I'm afraid you need a user and a service manual. These power supplies, deliver different voltages, but the also sense some or all voltages. If you leave an output without user, it could be the whole supply shuts down. Some knowledge of electronics is a must.

How can I test voltages on the Enermax Galaxy EGA1000EWL 1000-Watt Power Supply unit out of the computer.

Most motherboards will give tell you all of the voltages being provided by the power supply in the bios under hardware or health monitoring section. Otherwise you will need a multimeter to test the different voltages. You would want to set the multimeter to the 20v or similar setting. Depending on what voltage you would want to test would determine the color of wire you would check. You would connect the black/negative/ground lead of the multimeter to one of the ground wires coming from the power supply normally a black wire. The 12v is normally a yellow wire, the 5v is normally a red wire and the 3.3v is normally an orange wire. The wires may be different colors so you may want to look up the ATX pinouts to find the exact voltages you want to measure.

It is best you replace this power supply.
These power supplies have dangerous voltages inside the unit and if you do not have electronic knowledge, any mistakes you make can be fatal.

I have presently a atx 350w power supply would yours solve my supply problem

If your ATX switch mode power supply is faulty then I suggest you replace it with a new one that is 350 watt or higher wattage.
Fixing faulty ATX power supplies is not a DIY project, there are dangerous voltages in these power supplies and can cause death or serious injuries.

Power supply

Choosing a good power supply depends on a few factors; The amount of power your PC and all it's internal/external connected devices need. The way your PC-casing is built (for airflow).

First it's important to know if you have added any internal/external hardware to the pc since you bought it (hard drives, video cards, usb devices, memory etc.). If this is the case then you definitely need to upgrade, but reading the second and third factors I mention below will shed more light on that.

Second (if possible) you need to check the voltage levels on your current Power Supply via you PC's BIOS or by using a program like Speedfan. If any of the voltages show a reading below what they are supposed to deliver, it means you need a higher amperage on your next Power Supply for that particular line. There are three lines to check (12+, 3.3+ and Core voltage). Usually Power Supplies have a Table with voltages on their sides and on the package. Refer to the one of current Power Supply to see how much amperage your new Power Supply needs to have.

Third it's important your new Power Supply has the fans positioned in the right spots. If your always make sure the air is blowing out of the casing. If it has a small fan on the back, it most likely blows outwards (sucking air from inside your PC case though the Power Supply). If it has a big fan on the top side, it's most likely designed to blow out of the top of the PC case. If it has a fan on the bottom side, it's most likely designed to **** air from the inside the PC casing and blow it through the Power Supply. However it may also be designed to blow out the side of smaller PC casings, in which case the Power Supply is position in front of the motherboard.

Fourth is kind of the-rule-of-the-thumb, always (if possible) buy a brand Power Supply. Generic/Standard Power Supplies do not nearly achieve as much power/lifetime/quality as a brand Power Supply. I recommend a Cooler Master, for their silent but powerful coolers.

Fifth but definitely not a lesser one. Check what connections your PC need. Count the amount of pins connected to your motherboard (usually either 20 or 20+4 pins). Most modern Power Supplies cover most of the connection types. But you don't want to come home with a new Power Supply that isn't going to support your old IDE drives or something.

You could help us help you by providing us with a list of Hardware your computer contains. I can search your PC type and read the specifications, but they don't show what you put extra in/on your machine.

My computer won't start. Power supply (ttgi 450ss) has a blinking green light and the power supply fan starts when plugged in. Motherboard (asus m2npv-vm) has a green light illuminated between the pci...

See if you plugged in the 4 pin power connector on the motherboard besides the main power connection on the power supply (usually black colored and its a plastic 4 pin connector)

Try another power supply if all else fails. If new power supply does not work with this unit then its a motherboard which is blown and motherboard needs replacing.

Hope this helps

When the PC is turned on the light turns green for a second and then turns off. Nothing appears on tthe monitor. The monitor has an orange light steady

Since your green light comes on momentarily, you may have hope. Look in your manual or on Dell website to how to reset your BIOS chip to the default. You do this with the power off, unplugged. There is a 3 pin jumper which should now be in the normal mode. Moving the jumper to the clear mode for 30 sec. should bring the Bios to default. Should the monitor stay on, you will have to set the time and date and maybe a couple other tweeks. Good luck.

OCZ 700 watt powers up but computer will not boot into post

I know this one can be frustating. More than likely the power supply is no good. There is a fairly high surge when you first turn on a system. If the supply sags, the system may not start. I had this ussue before. When I would just barely pull the power cord out, just enough to break the circut for a split second, sometimes the unit would boot. This is because all of the capacitors at the processor supply rail are charged, therefore less of a surge.
