PowerColor HD 5750 Go! Green

[W1zzard]

PowerColor has engineered a unique HD 5750. Their Go! Green Edition is completely fanless using a big passive heatsink, it also works without additional PCI-Express power connector, a configuration which limits the card to 75W maximum power draw. Considering that the AMD reference design requires 92W, PowerColor had quite a way to go. Did they succeed?

I guess that the GPU are hand picked and have lower stock voltage. I wonder how far would overclock voltmoded.

I am quite happy that W1z made a little calculation on how much money can be saved by buying this card instead of the stock version. Shows that this card pays itself off after some time, and if more performance is needed, then strapping a fan on and overclocking it is a relatively easy task.

They dont really handpick GPU for a fanless design, rather pretest them at a certain voltage and clockspeed. If they pass they get sold as passive-ready chips, or low power usage chips. But i dont recall these being handpicked.

If you voltmodded this I'm sure it would go over the 75W PCI-E limit and you would have to add in another power source. But solder points for the PCI-E power connector are still there! Now that you mention this, I would be so up for doing this!

 

[W1zzard]

the bus will happily give you more than 75 W, no problem. it's just not inside the spec, which most things we do to our hardware arent

 

[angelkiller]

But I don't think the mobo manufacturer designed the PCI-E bus to give more than 75W. How much more do you think it can take? (10W more, 50?)

How the hell did that card achieve 9.7 points? The price is very near the 5770, so i don't think it is that perfect. It is big and doesn't look nice

Its noiseless and efficient, for many thats just what they were looking for, if you gonna play a lot on a big screen you better add some more $$ and buy something else and it doesn't need to be pretty if you slap it on a closed case without any window, thats probably 90% of the ppl that is gonna buy this...

good question .. i'd start worrying at around 100W

It is big and doesn't look nice

girls still like it

 

[Polarman]

Could be some issues if crossfire was attempted.

DirectX 11 won't be relevant for quite a while

Why is that a negative?

 

[GSquadron]

Anyway i like it only because it has no need of connectors, so for my 350W PSU it is the best choice. Will there be a 5770 go green verion? Or maybe better?

Passive + no aux power connector = volterra software voltage control

lol.

I always wondered how much a 5750 would overclock with voltage control.

 

[Cheeseball]

The Volterra is probably what makes it pass as a passive card considering that that particular voltage controller is very efficient (which is the reason why higher end cards use it).

 

[sLowEnd]

I'm surprised they decided to use a digital PWM and a volterra chip.

That's good stuff.

 

[damric]

well darn they are sold out at the egg.

I threw one of these coolers (Accelero S1 Rev2?) on my 4850 and I'm beyond thrilled with it. With only 2 front case fans hitting it she idles at ~32 and never goes above 60. It's the exact same temps as the stock fan but doesn't sound like a hairdryer. I honestly can't wait to toss this on my future GPU and see how it does.

 

[Meaker]

Its not an S1 because they do not fit the card. Its an S1/S2 that's shifted to avoid the DVI screen.

Hi W1zzard,

i have the same card but cannot change voltages.

I would appreciate if you could check wich are the lowest working voltages for the GPU @min and max speed (stock). And how the card's consumption reacts on those changes.

[W1zzard]

lowest voltage i could set before the card crashes is around 0.775 V

0.80 V = 13.6 W
0.85 V = 14.0 W
0.90 V = 14.3 W
0.95 V = 14.7 W

 

[Audiodude]

What about the 3D mode (700mhz)?

Greetz and thanks

Edit: In the review you state 14W idle consumption... How come?

 

[newtekie1]

What is up with the heatsink? It looks like the last heatpipe is positioned too high and comes out the top of the fins, so they just messilly slapped some silver gunk on it to make it kind of blend...:shadedshu

3d power consumption is in the review

14W is ~14.7W, my review's measurement was probably below 14.5W so it's rounded

 

[Audiodude]

Is it possible to reduce the voltage in 3D mode or is it already at the limit?
