Hi, I need a new gaming PSU and my PC requires at 650 watts, my budget is $0-150. The lower the better, but I want quality.

I was hoping you guys could help me out. The more efficient the PSU the better too. if I could get a good quality PSU for 1300 watts for cheap I'd love that, though I can't.

Thanks!

What are you powering?

For a solid 650W unit thats pretty cheap after MIR, look at the XFX units, they are seasonic built and did well at jonnyguru.

The other version has 4 PCI-E connectors but that appears to be the only difference.

Why are you looking for a 1300W PSU on the cheap? Understand that the power requirements listed on graphics cards are for the whole system, not for the card alone.

A 1300W PSU would be awesome for efficiency, though I don't necessarily need that, those aren't cheap. I'll be using an nVidia Geforce 460, 470, 480, or something along those lines, other than that I have 4 gigs of DDR3 1600 ram and an i5 760.

I also forgot to mention, it must be modular.

Er, no it wouldn't be. Most psus are most efficient at 50% of rated power. Your system will NEVER draw that much. And at idle, efficiency on a 1300W would be awful.

First of all, you probably are going to want a 460, 570, or 580, or something along those lines. Those will want a psu from 520W to 650W. If you want to prepare for 2x460, 570, 580, you will need 750W to 850W.

So right now, your requirement is for 520W to 850W. It is not possible for us to recommend one without your being more specific.

If you want to stick with your 650W "requirement", you've gotten good recommendations. If you want to use just one 460, 570, then this psu is right for you:
