Question:
I got this power consumption concern; my rig build is aiming for powerful build at lowest possible power consumption.

Its better to just buy better chip or factory oc one? (Dont tell me to do self oc yada yada. I dont have fancy time for that)

Lets say Sapphire Toxic R9-270x vw plain R9-280x

I know the performance between these two doesn't match, but which will offer better performance/watt?

uhh.. you people not answering my question.
Ok let me make it clearer.
I can have double CF R9-290 anytime if I want. In fact im using vaporx R9-290x right now. Since im the only one in the house and I pay my electricity bill myself, I know how crazy the 290x's power usage compared to 270x that i borrow from my friend.
Im using HAF X casing, I can cramp whatever I please inside (But not without the pain of dealing with dust).
so in more polite way of saying, budget doesn't really matter. I just downgrading my rig.

In several month, Ill be finishing my study and returning to my parent house and probably staying there for year or two. Right now, im paying all the power bill by myself. I don't really care how much electricity im spending on; but this is not the case on my parent home when im not the one who deal with bill.
I even migrating to Intel i7 platform instead from FX8350 (electricity sucking vampire), to seek better power efficiency as well lower TDP (Ill probably use igpu at most of time).

I dont want to completely stop gaming either or live in crappy GPU power all the time. I just want to lower the power usage, a bit; while being able to pop my GC in when I need it.
I have no interest of using Nvidia cards either. you know lah, that fanboyism thing. its hard to explain. (and everyone had their share too jangan tipu la ).

So that's it, my selection boils down to stock 280x or factory OC'ed 270x.
its strictly between power efficiency between those two. not pure performance or price.

Unseen83 I'm usng 23' monitor (1080) and 750w Xigmatek vector (80+ silver)PSU.

Ahh thanks for some info.
RM30 is a LOT ya know, considering my parents are ecogreenpowersavingsustainableearthforfuturegeneration type, they always have low monthly electricity bill; And I have to follow their suit

My parent house around 80-90 (for 5 people). But during semester end when my other sibling coming back home as well the bill can easily reach RM300, and there go the lecture about power saving, wasting energy, importance to turn off stitch etc etc from my father
Throttling sounds like a good idea if it does reduce power consumption on idle as well, instead of just limiting max speed.
Need to experiment on this first maybe. If throttling able to reduce power on idle comparable to 270x then I dont have to buy new. (now where is my energy meter lol so long didn't use that already)

Im not that rich seriously lol
but again its not about money but frankly its about being a civilized son that doesn't suck their parent money on electricity bill

HAF X not really expensive lah, considering the build quality and its crazy nice air flow quality
I think its actually very cheap for what it offer compared to other brand/model.

Haha our family consist of 11 people (football team family), we used to be so frugal when I and my siblings are all still in school back then.
Now all already in uni money is never a problem anymore but habits on power saving still there

U guys.. i dunno lah wat to say. Im just asking simple question on power consumption of both card, and u go far ahead assuming everything based on your suit. I know what im doing, and I can afford it. Ive been using ATI cards since 2006, I know every of its quirks.

Its surprising actually when I always get proper answer more easily from kopitiam section.

nvm la. I already got my hands on both card. I can measure myself now.

Thanks anyway.

*just because you have little bit more money and can afford it doesn't mean you have to stop controlling your usage or made no effort to cut your electricity usage .
