Core i5-12600K + RX 9070 XT: bottleneck check

5%

Balanced at 1440p.

Well matched at 1440p. The Core i5-12600K is the slightly busier part, by about 5%.

This is the classic pattern: at 1080p the Core i5-12600K is the limit (12%), while at 4K the RX 9070 XT takes over (17% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply

CPU 150 W + GPU 304 W + about 100 W for motherboard, memory, storage and fans gives an estimated peak load of 554 W. We recommend a 750 W unit (80 Plus Gold or better) so transient spikes from the graphics card stay inside the PSU's comfort zone. Try other pairs in the PSU calculator.
