HP Pro Tower 400 G9 — GPU compatibility and local LLM capability

Tower (mini tower) · released 2022 · also listed as HP Pro Tower 400 G9 Desktop PC, HP Pro 400 G9, HP ProDesk 400 G9 (naming used for the preceding generation) · last updated 2026-09-24

102 of 208 graphics cards with a recorded verdict for this machine are marked ✓ Fits (0) or △ Fits with conditions (102).

208 cards have been assessed against the published specifications of the HP Pro Tower 400 G9: 102 fit with conditions, 4 do not fit and 102 are unverified. Conditions most often concern card length (102 cards) and card width (102); the manufacturer publishes no maximum card length and no slot-width ceiling for this machine. Of the 4 cards that do not fit, all 4 conflict with this machine's largest supply option. The longest fitting card is the Intel Arc B580 (Reference design) at 272 mm; the highest board power among them is 200 W (NVIDIA RTX A4500). The most card memory reachable through a fitting card is 20 GB (NVIDIA RTX 4000 SFF Ada Generation and 1 other). The largest listed model that memory holds at 32k context is Gemma 3 27B (Q4_0 (QAT), 20.0 GiB).

Card-by-card verdicts Local models Full specifications Evidence and sources

What this page answers: which graphics cards the published specifications of the HP Pro Tower 400 G9 accept, what conditions each verdict carries, and how much of a local language model the resulting card memory holds.

We have not physically tested this combination. Data is compiled from official specification sheets and cited sources. A verdict says what the specifications imply, not what happened when someone tried it.

Which graphics cards fit

Conditions shared by the cards below. Each is stated once here. They come from this machine's own records, or are worded the same for more than one card. A row in the table names the ones it carries by number and adds only what is particular to that card.

Card length: the manufacturer does not publish a maximum card length for this machine. Measure the clearance in front of the slot and compare it with the length of the card. (204 rows)
Card width: the slot-width figure used for this machine is recorded here from material whose source the record does not identify, not from a ceiling the manufacturer publishes. Check that there is room beside the x16 slot. (12 rows)
Card width: the manufacturer offers a 2-slot card as a factory option for this model, so a card no thicker than 2 slots is established as going in. That is a floor rather than a published ceiling: it settles such a card and says nothing about a thicker one. (96 rows)
Card width: the slot-width figure used for this machine is recorded here from third-party or community material, not from a ceiling the manufacturer publishes. Check that there is room beside the x16 slot. (23 rows)
Card width: the manufacturer publishes no slot-width ceiling for this machine. Check that there is room beside the x16 slot for the width of the card. (23 rows)
Card width: the maker does offer a 2-slot card as a factory option for this machine, which is a floor rather than a published ceiling. (11 rows)
Power: the supply rating used for this machine is recorded here from material whose source the record does not identify, not from a specification the manufacturer publishes for this machine. Read the rating off the label on the supply in the machine you own. (9 rows)
Power: the supply rating used for this machine is recorded here from third-party or community material, not from a specification the manufacturer publishes for this machine. Read the rating off the label on the supply in the machine you own. (17 rows)
Power: this machine's supply options are 180 W, 260 W, 400 W. (147 rows)
Power: a card vendor's recommended system supply covers the whole machine and carries the vendor's own margin, so judge it against the configuration you own. (109 rows)
Power: where a row says the card's vendor publishes no recommended system power, it cannot be set against this machine's supply. Check the card's own specification sheet. (38 rows)
Power: the largest supply option for this machine is 400 W. (4 rows)
Auxiliary power connector: what this machine's supply offers is recorded here from third-party or community material, not from a specification the manufacturer publishes. Open the machine and look at the cable before buying. (14 rows)
Auxiliary power connector: the manufacturer does not publish what this machine's supply offers a graphics card. Where a card needs a connector, open the machine and look at the cable before buying. (158 rows)
Auxiliary power connector: what this machine's supply offers is recorded here from material whose source the record does not identify, not from a specification the manufacturer publishes. Open the machine and look at the cable before buying. (1 row)

Only cards with a recorded verdict appear above. This machine has a verdict for 208 of the 242 cards in this database; the remaining 34 have not been assessed against it, which is not the same as them being ruled out.

What each verdict means. Every one of them is a statement about published specifications.
Verdict	Meaning
✓ Fits	Published specifications show no physical or electrical conflict.
△ Fits with conditions	Published specifications allow it only under the stated conditions.
✕ Does not fit	Published specifications rule the combination out: the card needs a connector the machine does not have, draws more than the supply provides, or is physically too large. It is a statement about specifications, not a report of a failed attempt.
? Unverified	There is not enough evidence to say.

Fitting cards with a published memory size, by memory. A row above that ends with “N other fitting cards with X GB or more” means every card in this list at X GB or above gives that outcome.

These figures are calculated from the published size of the distributed quantised file and the model architecture, under the assumptions set out in the memory sizing rule. Exceeds VRAM does not mean the model will not run: inference software can keep part of a model in system memory. How fast that is, and whether it is pleasant to use, is outside what this site measures.

Specifications

Manufacturer and model: HP HP Pro Tower 400 G9
Product line: HP Pro Tower
Form factor: Tower (mini tower)
Processor generations: Intel Core 12th, 13th and 14th generation i3/i5/i7/i9 (Alder Lake / Raptor Lake / Raptor Lake Refresh, LGA1700)
Power supply ratings offered: 180 W / 260 W / 400 W · A read 2026-07-20 [S1]
Standard ATX supply: No — the unit is proprietary, so it cannot be replaced with a retail ATX supply
Auxiliary power for a graphics card: PCIe 2x4 (only when an RTX 3050 is fitted; requires the 400 W power supply) · A read 2026-07-20 [S1]
PCIe x16-form slots: 1, PCIe generation 4 (Generation 4 (inferred from the processor generation; not stated in the QuickSpecs))
Other slots: One PCIe x1 slot (one free) and one PCI slot (one free)
Maximum card length: Not stated by the manufacturer
Maximum card width stated by the manufacturer: Not stated by the manufacturer
Card width known to have been fitted: 2 slots — the manufacturer offers a card that wide as a factory option. This is a floor, not a ceiling: a wider card is not ruled out by it · B read 2026-07-20 [S1]
Low-profile bracket only: No · A read 2026-07-20 [S1]

Each graded figure above cites: [S1] HP Pro Series 400 G9 Desktops PCs QuickSpecs (doc: c08017709, Version 27, May 2026) (manufacturer document held by the operator; no stable public link).

What the documents say, and what they leave out

A proprietary form factor (165 x 95 x 73 mm). The Japanese-market build-to-order configuration ships with the 260 W Platinum unit as standard; the 400 W unit is mandatory when an RTX 3050 is fitted.
180W=80PLUS Gold / 260W=80PLUS Platinum / 400W=80PLUS Platinum
Not stated in the material available. A cable may be included when an RTX 3050 is fitted, but the part number is unconfirmed.
Largest card known to have been fitted: RTX 3050 (ATX dual slot, 144.7 x 111.15 x 36.70 mm, 120 W). The QuickSpecs state no maximum clearance as a figure.

Before you buy

Power. Leave headroom; OEM PSUs are often rated at the limit. The ratings above are what the manufacturer publishes for the supply, not a measurement of what this particular unit delivers after years of service.

Auxiliary power. Where a card needs a 6-pin or 8-pin connector, the machine must actually have that cable. A supply of adequate wattage with no auxiliary cable does not power such a card.

Clearance. Card length, width in slots and bracket height are three separate limits. A card can clear one and fail another.

Individual units vary. Prior owners replace supplies, case revisions change clearances, and firmware versions differ. Verify with the manufacturer before purchasing.

The same manufacturer and chassis, so the clearance and supply constraints are of the same kind. The figures still differ per model.

Evidence behind each verdict

Each verdict rests on this machine's own documents, listed once below, and on the graphics card's specification, listed per card with the date it was read. The conditions behind each verdict are in the table above.

Unless a line below says otherwise:

each card document is of the kind “near-primary”;
each document was used as follows: Derived from published specifications;
what each entry says is note [T1] below.

[T1] Derived mechanically from the published figures in the document cited here. What those figures rule in or out is set out in the conditions for this row. (202 entries below)
[T2] Source consulted for this row. The original assessment has been superseded by the coverage check (see conditions); the published values from this source are reflected in the specification fields. (192 entries below)
[T3] Source consulted for this row. The reasoning originally given for the verdict was withdrawn by the coverage review; the items left unconfirmed are listed in the conditions. The published values from this source are reflected in the specification fields. (8 entries below)
