Hi guys,
With my budget being in the zone of this PSU, will it be strong enough for the AMD 8320 and the GTX 660?

Definitely, only if you plan to SLI in the future could it potentially become a problem.

Someone mentioned I could SLI in the future with this card. I'm not one to use multi-monitors and I don't play games like crysis, just out of curiosity (bit new) what kind of situation may I find myself using SLI, like future games using multi-thread?

With SLI, you can throw in another one of the cards that is in your computer, and boost the performance a bit. So if you go with the GTX 660, then you want to run SLI, you buy another GTX 660 (same exact model) and plug it in, and you get a performance boost. The boost isn't double the performance, but it's substantial.

Thanks for the quick reply, roughly how many watts would the PSU have to be to support SLI with the 660?

Which motherboard do you have,not all of them are sli capable.

I don't actually have one yet, I need to get one compatible with the AMD 8320 and GTX 660, I'm on a slight budget so I was looking at the gigabyte GA-970A for 100$ after tax.

For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector (two 6-pin PCI Express supplementary power connectors if you're using an MSI GeForce GTX 660 HAWK graphics card).

For a system using two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 36 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors (two 6-pin PCI Express supplementary power connectors for each graphics card if you're using two MSI GeForce GTX 660 HAWK graphics cards).

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The XFX Pro Series Core Edition 550W (P1-550S-XXB9) power supply unit, with its maximum combined +12 Volt continuous current rating of 44 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 660 (non-Ti) graphics card. It is also sufficient to power your system configuration with two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode (except for two MSI GeForce GTX 660 HAWK graphics cards because of insufficient PCI Express supplementary power connectors).

Cool thanks for the response, is it also compatible with my amd 8320 as well then? (Sorry noob questions here)

Yes.


I noticed one guy said this about the AMD 8320 + this MSI mobo:
"also make sure your power supply has 8 pin cpu connector or order 4 pin to 8 pin adapter so your not waiting around once you get board. "

Will this be an issue with the xfx 550w?

The XFX Pro Series Core Edition 550W (P1-550S-XXB9) has:
Fixed ATX12V / EPS12V : 8 & 4+4 pin

So there's one cable with an 8-pin EPS12V connector and another cable with a (4+4)-pin ATX12V/EPS12V connector.

The (4+4)-pin connector is made to split in half so that one half can be used with motherboards that only have a 4-pin ATX12V CPU power connector.

Great, thanks again!
Looks like I'll be getting the XFX 550W and the MSI mobo,

cheers
