PSU to run a 4870x2?

[Merlin4458]

Looking for the cheapest but not sh!t PSU to run a 4870x2. Looking about about 700+ im guessing, but needs to be reliable enough

cheers all

You don't need 700W really but it is a hungry card.

Maybe go for a corsair 650W TX, they are pretty good value, or they were before the price shot up £15...

This is the same money and modular, I've no doubt it can run that card

There's a good idea of power draw here

certainly the worst offender but not as bad as you might think.

I don't think much of the coolermasters tbh.. I reckon the enermax would do it, I'm pretty sure Blitzen is running 2x HD4870's off of his, or he was at some point.. maybe lol

I'd rather try a corsair 450VX with it tbh but if you like the coolermasters then maybe it will do it.

Oh sorry you were asking, i thought you were telling LOL

Give it a wurl you might be suprised if the HEXUS numbers are anything to go by.

ok so im a little confused. If i were to buy a psu, whats the cheapest one to get that will do. Looking around 40/50 if possible mike

I would get the 450W VX from corsair, I THINk (hope, pray) it would do the job. You can't get much else for the money.

What on earth is the X2 for though, I hope you are gaming above 1920 x 1200.

Youll need to spend slightly more, look at the corsair/BFG range of PSU for the ones thatll give you best quality for price.

running at 1680x1050 on a 22". but bought a eXtreme Power Plus 460W, and worried it will cope with it. I cant see the point buying a 425w from corsair when thats less than what ive got now....

[staffsMike]

well it's a 450W but its a superb PSU, capable of a lot more i'd imagine.

That said if the 460W is already there.. try it.

That card is WAY overkill for that resolution though. It will barely be ticking over. Just seen your other thread, I can't see why he's replacing the 4850 with this.. he won't notice the difference. If he hasn't done it yet stop him as it's pointless.

The 4870x2 seems to need 430 watts on a full system load with a quad core from this review 4870x2 review. Perhaps around 400 watts if you're on a dual core setup.

In theory a 450w corsair may run it just fine, but it'll be delivering ~90% of its max power output, and may reduce its lifespan considerably. I'd go for a 600w above PSU, perhaps the corsair TX650.

I would say that 450W is just about the limit. Mine boots at 330W (thats single card). The x2 will probably spike to 450W at boot (assume 85% efficiency would mean 390W). I'm not sure if the 12V rail on a 450W PSU is fat enough for the 4870x2 though.

Fully agree. My old 4870 ran most things fine at 1920x1200 and I like to run everything at maximum as well as being very fussy about minimum frame rates. As many if not all decent reviews on the Web have stated, the 4870x2 is only really for gaming at resolutions higher than 1920x1200 and I would certainly consider that the minimum to make it worthwhile. It took a move to a 30" monitor for me to upgrade from a 4870 to the x2. At sub 1920x1200 you'd barely need a 4870 for most games assuming the rest of your kit is up to spec.

It's your money and a good card, but I'm with Mike, I just don't think it's a performance enhancing upgrade for your PC .

I certainly am ...with no issues
I am running the 625W version.
