Seven Power Supplies (600~800W) Roundup

e've rounded up seven PSUs between 600 and 800W from BFG Tech, Enermax, ePower, Mushkin, OCZ, Thermaltake, and Zalman. We've thrown them all into the ring against not only our beastly load generator, but also our current favorite in this wattage range: PC Power & Cooling's Silencer 750W.


Our efficiency results are pretty close overall, but there are a couple of interesting trends worth pointing out. Notice how the efficiency spread is only about four percentage points with our 50 and 75% loads. That spread grows to closer to 10 points under 25 and 100% loads.
