XFX 6800 Ultra PCI-e

XFX 6800 Ultra PCI-e - Power drain?

I've got one of these coming from another member, but have just realised my PSU may not be up to the task.

I've seen a review that mentions they can pull 110W.

Anyone got any experience of how juicy they can be??

Cheers,

M

How many amps does your PSU have? on my friends it was drawing around 24AMPS

 

[noxidjkram@hotm]

Max. Load
+5V - 30A
+12V1 - 16A
+12V2 - 18A
+3.3V - 28A
-12V - 1.0A
+5Vsb - 2.0A

Thats a cut out of the manufacturer table...

Ahhh poopy - i've had a look at another review and it seems its gonna be FAR to hungry for my PSU.

Oh well - back to the drawing board...

I once had a Leadtek 6800Ultra PCI-E running off an enermax 485w and it was fine.

You should be fine, as you have 2x 12v rails.

Its the Antec Phantom Fanless PSU though.

If i hammer it, it has no way to keep cool.

Could be an interesting experiment though...

Anyone fancy getting one of those QTEC pictures ready for me??

Cheers,

Should be fine tbh.

I was running mine off of a Jeantech 450W PSU with 17a on both 12v rails perfectly fine.

Haha - Never thought to ask you what you were running it on - cheers Owen.

Yeah should be fine no probs at all as thats a combined 34A on the 12v rails.

 

[noxidjkram@hotm]

Cool! I'll give it a blast sometime when i have a chance then.

My new PCI-e mobo has onboard GFx anyways - so at least I have a fallback position if it proves to draw too much!

Theoretical 34a most lightly

i doubt you could load both rails to anything like that.

my tagan claims 20a per rail but will only do 35a total

Psu Calculator v1.3

A very usefull page for working out exactly what watts your psu will be supplying also copes with overclocked systems


Taken from Extreme outervision

http://extreme.outervision.com/psucalculator.jsp

The total Watts is important but the Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage. Because of the increased power consumption of the new high-power video cards the recommended minimum for +12V is 26A, for SLI 35A.

 

[noxidjkram@hotm]

Hmmm.. Recommended is 351 Watts - I have a 350w PSU...

Bit of a close shave methinks - lucky its an Antec, at least they supply their rated max ok.
