Palit RTX 2070 Game Rock Premium Edition review - Heavy chunk with good performance | igorsLAB | Page 4

We know some heavy guys, but with the current GeForce-RTX models, Palit has taken a lot to heart, which has been repeatedly called for in the previous models. And the Game Rock Premium Edition (GRPE) really lives up to its name, because the part is a real mountain of graphics card, almost a small mountain. But I don't want to pre-empt the test, but I can't hide the fact that I was already quite tense...

Power consumption and loads

Palit hits the default values from the BIOS extremely precisely when it comes to power consumption. This is not really the case with every card, but here it works perfectly. The 12.4 watts in the Idle are good, because there is also a lot of RGB on board. Under full load, the 215 watts stored in the firmware are reached precisely and in no situation is exceeded in any situation, both during gaming and during stress tests.

Here is a short excerpt from what Palit gave this card in the firmware of limits:

The voltages are in the expected range, with the oc’s permissible board power being the limiting factor, not the voltage. One notices very clearly that Nvidia deliberately limits here before a possible maximum is reached.

The load distribution on the rails is good, because the maximum 5.5 amperes of the motherboard slot are never exceeded. The external power supply connections also remain just under 200 watts.

Power supply design and peak loads/currents

As I have already demonstrated in detail in my basic article “The fight of graphics card against power supply – power consumption and load peaks demystified”, there are also temporarily higher loads in the millisecond range, which are unfavorable in case of unfavorable designed or improperly equipped power supplies can already lead to unexplained shutdowns. The TBP (Typical Board Power) measured by the graphics card manufacturer or the reviewers does not really help for a stable design of the system.

Peaks with intervals between 1 and 10 ms can lead to shutdowns with very fast-reacting protective circuits (OPP, OCP), especially for multi-rail power supplies, although the average power consumption is still in the norm. For the Palit RTX 2070 Game Rock PE I would therefore calculate with 300 watts to have enough reserves in case of a case. A short excerpt with high resolution now show us the 20 ms intervals, how I run them automatically for valuation:

Detailed recording of average power consumption and flowing currents

As usual, I now also set aside the power consumption and the flowing currents as detailed graphics of my oscillograph measurements. A service that hardly anyone else offers and which shows how the maps “tick” in detail:
