How much power do my PC need for future upgrades?

[cLynge123]

This is how my pc looks like at the time:
MotherBoard: M5A97 LE R2.0
CPU: AMD FX 8350 4.2GHz
GPU: RADEON R9 270X
Harddrive: 128gb SSD + 1tb HDD
Ram: 16gb corsair vengeance
PSU: Corsair vs450w

This is what im planning on upgrading it to:
GPU: Add an extra "RADEON R9 270X" and make it work with CrossFire from the motherboard
Harddrive: Add another 128gb SSD drive for Games
Ram: Add another 16gb's ram

So I know I need to upgrade my PSU, will this PSU make it all work together proberly? http://www.corsair.com/en-gb/cx-series-cx750m-modular-atx-power-supply-750-watt-80-plus-bronze-certified-modular-psu

For the r9 270x, you'd need about 500w in theory. A 450w would be cutting things a little too close.

Yes, that second PSU you listed would be more than enough.

Though, I don't understand what you mean by "crossfire with the motherboard." Do you mean you'll add a second r9 270x, or you're going to try and run dual graphics with the integrated/on-board graphics? If the latter, I wouldn't believe that a higher end card like the 270x would be compatible for the dual graphics. That's usually for cards like the r7 240/250. If you meant the former, then yes, you're all set.

yes a good 750 watt psu will be enough for crossfiring the r9 270x along with other parts....

great thank you very much guys

The 750w psu should be sufficient.
Ram and ssd make little difference.

There is little value in gaming from more than 8gb of ram.
If you are using windows 7 home premium, you need another version to access >16gb.

How do you know if it is enough or not?
