For a system using a single GeForce GTX 580 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors.

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...

The Galaxy one selling on amazon is the best one, but i wouldnt buy a GTX 580 these days. I would get an GTX 760 which wield yield same performance for the same price and it will run much cooler and use less power. With that PSU you can run many GPUs but in a very short period of time, like 10mins before it blows and burn your computer, room and house.


Never go cheap with powersupplies, thats the worst mistake you can make while building or upgrading computers. If your budget allows you get a solid 500w PSU with any kind of certification and safety standards enough to protect your invest and your own health.

I got a good one for the money and it will run most GPU out there.

And this GTX 760 that will give you an awesome performacen with little energy demands and very good temps!

First, the PSU. Not heard of this make, so would be careful. You would be better buying a decent PSU - Corsair, Antec, Seasonic - as a poor PSU can ruin your system, and your whole day. Go for a decent 550W from one of the better brands, They are more expensive, but worth it in the long run.: eg

As for the GPU, both seem very similar if you are set on the 580. Check reviews on both cards.

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 LOGISYS 550W (PS550 E12) power supply unit, with its maximum combined +12 Volt continuous current rating of 25 Amps and with no PCI Express supplementary power connectors, is grossly insufficient to power your system configuration with a single GeForce GTX 580 graphics card.

No it won't.

That PSU has a maximum combined +12 Volt current rating of 26 Amps peak and only one (6+2)-pin PCI Express supplementary power connector.

If you don't mind, could you find a power supply with those necessities on Ebay or Amazon? I'm having a bit of trouble. I would appreciate it.
