Do r9 290x eat 473 watts on load?

Hi!

 

 

i saw this on hardware canucks review

and it says thta on load it eats 473 watts. When they say 473 watts do they mean only the gPU eats so much or the whole system with the GPU??

"Peak Watts (Total System Power Consumption)"

 

Its the entire system combined, not just the card itself.

you cant pull more then 275watts with the 8pin+pin that the 290x has(most likely wrong but those cables do have a limit).

so a 1000 or 1200 watts PSu not needed for dual e9 290es?

[SkilledRebuilds]

One reviewer using a 290x can pull more watts than another reviewer.....if the other parts are different, they most likely are of a range of parts, some would also NOT overclock their CPU for reviews, others do the MAX CPU clock possible.

 

This variation in testing makes variation in wattage consumption easily noticeable from stock CPU vs OC'd CPU's on the same GPU

Dual 290x, aim for 550-600w alone,...decent quadcore CPU's are under 77-90w stock usually, under 120-150w overclocked... plus HDD's, SSD's ODD's, fans, motherboard power requirements...

There are many factors to consider, but they all generally state TDP or power requirements in the information to give you a guide.

you'd be fine with something like an 850 watt or high quality 750 watt as each card could use ~280 watts max,though on regular load it'd be highly unlikely that both would be at peak power consumption.

 

This is assuming the rest of your system configuration isn't insane.

Okay thx. I heard that Corsair RM series is bad? why?

of course you can, but it is out of the specifications

 

The R9 290x is even 'borderline' on stock clocks with a power draw 260 Watt on the DC side (285 Watt on AC)

you can pull more but just like anything you run the risk to breaking stuff when overclocking.

As far as I've heard the RM series should be up to par with other power supplies in the same price range.

also not worth to get them??

[ViruZ_HUN]

i think i go with Corsair AX860i

The 473 Watt are for the whole system and on the AC side of things.

Considering an efficency of let's say 90% (high auality psu) this equals 425 Watt on the DC side.

So even a 450 Watt rated PSU in theory is sufficient (if it can provide enough power on the 12V rails).

 

I would suggest at least a 550 Watt rated PSU, as PSUs tend to be most efficient in load scenarios between 1/3 to 2/3 of the rated maximum power.

RM series are the great for the price, especially in sweden.

yes yes i know its a good price where we live but i heard lots of bad things about it?

like what? I have only heard good things.

wait i will search up yester days threads...
