Re: 530s Slim case PSU Upgrade?
I found the best card for the money and increases the video perormance, there is no changing out the PSU. I have been running this card in my daughters computer for a week and she plays high end games like wow and sto maxed on graphics.
The current video is the onboard with a rating of 170 via G3D (intel G33/G31 Express)
The card I bought which doesn't have a fan and 1 gig of on board memory is the MSI R4550-MD1GH Radeon HD 4550 1GB 64-bit GDDR3 PCI Express 2.0 x16 HDCP which has a G3D rating of 358
The card can be found here as of this writing for $44.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16814127458
Hope this helps for everyone with a S530 and wants to ugrade their graphics.
