RX 550 AMD Graphics Card. 4GB Sapphire PULSE

Pulse 4GB
why will you rebel? #radeonrebels

A compact yet powerful GPU, the RX 550 PULSE from Sapphire features 4GB memory and holds a host of intriguing features. Enhanced fuses and Black Polymer caps all help with your cards protection, while features such as the advanced cooling and Frame Rate Target Control push your gaming experience to its peak, for longer. These are just a few of the RX 550 PULSE’s technologies.

GPU Fuse Protection

Fuse Protection
Sapphire motherboard circuit protection

In order to protect your card, the SAPPHIRE PULSE series cards have fuse protection built into the circuit of the external PCI-E power connector to keep the components safe.

Black Polymer Caps

Power Cap
Long Life Cap Technology

High quality aluminum-made long life capacitor is not only to extend the component life time, the product reliability and overclocking ability are also improved. When operational temperatures dropped by 20°C, the product life span is going to be extended up to a factor of ten. In addition, when the operational temperature increased by 20°C, the product life span only decreased by 10%.

GPU Frame Rate Target Control

Target Control
Enhancing your PC gaming power

Frame Rate Target Control (FRTC) enables users to set a target maximum frame rate when playing an application in full screen mode; the benefit being that FRTC can reduce GPU power consumption (great for games running at frame rates much higher than the display refresh rate) and therefore reduce heat generation and fan speeds/noise on the graphics card.

Frame Rate Target Control caps performance not only in 3D rendered in-game scenes, but also in splash screens, loading screens and menus, where frame rates can often run needlessly into the hundreds of FPS. Users might wish to set a very high cap just to limit wasteful FPS like that seen in menus and such, while still taking advantage of the responsiveness given by FPS well beyond 60.

4GB Sapphire Radeon RX 550 PULSE, 14nm Polaris, 512 Streams, 1206MHz GPU, 7000MHz GDDR5, DP/HDMI/DVI-D DL is rated 4.7 out of 5 by 7.
Rated 4 out of 5 by from Excellent for small / low power consumption builds I purchased this for a small case build using a sub Matx board and an i5 that I had laying around. I was trying to build a compact rig that would do for work and light gaming but with a little more tolerance for warm weather than my ROG laptop. This is not a power hungry card, its sips power from the motherboard only, no extra power connectors required. It is so physically small i was amazed, well built and not massively noisy even under sustained load. Gaming wise I have used it for around 6 hours playing Overwatch, average fps reported by AMD software of 62 FPS using the "high" preset in game. (FPS capped to display, only 60Hz monitor) Doesn't stutter and using with a basic 1080p monitor it was a perfectly enjoyable experience. Value wise, although its a "cheap" card I would only recommend where space, heat and power consumption are a concern. It has 25% the power of an RX 570, but costs 50% as much. I am happy with it as for my use case it is excellent, I now have a small rig I can leave at the family holiday home that takes up next to no space and doesn't wake everyone else up with fan noise.

Rated 5 out of 5 by from Great performer at a good price Upgraded my old graphics card which had failed to render some of my games smoothly. Not having a great deal of free cash to spend this looked like a good option and so it proved. All my games now run smooth as silk.

Rated 5 out of 5 by from Great improvement on on-board graphics Bought the RX 550 to improve video quality on the Intel HD 4600 on-board graphics. Vast improvement and the bonus is that the card has a dynamic fan that only switches on when a certain temperature is reached. Result is I still have a quiet PC when watching videos.

Rated 5 out of 5 by from Great cards for my purposes at a great price. Great cards for my purposes at a great price. I am not a gamer but I bought 2 of these cards for HTPCs and they do the job superbly.

Rated 5 out of 5 by from Excellent Card to complement my FreeSync Monitor Excellent service once again from Scan....just what I needed foe my home computer...being in my eighties and just built my new system, no problems installing and running. If you just want a simple cheap Graphic Card this is the one for you. As they say Plenty of Bang for the Buck
