Found a PSU thinking of buying it..for a GTX 275 based system.

Since my CM 600W exploded i have to get a new PSU for 2-3 months so i dont really want to spend a lot.

I have found a PSU which seems to be good and well build it had the 80% rate sticker on it. The main thing i am worried about is the Amps on the +12v1 and +12v2 rails

They were rated at 28A and 20A, that is a huge different and i am afraid if the PSU would burn the GTX275??

Anyone used such a psu with a GTX260, GTX275, etc???

Also as for the name it was not very familiar maybe Hapro or hirpo...or something

Hipro....it would help to know the specific model though...

I am not sure I understand your question....since 12V1 and 12V2 are rated at different current levels, you think it will damage something?

If that is your question, then absolutely not...it doesn't matter one bit.

Thanks thats exactly what i was asking... the 8A difference between them seemed a lot...Non of my old PSU's had such a high separation of Amp. rating.

The rating just means that is how much current it can supply, it doesn't mean that is how much it will be supplying all the time. Voltage is the only thing that should remain fairly constant. The Power that your components need will depend on them, and how much work they are doing....the A(ampere, or just amps) is a function of the voltage and the power. Power(W)=Current(A)*Electrical Potential(V)

Since the voltage should stay fairly constant at ~12V, the amount of power your components need will determine the amount of current that flows through those rails. The limit on those rails just means how much current they can handle, beyond that limit, your PSU will shut down (but it should not damage components...in fact one reason it shuts down is to prevent damage). So the difference between the current rating of the two rails means absolutely nothing.
