Question about OCZ ModXStream (OCZ780MXS) 780-Watt Power Supply

1 Answer

-5v is sitting at -8.48

Unfortunately I don't know to much about power supplies, at least specifics.

Ijust installed a new PSU and according to speed fan my -5v line issitting at -8.48v. I'm relatively certain this isn't normal. My -12vline is sitting at -0.43v and my +12v is at 12.54.

It could just be something wrong with speedfan, but i can't say for sure.

It could also be something wrong with my motherboard.
I'm not sure about my old powersupply, unfortunately that could be a royal pain in the neck to test.
I'm pretty sure there is something wrong with some of my ram Slots, but i'm pretty sure that has nothing to do with it.

If anyone can shed some light on the situation that'd be great.

If you were measuring the voltage right then it seems like a power supply problem. Make sure you are measuring voltage potential with respect to common ground. Meaning the black wires on your meter probe is on the metal body of the PSU.

Is there a protection mode for this lcd visio tv that can be removed for this tv to come on ?


Hello Donald the first thing I would like to Know what the model number of your TV is. But that's ok if you have a external power supply you could try this .Make Shure your TV is not pug In to the Ac outlet. We are going to see if you have a short or a load on your 12v line. Ok you wont to unplug the 12v source from the power supply board. Fine out what pin is the 12v's. Connect your external power source to that pin, apply the 12v and see if it is drawing to much current. If so check the boards for any very hot items. If you have a problem on the 12v line. This will find the part that is loading it down. This is the old way of finding a load on a power source. I hope this will help some. P.S make Shure there is no AC connect to the TV as you do this test and you have the plug off of the power supply board before using the external power source.

Board will not start


Just after that there was NO correct answer to fix this problem causes the problem not solved even if it is marked as solved. Me too I have this problem, I was fix it by setting jumpers to default 60 Hz AC power because I won`t have 50Hz AC power or some AC power converter before PSU, I mean this is voltage errors, it`s need to be set to default +5V(60Hz) PSU not +5VSB(50Hz) PSU, (Step1) like might be set to USBPW12 to pin 3 both USB to right side inserted jumper it`s in left side of, near ATX 12v advanced CPU power cable connection socket. Next (step 2) is set up front USB jumpers to +5V or system won`t start up, it`s on motherboard about between PCI1 and PCI2 on right side it must be set up to USBPW56 and don`t set it to USBPW78(5+VBS) because system won`t start up, the jumper must be set to right side I mean it`s last jumpers to right side need to be set up, because it`s +5V(60Hz) PSU supply. The USB wake-up feature requires a power supply that can provide at least 500mA on the +5VSB lead when these jumpers are set to +5VSB otherwise the system won`t power up. Next step if it still not starts up its BIOS fault, it`s easy to repair, just (Step3) turn off PC remove BIOS battery (it`s down to IDE cables), start it up wait a bit, then turn it off and turn it again on wait a bit again, turn it off place BIOS battery in to socket to be able save BIOS settings i mean battery is need to save them otherwise settings won`t be saved and Chassis will be broken. (Step 4) Turn PC on press del key after BIOS is load in open Power\Hardware monitoring\Chassis Intruder set to Disable, save settings exit. (Step5) If BIOS (PC won`t power up) it`s Chassis1 jumper fault, it`s need set to Default (Chassis signal, and GND(Ground)), it`s between SATA 2 and SATA1(Serial ATA connectors 7-pin it`s near and down to BIOS battery, the jumpers might be set to right side, after it`s completed repeat Step3 and Step4. CMOS is BIOS battery. If that all doesn't works Take BIOS clearing jumper in it`s clear state, near BIOS chip. Turn on PC with CMOS clear jumper turned on its work. Take beck jumper in its default state after that take bios chip out and CMOS battery out both them an two times restart PC after insert all beck if PC will be working all keyboard flashes once, after its in AC power.

The user manual will give you the jumper settings but I'm surprised you haven't tried the card you have as you consider it a video problem.

Is there a comptable power supply to replace FSP250-60HEN


Although ATX power supplies conform to various specification guidelines, there is not, unfortunately, a standard ATX power supply. To find a suitable replacement power supply for your machine, we would recommend that you have the following information to hand when making your purchase:

- You will require a PSU with a 24-pin ATX connector, SATA power connectors, and a 4-pin 12V motherboard connector
- Make a note of the wattage of your existing PSU
- Make a note of the external dimensions of your existing power supply
- Be aware that your PSU has a power connector for speakers. Most PSUs do not have this, so you may need to purchase a separate power supply for your speakers.

So it is a slight variation to a standard ATX power supply. If you are not using the speaker power off the power supply, then any standard ATX power supply will work for you
