500w PSU with 6870? - Page 2

post #11 of 29
Thread Starter 
Thanks for everyone's help. I just read this review of my power supply, though, and it seems it's really garbage and only really 405w...and even then they couldn't get 400w from it frown.gif http://www.hardwaresecrets.com/article/Thermaltake-Purepower-500-W-Power-Supply-Review/990

Guess I won't be able to run any new cards...

With a good 500w you can run CF 6870s.

Seasonic M12-II 520w is a safe bet.

CF 6870s only draws 480w for the entire system in furmark which is an unrealistic load. A single 6870 draws 306w in furmark.

Thanks but I'm not planning on spending another $100 on a PSU right now.

If I take one of my hard drives off (don't really use it) and put in a 6850, it says 399w on the wattage calculator...how good are those calculators exactly?

They're horribly inaccurate. (Math fail) They always overestimate the load with GPUs.

Calculators are just a rough guide. They are nowhere near precisely what your usage will be. Hdd's don't use up all that much power by themselves, taking one off isn't going to help much.

The calculators have margins built in them in order to account for things like spin up of the drives (which uses much more power than running) and capacitor ageing. You should get away fine with 450w though. 400 should work too, but if it were me, i would say its worth the extra to go with the 450's.

200w for CPU + MB + HDDs + Fans

Just add the rated wattage of your GPUs from there. That's a reasonable estimate of how much power you need.

405?

it according to the review, it failed 310.2 on +12V and the maximum stable is 286.5w

consider replacing your power supply first before you even think of getting a graphics card


that power supply might work but you never know, it might be a time bomb that could cost you dearly

So I see that those are for "Total system power". What is their system exactly? And how does it compare to mine? You're saying that indeed their system uses LESS power than mine shows in the calculator?

Yea but they said at the beginning it's a remarked 405w PSU is what I meant.

So what PSU's would you guys recommend now, then? Are there any decent ones int he $60 range? I was looking at Corsair's "builder" series but unsure.

These maybe?

I'm hopefully looking for something that I can pick out from newegg.com or from directcanada.com (I live In Canada)

$100?

if you really want to get a graphics card


you could get a dirt cheap quality power supply that could even power a hd 6970

650

650


this power supply cost just $36 and if you do the mail in rebate. would only cost you $16.99

http://www.hardwaresecrets.com/article/Corsair-CX430-V2-Power-Supply-Review/1284/7

very good efficiency always above 80 plus and the noise and ripple are fairly good


heck it could even pull up to 500w and the good thing is that Over current protection does work!

Thanks...but if I'm going to get a PSU I mine as well get one with higher wattage spec than I already have...

Thinking about getting this one: http://www.directcanada.com/products/?sku=11180AC1730&vpn=CMPSU-600CXV2&manufacture=CORSAIR

I'm trying to keep it on the cheaper side of things but for a good PSU as well I guess...

Also, is this a reference card? http://www.directcanada.com/products/?sku=15180BD7578&vpn=HD687AZHFC&manufacture=XFX

And would it be more worth it to buy the dual fan version instead?
