|Q1 : How to properly install a power supply onto your computer system?
A1 : Power Supply Installation InstructionFor New System
1. Consult your system or chassis manual to open your computer chassis properly.
2. Position the power supply into your computer chassis and secure with screws.
3. Connect DC output connectors to mother board and peripheral devices.
a. Attach the (20+4) pin main power connector to mother board 24 pins connector. Or use the 20 pins
main power connector to connect to mother board 20 pins connector.
b. Attach the 4 pins +12V power connector to mother 4 pins connector.
c. Attach the peripheral 4 pins connector to the peripheral devices. The Serial ATA connectors are for
your hard disk drivers with Serial ATA interface.
d. Attach 4 pins floppy disk driver power connector to the floppy driver.
e. Attach the 6 pins +12V power connecto r (s) to PCI-E graphic card (s).
4. Arrange the wires carefully to avoid any wires to block the CPU and/or system fan.
5. Follow the system or chassis manual to close your computer system chassis properly.
6. Check the power supply input voltage range switch if set on correct position (115 or 230).
7. Connect the power cord to the power supply.
8. Switch the " I / O " AC power switch to " I " status then turn on your computer.
1. Make sure the system power is turned off and power cord is disconnected.
2. Consult your system manual to open the system chassis properly.
3. Disconnect all old power supply DC output connector from mother and other peripheral devices.
4. Remove old power supply screws from the system chassis then remove old power supply from the
5. Follow above step 2 to 8 to complete the new power supply replacement and run your system with
new power supply.
1. Do not open the power supply chassis. Warranty is void if the power supply chassis cover removed.
Under no circumstances should the power supply cover be opened. There are dangerous high
voltages inside the power supply.
2. Make sure the input voltage range switch is on right position before plug the AC power cord and turn
on the power supply. Wrong input voltage switch setting will cause the system can not operation
properly or damage the power supply permanently.
3. Please keep the power supply away from humidity and do not block the exit of the air flow when
Trouble Shooting :
If the power supply fails to operation properly, please follow below step to check before return for repair.
1. Does the input voltage range switch in right position?
2. Does the AC power cord plug properly from wall outlet to AC inlet of the power supply?
3. Ensure the power supply " I / O " switch is switched to " I " status.
4. Check all DC output connectors are properly connected to all location and devices.
5. Recycle turn-off and turn-on the power supply through the " I / O " switch with intervals at least 20
Q2 : How intelligent and quiet is the fan control system in Glacialpower power supplies?
A2 : Acoustics Noise : 0 ~ 25dB
Q3 : How does Glacialpower grade power supplies?
||AC Input Range (Vrms)
||Output Power Rating
||90 ~ 132, 180 ~ 264
||0 C ~ 50 C
||115 & 230 (+/-10%)
||0 C ~ 50 C
||115 & 230 (+/-10%)
||Full Load at 25 C
||0C~50C. Above 25C the Max Output Power De-rated 2W/C.
||230 Only (+/-10%)
||Full Load at 25 C
||0C~50C. Above 25C the Max Output Power De-rated 3W/C.
Q4 : What does Glacialpower mean by real power?
A4 : The power supplies made by Glacialpower can provide continuous rated output power without any de-rating at an ambient temperature up to 50°C. Some manufacturers exaggerate their wattage claims by assuming an unrealistic ambient temperature of only 25°C. When the ambient temperature goes above 25°C, the maximum allowable output power of those power supplies must be de-rated below their rated output powers.
Q5: What is the model name assignment rule for Glacialpower power supplies?
GP : Glacialpower Identification Code
1 ~ 2 : Series Code (such as PS, LS, AS.etc)
3 ~ 5 : Output Power Rating (such as 300 = 300W)
6 : Product Grade Code (such as A, B, C, D..etc)
7 : Optional Function Identification Code(such as P=Passive PFC, N=Non-PFC.etc)
A = Active PFC with Universal Input Range.
B = Active PFC with 230Vac Input Range Only.
C = Active PFC with 110Vac Input Range Only.
P = 110Vac & 230Vac Manual Selection Input Range. Passive PFC for 230Vac input range only.
N = 110Vac & 230Vac Manual Selection Input Range. Without PFC for both input voltage range.
8 ~ 9 : Optional for business purpose (Blank, 0~9 or A~Z)
Q6 : My computer will turn on, but will not boot. Could it be my power supply?
A6 : Check the output voltages with a voltmeter. If they're all within 5% of nominal (5.0V, 12.0V, etc), the problem is probably motherboard or software related. To confirm, swap-in a spare power supply (known to be good).
Q7 : My computer locks up. Could it be my power supply?
A7 : This is most likely a motherboard, video, or software problem. After ruling out these causes, try a higher-wattage power supply (known to be good).
Q8 : My computer intermittently shuts off. Could it be my power supply?
A8 : Power supplies have a circuit called Overcurrent Protection (OCP). If a component in the computer malfunctions intermittently(make sure cards are seated properly), it will draw excessive current, trip the OCP circuit, and shut off the computer.
Q9 : My computer is noisy. Is my power supply bad?
A9 : First, determine the primary source of the noise. The CPU fan, video fan, case fans, and hard drives may be producing far more noise than the power supply itself. Next, isolate the noise from the power supply from the other sources. If the noise is the sound of rushing air, it's normal. And, in a heavily loaded system, the noise can be quite noticeable. If the noise is a grinding mechanical noise or a high pitch electrical whine, call for further assistance.
Q10 : Are the voltages indicated by my motherboard monitoring software accurate?
A10 : Usually not. To check the accuracy, use a high-quality voltmeter to measure the +5V (red) and +12V (yellow) on an unused drive connector while the computer is running. Note: the GND lead from the voltmeter goes to a black lead on the drive connector.
