Conclusion:
"If you need a high-wattage PSU with clean, well regulated outputs without any frills then the Turbo-Cool 510 is my pick. It had the lowest AC ripple of any unit tested with excellent voltage stability. Other units in the Turbo-Cool line offer similar performance, if you don’t need a full 650 watt peak capacity. The Turbo-Cool 510 comes with active Power Factor Correction and is available in an optional deluxe version that includes sleeved wiring harnesses, a black case and voltage adjustments. And the PC Power & Cooling units are the only ones that carry a full 5 year warranty." |
