I do know that it does pay to get a reputable brand ... there's some shockers out there apparently. Low ESR means low 'equivalent series resistance' which in layman's terms is a measure of how effective the capacitor is at filtering noise. Ripple current ratings (RCR) quantify how much current the capacitor can safely pass and the lower the ESR, the higher the RCR. Noise on computer voltage supplies can corrupt data, hence the need for high quality capacitors. Removal (desoldering) and installing the new caps must be done with great care as multi-layer boards are susceptible to damage from overheating and the physical strain of withdrawing the faulty caps. It is not really a job for the soldering novice. I'd use RS Components or Farnell as a source, and read one of the 'How To' web pages dedicated to this topic. Cheers Billy 8-{)	Billy T (70)
