I recently bought 4x 700W version. RUBBISH !!! One exploded after few days. Remaining 3 despite stating 700W power off randomly when loaded to just 400W . Label states 600W continuous load - NOT A HOPE ! I had to drop the power draw on it to around 350W so it actually stays up and running. Already returned 2 of them as faulty to the supplier but I have a feeling they will just replace them and I will have to send all 4 back after further testing.
