Would an Antec Earthwatts 380D power a G620 and a GTX 480?

Could it?

Newegg product page:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371033

Rails:
+3.3V@20A, +5V@20A, +12V1@17A, +12V2@15A, -12V@0.8A, +5VSB@2.5A

GTX 480 power consumption is said to be around 25 amps or so. Could I do it?

According to those specs, not really. It would run it, but not at load.

I have used an Earthwatts 380W to run my sig rig (some things were disconnected), and it did it, but not very well.

I would imagine it would boot up, but you might experience random shutdowns/restarts when the PSU starts to fail. That's what happened to me. I only did it long enough to get some files so I could work off my laptop when my main power supply failed.

I would go with a good 500W if I were you.

Thanks for your input. I bet the jump from an i7-920 to a Pentium G620 would be a considerable chunk of power saved. That might be enough to drop the Total Power consumption to within safe spec....

Any other input would be great. smile.gif

It looks like you'll have to split the 12v rails on the card, so it has access to enough power for load.

I'm not sure if this is advisable, though?

Yeah but from what you said it uses 25 amps(I'm about to start class so i'm not going to look this up), what about the rest of your system? Also, i don't believe you just add the amps together, but I'm not sure about that. But a 380W PSU with a GTX 480 wouldn't work well together.

Total, yes, but not on one rail.

Look at higher end units; they all have like 40amp 12V rails. This one has 17.

I know that a 380D is not the best for this situation, but it's the PSU I've got and selling a used $45 dollar PSU and shipping it is going to prove financially not viable.

I wonder if you can split the rails and draw power from each one. The 8 pin into the 480's 8 pin slot and then find a Molex on rail 2 and convert that to a 6pin....

As for the rest of the system, it won't be very much at all. An SSD and a USB 3.0 card or something.

You can try using adapters and whatnot, but keep in mind that overloading a power supply can damage other components. Is it really worth it? You can spend $50 and get a power supply that will more than handle the 480.

You would need both of the 12V rails in the EarthWatts in order to power the 480, which doesn't leave anything for the CPU. If you want to try, go for it, but I don't recommend it. Even if it worked, as soon as you put load on the system (ex. started a game), your computer will probably crash.
