Need help buying a PSU... Tags: Power Supplies Radeon Graphics Cards ATI Components Product Last response: January 9, 2010 11:16 AM in Components Share Anonymous a b ) Power supply a b U Graphics card January 9, 2010 10:26:34 AM I'm planning on buying a new graphics card and I'm thinking of it being an XFX ATI Radeon HD4850. I hear you need a 450W PSU for that as a minimum. Could any of you recommend me a PSU costing roughly £30-40 to buy for the card? Thanks.

I don't think that the Corsair 450VX (33 amp 12 volt rail) http://www.newegg.com/Product/Product.aspx?Item=N82E168... is that much better to be worth it. And the Antec 500 watt Basiq is a surprisingly good PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Is this the same throughout all HD4850's? I mean, will they work with all HD4850S? Because I might be buying a sapphire one instead since I found it hard to find an XFX... Can't find your answer ?
