Can the XFX 6670 1GB DDR5 run on a 350w power supply?

So right now I have a stock dell 350w PSU and I THINK it has 18v rails (if that's how it's worded). I'm wondering if I can run this video card:

on it without having to buy a new PSU.

The specs of my computer are:
Dell studio 540
Intel Core 2 Quad Q8200 2.33ghz
500GB western digital hard drive
CD/DVD Drive
Stock dell 350w powersupply

Here is a picture a took of my power supply if it helps.

recommended for this card is 400W+ i would replace the psu in your pc also.

The manufacturers will always list the system requirements for thier product and with all the many different psu's out there it's hard to say which ones will work and which ones will struggle. That's why the manufacturers will up the spec's a little to cover the weaker psu's. It is going to depend on whether the Dell psu is a strong make or average ot even weak. You may end up giving Dells tech support a call just to see what they say. Give this wattage calculartor a try and see what it says you need.

400W for a 6670 is rediculous. Its only a 66W card. You could also get a 7750 which is a 55W card. If its ACTUALLY a 350W PSU you should be fine

For a system using a single Radeon HD 6670 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 20 Amps or greater.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

The Dell 350W OEM PSU, with its combined +12 Volt continuous current rating of 25 Amps and with one 6-pin PCI Express supplementary power connector, is sufficient to power your system configuration with a single Radeon HD 6670.

go for ATI RADEON 7750....if you want a better performance card upgrade your psu....otherwise go for ati 7750

A 6670 only needs about 60 watts.

Your Dell PSU is more than adequate to run your present system with a 6670.

Thanks for the good reply but I don't think the power supply you're talking about is mine. My power supply does NOT have a 6-pin PCI Express power connector. May you please take a look at this picture i took of my power supply to confirm that is does indeed have a combined +12 Volt continuous current rating of 25 Amps?

According to that photo your psu is a Liteon and it has two rails , one +12v at 12a and the other +12v at 18a for a combined 30a. So you probably have enough to run the card your asking about.

Thanks again for the reply.

On that PSU label it states:

THE MAXIMUM CONTINUOUS COMBINED OUTPUT POWER(12VA & 12VB) IS 300W.

Using Ohm's Law this works out to a combined maximum of 25 Amps.

Since you didn't provide the make and model number of the PSU I was just guessing that it may have a PCIe connector because some of the Dell 350W PSUs do come with one.

The lack of a 6-pin PCIe connector on that PSU is irrelevant for the Radeon HD 6670.

So I checked again and it does indeed have a 6-pin PCI Express connector. It was hiding behind something. So since I have a combined maximum of 25 Amps, it's presumably safe for me to install the Radeon 6670 without buying another PSU? What are the risks that it frys my whole computer?

Thanks again for the reply.

The Radeon HD 6670 is not a high power consumption card.

Your total system power consumption, including a Radeon HD 6670, should be well within that power supply's capability to power it.
