ePower Jaguar 450 problem

Hi All,

OK, I've been out of the scene for a while as work was supplying me my computers. So I picked up some components on Black Friday and Cyber-Monday and have finally completed assembly. I can not believe my system is drawing too much power for the PSU.

I am running the Gigabyte Mercury 3D water-cooled aluminum case.
ABIT IP35-e
E6750 dual, which overclocks nicely to 3.6 at 48-50c
2GB OCZ DDR2 "Gold"
Standard SATA HD and DVD
XFX 8800 GT @670mhz

PSU is the ePower Jaguar. I ran across this review at the time I had the chance to snag it at $23:

My problem is with the 8800 I just put in it. The system will not POST with the card in it, though it is fine with an old PCI Geforce.

On the mobo, I've got the 20 pin power connector and the 4 pin ATX12v connected.

The 8800 has the 6 pin connector on the back of the card, and included a 2-in-1 "Y" connector to combine 2 standard power connectors together into 1 6 pin.
However, the instructions say to -NOT- use this. WTF?
Nonetheless, I've tried running that "Y" connector from my PSU output, and the system will power up, and then off after 4-5 seconds.
And it will just sit there and do that.

There is an ATX4P1 aux. power output from the mobo that I could try to use, however I would need to get yet another extension.

Is this PSU really that underpowered?
Is the inrush current demand at boot simply too much for the psu?
My math is the cpu is 65w, case with mobo, hdd, dvd 65w (max), 8800 110w to total somewhere around 240w.

Am I missing something, does this have to do with single/dual rails, etc?

If I need to get anther PSU, I hear the Corsair 550VX is decent, no?

Appreciate any info.
 
Welll technically, that PSU should be able to run it since the 8800GT requires at least 22A. That Jaguar has 28A according to the label. However, not all power supplies can actually provide the power stated on their label. Especially ones that you can get for $23;).

But try getting your hands on another PSU, perferably one with a native PCI-E connection and test it out on your system. If your PC boots with the other PSU, than the Jaguar is incapable of powering your system. Then return that other PSU and buy a Corsair 550VX. :)

If the system doesn't boot with the other PSU, then you have a bum video card. Then it would be time for an RMA.

Yes the Corsair 550VX is a very excellent choice.
 
Yeah, I know not to buy really cheapo stuff, but this was during the Christmas season, and my wife found it on fatwallet. My first noodling around google found it averaging for $50-60 so I though I got a great deal once I read some reviews. Should have caught that it was from 2004..... facepalm.jpg......


I just ordered the Corsair VX 550 so I think I'll be fine. Just toss this one on the extra smiladon case I got and craiglist it out.

Thanks!
