XG Duro 900 Power Supply Review (Page 1 of 5 )
Everyone who has ever had a computer out of commission due to a failed power supply understands how important it is to find a quality replacement. If you are building a system from scratch, the PSU should be carefully selected to avoid down-time due to failure. Today we will be taking a look at the new Duro 900 PSU from MGE’s XG line.

In your computer, there are many different pieces that operate in tandem in order to support your computing experience. One of the most integral pieces, is your power supply. If your optical drive stops working, you can still use your machine. But if your PSU breaks, your whole machine is down for the count. Depending on how your PSU went bad, there could be collateral damage on top of it. I’ve seen many hard drives and motherboards ruined by power surges from a failing PSU.
The Duro 900 PSU is positioned as an industrial strength power supply. It packs a whopping 900 watts of power. Can you say “Wow?!” Here is a bit of what XG has to say about it, on their website:
The Duro power supply is built to industrial standards containing four 12V power rails that deliver a direct 12V power line to each core of a dual core processor and also one to each video card when running in SLI mode. Also, the Duro includes QuickConnect molex connectors that will allow you to easily connect and disconnect power to components. With the Duro 900 equipped with the newest ATX 2.2 standards, your computer’s performance will be driven to the max.

That’s right. It has 4 separate 12V rails. The fact that it supplies each core in a dual core processor and each card in an SLI configuration with its very own 12V supply of power is extremely cool.
In any case, here are the specs from XG’s website:
Wattage: | 900W |
ATX Version: | V2.2 |
Product Material: | Steel |
Number of 12V Rails: | 4 |
PCI Express Connectors: | 2 |
SLI Ready: | Yes |
Fans: | 1 x 80mm fan |
| | |
Additional Features: | ATX 2.2 |
| | Quad 12V Power Lines |
| | Industrial Design |
| | Sleeved Cables |
| | QuickConnect Molex Connectors |
| | Active PFC |
And here’s the power specs from the side of the box:
Output Voltage | Range | Min | Nominal | Max | Units |
+5V | +/- 5% | +4.80 | +5.00 | +5.25 | Volts |
+12V1 | +/- 5% | +11.52 | +12.00 | +12.60 | Volts |
+12V2 | +/- 5% | +11.52 | +12.00 | +12.60 | Volts |
+12V3 | +/- 5% | +11.52 | +12.00 | +12.60 | Volts |
+12V4 | +/- 5% | +11.52 | +12.00 | +12.60 | Volts |
-12V | +/- 10% | -11.40 | -12.00 | -13.08 | Volts |
+3.3V | +/- 5% | +3.20 | +3.30 | +3.46 | Volts |
+5Vsb | +/- 5% | +4.85 | +5.00 | +5.25 | Volts |
And finally, here are the voltage specs from the side of the PSU itself:
DC Output | +3.3v | +5V | +12V1 | +12V2 | +12V3 | +12V4 |
25A | 30A | 16A | 16A | 16A | 16A |
I was a bit disappointed by the 12V rails, since they were only rated to 16A each. Most PSUs have a minimum of 18A on a 12V rail. To be fair, most PSUs don’t separate out 4 distinct rails like this PSU, so in most cases this should be plenty adequate.
