Hi guys.

I'm new to this whole PC modding/upgrading thing, so I definitely want some advice here.

This is my current rig (if you can call it that):
Acer Aspire AM3470G-UW10P
A6-3620 2.2 GHz Quad Core
Integrated Radeon HD 6530D
4GB RAM
500 GB HDD
300w OEM PSU

Now what I'm looking at is getting a GeForce GTX 550 Ti. Of course that will entail a new PSU. I need some advice on a PSU that is capable of running the 550 as well as OCing the CPU and possibly OCing the 550 (some advice on if I should do this would also be appreciated).

Thanks in advance.

EDIT: Working budget of about $50.

Don't buy a 550Ti, don't get a 560SE either. For that price I would look at either a radeon 7770, or a gtx 460, they run much much better. As for a PSU this is what I would look at.

It's a little to much power, but I still recommend it over anything else.

You will need to overclock the A6-3620 cpu for sure because unning at 2.2 ghz is not very fast and could be a bottleneck for any card that is too high on the list. Coming from intergrated even the 550Ti is going to seem like a powerhouse and while it is an ok card it will depend on what you intend to use it for. I don't know what your budget is for the video card but the more you can put towards the purchase of it the better off you will be especially if you are using the computer for gaming.

For a system with a single GeForce GTX 550 Ti NVIDIA recommends a minimum of a 400 Watt or greater power supply with a minimum +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connector.Taking OC your CPU and OC the 550 TI and breathing room into account i recommend you save a little more money and get http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Well whatever you decide to put in your computer, there is an easy way to find out what wattage you need from a PSU. Newegg.com has a tool to give you a rough idea of how much wattage you need for your PC.

That calculator greatly overstates the required wattage...as do all the calculators I am aware of.
