PSU decision help!

[private_joker]

Hello, i am upgrading my HP p6620f and am not sure which PSU to get. this is my first time doing anything like this, so i am pretty lost lol. im on a budget of about 200$, and already decided on the GTX 560 SE graphics card. though, i am still not sure about the PSU. i have been looking at these three the most, but any suggestions around these prices is welcomed!

(i like this one, but it has a lot of responses saying it came DOA or only lasted a couple months.)

(this one has less W for the same price, but i don't see as many bad reviews.)

(cheaper than the Antec, but never heard of the brand before!)

Thanks!

Start with what you need.
In this case, you need a 450w psu with 24 a.

It is not wrong to buy more, since the psu will only draw what wattage it needs, and will run quieter if it is not pushed to the max.

Any of the units you listed would be ok.

The first rule is to buy quality.
My short list would include Seasonic, PC P&C, Corsair, Antec, and XFX.
Or, pick a tier 1 or 2 unit from this list:
