Hello,

I have been looking around reviews for the R9 290 Vapor-X and what I noticed is it overclock really well. However with its already high power consumption (380-450W) of the default 1080mhz core speed and 1400mhz memory speed how much would an increase to 1150mhz core speed and 1500mhz of memory speed would affect on power consuption?

I am planning to get this and overclock it along side with a Seasonic G-750W 80+ Gold PSU - http://www.umart.com.au/umart1/pro/Products-details.phtml?id=10&bid=9&id2=140&sid=160049

Would this be enough for an overclocked 290 Vapor-X? If not, can you recommend me another PSU not more expensive than the stated Seasonic PSU at Umart.com.au
Keep in mind I would want to overclock this thing and put it in my current build replacing my 270X

PC spec:
CPU: FX-8350
GPU: R9 270X (to be replaced with 290 Vapor-X)
MBO: Asrock 970 Extreme4
RAM: 8GB 1333hz
PSU: Thermaltake 600W (to be replaced with Seasonic G-750W)
120GB Samsung EVO SSD & two ancient 80GB hard drives (don't judge)

Thanks!

EDIT: Tweaktown did an OC to 1135mhz and 1600mhz http://www.tweaktown.com/reviews/6388/sapphire-radeon-r9-290-4gb-vapor-x-oc-overclocked-video-card-review/index15.html
Seems to affect power consumption very little, nothing drastic. It looks like overclocking should be safe, but what is your opinion?

Thanks for an answer but how is it better in what way?
Also can you tell me which one is it at Umart? Don't know which one.

EDIT: That PSU seems to be too big (180mm Length). My current PSU is 150mm Length and it can barely fit.

Ok thanks.
If anyone else have an opinion leave it down below. I will be out of town for 3-4 days so I will check them after.

A 750psu will be more then enough for that setup, even with an oc'ed cpu and gpu.

Here's what my system pulls from the wall:
350 - 400w > Unigine Valley loop, r9 290 oc @ 1080/1350
500 - 520w > Aida64 stress test cpu/fpu/cache/gpu, r9 290 oc @ 1080/1350

Here's my specs:
FX 8320 @ 4.5ghz, 1.395v
Asus Sabertooth 990fx R2
8gig 1600mhz Corsair Dominator Memory
Sapphire R9 290 reference w/Arctic Xtreme4 cooler
Corsair AX760w powersupply
2 Samsung SSDs, 1 3TB seagate HDD

Thank you.
The R9 290 Vapor-X (which is factory OC'd) is already a higher clock card than your OC'd R9 290. So I guess overclocking the already factory OC'd R9 290 would hit 550-600W.

Don't know if you read the links I posted but "The overclock also took our system power consumption even higher to a whopping 504W, while the delta T went from 49°C to 56°C and noise increased only very marginally. This is a good result, as the Asus R9 290 went up by 12°C and was more obviously louder when we overclocked it." This is from the first link.
