Advice on a XFX HD6850 with a Corsair HX520W??

Last response: in Graphics & Displays

Hello everyone,

I thought this would be the relevant place to ask this question, so if it isn't then please forgive me.

I'm looking at this: XFX HD6850;

http://www.novatech.co.uk/products/components/atiradeon...

But I'm a little concerned about power usage on this and the amps it uses. I've used Performance Comparison Benchmarks @ Hardware Compare to see the power it uses but I was wondering if my PSU will be able to support this. I've also been looking at forums trying to find an answer.

My specs are;

i5 2550k @ 3.4GHZ
8GB G.Skill RipJaws X @ 1600MHz
Gigabyte GA-Z68AP-D3
HIS HD4850 512MB
AVerMedia AverTV H727 CaptureHD
Lite-On DVD-RW Drive
2 HDD's
1 SSD
3 120mm Fans
2 80mm Fans
Gelid Tranquillo Rev.2 CPU Cooler
Corsair HX520W PSU
Zalman Z11 Plus

So basically with all of the above can I run the XFX 6850 on my Corsair HX520W PSU? Or would I need to upgrade that too? Which I don't really want to do at the moment.

Regards,

Kieran

Your system will be drawing roughly 350-400W on very taxing loads, where every part is stressed.


Realistically, you'll only be drawing around 200W during gaming.

Thankyou both for your replies really quickly! :) 

So would I not experience any problems if I was to buy this card?? Or do I need to invest in another PSU? I think my Corsair HX520W is a good PSU.

You should be fine with a single video card like a HD 6850. If you are planning to get dual video cards or a single card like the power hungry GTX 470+, then you might want to look at a larger PS.

That's good news so I think I'm going to purchase this card, I'm only going to be running one and not going to be corssfiring so all is then good.

Thankyou very much all for the help! :)

I've been running an overclocked HD 6850 on a 450 W PSU for the last year or so, just to give some extra perspective here.


Ohh have you?? That has given me some, so I should be okay for it then yes?? :) 

Haha :p  I have been doing some more research into the power consumption of the HD4850 and infact it uses more power then a HD6850.

I have seen graphs and learnt I shouldn't really use that www.hwcompare.com site as there is no source data or test details

So overall I should be able to run this card no problems then right??

Thanks,

Kieran

Yes, if you remove the 4850 you should be able to run 2 6850's in crossfire.


I was going to replace the 4850 with the 6850 and leave it at that because I have no intentions of crossfiring just yet, but do you think my PSU would be able to handle that??
