What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Start with the exact GPU edition and the exact OEM chassis. Four NVIDIA RTX PRO 6000 Blackwell Max-Q Workstation Edition cards represent 1,200 W of GPU board power (4 × 300 W). Four standard RTX PRO 6000 Blackwell Workstation Edition cards represent 2,400 W (4 × 600 W). Those are GPU-only specification subtotals, not measurements of a complete workstation at the wall, and they are not sufficient by themselves to select a power supply, branch circuit, or UPS.
The practical planning sequence is to lock the card variant, obtain the quoted system’s maximum input and PSU details, validate sustained cooling under the intended workload, and then verify card spacing, service clearances, rails, rack depth, and rack-unit height against the OEM’s drawing. NVIDIA documents a class of latest-generation OEM workstations that can carry four Max-Q cards and 384 GB of aggregate GPU memory, but that statement does not make every four-GPU model or configuration available.

What the four-GPU numbers actually tell you
GPU board power is the only quantified electrical figure established for these configurations. NVIDIA’s 2025 specifications list 300 W total board power for the RTX PRO 6000 Blackwell Max-Q Workstation Edition and 600 W for the standard RTX PRO 6000 Blackwell Workstation Edition. Multiplying by four gives the planning subtotals below.
| Configuration | Per-card board power | Four-card GPU subtotal | Cooling description | Card memory | What is established |
|---|---|---|---|---|---|
| RTX PRO 6000 Blackwell Max-Q Workstation Edition | 300 W | 1,200 W | Active-cooled | 96 GB GDDR7 ECC | NVIDIA presents this edition as scalable to four GPUs in an OEM workstation class. |
| RTX PRO 6000 Blackwell Workstation Edition | 600 W | 2,400 W | Double-flow-through | Not stated in the supplied specifications | The 600 W figure is a per-card specification; a four-card system is not documented here as a universal OEM configuration. |
The 1,200 W and 2,400 W totals are arithmetic from NVIDIA’s per-card figures. They exclude the CPU, memory, storage, motherboard, fans, voltage-conversion losses, pumps if present, USB devices, and any other load. A workstation can therefore require a higher-rated power system than either subtotal, while its measured draw may vary with workload and power limits.

Step 1: freeze the GPU variant before doing any sizing
Put the exact edition on the quote
Do not write merely “four RTX PRO 6000 cards” in a purchase request. Specify “RTX PRO 6000 Blackwell Max-Q Workstation Edition” or “RTX PRO 6000 Blackwell Workstation Edition,” including the intended quantity. The two editions have different board-power targets and different thermal implementations. Substituting one after the electrical or mechanical design is complete can invalidate the calculation.
For the Max-Q option, NVIDIA lists a 300 W total board-power target, active cooling, a dual-slot form factor, and dimensions of 4.4 inches high by 10.5 inches long. NVIDIA also lists 96 GB of GDDR7 ECC memory per card. Four such cards provide 384 GB of aggregate GPU memory when all four are installed; this is an aggregate capacity, not a single shared memory pool.
The standard Workstation Edition is specified at 600 W per card and uses a double-flow-through cooling solution. Its physical and airflow requirements must come from the exact product documentation and OEM design; do not copy the Max-Q dimensions or assume the same spacing works.

NVIDIA’s 2025 solution brief describes latest-generation OEM RTX PRO AI workstations supporting up to four Max-Q GPUs. That is a category-level capability statement. It does not confirm that every vendor, chassis, processor choice, riser arrangement, or shipping configuration supports four cards simultaneously. Require the system supplier to identify the exact model, part numbers, slot population rules, and supported power configuration in writing.
Step 2: turn board power into a system electrical specification
Use the GPU subtotal only as the first line of the worksheet
Record the GPU calculation separately from the complete-system requirement:
GPU board-power subtotal = number of cards × rated board power per cardFor four Max-Q cards, the worksheet line is 4 × 300 W = 1,200 W. For four standard Workstation Edition cards, it is 4 × 600 W = 2,400 W. Label both lines “GPU board power only.” Do not relabel them as wall draw, PSU capacity, heat output, or circuit demand.
Request the figures that the card datasheet does not provide
Ask the OEM for a configuration-specific electrical sheet covering the exact CPU, memory population, storage devices, network adapters, fans, and GPU count. At minimum, obtain:

- Maximum system input power and the conditions used to define it.
- Installed PSU wattage, number of PSU modules, efficiency assumptions, and whether the system is single-feed or dual-feed.
- Redundancy behavior: the load that can be sustained after one PSU module or one input feed is unavailable.
- Input voltage and frequency range, inlet connector type, cable and receptacle requirements, and the manufacturer’s recommended facility supply.
- GPU auxiliary-power connector count, connector type, cable routing, and bend-clearance requirements.
- Power limits or firmware settings that affect sustained GPU consumption.
Only after these values are documented should facilities size the receptacles, branch circuits, distribution units, and UPS. A PSU nameplate is a component rating, not a promise that the workstation continuously draws that amount; conversely, a 1,200 W GPU subtotal is not evidence that a 1,200 W PSU is adequate.
Plan for operating modes, not one optimistic reading
Request separate values for idle, representative inference or training, and maximum supported load if the OEM publishes them. Ask whether the maximum is a short-duration peak or a sustained limit. Record the measurement point—AC input, DC output, or another point—because figures taken at different points are not directly interchangeable. If the supplier does not publish a value, mark it “not stated” and obtain an engineering estimate rather than filling the gap with the GPU subtotal.
Step 3: design cooling around the complete system
Why card-level cooling labels are not enough
“Active-cooled” for Max-Q and “double-flow-through” for the standard Workstation Edition describe the card’s thermal approach. They do not prove that a particular chassis can remove heat from four cards continuously. The motherboard layout, neighboring-slot spacing, inlet temperature, fan curve, CPU cooler, power supplies, and airflow impedance all affect sustained operation.
Almost all electrical input eventually becomes heat in the room, but no measured heat-output value for a particular four-GPU workstation is established here. Treat room cooling and rack heat-load calculations as system-level engineering tasks, not as a direct reuse of the GPU subtotal.
Questions for the system supplier
- What sustained GPU workload and power limit were used for the thermal validation?
- What inlet-temperature range is supported, and at what altitude or installation conditions?
- What clearance is required at the front, rear, top, and sides for unrestricted airflow and service?
- Which direction does air travel through the GPU, CPU, and PSU sections, and can hot exhaust recirculate into the intakes?
- What airflow rate or fan operating range is expected at four-card load?
- Can all four GPUs operate at their intended power limit continuously without thermal throttling?
- What alarms, shutdown thresholds, or firmware responses occur if inlet temperature or fan speed exceeds limits?
Get the answers for the quoted configuration, not for an empty chassis or a two-GPU model. If the OEM offers multiple CPU coolers, drive cages, or riser layouts, the thermal result may change with each selection.
Translate workstation heat into room and rack planning
Give the facilities team the OEM’s maximum AC input and thermal design information together. They can then determine whether the room’s HVAC capacity, rack cooling method, and hot-aisle or cold-aisle arrangement are suitable. Keep the exhaust path clear of the intake path, and leave the service clearances specified in the installation drawing. Do not infer a rack’s cooling capability from its external dimensions or from the fact that it accepts the chassis mechanically.
Step 4: verify enclosure, slot spacing, and rack fit
Check the GPU envelope and the actual slot map
NVIDIA lists the Max-Q card as 4.4 inches high, 10.5 inches long, and dual-slot. Four dual-slot cards consume eight slot positions in a simple count, but the physical design may require additional spacing for airflow, risers, connectors, or service access. Confirm the OEM’s supported slot map and whether all four cards can be installed with the selected CPU, memory, storage, and network options.

Match the chassis to the rack, not just the rack opening
An OEM tower may fit on a shelf but still be unsuitable for a dense rack because of weight, airflow direction, service access, or the absence of a secure mounting method. A rack-mounted system requires confirmation of rack-unit height, rail compatibility, minimum and maximum rack depth, rear-cable clearance, and the load rating of the rails and rack. NVIDIA’s card dimensions do not establish any of those complete-workstation measurements.
Ask for the chassis depth measured with the required front and rear components installed. Check whether the rear exhaust, power cords, network cables, and rail release mechanisms extend beyond the nominal depth. Verify that the rack door and rear door leave the airflow openings unobstructed. For a tower installation, document how the unit will be positioned, restrained, grounded, and serviced, and ensure its intake and exhaust are not blocked by the enclosure or nearby equipment.
Step 5: compare the two card paths on consistent axes
The sourced specifications support the following comparison. Performance, purchase price, and a particular vendor’s availability require separate, current system-specific documentation and are intentionally not inferred here.
| Planning axis | Max-Q Workstation Edition | Standard Workstation Edition |
|---|---|---|
| Per-card board power | 300 W | 600 W |
| Four-card GPU subtotal | 1,200 W | 2,400 W |
| Cooling description | Active-cooled | Double-flow-through |
| Published dimensions in the supplied specification | 4.4 in high; 10.5 in long; dual-slot | Not stated in the supplied specification |
| Published memory per card | 96 GB GDDR7 ECC | Not stated in the supplied specification |
| Four-card OEM capability statement | NVIDIA describes up to four cards and 384 GB aggregate GPU memory in a latest-generation OEM workstation class | Not established by the supplied OEM capability statement |
| System PSU, wall draw, circuit, UPS, rack height, and rack depth | Configuration-specific; obtain from the OEM | Configuration-specific; obtain from the OEM |
Choose the path only after the OEM confirms that the selected chassis, PSU, cooling system, and facility interface support the intended four-card configuration. The lower Max-Q board-power subtotal may simplify electrical and thermal planning, but it does not eliminate the need for system validation. The standard edition’s 2,400 W GPU subtotal demands especially careful review of PSU capacity, input voltage, circuit loading, and heat rejection.

Worked planning examples without inventing system measurements
Example A: four Max-Q cards
- Record four cards at 300 W each.
- Calculate the GPU-only subtotal:
4 × 300 W = 1,200 W. - Add separate OEM-provided maximums for the CPU, memory, storage, motherboard, fans, and conversion losses.
- Use the resulting system figure—not 1,200 W alone—to select PSU capacity and facility power.
- Use the OEM’s thermal validation and inlet-temperature limits to size rack and room cooling.
The only numerical conclusion supported before the OEM data arrives is the 1,200 W GPU board-power subtotal.
Example B: four standard Workstation Edition cards
- Record four cards at 600 W each.
- Calculate the GPU-only subtotal:
4 × 600 W = 2,400 W. - Obtain the exact chassis and PSU design, including connector allocation and redundancy behavior.
- Confirm that the electrical distribution can support the system’s documented maximum input at the installation voltage.
- Require sustained four-card thermal validation before approving the rack location.
Here too, 2,400 W is not a wall-power measurement or a complete workstation requirement.

Common planning mistakes and how to correct them
Calling the GPU subtotal the workstation’s wall draw
Problem: A four-card subtotal is copied into a facilities request as the complete load.
Free tools Windows power users keep installed
One-click scans. No signup required.
Correction: Keep GPU board power in its own worksheet section and obtain maximum AC input for the exact system.
Mixing editions in one calculation
Problem: A 300 W Max-Q power figure is combined with the standard card’s cooling or mechanical assumptions.
Correction: Build a separate bill of materials and thermal review for each edition; never substitute specifications across editions.
Assuming an eight-slot count guarantees fit
Problem: Four dual-slot cards are expected to fit because the arithmetic says eight slots.
Correction: Validate spacing, risers, connector bend radius, airflow, and service access on the OEM drawing.

Using a rack’s nominal depth as the chassis depth
Problem: Rear cabling, rails, or doors obstruct exhaust after installation.
Correction: Check the fully configured chassis depth and all front and rear clearances in the installation documentation.
Assuming a four-GPU capability statement applies to every model
Problem: A category-level statement is treated as proof that any current OEM configuration supports four cards.
Correction: Require the supplier to identify the exact model and confirm the four-card, PSU, cooling, and rack configuration in writing.
What to put in the final purchase specification
A useful request for quotation should name the GPU edition and count, the intended workload, the CPU and memory configuration, storage and network options, installation voltage, rack or tower placement, and the required operating environment. Require the supplier to return a configuration-specific maximum input, PSU and redundancy description, thermal limits, airflow and clearance diagram, card spacing, chassis dimensions, rails, and service procedures.
That documentation turns the 1,200 W or 2,400 W GPU arithmetic into an actionable design. Until it is supplied, the responsible answer to “How much power does a four-GPU workstation need?” is that the GPU board subtotal is known, while the complete electrical, cooling, UPS, and rack requirements remain specific to the quoted system.
