So at the very least, you can set it to 190/190W, the performance loss from that is virtually non-existent. This might actually less pronounced with a 12700K, as it doesn't use such an aggressive voltage-per-frequency setup as the 12900K. Specifically regarding the motherboard, there are two connectors that go directly to it, the EPS that can be 4 or 8 pins (that is why it is called 4 + 4 pins), and you should know that some high-end motherboards require two of these connectors, and the 20 + 4-pin ATX, which continues with that split design despite the fact that only some low-pow. Going to 125/125W further improves the efficiency, and can still perform very competetively (almost the same) in all "lesser" full load such as gaming, but it will lose out a bit in fully multithreaded long rendering/encoding runs for example. The sweet spot is near 125 W, I'd say, but it also depends on the application."Įven going through the application performance results with a fine toothed comb, you can see that setting the power limits to 190/190W on a 12900K hardly loses any performance, but obviously needs 50W less power than the default 241/241W under very taxing load. Of course, such low limits will drastically reduce performance-you're trading longer runtime for lower overall power usage. The most energy-efficient configuration turns out to be 75 W, which would make the Core i9-12900K the second most efficient CPU in our test group, only beaten by the Ryzen 9 5950X. At 190/190, the 5600X can no longer keep up. While the default 241/241 configuration is less efficient than all Zen 3 CPUs, the Ryzen 7 5800X is beat as soon as you go below the 200 W limit. "We also looked at power consumption and efficiency at these TDP limits and found that there's A LOT of efficiency to be gained at lower power limits. This becomes clear when you read tests like this: Create a unique PC look with outstanding quality and material Compatible with L-Connect. In other words, as per usual in recent years, the higher-up CPU models are pushed quite far by default, and for the last little uplift in final performance, draw more power than necessary. Available for motherboard 24-pin, GPU dual 8-pin, and GPU triple 8 pin. Intel's only goal was to beat AMD in reviews when defining the MTP/PL, not to set a sweet spot that allows for the highest efficiency. You can even go lower than that with the limits. Have a nice day.Click to expand.That is a sensible approach. That’s it for today! Hopefully, the post was beneficial to you to understand the 4 pins and 8 pins connector for the CPU conundrum. Rather, you can go for 4 + 4 connectors to limit the cost as well as to get the best out of the system. Although the additional 4 pin connector will provide an extra 12V to your motherboard, the processor would hardly need this unless you do the extreme level of overclocking. On the other hand, the arrangement of 8 pins + 4 pins connector is just too much for even a core i7 processor. Having said that, to rip the benefits of a high-end PC, you will have to make that sacrifice. Add an 8 pin ATX 12V cable with it and your pocket will have to pay a good chunk of money. The p/n for a standard P4 is 39-01-2040 or equivalent. Some PSUs may have three or four 12 volt 4-pin connectors. I know buying a brand new PSU (Power Supply Unit) for a motherboard can be expensive. Most of todays motherboards supply their CPU with a separate 12 volt cable, which has 4 pins for ATX style (sometimes called P4) or 8 or more pins for EPS and non-standard high-power systems. I am not saying that the combination won’t just work at all it will for a time being but will also have the chance for the PC to crash. However, most of the old PCs have 4 pin connectors that can hardly power the 8 pin motherboard. Still the CPU and PCI-E cables/connectors seem to be 'equal'. However on the motherboard there are 2 8-pin slots for the CPU. Currently I am using an old Corsair HX750 PSU, which has only 1 8-PIN CPU connector. The recent processors as such core i5 or core i7 use a lot of overclocking to exert all the features of a high-end CPU and for this to happen, you might need 8 pin connectors. I am planning to buy MSI Z690 Tomahawk DDR4 motherboard with 12700K CPU. 1×4 8 Pin ATX 12V Connector – Safe and Fit Connector for Motherboard the PSU delivers power to the motherboard through two connectors, a 24-pin connector that delivers +5.5V, +3.3V, and +12V, and an 8-pin connector that.
