Im looking for a good PSU at a reasonable price. It has to be one of the following, since some of the best ones are either too expensive or not available at all here in Argentina. The PSUs I have in mind are: Corsair cx series, cs series, rm series, nzxt hale82, coolermaster silent pro m, coolermaster silent pro m2. My specs are: i7 3770, gtx 770. No overclocking and no SLI. I would really appreciate some advice!
