Today, we have two beefy PSUs on the test bench, both of which have been deemed NVIDIA SLI Ready and ATI CrossFire Certified. The two PSUs are the 700W OCZ 700W GameXStream and the 620W Enermax Liberty. The Liberty is a modular PSU while the GameXStream has a standard output cable configuration. Rather than just simply run tests on each PSU, we installed and left each PSU in one of our test systems for around 20 days. The test system was used mostly for benchmarking and gaming. First up to the plate was the 700W GameXStream from OCZ.
