Cited, not measured on the local desktop

Board power and PSU on Radeon

This page is electrical, not a tok/s card. Tokens still start on llama.cpp. Board power is AMD’s published TBP on the product page. A PSU minimum is only printed when AMD published one. Empty cells stay not recorded. We do not add headroom watts, dual-card SKUs, or street prices.

How we test — Measured cells cite official amdai-bench/run@1 cards. Estimates stay labeled. Q3 is estimate-only. Q1/Q2 stay off.

Cited board power

AMD-published TBP. Source links go to the product page. Sheet links stay on AMDai.

PSU sizing

  1. Step 1

    Read AMD’s TBP on the product page

    Total board power is the published electrical envelope for that SKU. The cited cells on this page copy AMD product pages already used on Radeon vs NVIDIA. If the cell is not recorded, open the product page for the card you are buying. Do not copy a neighbor SKU.

  2. Step 2

    Read AMD’s minimum PSU only when they published one

    AMD publishes a 750 W minimum PSU recommendation for the R9700 (product page). That is a generic-system minimum, not headroom for a 5090-class CPU and six drives. Other directory cards stay not recorded — check the product page for the SKU you buy.

  3. Step 3

    Do not invent headroom watts

    AMDai does not add a house formula on top of TBP. 1000W-class is search guidance for headroom, not a SKU and not a dual-card rating. Buttons say Check price — we do not print a figure.

  4. Step 4

    Use a native 12V-2x6 cable if that is what the card expects

    The R9700 product page lists a 12V-2x6 connector. Cheap pigtails are how people learn about transient spikes. Match the connector the card actually has. We do not invent a pinout for partner coolers.

  5. Step 5

    Two R9700s are not a PSU SKU we invent

    AMD publishes 300 W TBP and a 750 W minimum PSU recommendation per R9700 (product page). Two 300 W TBP cards plus 750 W minimum per card is not a dual-card PSU number we will invent. Check the unit you buy. A second card on the local desktop is copies or Flash offload, not automatic 2× decode. llama.cpp first.

  6. Step 6

    Then get a token on llama.cpp

    Power is settled before you chase tok/s. Ubuntu 24.04+ is the measured first-run path. Size the GGUF on the calculator. Q3 stays a labeled estimate when a quant comparison appears. Q1/Q2 stay off.

1000W-class PSU

AMD’s R9700 minimum recommendation is 750 W. A 1000W-class unit is search guidance for headroom, not a SKU. Budget tiers now name an 850 W or 1200 W unit instead.

AMD Radeon AI PRO R9700

Newegg's R9700 offers have been marketplace sellers (checked 2026-10-30), so that seller's return policy applies, not Newegg's. Open the listing's Warranty & Returns tab before you buy.

Dual R9700

The local desktop seats two Radeon AI PRO R9700 cards. AMD publishes 300 W TBP and a 750 W minimum PSU recommendation per card (product page). That is electrical, not a street price. Two 300 W TBP cards plus 750 W minimum per card is not a dual-card PSU SKU we will invent. 1000W-class is search guidance, not a SKU. Check the unit you buy; use a native 12V-2x6 cable if that is what the card expects. A second card is copies or Flash RAM offload, not automatic 2× decode. Minimum system RAM needed and RAM needed at full context for that Flash job live on the Flash RAM offload page — this page does not invent a kit size. llama.cpp first.

Minimum system RAM needed and RAM needed at full context for Flash offload: /flash-ram-offload. This page does not invent a kit.

FAQ

  • What is TBP?

    Total board power. AMD publishes it on the product page for the SKU. The cited rows here copy those pages. It is not a measured wall-plug number from local desktop and not a street price.

  • What PSU does one R9700 need?

    AMD’s published minimum is 750 W, and TBP is 300 W (product page). That is a generic-system minimum. If your PSU is below 750 W, upgrade the PSU — do not guess a wattage. 1000W-class is search guidance for headroom, not a SKU.

  • What PSU do two R9700s need?

    Two 300 W TBP cards plus 750 W minimum per card is not a dual-card PSU number AMDai will invent. Check the unit you buy. 1000W-class stays search guidance. See Dual / multi-GPU for when the second card helps.

  • Where is TBP for the 16 GB cards?

    Not recorded on AMDai yet. The RX 9070 XT, 9060 XT, 7900 GRE, 7700 XT, 7600 XT, and 7600 sheets do not invent a wattage. Open the product page for the SKU you buy. Strix Halo is a shared-memory APU — no discrete TBP is cited here.
