Csupati Posted December 20, 2023 Share Posted December 20, 2023 Hi. Guys, somebody know what is the max power draw on the P751 that a 9900k can make, at what wattage and voltage? Lets say it has the AliExpress water cooler. HP Omen Transcend 16 13700HX/32GB 4800mhz/RTX 4070 105W/QHD 240Hz IPS. Link to comment Share on other sites More sharing options...
Meaker Posted December 22, 2023 Share Posted December 22, 2023 If it's like the 870TM then a fair amount but there are several power limits you have to raise. 1 Sager NP9877 Hybrid Watercooled setup, D5 pump with dual 140MM fans integrated into custom stand. All controlled via temp outputs from GPU and CPU. 17.3" 1440p 120Hz display + 32" 4k MSI IPS 160Hz display 9900KS @ 4.8Ghz (47x102Mhz) All core, delid with rockit IHS, liquid metal RTX 3080 @ 1920/8000 shunt mod 32GB (16x2 dual rank) 3280Mhz DDR4 CL16 1TB SM961 SSD 2TB SN770 SSD Dual 330W PSU Link to comment Share on other sites More sharing options...

So it can handle like a desktop mobo, 200-250W only cpu? HP Omen Transcend 16 13700HX/32GB 4800mhz/RTX 4070 105W/QHD 240Hz IPS. Link to comment Share on other sites More sharing options...
Meaker Posted January 3 Share Posted January 3 In my machine the 9900KS I do run mine heavily undervolted at 4.8Ghz to give the system a reasonable chance.

I doubt that you will be able to sustain much more than 150 to 160W on a semi-constant basis and with a special heatsink. Maybe up tp 200W with a single run of cinebench but not for very long.

I am working on my P750 so basically the same and I have the AliExpress cooler, but the air cooler. I have difficulty keeping 90w cool with a custom fan curve, fans full blast would probably be fine though. But I think I can do better, but I am shooting for being able to cool ~100w consistently so something like 200w would be too much I think. I currently have a 8700k in it, but have a 9900k I will try eventually too. But - on the GPU side it does a really good job keeping it cool, I just need to dial in the CPU side contact.
