VRTX 1600 watt PSU voltage

Jump to solution

This may be a silly question and maybe this isn't the best place to ask this, but I really don't feel like calling in to Dell right now. I just want to confirm if the 1600w power supplies on the Dell PE VRTX are 110/220 v switchable like the 1100w's are. That's a simple question but I can't find the answer in writing anywhere I've looked.

Thanks.

Mtn1206,

The 1600w power supply does support both 110-240, now the difference is that with the 1600w on the lower voltage will derate the power supply to 800w. As you can see in the list below.  

100–240 VAC, 50/60 Hz (1100W)
100–127 VAC, 50/60 Hz (1600W de-rated to 800 W)
200–240 VAC, 50/60 Hz (1600W)

Another key thing is the efficiency, while connected to the larger current,  the 1600W power supply is more efficient.

1100 Watt PSU Efficiency

Voltage

10% Load

20% Load

50% Load

100% Load

Power Supply efficiency at 115 VAC

87% 91% 92.5% 90%

Power Supply efficiency at 230 VAC

89% 93% 94.5% 92%

Hope this helps.

Thanks Chris! In our case we will only have 110 available so I'm definitely glad to know about the 800w derate.

Thanks a bunch.

The derate is because a normal 110 v line setup can not handle the power needed by the PS. Best get an electrician to make the present line 220-230v or run a new line from the breaker box. Doable from just about any breaker box in the U.S.A
