Problem with delta dps-700fb

Re: Problem with delta dps-700fb

I don't know, they are each on a different rail, no sense wires on the pci-e connector.

CRAZY IDEA

One of the pci-e connectors (white wires) shares the same rail as half of the 8 pin cpu connector (1/2 are brown, 1/2 are white,) The sense wire wire on the cpu connector connect to the brown wires, though they are all connected via the motherboard. I currently have the graphics card running off the green wired pci-e connector which shares it with the disk drive connectors. Should I try switching over to the white wired pci-e connector?

Re: Problem with delta dps-700fb

That's why I asked. Could it hurt? You're sitting there with it, oh PSU Guru...

ommmmm..... ommmmmmm..... ommmmmmmm.....



Was that the way it was connected in the other system?

Ohh, forgot about that, he had a gtx260 so it used both pci-e connectors.


Aww well, still can't hurt to try.

Re: Problem with delta dps-700fb

so is it the malfunctioning psu, or is it the load?
(pun intended...heh)

if it's load, try anything, but don't connect 5v to 12v and simillar.

if not then you need el.diagram(fat chance) or same unit to cross measure those things previously mentioned pg, ps-on, ps-good and whatever....
by comparing it to good system when this one refuses to start.

toasty has one, so he'll help.....hehe...(more pun! OMG!)

alternatively you could see if any of the lytics (or other components in that vicinity) has changed the value etc.
there's something that screams "it's lytic, it's lytic" if the things are gradually deteriorating, then again we still don't really know if this psu acted the same all the time it was at your friend and you, is it new psu, etc.
if answer to both questions is "yes", might as well be that it's working on a borderline condition (because of low load) and then you need to figure out how to load it more...o sell it to somebody with server....

think i covered those 2 issues that are most likely.

Kind of funny, on sunday I almost sold it to a police station because both of their dell poweredge servers quit working when a transformer exploded, then backup generator exploded, then someone rewired the entire building with phase 3 power instead of phase 1.

The psu in this dell server was a delta dps-650fb, basically same unit with a 650W label. Unfortunately, it somehow took out the mobo too, but the psu was dead.

I don't think it is a problem with loading because I have another one in my other computer. It has a supermicro X6dal-G with only one 3.2ghz xeon, 8600gt, and 2 hard drives. It runs just fine.

Re: Problem with delta dps-700fb

easy to check, just put that one to this system (with biostar mobo) and you'll know if that delta700 dislikes something about biostar...

if they act the same, it's solved, psu is ok, if not, then you can troubleshoot it by comparing voltages, if you have the affinity.

and then next time you buy non-server psu with less watts.

Re: Problem with delta dps-700fb

Could this be a bad solder joint in the PSU? One that changes with temperature?
A loose contact pin causing poor contact in the mobo connector?
Bad crimp joint on connector wire(s)?

It only takes a -blip- on PG to make it stop the CPU. Got a scope to monitor the voltage(s)? Did you try the 1k resistor from +5v to PG?
