Core Ultra 5 245 is 14 cores and 14 threads on LGA 1851. Gaming plans it at 65 W (Processor Base Power). The power-limit profile uses 121 W (Maximum Turbo Power, published). With a Radeon RX 9070 XT, the gaming total is 426 W and the minimum size is 550 W.
Processor Base Power and Maximum Turbo Power from this SKU's Intel specification page. Maximum Turbo Power is an all-core turbo limit, not a typical gaming draw. Arrow Lake desktop parts in this set do not use hyper-threading.
Memory in this table is DDR5.
The GeForce RTX 5060 row is the small-card case: the CPU and the platform are a large share of the total. The GeForce RTX 5090 row is the flagship case: the graphics card dominates, and the CPU's base-versus-limit gap matters less until you render on every core.
