Upgrading My Slimline PC

[SuperSoviet]

Hi, I have an Acer Aspire AX3950-UR30P and I was looking to upgrade it but I've already picked some parts.

My current setup:
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1188411&CatId=4928

PSU: The main problem is the power but I've chosen an Athena Power AP-MTFX30 300W TFX12V. http://www.newegg.com/Product/Product.aspx?Item=N82E16817338056

GPU: I currently have Intel GMA HD graphics but I was thinking of getting a Radeon HD 5450 1GB but that was before I decided to upgrade the PSU, so whatever you guys suggest would work. I'm looking to be able to play games like Left 4 Dead 2 at high grahpics, Arma 2 (mainly for DayZ) at a little more than normal graphics and some more stuff I might buy in the future like COD. My native screen resolution is 1920x1080.

Memory: I don't REALLY have to upgrade this but if I can then why not . I was thinking of getting two of these sticks to get a maximum of 8 GB http://www.newegg.com/Product/Product.aspx?Item=N82E16820148569

PCU: I'm not upgrading this but I'm thinking this might be a bottleneck, i3-540

Thanks for reading and I hoping for useful advice

Hello SuperSoviet,

PSU: Have you bought this already? If not, get this seasonic instead (measure to make sure it will fit though). Seasonic is one of the highest quality PSU makers. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151090

GPU: That 5450 is not going to be a great gaming card. How much are you willing to spend here? For gaming on a slimline, I'd suggest you a SAPPHIRE Radeon HD 6670 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready Low Profile Video Card (100326LP ) http://www.newegg.com/Product/Product.aspx?Item=N82E16814102958

Memory: I'd go with a name brand like GSKILL, Corsair, Kingston, PNY, etc. Agree that this is the lowest priority item.

CPU: Probably not worth upgrading unless you are just going to go with a whole new system.

Final thought: Have you considered getting a full size case for like $30 and just moving everything over? Full size parts are cheaper and higher performing than "slimline" parts.

Yeah I probably should just do that but I wouldn't exactly know where to put all the parts (at same time there is google). I haven't bought anything yet but school is starting soon and I'll probably delay this until next summer, but yeah thanks for the advice.

I promise its a lot more straightforward than it seems! Graphic card and power supply just plug in. Very easy. Just take a picture of where all the cables go before taking anything apart - then its easy to put back together.
