It has been about two years since we’ve looked at a Zalman PSU and this time around they have refined the unit and granted it a 80Plus Silver rating. This means the PSU has a minimum efficiency of 85% at any point during a load or relatively idle cycle. The ZM850-HP is also cooled by a couple of heatpipes, finned heatsinks and a large, very quiet fan. This should provide you with great performance, low noise and years of service – in theory at least. Stick around as we take a look at this PSU and get up close and personal both on the outside and the inside. We’ll put it to the test with our PSU Testing Platform and see if it holds up under load.
