ASRock B660m-itx/ac power limits - 12600K OK?

Lumen

Yeah I know, I should have asked here first, but I got excited by RTX availability.

I've ordered parts for an ITX build from mindfactory.de (routed through mailboxde). Parts are:

• Case: NZXT H1 v2 Mini-ITX 140mm-AIO, 750W Gold PSU Gen 4 PCIe Riser Card Schwarz
• GPU: 10GB Palit GeForce RTX 3080 Gaming Pro LHR Aktiv PCIe 4.0 x16
• CPU: Intel Core i5 12600K 10 (6+4) 3.70GHz So.1700 WOF
• SSD: 2TB Samsung SSD 980 PRO Heatsink 2TB M.2 NVMe PCIe4
• RAM: 32GB PNY XLR8 Low Profile DDR4-3200 DIMM CL16 Dual Kit
• Motherboard: ASRock B660M-ITX/AC DDR4 Intel S1700 MITX

I'm trying to work out whether the motherboard has enough grunt for the CPU. Apparently the 12600K can draw up to 150W.

I've read in a couple of forums that the motherboard might only support 100W (PL2) or 150/180W (PL1/PL2).

Presumably 150/180W would be fine.

What's the truth? This is the spec sheet for the motherboard:

...and the CPU power chart:

12600K doesn't seem to gain much performance with power limits removed anyway

That said, this tier list rates the B6660M-ITX poorly:

This a B660 HDV in mITX format with WIFI. While it is bad, with weak VRMs, and poor connectivity, it has some use in SFF Home Theatre PCs. General users should avoid, but if you know what you are doing some use can be found.

TBH, after all the shady sh*t ASRock have pulled with youtube reviewers (e.g. buildzoid, Gamers Nexus, Hardware Unboxed) I can't recommend them anymore.

Thanks KOK, I'll see if I can pull it from the order.

Managed to find a ASUS ROG Strix B660-I Gaming WiFi on alternate.de for €205.

Hopefully that should be OK!

Balls! The substitute (much better) mobo only supports DDR5.

So I have "32GB PNY XLR8 Low Profile DDR4-3200 DIMM CL16 Dual Kit" to offload and need to order some DDR5...

The NZXT H1 v2 was quite a bit more fiddly and worse documented than the NR200 build I did at Christmas 2020, but I like the way the GPU hangs vertically, much more secure for a heavier card like the 3080.

Reminds me of when I bought a 5820K and failed to realise it required DDR4 during a time of stupid prices!

The B660M is not a gamer's chipset. It only has 6 PCIex 4.0 lanes. (6 not 16!)
