Can my PSU cope with this GPU?

Siberian · 07-01-2009, 11:02 PM

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)

Rubbish psu, cant even run a GTX275 off that imo, let alone a GTX295. Plus its a very off brand psu.

Hmm, too bad. What are some acknowledged brands then?

Tagan make some pretty good power supplies too
