Hello, I want to buy the R9 290 Tri-x OC but I'm not sure if I have the sufficient power. I would like to know if you think my current 700W PSU will be sufficient for:

i5 2500k oc 4.2 ghz
2x4gb kingston
R9 290 Tri-x OC. (Waiting to buy it)
Samsung 840 evo 250 gb .
2xHDD .
3 Fans.
Asus P8Z68-V LX .

And here my PSU: Thermaltake 700W Litepower.
That's all. Thank you!

I ran your system specs through this Thermaltake PSU calculator -http://www.thermaltake.outervision.com/ - and it came up with 596 watts (using OC CPU, 100% PSU duty, 10% capacitor aging), try it yourself and see what it comes up with...most people consider these utilities to err on the side of caution.

You should be fine, but how old is that power supply and does it have a 8 pin pcie power connection?

PSU is more than 2 years old and it doesn't have 8 pin pcie power connector, I didn't care about it and it's really important jeje. Do you know about an adaptor of 8 pin pcie power connection?. Thank you for reply.

You can do a 6pin to 8 pin adapter, but I think you are better off getting a PSU that is capable, and has the 8 pin power connections.

EDIT: Wait looking at both different models of the Litepower 700w, it has 6+2 pin PCIe connections. Like below.



Which will work fine.
