Psu for gtx570

[qw123454321]

Later,I will buy a new computer. And I have chosen a i5 2500k and a gtx570. Is a 650W PSU enough for 2500k and gtx570? And can you recommend a sultable PSU to me. Thank you very much.

Those are good choices. A 600-650 watt PSU would be plenty sufficient for your needs. I am partial to Corsair, Antec, and Seasonic, having had good experiences with all of them.

In what country are you buying this PSU? - I'll recommend some units based on availability at your location.

As Abekl said, 600-650w is good. 850w recommended if you wish to SLI.

Recommended brands include: XFX, SeaSonic, Corsair, Antec. Always look for 80PLUS ratings. Modular/Semi-Modular would be recommended but not required.

Here is a nice calculator:

But don't stare blind on the numbers, a 650watt enermax would beat a 650 watt MS-Tech three fold. The more expensive brands also have more protections. Like overheating/overvoltage/overcurrent and short circuit protections, which protect youre house from catching on fire .

For a system using a single GeForce GTX 570 graphics card NVIDIA specifies a minimum of a 550 Watt or greater power supply that has a combined +12 Volt continuous current rating of 38 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

For a system using two GeForce GTX 570 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 800 Watt or greater power supply that has a combined +12 Volt continuous current rating of 56 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT a crucial factor in power supply selection it is only used as a guideline!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

What is your budget range (please specify the currency)?

DO you want a semi-modular or modular wired power supply or is a fully wired power supply acceptable?

What power supply brands do you have available to purchase from?

Actually, I am in hongkong, and there are few PSU that are available in my region. It may be a bit hard to find a sultable PSU for me. Anyway, thank you for your help
