What graphics card can I buy for a HP PAVILION SLIMLINE S5206UK..
According to http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01... , you have PCI express slots. Doesn't say anything about low profile, so your options might seem pretty open, but your issue is the 220w power supply. Basically if you manage to find a card that has a minimum spec of 200w or lower, it might work (might since it also depends on other components). But I highly doubt you'll find a decent card under 200w so I would upgrade the power supply first. Also depends what games your aiming to play.
