of cunning and trickery to over 230 watts. But then you can throw away the norm. The card with a bit of bad luck, by the way. Normally, however, you don't get there at all.

Now let's consider the maximum load of the PCI Express motherboard slot (PEG) at 12 volts. The PCI SIG sets a maximum of 5.5 amperes for the motherboard slot as the standard. This is converted to the recorded power exactly 66 watts. By the way, the often collated 75 watts are fundamentally wrong and result only from the ATX specifications, where a power supply within the scope of the tolerance could also supply a little more than 12 volts. However, the actual standard only includes the flowing currents, so that we consider the maximum 5.5 A to be binding:

If we put the load on the motherboard together again as a bar graphic, then we can see very clearly how well the specification was met this time. It is important that the permanent load is still fully in the green area. And that's exactly what it does loosely. Fine.

Power consumption and currents in detail

There are 16 watts in the idle, which of course also has a positive effect on the flowing currents. Of course, this also suits the fan stop, which still works in the loadless state even in the closed housing.

With the gaming loop you can see very nicely the rule rage of Power Tune, because the tips are clearly above what we measure as an average value. But it's not something that a power supply with a properly equipped secondary side couldn't plug away and smooth iron. Only horn-old China böller should already be sweating here.

However, the torture test then shows significantly naser rashes, which almost shoot through the ceiling. Perhaps MSI should have been based on a different monitoring and a somewhat more restrained power limit?
