Corsair 1000hx or 850hx

[damesJ]

Just a quick question for you guys.. I'm starting to put together a computer and wondering if a corsair 850hx will be enough.

Components to be used:

- i7 920 - overclocked
- radeon 5870 in crossfire - also overclocked
- Swiftech MCP655-B 12v DC pump for water cooling

Thanks for the help

The Corsair HX-850 is in the top 5 PSU's on the market and will handle twim 58xx cards......Others to consider:

Antec SG-850
Antec CP-850
Seasonic M12D 850W

whether it's enough for water cooling depends on what you're adding tho, unless your going over 4.4 Ghz, I don't see a need for water.

Let this "do the math" for you....don't forget to fill in fans, cooler, external USB / firewire, all cards, and other drop downs for capacitor aging ,etc

ahh thats a very helpful calculator... thank you

I'd like water cooling not only for overclocking (not gonna go insane with it) but for the noise reduction as well.

850HX will easily take the load of those cards and CPU.
Even when Overclocked.

Go for it.
