Will this power supply do the job?

[Green AgentTurtle]

I currently have a corsair cx500
my current specs:
intel i5 2500k oc to 3.7ghz
noctua l9i cpu cooler
gigabyte z68 mobo
1 250ssd & 1 1tb hdd
xfx radeon 7770
2 200mm fan and 2 120mm fan

specs that I will have that im not sure if my psu can handle
Corsair h80i cpu cooler andhopefully oc more
another 1tb hdd
AND ANOTHER XFX RADEON 7770 (CROSSFIRE & OC MAXED)
AND DUAL MONITOR
Now that's the problem the crossfire. Now ill my 500watts work?

Yes, at least for a while. If that PSU is not the CX-500M, it was made with some inferior Samxon capacitors that do not like heat and are known for early failure. Make sure it has sufficient airflow (either gets its own air from beneath your case, or if top-mounted you have at least one intake fan in your case, not all exhausts).

what do you mean by a while and whats the difference between the regular and the "m" version?

The 7770 Doesn't consume a whole lot of W, but I wouldn't count on a Corsair CX series (not to mention a low W as well)
to do the job in such a case.

- Added another HDD
- Switching to Water cooling
- OC a CPU
- Crossfire a 7770 + Max OC

The 7770 alone is 160W without OC, so I'd say it'll be 200W easily after OC. (full power)
An i5 2500k on 3.3GHz is around 150W, so I'd say about 175W-180W after OC. (full power)
the 2 HDDs are only about 30W at max.
The water cooling consumes about 60W. (full power)

It will be somewhere between 350W-450W, depending on the use.
So it will hold, but I would switch just to be on the safe side.
Get a PSU that will serve you for the next few years.

A HD7770 only has one PCIe power connector, therefor it cannot possibly draw more than 150W running flat out; in games it will be much lower.
The "M" version has modular cables. Although both versions were made by CWT for Corsair, only the modular ones use all-Japanese capacitors.
By "for a while," I mean that if not kept cool, the inferior Samxon capacitors in the non-modular version will age prematurely, decreasing the capacity of the PSU and/or causing the noise and ripple on its outputs to increase, possibly up to the point of instability.

I recommend this PSU for the build -

XFX Pro 650w 80+ Bronze PSU - http://www.newegg.com/Product/Product.aspx?Item=N82E16817207014

XFX use Seasonic in all of their PSUs and this will handle the power no problem at all.

Yup. Wouldn't stick with the 500W as well.

Though I would go with the Corsair TX650 (77$ after rebate)
The TX is a very good series, and the specific TX650 is also made by SeaSonic!

I'd say this is the way to go. Both are great though!
