I just bought an AMD 9850 Black Edition CPU and a new motherboard a
Gigabyte GA-MA790FX-DS5 I put it in today and now it won't boot. I have a Rosewill green series PSU total power 530W, 4 12v rails at 20amps each the model number is RG530-2. Now my question is, is my PSU too weak to handle the new Phenom 9850? Or maybe the motherboard was DOA? I just want some input before I go through the RMA process. Does anyone know if 530W is enough to power the 9850 + a GTX 260 and 3 hard drives + a DVD burner? What do you think is the problem the PSU or Motherboard?

That power supply should be plenty for the system.

Not necessarily, its not watts we are talking here, its amps. The it has 4 12v rails that means it may put out 500 watts, but the amperage is no where near as much with a 500 watt PSU with just 1 12v rail.

That is the superclocked edition, but not sure is that has much more draw than any other version.

I don't know a whole lot about PSUs but the Mobo is on 1 rail, the GPU should be on another. I would assume that 20 amps is enough for the CPU and the mobo, but the GPU seems to be what needs more amps here. That is my guess anyway.

What was your setup before you added the new stuff? Let me get this straight, you started with:

System A
X mobo
X Cpu
3 hds
260 GTX

You upgraded to:

System B
AMD 9850 Black Edition
Gibabyte GA-MA
3 hds
260 GTX

If that is the case I dunno because my theory is the GPU isn't being power fully by the PSU but if you had it running before than I am wrong (no really?).

Or in that case your PSU was just barely enough to run your old Mobo and this new one requires more power. Was the last system OC'd? Is this new one OC'd?

Explain exactly what was in your last system and exactly what is in your new system.

Try running the PSU with your old stuff and see what is going on, then rebuild your old system for trouble shooting purposes.

It could be anything at this point, unless I'm not as smart as I think I am lol.

That power supply is rated at 492Amps on the +12v rails. That is plenty for his system. That doesn't mean it couldn't be a problem with the power supply, but if it is running as it should then it is not because of a lack of power.

I can't seem to load your link. I don't see how its possible for the +12v rails to be rated at 492A.

The Newegg page says:

It says 20A on each rail just like the OP said.

Yeah srry about that. I did have an e2140 @ 1.6ghz not overclocked an MSI 945pl neo 5 motherboard. Which has a very low power consumption. Compared to the AMD 9850. Maybe it is the PSU.

Thank you all for your input! I greatly appreciate it. I encourage more. The more input the better.

sLowEnd

It's 492W (41Amps total) lol
I think pip just made a typo

Anyway, the rosewill should be plenty, assuming it's not defective.

Did you install the motherboard in the case properly? (With standoffs and all)

12V Combined Output 492W (41A)

I think you meant 492W not 492Amp. I don't think there is a PSU in the world with 492Amps. Thank you for you help.
