I am going to buy parts to make a computer and i am unsure about buying a 480w i am on a tight budget as it is. Here is a link to the psu http://www.newegg.com/Product/Product.aspx?Item=N82E168... . Ty for for helping!

Cheap power supplies like from that brand, generally cannot 'give' the wattage they say they do. In this case, the 480W power supply is very unlikely to actually GIVE 480W.

A better choice would be the CX 430W, from Corsair, for $33.99 or the Antec Earthwatts 380W for under $30.

It was $23 the other day, and will actually give at the least 430W/380W. This is easily enough for the HD 5770 and the 3 core AMD processor and your other parts.

A 'poor' brand rated 1050W PSU exploded @ 600W. A 600W corsair PSU operated at 1000W load.

The companies cannot be sued, as they can claim that their LOGISYS Computer PS480E12 480W PSU actually gave 480W.... but perhaps this only happened when the power supply was at 0 degrees celsius or w/e. But in real life conditions, these power supplies can often explode/burn out and take with it many of your PC parts.


Lastly, Instead of the HD 5770 i'd recommend the GTX 460. Double the performance for only $130 (GTX 460 w/ 768mb).
The 1GB HD 5770 is $120... the GTX 460 768mb is significantly better despite having less video ram (1024MB vs 768mb).

So DEFINITELY buy the GTX 460 768mb @ $130 after MIR, unless you got your HD 5770 for under $90, or can get it for that.. and the CX 430 is a good idea too. Only buy psus from seasonic (too expensive), corsair or antec (From antec do not buy any 'basiq' power models, the rest of antec is gREAT). For you either the CX/VX series from corsair or the Earthwatts from Antec.

I haven't ever built a computer before but i know that to do and what things i should get but i have a very small budget and im looking for some thing good and low cost so thank and i will look into it but i think i will stick with ati i dont really like nvidia from what i have heard there cards run hot and i am not going to have the best of cooling.

oh Thank you for response this helps me alot although i would like to upgrade so i will keep in mind that i have to buy a new bigger psu when ever i do but this is just for a start. And i would love to know your idea on nvidia vs ati because as i noted i would like to go with the ati.

The GTX460 has slightly better performance than the HD5770, not "twice" the performance.

i just would rather buy the one i feel better off with and from what i have heard the 5770 runs cooler and i really cant have a major heat producing componet in my build because i will not have the best cooling when ever i first build it i will be upgrading it when i get the money though. Thanks for the extra information i really made up my mind about the card though.

You didn't mention your screen resolution, but expect to be disappointed with a 5770 if you expect to be playing DX11 games at 1920 x 1080 at high settings. At lower resolutions, it will do just fine. If ya decide to change cards, this PSU calculator will tell ya what you need when using a quality PSU.

a psu calculator where have i been? i plan to play on 1080 x 720 if im correct that is what it is.
Thanks for that info though because i plan to upgrade all of the parts i get from what i get.
