  • PCI Express 4.0 x8 interface connects to modern platforms

Entry-level workstation GPU for multi-display rigs

The PNY Quadro A400 ships with 4 GB of GDDR6 memory on a 64-bit bus and four mini-DisplayPort outputs. It plugs into a PCI Express 4.0 x8 slot and measures 162.56 mm long. The card draws all power from the slot, so no auxiliary cable is needed. Windows 10 and 11 64-bit are supported.

Steady throughput for CAD and signage workloads

Because the board relies solely on slot power, clock speeds stay within a tight thermal envelope during long renders or continuous video walls. The 64-bit memory interface limits peak bandwidth, so large textures or heavy compute queues will throttle sooner than on wider-bus cards. Fan noise remains low under constant load.

Check slot wiring and display adapters before buying

Your motherboard must wire the PCIe slot for at least x8 electrical lanes to avoid a bottleneck. The 300 W minimum power supply rating assumes a typical system; verify your unit can deliver that headroom. Four mini-DisplayPort cables or active adapters are required to drive four monitors.

Spurningar um þessa vöru

Does the 300 W minimum power supply keep the A400 cool and quiet during all-day workloads?

The card draws power only from the PCI Express 4.0 x8 slot, so it has no extra power connectors; a 300 W system supply is the stated minimum and the 162.56 mm length fits most chassis airflow.

What cables or adapters do I need to use the four mini-DisplayPort outputs right away?

Four mini-DisplayPort connectors are built in; you will need mini-DisplayPort to DisplayPort cables or adapters for each monitor you plan to attach.

Will the PCI Express 4.0 x8 interface work on my older motherboard that only has PCIe 3.0 slots?

The card is compatible with PCI Express 4.0 x8 and will operate in a PCIe 3.0 x8 or x16 slot at the lower generation speed.
