The similarities between the be quiet! Pure Power 13 M 1000W and the Pure Power 12 M are exceedingly clear in its physical appearance. First, we have the same all-black finish on the SECC steel enclosure. The label and stamped company logo both face upside-down in this orientation, which signals to users that they should be pointing the fan downward. For its physical size, the Pure Power 13 M 1000W is small for the wattage, using the standard ATX form factor and 16.0cm length. Again, this is the same as previous generations of the modular Pure Power models. Most modular power supplies are longer than non-modular units by a centimeter or two, as the extra length is needed to accommodate its connector board at the back. In standard ATX or eATX chassis, this length should not be much of a problem. In smaller cases that still can hold standard power supplies, a shorter length will be advantageous, especially when you consider this is fully modular.
At the top, you can see the fan has metal bars over the intake to prevent cables or fingers from entering this area while still allowing air to flow freely here. This grille can be removed with the removal of the four screws in the corner, although I am not sure why anyone would do so. The 120mm fan underneath generates airflow by drawing air from the bottom of the power supply over the internal components to keep them cool. Exhaust heat is then able to leave out the back of the power supply through the other opening on this power supply. Five screws around the power supply keep the whole unit enclosed, with one side screw having a warranty seal. This means you cannot open the be quiet! Pure Power 13 M 1000W without risking its 10-year warranty.
On the back of the power supply, there is a standard honeycomb-style grille. On one side of the unit is a horizontally aligned male C13 power input connector with an on/off switch beside it. We do not have a zero RPM fan mode switch here because it is always enabled. As such, the fan will turn off under low enough loads. Otherwise, this ventilation area is important to allow heat to flow out of the back. Most modern power supplies have an automatic full range 110V to 240V AC line voltage selection, so there is no need for a manual switch, as seen on older power supply units without active PFC.
Like many power supplies we cover here at APH Networks, the be quiet! Pure Power 13 M 1000W is a fully modular power supply. This means all cables are completely detachable from the main unit. While it is somewhat questionable with regards to why this is necessary, since cables such as the ATX 24-pin and ATX 4-pin/EPS 8-pin have a 100% chance of being connected at all times, it may prove to be beneficial to an extent when building your computer initially.
At the rear cable connection panel, everything is clearly labeled and in the correct orientation. Similar connectors are grouped together and laid out in a logical manner. From the left side, there is a motherboard 24-pin split into two plugs. Immediately to the right of that are two 10-pin connectors labeled as P8 for the ATX/EPS 4+4 pin and 8-pin outputs. Next are two 12-pin outputs for the PCI Express connections. Nearby, there are two 5-pin connectors for peripheral headers like SATA and Molex. Finally, we have a 12+4-pin 600W 12V-2x6 PCIe 5.0 plug. One thing I do like is the fact it is quite tricky to accidentally plug the wrong cable into the wrong port, as none of them share the same physical plug as each other. This is a reasonable array of outputs in correspondence to the number of connectors on each modular cable, which should be sufficient for most users.
Overall, the build quality of the be quiet! Pure Power 13 M 1000W is good. The panels fit well together with minimal gaps, while the edges are nicely finished off. Plugs fully plug in and stay in place. The black paint does not show scratches easily, which is a good thing. Overall, this power supply is built well considering the mainstream target.
The voltage specification label is located on the outer panel of the be quiet! Pure Power 13 M 1000W. There are two main virtual rails. Up to 22A can be delivered via the +3.3V rail for a total of 72.6W, while the 22A on the +5V rail brings the output to 110W in this area. The total combined output for the +3.3V and +5V rail is 120W. In other words, your power allocation combination must fall within the limits of the listed specifications. Meanwhile, a single +12V rail delivers 83.4A or 1000W. Overall, the combined power output for the whole be quiet! Pure Power 13 M 1000W is an unsurprising 1000W. It does sound a bit confusing to understand how this works at first, but this configuration allows for flexible power demands and should be sufficient to accommodate most users. The overall distribution is reasonable for a 1000W power supply.
The be quiet! Pure Power 13 M 1000W is 80 Plus Gold and Cybenetics ETA Gold certified on the box, but if you go to the Cybenetics website, they have upgraded the rating to Cybenetics ETA Platinum. The 80 Plus Gold certification means that it is at least 87%, 90%, 87% efficient at 20%, 50%, and 100% load, respectively. Cybenetics ETA Gold means at 115V input, it is certified to be between 87% and 89% overall efficiency, power factor above 0.970, greater than 75% 5VSB efficiency, and less than 0.19W vampire power. Higher certifications available for power supplies of this type include 80 Plus/Cybenetics ETA Platinum, 80 Plus/Cybenetics ETA Titanium, and Cybenetics ETA Diamond at press time.
A total of eight modular power cables is included out of the box. All modular cables, other than the ATX 20+4-pin cable and 12V-2x6, are flat and easy to bend, making them extremely easy to work with. The other two cables, on the other hand, are sleeved rather than flat. 16 AWG wires are found on the CPU and PCI Express cables. Everything else is 18 AWG, which is standard and to be expected.
The following modular cables are included out of the box:
- 1x ATX 20+4 pin, 55.0cm
- 1x ATX 4+4 pin, 65.0cm
- 1x EPS 8 pin, 65.0cm
- 1x 12V-2x6 PCIe 12+4 pin, 60.0cm
- 1x PCIe 6+2 pin, 2 connectors each, 50.0cm to first connector, 15.0cm spacing thereafter
- 2x PCIe 6+2 pin, 60.0cm
- 1x SATA/Molex, 4 connectors, 50.0cm to first connector, 15.0cm spacing thereafter
- 1x SATA, 4 connectors, 50.0cm to first connector, 15.0cm spacing thereafter
These are specified measurements from the manufacturer. Most users should have no problems with be quiet!'s Pure Power 13 M 1000W in modern cases. The minimum standard is around 50cm to the first connector, which is met or exceeded by all cables provided with this power supply.
