Kaby Lake CPU support is blocked. Dell never released a BIOS update to support 7th gen Intel processors on the Z170 board. The i7-7700K and i7-7700 are physically LGA1151-compatible but the R5 failed Dell's internal validation testing for Kaby Lake — no BIOS update will ever be issued. The i7-6700K is the absolute CPU ceiling for this machine.

K-series upgrade requires hardware additions. Upgrading from any non-K SKU to the i7-6700K or i5-6600K requires the VRM MOSFET heatsink (Dell P/N J46J2) and an 850W PSU. Running a K-class processor without the VRM heatsink risks heat damage to the voltage regulator under sustained load. Liquid cooling is strongly recommended.

Third-party PSU: proprietary GPU_PWR header. The Z170 motherboard uses an auxiliary 8-pin connector labeled GPU_PWR. When fitting an aftermarket ATX PSU, this header must be connected using the CPU 4+4 pin cable — not a PCIe power cable. Connecting incorrectly will cause a black screen on boot.

Requires VRM heatsink (Dell P/N J46J2) and 850W PSU — same requirements as the i7-6700K.

On non-K SKUs the heatsink is absent from the factory; do not skip this step.

This is the CPU ceiling for the R5 — factory option on K-SKUs only.

Upgrading from a non-K SKU requires VRM heatsink (Dell P/N J46J2) and an 850W PSU. Liquid cooling strongly recommended; the stock air cooler is insufficient at load.

Manufacturer
GeForce GTX 1660 Ti (Blower)
120W ~240mm 2-slot 6GB GDDR6

Blower-style versions (e.g. PNY Blower, ZOTAC TWIN Edge) confirmed fitting the R5 chassis. Blower cooler preferred in this case for exhaust management.

Community
GeForce RTX 2060
160W 229mm (FE) 2-slot 6GB GDDR6

Confirmed working on the stock 460W PSU. FE and compact dual-fan models fit without clearance issues.

Community
GeForce GTX 1080 Ti
250W 267mm (FE) 2-slot 11GB GDDR5X

850W PSU required — the 460W OEM supply cannot support this card's peak draw alongside the rest of the system.

FE (267mm) fits the R5 chassis. Most AIB cards run 280–305mm; verify length before ordering.

Warning
GeForce RTX 2070
175W 229mm (FE) 2-slot 8GB GDDR6

850W PSU strongly recommended — combined system draw approaches the 460W limit under sustained load.

FE and dual-fan compact models confirmed fitting at 229mm.

Warning
GeForce RTX 2080
215W 267mm (FE) 2-slot 8GB GDDR6X

850W PSU required. FE card is 267mm and fits the R5 chassis.

Most AIB partner cards exceed 280mm — measure before purchasing any non-reference version.

Warning
GeForce RTX 3070
220W 242mm (FE) 2-slot 8GB GDDR6

850W PSU required. FE card is 242mm and fits within the ~280mm clearance.

Most AIB cards are 280–320mm — FE or compact dual-fan models only. Check dimensions before ordering.

No community confirmation in an Aurora R5 found at time of writing — upgrade is based on known clearance and power figures.

Warning
GeForce RTX 3080
320W 285mm (FE) 2-slot FE 10GB GDDR6X

Founders Edition is 285mm — 5mm over the confirmed ~280mm clearance limit. All AIB partner cards are 305–335mm and will not fit without removing the front intake fan.

Incompatible
GeForce RTX 4090
450W 336mm (FE) 3.5-slot FE 24GB GDDR6X

3-slot card at 336mm — far exceeds both the case clearance and the 850W PSU capacity. Not viable in any R5 configuration.

Incompatible
Radeon RX 7900 XTX
355W 287mm (ref) 3-slot AIB 24GB GDDR6

All available AIB cards are 3-slot and 287–330mm. Both the slot count and length exceed R5 case constraints, and 355W TDP exceeds the 850W PSU's effective headroom.

Best Bang for the Buck
Best performance gain per dollar on the used market
CPU Recommendation
Core i7-6700
The i7-6700 is a factory R5 SKU — a guaranteed drop-in swap with zero extra hardware. You get a jump to 4 cores / 8 threads at 3.4GHz base on the stock PSU with no VRM heatsink or liquid cooling required. Used pricing is typically $30–60, making it the highest-value CPU move on this board.
GPU Recommendation
GeForce RTX 2060
Community confirmed stable on the stock 460W PSU — no PSU upgrade needed. The FE at 229mm fits the R5 chassis with room to spare. It's a massive step up from a GTX 970 or 1060 and delivers solid 1080p performance. Used pricing of $100–150 makes the performance-per-dollar ratio hard to beat on this platform.

CPU Recommendation
Core i7-6700K
The absolute CPU ceiling for the R5. Runs at 4.0GHz base with an unlocked multiplier — the only Skylake CPU that gives you overclocking headroom on this board. Same core count as the i7-6700 but noticeably faster under sustained load with the right cooling.
⚠ Requires VRM heatsink (Dell P/N J46J2), an 850W PSU, and liquid cooling is strongly recommended. Skipping the VRM heatsink risks heat damage under load.
GPU Recommendation
GeForce RTX 3070 FE
The most capable GPU that fits within the R5's ~280mm clearance (FE is 242mm). Offers a massive performance leap over everything else on this list — capable of solid 1440p gaming — and is the best card this chassis can realistically house.
⚠ Requires the 850W PSU. FE edition only — most AIB cards run 280–320mm and won't fit. No R5-specific community confirmation at time of writing; based on known clearance and power figures.
Core i7-7700K
LGA1151 physical fit but Kaby Lake is BIOS-blocked on all Z170 boards. Dell confirmed R5 failed internal validation — no update ever released.
Core i7-7700
Same Kaby Lake block as the 7700K. Dell's BIOS restriction applies to all 7th gen Intel parts regardless of TDP or K-suffix.
Core i7-8700K
Coffee Lake (8th gen) requires Z370/Z390. Electrically incompatible with Z170 despite sharing the LGA1151 socket — will not POST.
Core i9-9900K
Coffee Lake-R (9th gen), LGA1151 socket. Requires Z390 chipset. Electrically incompatible with Z170, same issue as 8th gen Coffee Lake.
RTX 3080 / 3090
RTX 3080 FE is 285mm — over the ~280mm clearance limit. RTX 3090 FE is 285mm and 3-slot. All AIB versions of both run 305–340mm.
Any AMD Ryzen CPU
All AMD Ryzen CPUs use AM4 or AM5 sockets. The R5's LGA1151 socket is Intel-only — no adapter or workaround exists.
RTX 2060 confirmed stable on the stock 460W PSU, replacing a dual GTX 970 setup.

User reported the RTX 2060 running without issues on the stock 460W supply; combined system draw stayed within safe margins.

Compact FE and blower-style RTX 2060 models verified to fit the R5 chassis without clearance issues.

GTX 1660 Ti (blower-style) confirmed fitting and working in the Aurora R5 on a 460W PSU.

PNY blower model and ZOTAC compact versions specifically noted; blower exhaust recommended for R5's restricted internal airflow.

Users noted that open-air dual/triple-fan 1660 Ti cards may create thermal issues as hot air recirculates inside the case.

Third-party ATX PSU (EVGA SuperNOVA 750 G3) confirmed dropping into the R5 bracket without modification.

The R5 uses standard ATX PSU dimensions — any modern ATX unit up to ~150mm deep fits the swing-out bracket.

Critical caveat: the motherboard's GPU_PWR 8-pin header requires the CPU 4+4 pin cable from the new PSU, not a PCIe power cable. Wrong connection causes a black screen on boot.

Dell Community →
i7-7700K installation attempted — Dell officially confirmed no Kaby Lake BIOS support after internal testing failure.

Some users reported the R5 posting with a 7700K after sourcing a third-party firmware flash, but this is unwarrantable and not reproducible across all board revisions.

Dell's official position: the R5 system failed validation with the 7700K under load, and no BIOS update will be released. Do not pursue this upgrade path.
