Does the Stormcraft Sirius include a graphics card?

The listed specs name only the i5-14400F, which has no integrated graphics, so a dedicated GPU must be present for the PC to display anything. Confirm the exact GPU model with the seller before buying.

Can I upgrade the CPU later?

Yes. The B760 board supports Intel's 12th, 13th and 14th Gen Core processors on the LGA 1700 socket, so a faster chip from those generations is a drop-in upgrade after a BIOS check.

Is the power supply enough for a better GPU?

A 650W 80 Plus Gold unit comfortably covers mid-range cards. Very power-hungry flagship cards would be pushing it, so match any upgrade to the PSU's wattage and connectors.

How does it compare with the i5-13400F version?

The 14400F is a mild refresh of the 13400F with slightly higher clocks. Expect a small performance gain, not a generational leap, so either is fine if the rest of the build matches.

Typically the tower, a power cable and Windows 11 Home preinstalled. Keyboard, mouse and monitor are usually not included, so check the listing before ordering.
