Who needs Modular anyway.....

by AverageJoe on 3/16/2009

This unit would be great with Modular connectors like my 620 PSU from corsair. But honestly, I don't think I can go back to any other power supply unit brand. They may make memory but these units work great. In the same time I went with cheaper units and have gone through 2. this one keeps on truckin. The rundown: GOOD-- works with the new Intels. always keeps voltages at good levels. They are Quiet. Have won numerous quality awards. BAD-- Not modular got cords coming out of my ##. but this can also be a pro. No switch for the fan(not that you really need one as they are quiet). Kinda pricey compared to other units. Rebates come in Debit cards.

i was getting some bad rippling with my last cheap PSU causing it to be unstable, bought this and stuck it in. it has a SOLID voltage going under full load. plus it has the best PSU award what could go wrong, by far an amazing PSU. (single rail so you dont have to worry about wire distribution)
