Half height graphics cards, usually sold as low profile cards, exist for one reason: to fit where normal cards won’t. Dell OptiPlex SFF, HP ProDesk SFF, Lenovo ThinkCentre SFF, and cheap HTPC cases all need them. The trade-off is you get less cooler, less power headroom, and fewer good options than the full-size market.
If you buy right, a half height card can turn a $150 office PC into a solid 1081080p esports machine or quiet media PC. If you buy wrong, you get a card that doesn’t fit, won’t boot, or gets starved by a 180W proprietary PSU. Here’s how to avoid that.

Top 3 picks at a glance
What to check before you buy
Half height does not mean single slot. Almost every useful low profile card is dual-slot tall at the cooler, but comes with a short bracket. Check both: bracket height and cooler thickness. Many SFF Dells only accept dual-slot low profile cards up to about 6.6 inches long. Measure from the back bracket to the drive cage or PSU.
Power is the second killer. Most true half height cards are 50-75W and run on PCIe slot power only. That’s what you want for a prebuilt with no 6-pin cable. Anything that needs a 6-pin, like some GTX 1650 low profile variants and most RTX A2000 cards, will not work in a stock 240W-300W office PSU without an adapter, and adapters on proprietary Dell/HP 12V rails are a bad idea.
Third, check video outputs and UEFI. Older cards like the GT 710/GT 1030 often have VGA + HDMI + DVI, which is handy for old office monitors. Newer cards like the RX 6400 low profile are DisplayPort + HDMI only and require UEFI boot. On a 2013-era OptiPlex in Legacy mode, an RX 6400 may not post. For Haswell and older machines, a GTX 1050 Ti or GTX 1650 is safer.
Half height options compared
This is the short list worth buying in 2026. Everything else is either too old, too cut down, or priced like a collector’s item.
| Card type | Power | Best for | Limitations |
|---|---|---|---|
| RX 6400 low profile | 53W, no 6-pin | Esports 1080p, modern SFF with UEFI | Only x4 PCIe lanes, weak on PCIe 3.0, no AV1 encode |
| GTX 1650 low profile | 75W, usually no 6-pin | Older office PCs, best driver compatibility | Price inflated, GDDR5 vs GDDR6 lottery, no AV1 |
| GTX 1050 Ti low profile | 75W, no 6-pin | Cheap upgrade for Haswell/Ivy Bridge systems | Used only, aging, ~30% slower than GTX 1650 |
| Arc A310 low profile | 75W, no 6-pin | HTPC, AV1 encode/decode, 4K video | Needs Resizable BAR, weak drivers on old systems |
| GT 1030 / RX 550 low profile | 30-50W, no 6-pin | Video out, 4K desktop, very weak PSUs | Not for gaming beyond esports low settings |
Best all-around gaming pick: GTX 1650 low profile
If your goal is gaming on a SFF office PC, the low profile GTX 1650 is still the safest buy. It pulls all power from the slot on most models, works in both Legacy BIOS and UEFI, and NVIDIA’s drivers still behave on Windows 10/11 with old Intel chipsets. Expect 60+ fps in Valorant, CS2, Fortnite Performance Mode, and League at 1080p medium, and 40-60 fps in GTA V and Elden Ring at 1080p low-medium.
The failure mode here is price and variants. There are GDDR5 and GDDR6 versions, single-fan and dual-fan, and some with a 6-pin that you do not want for a stock Dell/HP. Look specifically for a dual-fan, slot-powered version with a low profile bracket in the box. A low profile GTX 1650 normally costs more than a full-size one, so don’t pay RTX 3050 money for it. If the price is over $190 new, buy used or drop to an RX 6400.
Who should skip it: if you have a modern system with ReBAR and PCIe 4.0 and only play esports titles, the RX 6400 is usually cheaper and slightly faster while running cooler.
Best value for modern PCs: RX 6400 low profile
The RX 6400 low profile is the only new AMD half height card that makes sense for gaming. At 53W it will run in almost anything, it stays quiet because the cooler is oversized for the chip, and single-fan models are genuinely short enough for Lenovo Tiny-adjacent SFF cases.
The catch is PCIe lanes. It only uses 4 lanes. On PCIe 4.0 that’s fine and it trades blows with the GTX 1650. On PCIe 3.0, common on 6th-9th Gen Intel office PCs, you lose 10-15% in many games and get stutter in open-world titles. It also has no hardware AV1 encoding, which matters if you stream or record.
Buy it if you have a Ryzen 3000 or newer, or Intel 10th Gen or newer SFF, and you want new-with-warranty. Check current listings for a RX 6400 low profile with two DisplayPorts if you run dual monitors. If you are upgrading a 2014 OptiPlex 3020, don’t. Get a used GTX 1050 Ti instead.
Best for HTPC and video: Arc A310 or GT 1030
For a living-room PC that never games, don’t buy gaming performance. Buy decode, power draw, and noise. The Intel Arc A310 low profile is excellent here: full AV1 decode and encode, HDMI 2.1, quiet fans, and 75W slot power. It handles Plex, Jellyfin, YouTube 4K, and light Premiere work far better than a GTX 1650.
But it needs Resizable BAR enabled to perform normally, and Intel’s drivers expect Windows 10 21H2 or newer plus UEFI. On an old Haswell HTPC, you will get crashes or Code 43 errors. In that case the cheaper option is honestly fine: a DDR5 version of the GT 1030. Avoid the DDR4 version, it’s about 40% slower for the same money and stutters even in Rocket League.
For silent 4K desktop use in 180W micro systems, shop for a low profile GT 1030 GDDR5 fanless model. No gaming expectations, just video outputs and 30W heat. Anything more is wasted money and fan noise.
What about used and workstation cards?
Used GTX 1050 Ti low profile cards are the budget king for old prebuilts, usually $70-$100. They don’t need external power, they boot in anything, and the 4GB VRAM is enough for esports. Inspect fan condition – these small 40-50mm fans develop bearing rattle after 4-5 years, and replacements are proprietary. If the seller photo shows dust packed in the heatsink, pass.
RTX A2000 low profile cards show up used and look tempting, but most need a 6-pin and a 300W+ PSU, plus they are 2.5 years of mining risk. They are also louder in SFF cases because they exhaust heat inside. Unless you need CUDA for Blender or Stable Diffusion in a SFF workstation, skip them for gaming.
FAQ
Will a half height card fit my Dell OptiPlex SFF?
Usually yes if it’s listed as low profile and under 6.7 inches long, but you must swap to the short bracket and you must have two slots free at the back. The OptiPlex 7010/7020/9020 SFF and 3050/3060/3070 SFF all accept dual-slot low profile 75W cards. The Micro (MFF) models accept no graphics card at all.
Do I need to upgrade my power supply?
For 30W-75W slot-powered cards, no. A stock 240W-300W Dell or HP PSU can run an RX 6400, GTX 1650, or GT 1030. If your card has a 6-pin connector, stop and check your PSU cables. Most SFF office PSUs don’t have one, and SATA-to-6-pin adapters can melt under sustained load.
Is the RX 6400 or GTX 1650 better for an old PC?
For PCIe 3.0 and Legacy BIOS systems, get the GTX 1650. The RX 6400 loses performance on PCIe 3.0 x4 and may not boot without UEFI. For PCIe 4.0 systems with UEFI, the RX 6400 is usually cheaper, newer, and runs cooler for the same fps.
Can I game on a GT 1030 in 2026?
Only esports at 720p-1080p low. It will do League, Valorant, CS2, and Minecraft at 60 fps with turned-down settings, but modern AAA games will be 20-30 fps even at low. Buy it for video output and acceleration, not as a gaming card. If gaming matters, save for a used GTX 1050 Ti or new RX 6400.
