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

Works perfectly in sff low tdp cheap modern card to add to any old pc

This is a good option if thermal design power is a consideration and it fits in a small form factor PC. AMD Alchemy is very useful for configuring games and it’s compatible with most games. I would hesitate if you are looking for maximum performance, but for my purposes I’m very satisfied, and it was easy to install.

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.

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.

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.

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

I get great performance in my LP desktop pc and it arrived on time, I’m not sure how loud it is because my cpu fan is very loud but if I had to guess it’s not very loud

It’s a bit noisy under load but otherwise performs as expected.
