PCI UNIV to AGP 1.0 1x adapter<\/p>\n\n\n\n

-on board 5V and 3.3V power supplies, with maximum current exceeding AGP specs. 3.3V AGP VCCIO separately filtered. All power is drawn from the PCIe power connector, zero power is drawn from the PCI slot.
-high speed level shifters, the adapter can be used in any PCI slot, 3.3V or 5V IO. Works with at least 95MHz PCI clock.
-jumper for identifying as a 33MHz or 66MHz PCI capable card.
-two fan headers, accepting 3\/4 pin fans, 5V\/12V fans, with adjustable PWM<\/p>\n\n\n\n

Tested successfully with Voodoo 3 2000\/3000, various Banshee cards, Voodoo 4 4500, Vodoo 5 5500, Nvidia TNT2, Intel i740. This adapter doesn’t support AGP sideband signaling, AGP texturing etc. Not all systems\/cards will be compatible with this adapter. Also, because the adapter increases the height of the card, not all cards are mechanically compatible, for example the V3 2000 won’t be able to fit in a regular PC case due to the position of the VGA connector. <\/p>\n\n\n\n
