The Core i9 is Intel's (and the world's) fastest consumer processor yet. Going up to 18 cores, these are CPUs meant for enthusiasts and power users. In Intel's simple terms, the Core i9 is faster than the Core i7, which in turn is faster than the Core i5. But “faster” isn't always “better” for you.
If you are exclusively gaming and have no plans to make or render videos 16gb of ram is the sweet spot. On Intel CPUs ram provides very minimal performance gains so there isn't much reason to go for ram speeds above 3000 or 3200. 16 GB 3200mhz is the best bang for your buck.
But these remain negligible. Logically, the Intel Core i9-9900K runs much cooler than with Solder TIM: RECOMMENDED VIDEOS FOR YOU With nearly identical power dissipation and identical cooling conditions, we calculate a mean package temperature of 57°C for the Intel Core i9-9900K and 75°C for the Intel Core i7-8700K.
The i9-9900K also saw a slight boost for single-core performance when compared to its predecessor, seeing a score of 218cb. That's a mere 5% improvement to the i7-8700K. Still, it's one the best single-core scores I've seen when testing processors, comfortably beating the AMD Ryzen 2700X with a 25% difference.
Yes, you read that right. A 1-5% speed boost in gaming performance for the i9-9900k, even though the i9-9900k costs roughly 25% more than the i7-9700k! The near-identical gaming performance and lack of hyper-threading makes the i7-9700k the better-value choice for a gamer.
For pure gaming, the Intel Core i9 9900K is overkill, unless you're planning on an extreme build with a top-tier graphics card. For those that do more than just play games, however, the Core i9 9900K is Intel's fastest mainstream CPU.
To overclock i9-9900K, you first need to start CPU Ratio. Our target is 5GHz, so just type in “50” for the CPU Ratio. Then change Ring Ratio to 47. You can try your own Ring Ratio, but we suggest a Ring Ratio that is 3x less than the CPU Ratio.
Therefore, allow for a bit of headroom on top of this, the recommended power supply wattage we recommend for the RTX 2080 Ti and i9-9900K system is a 750W PSU. This power supply received 10/10 scoring on all fronts from JonnyGuru, in terms of performance, functionality, value and build quality.
NVIDIA RTX 2080 Super: Minimum 650W. We recommend at least 800W. NVIDIA RTX 2080 Ti: Minimum 650W. We recommend at least 800W.
Thermaltake Toughpower Grand RGB 750W
750 Watts will be more than enough for powering a single RTX 2080 Super or any better graphics card and in case you want to do SLI, then also it will be enough.650W is more than enough for your entire rig, even with OC. A good quality 550W may be enough, albeit, at a lower efficiency due to higher load percentage when fully stressed.
A 650W supply should be adequate for a system with a desktop CPU, even overclocked, and any single graphics card, unless you're aiming for overclocking records. (CPU power draw of as much as a KILOWATT has been reported during record runs using liquid nitrogen cooling.)
A true powerhouse, the GeForce RTX 2080 Ti will run even the most demanding game system requirements released today. Capable of running games with up to a DirectX 12 requirement. 1440p gaming on the GeForce RTX 2080 Ti is more than capable at running this screen resolution.
The fact of the matter is that most mid-range gaming PC builds can run on 450-600W PSUs, depending on the GPU, with a good deal of them landing ideal wattage around the 500-550W range.
For example, if the maximum power or combined TDP (total design power) of your system's present components is 300 watts, a 600-watt PSU would be a good fit. In a high-end system loaded with components that may peak collectively at 700 watts, a 1200-watt PSU would work well.
We recommend at least 700W. NVIDIA RTX 2070 Super: Minimum 650W. We recommend at least 800W. NVIDIA RTX 2080: Minimum 650W.
The perfect budget power supply that can fulfil all of your needs along with powering up the RTX 2070 Super is the Thermaltake Smart Pro RGB 650 Watts power supply which is also rated at 80+ Bronze.
The RTX 2070 at high useage consumes about 200Watts, that is about 17Ampers aproximately, so if the PSU rail that you are going to connect to the GPU supplies at least that ammount of amperes, it should work fine.
Gaming workloads don't exhibit the same level of stress and load as FurMark + Prime95 running simultaneously would. For something like an R5 and GTX 1060 or RX 570, 450W is plenty for these gaming configurations. You can get far on a 450W supply, assuming it's decent.
Power Consumption and Overclocking
The 9700K matched the 7820X with a system draw of 235 watts when running our HandBrake workload. The 9900K pushed consumption 9% higher hitting 255 watts which is 13% more power than the 16-core Threadripper 2950X system consumed.So, now our power requirements look like this: 200W for CPU/motherboard, plus 250W for GPU, plus 75W for other components, plus 100W for overclocking. This totals up to 625W. We recommend that you select a PSU that will meet your system's target power requirements when running at 50 to 80% of its rated wattage.
Intel Core i7 9700K processor review - Overclocking
- Leave base clock (bus) for what it is right now (100 MHz)
- Set the per core multiplier at a maximum of your liking:
- Example 1: 100MHz x 50 = 5000 MHz.
- Increase CPU voltage; though AUTO often works fine on many motherboards you can do it manually as well.
Your motherboard probably uses 50 to 150 watts, and each stick of memory requires about 15 watts. The processor needs between 80 and 140 watts of power.
