Can my PSU cope with this GPU?

I have a 600 W PSU. I'm considering a GPU that on paper needs 680 W. But, I also have a PCI-E 1.x slot while this card is PCI-E 2.0, as most new cards are. This alone will reduce the cards capacity, and therefore power consumption, and so I'm wondering if I can still get it without my rig collapsing? My CPU will probably also hold it back a bit, I'm not sure how much though.

The reason I'm getting a card I can't fully use is that I'm going to need an upgrade on my CPU/mainboard/PSU in a while anyway and when that time comes I want my GPU to still be kinda good.
 
It will not reduce the power consumption running on a pcie 1.x slot. What psu do you have, and what gpu are you looking at. Wattage means nothing, amperage is mainly what you need to look at.
 
Thx for replying :)
My PSU is 650 W and 5 Amps, I opened up and looked at it. What do you make of that? I'm looking at a GTX 295 by the way.

Referring to the amperage on the +12v rail, what brand is the power supply? If its a good one it should handle a GTX295, if its a crap one like HP/dell/oem's include then it wont run it. Brand/model of it?

Not a very good P/S, only has a single 25 amp rail.

But like said between the PCIe 1.0/2.0 your card will probable pull the same amount of watts. PCIe 2.0 does supply more wattage through the slot, how much more depends on the manufacture, but PCIe 1.0 is 75W and 2.0 is up to 150W. But the card will get its wattage one way or the other (slot or PCIe power connector)

Most of them are made by Topower. Some are good some are not, kinda of a 50/50 thing.

that is what i mean by some :P

I know someone that bought a decent one that ran right up to what it said it was rated at and not broken a sweat, upgraded to another tagen PSU at higher wattage thinking it would be good to upgrade and it went with a couple of months :eek: sucks to be them :P
 
Yeah, Topower can make a really good power supply, then some models 12V rail will just die underload. I would not say just dont buy one, if you see a good deal on one just read some reviews about it first. I have a old ePower/Topower/Zumax (what ever they want to call them:confused:) and it has been a really good supply.

Hiper are similar, they make some awesome power supplies that can easily match the likes of corsair, but then they will go and bring out a god awful unit
 
Why a GTX 295 do you really need a card like that to me that card is over kill. More power to you if you get it though maybe I will get one if the price is ever cut in half but by that time it will be outdated.
 
Rubbish brand but probably enough amperage.

I agree with the above posts.

What resolution do you play at?
