HX620 enough power?

I've built the rig in my signature when the EVGA x58 was released in February. I originally built it with a 4870. Had no problems, except I couldn't boot from a CD to do a restore with Acronis. Wasn't important at the time, since I had a clean backup and I figured I'd deal with it later. Since then I upgraded to a 4890 and added a Creative X-Fi Fatality Platimun card.

About a month ago I finally decided to figure out the problem with booting from CD. After two RMA's (1st replacement was just DOA) I'm still having an issue, which is stranger than before.

Basically, I can install a 3870 in this rig with the Creative card and boot and restore from CD. However, when I put my 4890 and Creative card in the rig the system just continually reboots and won't start Windows. If I remove the Creative, but leave the 4890, I can boot to Windows and run fine, but still can't boot from a CD with just the 4890 installed.

Is my power supply underpowered? Or do I have some other whacky conflict?

Any help would be appreciated.
 
It's definitely enough power for a 1 cpu / 1 gpu setup. Sound cards draw very little power compared to your video card/cpu.

That's what I thought, too. Did the math when I built the rig.. I'm hoping someone in the [H] community can me point in the right direction.

Thanks for quick response.

I had a very similar problem when I finished lapping my CPU/HSF a couple weeks ago. Not sure what the CD issue is but my system would refuse to load windows fully when the sound card was installed, but would work perfectly fine with it out.

After about 15 mins or so I figured out what the problem was: Some dust got into the PCI slot where the sound card was being installed. Grab some dust-off and give her a shot. If that doesn't work I'd say start windows in Safe mode or with the sound card not in, then uninstall the sound card drivers and try again with it in.
 
I had a look at both your threads on this issue. Given the things you seem to have tried I am inclined to think you may have got a bad PSU.

That 620 if working properly should have no problems properly powering your setup. But you may have gotten a bad unit, it happens.

You don't have any old PSU laying around that you could test with?

I'll give that a shot. I did dust, but I didn't blow out the slots. Worth a shot.

Only a 400 watt, althought I just put an OCZ 500 watt in my secondary machine. I could try that. Wouldn't use it for every day use, but if my problem went away I would have a good case to present to Corsair.

Do you think 500 watts is too light, even for a test? I'd be comfortable with 550 watts, and I'm thinking 500 might be okay, but I'd hate to toast something.

Thanks for your replies. Any other thoughts would be appreciated.

You'll be totally fine testing with that 500 watt power supply IMO. Your system fully loaded probably hits 350-400 watts, but keep in mind you're NOT loading it, just idle.
 
I am using the same PSU with a similar build. My is running fine. I think the HX620 is more than enough for your build.
