GTX 560ti on a 400W PSU?


Nov 9, 2011
Hello all,

I'm looking to upgrade from Intel integrated graphics to a gigabyte gtx 560ti super overclock. The rest of the specs are as follows:

Motherboard: MSI H61M-P23
CPU: i3-2100 3.10 GHz
Memory: Crucial 4GB DDR3 (2 x 2GB)
HD: 500 GB Western Digital 7200/16MB/SATA-3G
Windows 7 Ultimate 64 bit

However, this is the psu I'm working with right now,

Playing BF3, SC2, WoW on a 1680x1050 monitor but upgrade to 1920x1080 eventually. Not sure if the psu can handle that since going from integrated to a gtx560 is a pretty big jump. Let me know if other info is needed.

You are definitely going to want a new PSU.

The 560 Ti would need more than 400W and that off-brand PSU probably wouldn't even put out 400W. Quite frankly, it looks pretty shaky.

Do you want a PSU that will just get the job done for now, or are you looking forward? Maybe looking for a PSU that could last a few years, possibly support SLI in the future.
EVGA recommends for a GTX560Ti , 500w with 30a on the 12v rails plus two 6-pin PCI-E power leads.

Your linked psu only has 20a on the +12v rails, a strong indicator of a cheap psu.

Whatever, do not try to economize on a cheap psu.
My short list of quality brands would include seasonic, Antec, XFX, PC P&C, and Corsair.
You might try the Antec eco 520c. It delivers 40a:


If you want to objectively, accurately and scientifically determine what PSU power is required for your Vid card and PC in both watts and 12v rail amps., the forum Utility link below will show you how easy it is to calculate this information and objectively determine which PSUs are quality built, reliable PSUs that can meet your needs. Be advised that the available 12v rail amps. is just as important as the total PSU wattage. You need both to be correct.
Your agp needs power, wth. I think the the 560 uses a pcie slot.

With a normal 560 a good 500w will be enough, but the gigabyte 560 ti SOC uses quite a bit ( have em myself ) so 600W should be safer. ( my retailer reccomended 700W but a GOOD 600W will do.
