PowerColer offers a Radeon HD 7750 Low Profile format aimed to HTPC. As it’s names shows, it works without additional power connector.

The PowerColor HD 7750 LP is a single slot solution in Low profile format. It features a 28 nm Cape Verde 800 MHz GPU supported by 1GB of GDDR5 at 1,125 MHz operated by a 128-bit memory bus. Under the hood we find 32 CoreNext TMUs and 16 ROPs.
The manufacturer has opted for an active cooling with the presence of a small fan of 40 nm. Hopefully it will stay quiet because otherwise the card may lose interest for HTPC use. The video connection consists of a dual-link DVI, HDMI 1.4a and a VGA port.
