Since Computex back in June, Gigabyte has been pushing a new power delivery system across parts of its motherboard range. This involves an integrated circuit to combine power delivery MOSFETs into a small form factor with great heat dissipation, high efficiency and a smaller PCB space – the PowIRStage IC3550 they have been using is rated up to 60A of current each. This makes sense in the high end spectrum (Z77X-UP7) where power might be needed, or in low airflow situations (mITX) to ensure longevity. But is it required on a desktop Trinity board? These things are expensive, which made me wonder if it is a worthwhile investment in a desktop Trinity system. Read on for the full run-down of the F2A85X-UP4.
