would my corsair psu handle a 4870x2

[tom91x91]

Ive got the chance to get a 4870x2 for fairly cheap which i think would be great for my new 24inch monitor, ive got a corsair 520w psu though (im not sure if its still for sale on ocuk, but i remember them being known as very reliable/stabe), im also running an e6400 @ 3ghz too.

Thanks

Assuming you don't have anything exotic in your system drawing a lot of power then a rough power calculation is 450W so in theory you should be OK.

However, the 4870x2 requires one 6 pin and one 8 pin power connector from your PSU and it seems unlikely that your PSU will have these.

Define fairly cheap because if you have to buy a new psu then it's not worth doing given the prices of the 6850 and 6870 cards both of which will more than likely easily be accomodated by your current psu - just my opinion.

It will be tight. You would be looking at around 450W in a loaded situation which doesn't give you a lot of scope.

ATI recommend a 600W supply so potentially you are close to it but 80 watts is a lot to be short.

Palit HD4870 X2 2GB 426w
Radeon HD 4870 X2 (R700) ** 448 Watt

One site had the card consuming 263.9 Watt just by itself.

Not sure if I'd risk it.

ah ok thanks for the advice guys, maybe ill wait and get a 6 series ati card.

Iirc something in the area of 600 - 650 is advised but you might just be 'ok' in some situations since you have a Corsair psu. I'd still change it though if you are set on buying this ageing beast.
