There’s no such chip as the “Core i7-7600K” — Intel’s actual 7th-generation (Kaby Lake) lineup has the Core i5-7600K (a quad-core, no-hyperthreading overclocking chip, and the far more commonly searched budget K-series part) and the separate Core i7-7700K (quad-core with hyperthreading, the flagship of that generation). Given the naming pattern, this covers boards for the i5-7600K specifically, since that’s the chip that usually gets misnamed this way. Because this is a discontinued, 2017-era platform, expect to be shopping new-old-stock and used listings rather than fresh retail stock — prices below reflect that.

The picks, in detail
ASUS Prime Z270-K
The best-known budget overclocking board for the i5-7600K, with the BIOS-level multiplier and voltage controls the “K” chip is actually bought for.
- ATX form factor
- Full BIOS overclocking controls (multiplier, voltage)
- LGA1151 socket, DDR4 support
- Does the actual job an unlocked K-series chip needs
- Well-documented online for i5-7600K overclocking guides
- Discontinued stock, so pricing varies more than a currently-manufactured board
Gigabyte GA-Z270-HD3
The cheapest real Z270 board still findable today, with 2-way CrossFire support and the essentials for a straightforward overclocked build.
- ATX form factor
- 2-way AMD CrossFire support
- LGA1151 socket, DDR4 support
- Lowest price of any board on this list
- Still turns up as new-condition stock, not just used
- Fewer VRM phases than the premium Z270 boards, so keep overclocks modest
ASUS Prime Z270-P
ASUS’s base-tier Z270 board — fewer frills than the Prime Z270-K but the same core overclocking support for a lower price.
- ATX form factor
- BIOS overclocking support
- LGA1151 socket, DDR4 support
- Cheaper than the Z270-K while keeping real overclocking headroom
- Simple, well-tested reference-style layout
- Fewer USB and fan headers than the Z270-K
ASUS ROG Strix Z270F Gaming
A more feature-rich board with RGB lighting and better audio, sold new for $130-$180 when it was current — today’s listings run a wide range depending on scarcity.
- ATX form factor
- ROG-tier audio and RGB lighting (Aura Sync)
- LGA1151 socket, DDR4 support
- Best feature set of the boards on this list
- Strong overclocking VRM for a board in this generation
- As new-old-stock has dried up, some current listings run well above its original $130-$180 price — compare multiple sellers before buying
Gigabyte AORUS GA-Z270X-Gaming 5
Gigabyte’s higher-end Z270 gaming board, originally a $145-195 part, now most commonly found on the used market.
- ATX form factor
- 2-way SLI support
- LGA1151 socket, DDR4 support
- More premium feature set than the base Prime/HD3 boards
- Used listings can undercut the ASUS Strix equivalent
- Used-market condition varies — check seller ratings and return policy
Buying tips
- Double-check you actually have the i5-7600K and not the i7-7700K before buying — both are real chips, and mixing up the name is the single most common mistake on this exact search.
- Stick to Z270 (or Z170) chipset boards if you plan to overclock — B250/H270 boards are LGA1151-compatible but don’t unlock the multiplier controls the K-series chip is built for.
- Because this is a discontinued platform, prices vary far more than a currently-manufactured board — compare several listings (including used) before assuming any single price here is current.
