Which PSU should I go for?

[liamin]

Corsair 600W or the Corsair 750W?

Corsair 600W
Direct Output= +3.3V - 25 A , +5V - 25 A , +12V - 62 A , -12V - 0.8 A , +5VSB - 3 A

Corsair 750W
Direct Output= +3.3V - 25 A , +5V - 25 A , +12V - 46 A , -12V - 0.8 A , +5VSB - 3 A

The Corsair 750W states that it has 62A while the Corsair 600W has 46A.
What is the difference between them?
Thanks

What are your specs and if they are CX series your talking about they are poor.

The Corsair CX600 is based on a significantly upgraded group regulated CWT DSAII Series platform. This model is not Haswell compatible.

The Corsair CX750 is based on CWT's PUQ (B) series platform which uses modern DC-to-DC conversion to generate its +3.3V and +5V rails. This is the only CX Series model that is guaranteed Haswell compatible.

What system configuration are you attempting to power?

I have a GTX 260 but I already purchased a GTX 770 2GB DirectCU II. but it powers off when I start to play games. Im thinking that my current PSU of 24A on the +12 rail is insufficient.

So its just the GTX 770 I want to run at full speed

A GeForce GTX 770 needs 42 amps on the 12v rail.

 

[Dark Lord of Tech]

Both units posted above will run your specs with a 770.

 

[Dark Lord of Tech]

No it only needs 42 amps on the 12v rail.

Yep I know they both will run.

But I want to get the right PSU for the long term. Will my new GTX overpower on 62A on the +12 rail ?

Thanks

The system only draws the power it needs from the power supply. The power supply is not putting out a constant 600 Watts or 750 Watts. If the system only needs 400 Watts then that is all that it will draw from the power supply unit.

With the 750 Watt PSU it just means that there is less stress placed on the power supply so it should in theory have a longer life.
