I have requested a trade-in for my OCZ ZX 1000W power supply from
PC Power & Cooling. I am now running just two video cards of 5 on the mining rig. My order for a used 1000W power supply (to run the 5th video card) has been delayed by the weather. I plan to get the
Turbo Master 1350W power supply. With the trade-in, it will cost $225. If I am lucky, the trade-in unit could be under warranty.
One of the beta testers, who is more knowledgeable about computers than me (has more test equipment), showed graphs of the WCG Beta work units causing voltage spikes and said the spiking loads could lead to power supply failures. I think my unit has been going bad for several weeks. When it made sizzling noises, the computer would lockup.
