Le bo\u00eetier contient un connecteur PCI-Express 16x (compatible PCI-Express 2.0) et peut recevoir des cartes double \u00e9paisseur. Il dispose d&#8217;une alimentation de 80 W, suffisante pour une carte contr\u00f4leur classique ou une carte graphique d&#8217;entr\u00e9e de gamme.<\/p>\n<\/p>\n<p>Le bo\u00eetier se relie de deux fa\u00e7ons diff\u00e9rentes \u00e0 un PC : soit en ExpressCard soit en PCI-Express. Dans le premier cas, une carte ExpressCard \/34 est utilis\u00e9e pour relier le bo\u00eetier \u00e0 un PC portable et la bande passante r\u00e9elle est faible : seulement 250 Mo\/s (PCI-Express 1x), ce qui peut poser des probl\u00e8mes pour un \u00e9cran en 1 920 x 1 080, par exemple (un flux vid\u00e9o en 1080p cod\u00e9 en 32 bits et \u00e0 30 images\/s demande plus). Reste que pour piloter des \u00e9crans pour de la bureautique, la solution est efficace.<\/p>\n<\/p>\n<p>De plus, le bo\u00eetier peut \u00eatre utilis\u00e9 sur une machine de bureau, avec une liaison \u00e0 travers une carte PCI-Express 4x adapt\u00e9e. Dans ce cas, et pour peu que la machine soit PCI-Express 2.0, la bande passante reste correcte : 2 Go\/s.<\/p>\n<\/p>\n<p>Reste le prix, un peu \u00e9lev\u00e9 : 400 $.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Voici un bo\u00eetier int\u00e9ressant qui permet de placer des cartes PCI-Express (et donc des cartes graphiques) dans un bo\u00eetier externe
