Hi everyone, Im buying some new parts and I ran into some confusion.
The new parts that Im getting are:

CPU- Intel Core i7-7700 3.6GHz
MB- Asus - B150M-C D3 mATX LGA 1151
HDD- Western Digital Blue Caviar 1 TB (7200RPM)
GPU- Gigabyte GeForce GTX 1070 8GB G1 Gaming
Case- NZXT Phantom 240 ATX

And the parts that Im taking from my current pc are:

RAM- Kingston 8GB DDR3-1600 Memory
PSU- Corsair CX 600W 80+ Bronze Certified

I thought everything was fine until I went to pc part picker and it found 2 possible issues...

1) Some Intel B150 chipset motherboards may need a BIOS update prior to using Kaby Lake-S CPUs. Upgrading the BIOS may require a different CPU that is supported by older BIOS revisions.

2) The Kingston - 8GB (1 x 8GB) DDR3-1600 Memory operating voltage of 1.5V exceeds the Intel Kaby Lake-S CPU recommended maximum of 1.35V+5% (1.417V). This memory module may run at a reduced clock rate to meet the 1.35V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum.

The second issue doesn't actually bother me that much, at least I think its no big deal (educate/ correct me if Im wrong), but the first one does. I know that this MB is compatible with the 6th generation of Intel cpu-s (Skylake) but it doesn't say anything about the 7th generation (Kaby lake). I specifically picked this MB bcuz I can use my DDR3 RAM and is a 1151 socket but as it seems it isn't that perfect as I hoped. All suggestions are appreciated :)

The issue with the board is that it was released for the 6th Gen CPUs (6xxx). Almost all of them will be compatible with 7th Gen CPUs like your i7 7700, but because the board was released before those CPUs existed, out of the box it doesn't know what to do with them and it won't boot. You can update the BIOS on those older boards and then they work just fine, but you need a working CPU to do that. That specific B150 board you're looking at **may** have been released a bit later and actually ship with a newer BIOS which supports your CPU out of the box, but it's almost impossible to find out what BIOS version the board ships with, so there's a good chance it straight up won't work. That's why the general advice is, just get a 7th Gen...

Probably shouldn't use your old ram, as it will likely result in stability issues or not even POSTing at all. If you want a Kaby-Lake CPU, then you wil want either a Z270, H270 or B250 motherboard, as older Skylake boards will require a BIOS update, which is impossible to achieve without a Skylake CPU.

That's why the general advice is, just get a 7th Gen board (any B250 board, for example), because they're guaranteed work out of the box.

RE the RAM, that 7700 CPU does still include support for DDR3L memory, but it going above 1.35V is out of spec for Intel and they have advised against it. If your budget was super tight you might consider taking the risk, but you're throwing down a bunch of cash here for nice high end components, why would you scrimp on RAM when it may well damage your CPU and reduce its life -> that's what Intel have told us 1.5V RAM will do.

My advice, just get a B250 board and buy a new dual channel DDR4 RAM kit for it. It'll cost you a little more, but it's all guaranteed to work out of the box and it'll run faster too.
