Alright so im building a desktop with the following components:

Im not asking for imput on the system, some of the parts werent my choice.

Now, my video card says i need at PSU that is at least 400watts, with +12V rails at 20amps, but for the life of my i cant find any PSU in the 400-500 watt range that has +12v rail at 20amps.

My question is were can i find a PSU that is 400-500watts, around 50 bucks and can power the system that im gonna put together above?

Thanks.

Try the Antec Earthwatts models, they are very good!

Let me know if you come to a conclusion

Let me know if you come to a conclusion

none of the acntec PSUs at newegg fit my criteria.

So far im looking at these models:

I'd go with the XClio 450BL.

so far thats whats winning in my book.

Of those, I'd go for the XClio. Do realize that the +12V@20A is the total +12V amperage available over all the +12V rails, not the amperage on any individual 12V rail.

So if a psu has +12v@17A, but has two +12v rails. Would the actual amperage be 34?

That changes things... im still gonna go with the XClio.

So if a psu has +12v@17A, but has two +12v rails. Would the actual amperage be 34?

No. In some cases the rails actually do sum (e.g. the Enhance 5150GH has two +12V@18A rails, which actually do sum to 36A). In most cases, the total +12V amperage is less then the sum of the rails. the Hipro TOP-500, for example with two +12V@20A rails, only provides a net +12V@29A.

In many cases the manufacturer will print the total +12V amperage (or the +12V wattage, which can be divided by 12 to find the amperage) just below the ratings for the individual +12V rails. In other cases it may be more difficult to find, and sometimes the manufacturer will not publish this information at all.
