4770 suppose to have less power consumption compared to 48XX series, but here:
http://www.techpowerup.com/reviews [...] 30/26.html it shows that 4770 eats more power than 4830 even 4850 at idle, something wrong with the test?
I'd start by double checking those figures. The 4830 is not only kow, its the second lowest card there. It beats out other lower end cards that have no where near the performance such as the 9400/9500GT. They also list the GTX285 lower then the GTX260 216, and the 9800GT higher then the GTX280. I find some of the numbers more then a little suspect to say the least.

and the article dated was June 30th 09, possibly the newest test on those cards,
but still shouldnt be that different from previous benchmark on power consumption we used to see...
anyway, there is nothing unsual on the performance test.
40nm process + lower clocks + Fewer Stream Processors = less power consumption. There's no way a 4770 pulls more power than a 9800GT, or idles anywhere near a GTX295
Note that theyre testing with 3Dmark03, theres no way thats stressing the other cards (GTX295, 4890, etc) so of course power usage will be lower. Those people are idiots. nuff said. What he said about the 4730 having a gpu voltage thats seemingly too high rings true ( 1.3v is ludicrous ), but the test is still inherently flawed.

Since the test is dated 30 June /probably the newest test ever done.
Maybe..ATI decided to 'degrade' the newest chip for 47xx series, so their 4830 and 4850 wont just pilling up in the corner, bcoz everybody are buying 4770 now.
..and thats exactly what happened to the other 47xx fellow, 4730, which insanely needs power more than 4850
Remember also that the 4830 will vary slightly as it depends which core its made from 4850 or 4870
Mactronix
Maybe the 4830 used in this test somehow the one with the 'best' core.
From performance/watt and performance/$ in high res (1920*1200)
4830 is a clear winner.
I wouldnt call this BS yet. Last week I got an Asus 4770 and I cannot get it to boot on my PC. I have a 3 month old 600w OCZ power supply and the PC does not seem to have enough power to even POST. If I pull the card and put in my old 7600gt it boots just fine. The card could be bad or the power supply could be bad (doubtful). The frustrating thing is that is I researched this card and bought it for its low power consumption, heat and noise.

...better try it @ other PC, but hard to imagine that 3 months 600 Watt OCZ will be faulty
Me either. I don't have another PC for testing so I RMA'd it back to newegg.com.
There is no way that your issue is down to power, unless its a PSU issue. Another issue could well be compatability, going from a 7600GT to a 4770 could very well need a bios update.
Way ahead of you guys. Already running the most current BIOS. The motherboard is brand new ASUS P5QL PRO. I previously tried it on an ASUS P5W DH with the same result.
My friend got his Sapphire 4770 and dropped it in to his MSI 780G and it worked with no trouble at all.... I don't know what's going on but probably a bad card. His PSU mind you is a GENERIC PSU rated @ 500W max! His card prior was a 3850.

@ TheOnion,
Can you turn off the EPU 4 engine in the bios ? It may be getting over zelous with its power conserving. Most cards need more juice than normal to boot. Could be an issue with the profile its giving the card power wise.
Im running a 4770 Heavily overclocked with a core2 stock 2.4 oced to 3.0, 2 hdd drives 2 front ports(usb/memory card reader and audio headders) and two Optical drives. And thats on a 460Watt PSU.
I said it before and i repeat there is no way on this earth that the card is drawing the sort of power that review is saying.
I RMA'd it back to New Egg. When I get my new one I will try the EPU 4 engine thing. I couldn't imagine that it would draw more then a 600w powersupply could dish out so after I got a new motherboard the only logical source of the problem had to be the card. I have had bad power supplies in the past but the OCZ is pretty new, I am no where near using all the plug and I think the owners of PC Power & Cooling should be able to put out a sturdy power supply.
As for the RMA, it will be interesting what they send back. There is a good chance they will be out of the ASUS 4770. I wouldn't mind a MSI, XFX or Sapphire, but I hope its not a BIOSTAR card.
