Well I had a previous thread ( http://www.tomshardware.com/forum/362925-33-upgrading-i... ) about how I have a dell inspiron 560 with a Intel G45/G43 Express Chipset. I decided that I was going to get a Radeon 7770 ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) and a new PSU. I was going to get a 400W PSU, but I have a friend that says I should get a 550W PSU. Is this ok? As in will a PSU like that work on my pc? Thanks

With regards to the 7770, a 400w PSU should be plenty, as long as it is from a respected brand (like Corsair). The 7770 only uses 82 watts at load according to this:

That is really low power consumption for the performance you get.

But if I were you, for only 20 bucks more you can get a 6850 (which is a little more powerful).
Or for 5 bucks more than the 7770 you showed, you can get an MSI 7770 Factory overclocked (which has two fans and is a little more trusted of a brand).

So the 400W is alright? I still wanted the 550W though. Are there any downfalls to me getting the 550W? And idk about the 6850, kind of on a tight budget, but I might consider it. And the MSI 7770? What is the difference between that and the Radeon 7770 here http://www.newegg.com/Product/Product.aspx?Item=N82E168... ? Sorry, I am not a techy kind of person.

One difference between the MSI and HIS 7770's is that the MSI is already slightly overclocked (which isn't too big of a deal, you can do that yourself but that voids your warranty). But the main difference is the cooler design. The HIS one is very similar to the reference 7770, with only one fan, while the MSI has 2 fans (which should make it quieter and cooler under load due to each fan not needing to spin as fast). Also the MSI one comes with a Dirt Showdown game coupon if that matters to you (while the HIS does not).

So if I was to choose out of those two, I would get the MSI. (You might want to check any similar priced 7770's as well to make sure you get the best deal).

Also make sure you get a quality power supply. You do not want a cheap no name one to mess up your build by shorting one of your components.

I personally may add a Sapphire 6850 ($150) to my Corsair cx430 ($40). Although some people may not be thrilled with the cx line of power supplies, Corsair is a very trusted brand, and the cx430 got some good reviews. So if you want a cheap 430 watt power supply, you may want that:

I personally haven't had any problems with it (though it's only been 3 weeks).

So there would be no use of getting a 550W? My uncle said he will buy it for me free of charge so I might as well go for that. And what do you mean overclocked? And I think I might go for the MIS

If the 550W is a trusted brand (look here for a good indicator of the PSU brand quality) then 550W for free is awesome. And overclocking is basically making the card run faster: "Overclocking is the process of running a computer component at a higher clock rate (more clock cycles per second) than it was designed"-Wikipedia
(Sorry if that doesn't help too much, I'm new at all this too, I just do a lot of research, lol).

Ok. Thanks for the info. Also, how do I 'overclock" it?

Using overclocking software. MSI Afterburner is pretty well known, and comes with the MSI 7770. No matter what card you get though, you can find overclocking software free online. The software allows you to increase the clock speed and memory speed of your card, thus making it "faster." But I myself do not know much about overclocking, and there are lots of resources for overclocking here on Tom's and around the web. If you want to know more, you'll be able to find the info with a quick search, even for your specific card. Believe me, those threads will cover everything you need to know.
