Going to be upgrading to a EVGA 560ti video card. Currently have a Corsair tx650psu. I have a feeling this won't be strong enough.

Looking at two other psus.

XFX Core Edition 750 watt, P1-750S-NLB9

Cooler Master Silent Pro Gold Series 800watt, RS800-80GAD3-US

Which would be the best pick out of the two. XFX or Cooler Master?

Or would the corsair 650 be sufficient?

My System


I would get the XFX power supply. Their made by SeaSonic for XFX and come with a 5 year warranty.

Ditto ^
The CM is not a bad PSU but the XFX is the better quality and you will want 750W minimum for the 560 ti.

Some specs. first:

Quote:
Maximum GPU Temperature (in C) 99 C
Graphics Card Power (W) 170 W
Minimum Recommended System Power (W) 500 W
- Nvidia

Quote:
Minimum of a 500W power supply.
(Minimum recommended power supply with +12 Volt current rating of 30 Amps.)
- EVGA

So while your Corsair 650W PSU is "sufficient", it's always a good idea to have some headroom to allow for loss in efficiency / capacitor aging.

In short, yeah a good 750W PSU is a better investment.

Quote:
XFX Core Edition 750 watt
Yep, this is a good PSU.

Other recommendations:

Seasonic X750 Gold
Corsair Enthusiast Series TX750 V2 (or HX750 Modular)
PC Power and Cooling Silencer Mk II 750W

We recommend 750W for a 560 ti because it is a very power hungry card. Some even recommend 850W.
The XFX & Corsair PSU's we recommend are made by SeaSonic and they are top quality.
We do not recommend the PCP&C Mk II Series (made by Sirtec).
Reading the link below would be beneficial.
