Help choosing a PSU

[TomHaverford]

Hey, I'm looking for a good power supply for my PC upgrade listed below:

Current build:
GPU: AMD Radeon HD7750
PSU: 500 Watts Turbolink ATX-TL500W-BK 12V
MB: M68MT-S2
CPU: AMD FX 4100 Quad-Core Processor
RAM: 8GB DDR3

Upgrade components: http://pcpartpicker.com/p/2s1U3

The problem is, the "XFX 650W 80+ Bronze Certified ATX Power Supply" on my upgrade list isn't actually $60, it's closer to $80.
Two questions:
Is that psu still worth it for $80?
And I could get the same unit, just with 750w instead for $15 more. Any point in doing that?
Thanks!

Most of the newest power supplies only need about 600W with no experimenting. The XFX Power Supplies are great, that's all I have to say (don't really know a lot about PSUs but I have a 750W XFX and I'm very satisfied with it).

Hi - a good quality 550w PSU is sufficient for that sys & OC. Most sites recommend way more watts than needed,
and all recommend same power for the 770 as the 780, but the 770 uses less. The key spec is the +12v rail amps.

Tou need at least 34 +12v amps for your system, and any PSU with 40 or more allows plenty of headroom for OC, stress, etc.No point in going 750w with 1 GPU.

I think there were a lot of weekend deals & partpicker hasn't caught up with the reg prices yet.

This XFX has 44 +12v amps & nets to $50 after mir:

Just to clarify, did you mean that the 550w psu would work for my current rig or for the one I'm upgrading to? Thanks

I think I'm going to go with this psu: http://www.amazon.com/Corsair-Builder-Series-Watt-CX600/dp/B0092ML0OC/ref=sr_1_1?ie=UTF8&qid=1388466885&sr=8-1&keywords=600w+psu

600w just to be safe, and pretty much the same price and the psu you mentioned. Thanks for your help!

OK - but you are stepping down in quality for only 2more +12v amps. The XFX is a step up from budget level,
which the CX series is.

And, Newegg has just put the hcg620 on special - $59.99 after mir
