NVIDIA RTX PRO cards in Dell, HP and Lenovo workstations by the makers' own lists

Which RTX PRO card fits a Dell, HP or Lenovo workstation

Whether an NVIDIA RTX PRO card fits a Dell, HP or Lenovo workstation is settled by the maker's own option list for that model and by its power supply. Dell's manuals for the Dell Pro Precision 9 T2, T4 and T6 list the RTX PRO 2000, 4000, 4500 and 5000 Blackwell. HP's QuickSpecs for the HP Z2 Tower G1i excludes the RTX PRO 4500 with the 500 W supply and the RTX PRO 5000 with the 500 W and 700 W supplies, and Lenovo's PSREF lists the same cards for the ThinkStation P3 Tower Gen 2 beside supplies of 500, 750 and 1100 W.

We supply the cards. We do not supply or service the Dell, HP and Lenovo workstations themselves, so the tables below are the makers' option lists as read on 12 November 2026 and not an offer of ours.

Each maker keeps the list in a different document. Dell prints it in the Owner's Manual or the "Setup and Specifications" of a model, as names with memory size and nothing else. HP prints it in the QuickSpecs, with a column for the supported number of cards and footnotes on the power supply. Lenovo prints it in the PSREF, the product specifications reference, with a power figure and a slot width per card and one or two sentences that begin "Supports up to". Dell's manuals, HP's QuickSpecs and Lenovo's PSREF write "RTX PRO 4500 Blackwell" without the edition. Dell's configurator adds "Workstation Edition (200W)" and Lenovo's PSREF prints 200 W beside the name, the board power of the actively cooled NVIDIA RTX PRO 4500 Blackwell Workstation Edition; that card is meant wherever this page writes RTX PRO 4500, and the passive Server Edition is in none of the lists we read. The names on the makers' pages today are Dell Pro Max and Dell Pro Precision, HP Z2 Tower G1i, Z2 SFF G1i, Z4 G6i and Z8 Fury G6i, and Lenovo ThinkStation P2 Tower Gen 2, P3 Tower Gen 2, P3 Ultra SFF G2 and P5 Gen 2.

Dell Pro Max and Dell Pro Precision in the manuals and the configurator

Dell's manuals on its support site for the six models (in table order Dell Pro Max Tower T2 FCT2250, Pro Precision 9 T2 PW9T2260, 9 T4 PW9T4260, 9 T6 PW9T6260, Precision 5860 Tower, Dell Pro Max Slim FCS1250), read 12 November 2026. Cards of other lines in these lists (A800 40 GB, T400, T1000) are left out.

Dell's lists carry no column for power, slot width or count.

For the Dell Pro Max Tower T2 the manual and the shop disagree. Revision A08 of the manual lists two Blackwell cards. Dell's US configurator, read the same day, offers in addition the RTX PRO 2000, the RTX PRO 4000, the RTX PRO 5000 with 72 GB and the 600 W RTX PRO 6000 Workstation Edition, together with a 750 W supply that the manual does not have. We report both and do not merge them.

A card count is stated in none of the manuals. In the configurator of the Dell Pro Precision 9 T2, "Dual" is offered for the RTX A400, the RTX A1000, the RTX PRO 2000, 4000, 4500 and 5000 and the RTX PRO 6000 Max-Q, "Triple" for the RTX A1000 and the RTX PRO 4000, and the 600 W card as one card only. For the Dell Pro Max Tower T2 "Dual" is offered only for the RTX A400, the RTX A1000 and the RTX PRO 2000. For the 9 T6, Dell's blog of 26 March 2026 states "support for 2× 600W or up to 5× 300W NVIDIA RTX PRO Blackwell GPUs". A configurator is a sales page, which is why we write "offers".

Dell names the graphics power leads by pin count. The 9 T2 has one 8-pin lead with the 500 W supply, one 6-pin and one 8-pin with 750 W, and two of each with 1500 W; the Precision 5860 Tower has two 8-pin (6+2) leads with 750 W and four with 1350 W. No Dell page we read names a 16-pin connector or says which adapter comes with a 16-pin card. The 1500 W supply of the 9 T2 gives its full rating at 180 to 264 V and 1,200 W at 115 to 179 V. The Dell Pro Max Slim has half-height slots only, and its manual warns that a discrete graphics card installed without the front chassis fan causes a BIOS error.

HP Z2 Tower G1i in the QuickSpecs, with HP's power-supply notes

HP QuickSpecs for the HP Z2 Tower G1i, document c09133728, Worldwide, Version 25, 19 August 2026, column "Support Notes"; read 12 November 2026 in a copy of the document, not on HP's own document server, where a newer version may exist. The list also has the RTX 5880 Ada and RTX 6000 Ada, both not with the 500 W and 700 W supplies. The column for the supported number of cards is not reproduced here: read it in HP's document.

The QuickSpecs lists supplies of 1200, 700 and 500 W with 92 per cent efficiency and states: "1200W and 700W configurations support a 12VHPWR graphics power connector; 500W supports a 6+2 pin graphics power adapter." Slot 1 is PCIe Gen5 x16; slot 3 has x16 size and four Gen4 lanes. For a card that the customer installs HP writes: "If the customer is installing their own 8-pin/12-pin graphics card, we recommend using the HP Graphics Cable Kit (B5CJ4AA), which includes necessary converters." Its general note says that additional third-party graphics cards may be available and refers to the sales representative or channel partner for information.

For the other current HP models we read product pages only, and those name the largest card, not the list.

HP's product pages for the three models, read 12 November 2026. The full lists are in the QuickSpecs of the three models (c09133725, c09249983 and c09249982), which this table does not reproduce.

Lenovo ThinkStation P2, P3 and P5 in the PSREF

Lenovo PSREF, ThinkStation book, Version 670 (cover 9 September 2026, page footers 2 September 2026) and the PSREF sheet of the ThinkStation P5 Gen 2 (2 September 2026), read 12 November 2026. The T1000 in the list of the P3 Ultra SFF G2 is left out.

Lenovo's "Supports up to" sentences name one or two example cards and are no rule for every card on the list. The PSREF prints 140 W for the RTX PRO 4000 Blackwell, while NVIDIA's datasheet gives 145 W. In the ThinkStation P2 Tower Gen 2, slot 1 is PCIe 5.0 x16, full height and double-width, with 75 W from the slot and room for a card of 268 mm or less.

For the ThinkStation P3 Tower Gen 2, Lenovo publishes a Power Configurator (Version 1.3, August 2026). Its columns are headed "1100W (12VHPWR)", "750W (2x PCIe 6+2)" and "500W (PCIe 6+2)". The 600 W RTX PRO 6000 Workstation Edition is, in Lenovo's words, "only supported with 1100W PSU in the updated P3 Tower Gen 2 chassis", and it requires a BIOS option that adapts the chassis cooling: "The system BIOS version must be at least S0MKT14A for this setting to appear." Two more sentences matter for an upgrade: "Graphics cards should not be mixed in dual-GPU configs." and "Non-Lenovo (3rd Party) versions of these cards are not officially supported due to mechanical differences.", the latter about the 600 W card and Lenovo's own RTX 5090. Lenovo names two adapters, a "12VHPWR (female) to dual 6+2-pin Power Cable Adapter" (FRU 5C10U58750) and an "8-pin (female) to 12VHPWR (male) Power Cable Adapter" (FRU 5C10U58794).

The PSREF sheets of the larger ThinkStation P7, P8 and PX, dated September and October 2026, list the Blackwell cards next to RTX A-series cards; our upgrade map for RTX A-series cards starts from those.

We supply the RTX PRO Blackwell and RTX Ada cards named in these lists, and the RTX A1000 and RTX A400, across the EU; send us the workstation model, its power supply and the number of machines, and we reply with a written quote within one business day.

The 16-pin connector under three names

NVIDIA's datasheets call the power connector of the larger cards PCIe CEM5 16-pin. HP and Lenovo write 12VHPWR, and Dell's manuals name only 6-pin and 8-pin leads. NVIDIA's quick start guides list an adapter in the box: from one 8-pin PCIe cable for the RTX PRO 4000 Blackwell, from two for the other 16-pin cards in the table. Since the makers' lists mostly omit power and connector, the table gives NVIDIA's figures for the cards of ours that appear in them.

NVIDIA datasheets of the ten cards (dates between August 2023 and June 2026) and NVIDIA's quick start guides for the RTX PRO Blackwell and the RTX Ada cards. The five cards up to 70 W are 2.7 in high, the others 4.4 in.

NVIDIA publishes no power-supply wattage for any of these cards. Rules such as HP's two notes and Lenovo's 1100 W condition are the workstation makers' rules. Our article on RTX power connectors and power supplies goes through the connectors card by card.

Slot width and card length

Only one document we read states a length. Lenovo's 268 mm for slot 1 of the ThinkStation P2 Tower Gen 2 is 10.55 in by our conversion, and NVIDIA's dual-slot cards in the table are 10.5 in long. Dell's pages publish no length limit, and no maker document we read gives a general maximum. Slot width is clearer: Lenovo marks slot 1 of the P2 and P3 towers as double-width, and its only two-card sentence for these towers names the RTX 2000 Ada.

For the small-form-factor machines the lists name the 2.7 in cards. The Dell Pro Max Slim has half-height slots only, HP describes the graphics of the Z2 SFF G1i as low-profile, and the ThinkStation P3 Ultra SFF G2 lists the RTX PRO 2000 Blackwell. Our pages on low-profile NVIDIA RTX cards and single-slot NVIDIA RTX cards sort the cards by format.

Upgrading the GPU of a workstation that is not on a list

No maker document we read supports the statement that a card fits a workstation on whose list it does not stand. Before a card is ordered for such a machine, five points are worth checking.

1. The current revision of the maker's list. Dell's manual for the Precision 5860 Tower added the Blackwell cards in revision A05 of March 2026 and the RTX PRO 2000 in A07 of August 2026, so an older copy lacks them.
2. The rating of the installed power supply and the conditions the maker attaches to it, as in HP's notes and Lenovo's configurator.
3. The power leads: a 16-pin cable, or the 8-pin PCIe leads that NVIDIA's adapter needs, or the maker's own adapter kit.
4. Slot width, slot height and free length behind the slot.
5. The BIOS level and the maker's support statement. Lenovo recommends the latest BIOS; HP refers to its sales channel for third-party cards; the support-policy topic of Dell's manuals points to Dell's support site and says nothing on cards outside the list.

We read no warranty sentence on cards from other sources in any of the three makers' documents, so a machine under a service contract is a question for the maker's support. Where no listed machine fits the task, we build workstations to order, and the builds by task are in our GPU workstation builds guide.

For the request it helps to state the workstation model with its code, the power supply and the card that is in the machine today; write to us with these three facts and the quantity, and configuration and compatibility are confirmed before the quote. Card names and editions are explained in what to state in a quote, fleets of identical PCs in the RTX PRO 2000 Blackwell fleet rollout, and all cards from 4 to 48 GB in the NVIDIA RTX workstation GPU guide.
