Sapphire PULSE RX6400, 4GB DDR6, PCIe4, HDMI, DP, 2321MHz Clock, Low Profile (Bracket Included)

If you have a small form factor/mini desktop PC and want to add a GPU to beef up its graphics capability there are very few graphics card options that will fit in the tight space available. Luckily this low profile RX 6400 card is readily available for a reasonable price and will readily fit in most SFF cases that have a single free PCI slot. Sure, the RX 6400 might not perform very well when compared against better specified, bigger, much pricier cards but since installing (very easily) this card in my DeskMini AMD Ryzen 5 5600g I’ve had no problems playing Red Dead Redemption 2 at 1080P with medium settings - that’s good enough performance for me, especially at the price paid for the card. I reckon the RX 6400 has at least doubled the performance of the CPU’s integrated Vega graphics I was relying on before, for a little over 100 pounds paid. Highly recommended for the right use case (mini/small case PCs with no GPU and a suitable motherboard with a PCI slot), but don’t expect it to be able to play more recent AAA games smoothly - it’s not a graphics powerhouse.

Did exactly what I was hoping. Bought it to go into a Dell optiplex 7010 i7 SFF specifically to play World of Warcraft. Fitting was simple. Downloading drivers no problems. And it has significantly improved the performance. Went from low settings avg 15fps (with standard Intel hd4000 on board graphics) to max settings steady 45fps which is more improvement than I expected. Would recommend for anyone wanting a little more out of a sff Dell. Note: card says minimum 350w power supply. The Dell I've got it in has 249w power supply and am having no issues but results may vary on that.

It fits my Acer 1780 XC and works fine (although I did need to beef the power supply to 300W). Really happy with it except it doesn't come with a retaining screw - a really odd and irritating omission. It means you're going to need to add a few quid to the price to pay for a pack of screws, nearly all of which you won't need. As I say, oddly irritating, when Sapphire could easily bundle a single one with all of the other bits and pieces.

A good price by performance value graphics card. Easily fitted inside my Dell Optiplex 7020 SFF DESKTOP computer in a single slot. The performance is not bad considering this GPU is now getting old but I got 60FPS on most of the modern games as well 1080p with Maximum settings.

Hi, I've been using this card on my mini pc for the last 40 30 days with an extra fan on GPU and still it went to 101 celsiuc degree when doing simple tasks not gaming!!! Can't recommend! Stay away from RX6400. Thanks

Excellent quality low-profile single-slot AMD GPU card requiring no extra power cable; ie plug in and go. The AMD Adrenaline and Sapphire TRIXX software are ideal for tuning the card in terms of graphics performance and quality. The correct driver can be readily downloaded and installed using the AMD web based utility. Also included is a set of useful installation instructions. Overall - highly recommended for small form factor desktop computers, representing great value for money backed by fast Amazon delivery.

First one was from Amazon Resale and had neither backplate, 2nd one came with both but cost me more. Anyway, it's relatively short but very thin (height), the card including heatsink and fan is thinner than the PCI backplate. Draws power from the motherboard PCIe slot with no extra power cables needed. Still keeps cool and I really had to push it with benchmarks to get it to turn the fan on, I think it will be silent most of the time. Was plug'n'play on Debian 13.1 using the amdgpu driver and firmware, much better than my old GT1030 with Nouveau drivers.

This card is not going to give you a good experience with new flashy games, but if you set your expectations accordingly it can do an awful lot in a tiny package. Works great in a repurposed small form factor Optiplex!
