"Honestly, Corsair has surprised me with this unit.
After examination of its simple internal design and small heatsinks
I was not sure if unit will be able to perform well.
But TX650 has exceeded my expectations!
During my testing, the Corsair TX650 650W power supply was very stable
and did not have any failures or other performance issues.
The voltage fluctuations were minimal and the voltages stayed well
within ATX standards."
