I was looking for a motherboard costing around 450 dollars in my country, the Asus Prime Z790-A with WiFi and DDR5. It has 16+1 60 Amps, but I've heard it's insufficient for the 13900K. Is this accurate? I'm planning to overclock and reduce voltages as much as possible while keeping a stable 6 GHz frequency. If this board isn't powerful enough, let me know! Also, my DDR5 RAM will be set to 7000 MHz.
Beyond the number of power stages and current ratings, factors like efficiency curves and heatsink performance play a role. If using IR3550s on this board, expect around 24W during peak loads at standard speeds—plenty for the heatsink to manage with little to no airflow. The main concern lies with the board itself. ASUS’s 6-layer DDR5 design isn’t ideal for Z790, pushing 7000MT/s close to practical limits. For better results, consider upgrading to an 8-layer model such as Strix Z790-F or Z790-E, or switch to MSI or Gigabyte Z790 boards, which generally offer stronger 6-layer configurations.
I appreciate your question! It sounds like you're trying to figure out the best RAM setup for your build. Let me simplify things a bit.
You're considering different RAM speeds and types, especially for a gaming PC. The main concerns are compatibility, cost, and performance. You mentioned wanting a white build and are looking at options like the ASUS ROG STRIX Z790-A. It's true it doesn't support DDR5, which might limit future upgrades.
If you're going with 6800 MHz CL34 RAM, it should work fine for now, especially since gaming is your main focus. The 7000 MHz option could offer better performance but might be overkill unless you plan to upgrade later.
Your Corsair AX 1200i and PSU are solid choices, so power stability shouldn't be an issue. Just make sure the RAM sticks are compatible with your motherboard and follow the manufacturer guidelines.
Let me know if you want more details on any of these points!
The simplest method to determine whether a board is an 8-layer or a 6-layer model is to check G.Skill's 7200MT/s CL34 kit directly on G.Skill’s site. The 8-layer boards will appear there while the 6-layer ones won’t. A 6800 CL34 should fit most Z790 boards, and you probably won’t notice a significant speed boost. For a 7000 MT/s model, the best case is that the XMP settings are unstable or don’t activate at all, so you’d likely have to lower the speed to 6800MT/s. This option saves some money and offers better reliability. If you need a white board, I still recommend something like the MSI Z790 Edge—it has a superior memory layout and ASUS’s BIOS is generally easier to work with than ASUS’s. While I still favor ASUS for its speed during overclocking, if you haven’t used either in a year, you can quickly set up an OC on MSI’s BIOS before trying on an ASUS board. The white Apex board is impressive, but it costs around $800 and there are reports of quality issues with ASUS boards, including bent units and high failure rates. For the power supply, your current unit (presumably still functional) is performing well, handling overclocks to 13700K with good efficiency. Running at 5.6GHz P cores and 4.5GHz E cores, it can manage heavy synthetic loads while drawing nearly 400W, and the 6900Xt handles over 500W under stress. If you plan to undervolt the CPU, expect lower power consumption compared to my setup.
