Looking for a quiet, 650w PSU for gaming

Can you guys give some recommendations?

Thank you.

 

Go with Corsair. They're well built, relatively quiet and come with a 5 year warranty. The semi-modular design of this one makes routing the internal cables a bit easier. It also as the 80 PLUS Bronze energy seal, meaning it should run a bit cooler and use less energy than standard PSUs.

Hope this helps.

 

I have a 630W power supply, It's nice and you can turn the LEDs on/off

It is kinda cheap, but works for my gaming computer

 

650W may come up short for hard gaming, I would go more if you can afford it.
You may run into some cash and go Xfire or SLI. On the Oscilloscope the clear winner in wave form under varying loads is:
