The product comes with BSMI, CB, CCC, CE, cTUVus, CU, FCC, RCM, TÜV, UKCA certifications and OTP (over-temperature protection), OCP (over current protection), OPP (over-power protection), SCP (short circuit protection), OVP (over Voltage protection), UVP (Under Voltage Protection), SIP (Surge & Inrush Protection) features and includes Energy Star 8.0, ErP, WEEE, RoHS, and Triman Environmental directives.

The retail package is really big and indicates that this product is very special. All Dark Power Pro 13 series power supplies come with 10 years of warranty and the 1300-watt variant can be found at 409.90 Euro, making it one the highest priced 1300-watt PSUs at the market.

The package is really heavy and impressive to look at, while it's a fingerprint magnet in the outside area.

after removing the top cover, we can see the internal of the big box, at the left there is the power supply, while at the right the accessories box.

Opening the accessories box has multiple layers of goodies.

The PSU dimensions are (without cables) 200 x 150 x 86 (L x W x D), (mm), and its weight is 2.41 kg, making it heavier and bigger than other power supplies, however still fits at most midi/big cases.

The used fan at the Dark Power 13 series comes from be quiet! and according to the specifications is a specially silence-optimized fan with 135mm size, FDB bearing technology, and a 6-pole fan motor. Its maximum speed is 2100rpm and even at 100% load the sound pressure (noise) it produces reaches 23.2dB(A), making it almost silence

The back of the PSU includes a honeycomb design to help transfer the produced internal heat from the PSU. You will also find the power/on-off switch.

The retail package includes a separate box

that includes all the accessories: thumb screws, Screws, Cable ties, Velcro cable ties, an OCK slot bracket with switch / OCK jumper, and a printed manual in 10 languages (DE, EN, ES, FR, PL, RU, TW, CN, JP, KC)

The included power cable is at IC19 standard and uses 3x2.08mm2 internal cables, it's the most "fat" power cable ever seen at a power supply.

The main connectors of the PSU are displayed below

The PSU is designed with modular cables in mind and has two types a sleeved cable (20+4pin) and the rest are braided. The maximum cable length is 105cm (SATA+PATA cables), while the 20+4 motherboard cable is 60cm, which should be enough even for big-sized cases. Below is a chart with all included cables and their corresponding lengths.

We would like to have a slightly longer distance between SATA and PATA cables of 200mm. Included you will find 16 braided and high-quality cables

• 1x ATX-Motherboard (20+4-pin)
• 1x P4+4 (CPU)
• 1x P8 (CPU)
• 2x 600watt 12VHPWR cables
• 6x PCI-e 6+2-pin (GPU)
• 16x SATA
• 5x PATA 

There is also an add-on bracket PCI card that enables/disables "overclocking" of the power supply. The overclocking key gives you manual control switching between the default six 12V-rail modes and the alternative massive single-rail operation. This may be found handy to overclockers or power users. Note that you can enable the overclocking function permanently by setting the jumper provided directly at the power supply, or you can enable the overclocking function by pressing the switch on the slot cover as needed. All those functions should be performed when the power supply is OFF, or else you might cause failure to the power supply.

be quiet! is proud of its internal design and use only top components for its Dark Power 13 series, high-quality Japanese capacitors which are rated up to 105°C ensuring stability, reliability, and long operating life.

The Dark Power 13 series are rated 80 PLUS Titanium, meaning you should expect around 91% efficiency at full 230V redundant, and according to the be quiet! measurements, at full 100% load, efficiency reaches 92.8%, which outperforms the official 80 Plus Titanium standard.

The output total 1300W is separated into six (!) 12V rails (or a single +12V rail if you use overclocking mode), which according to to be quiet! should cover you even in high loads and scenarios, like using the latest Intel/AMD processors with the Nvidia RTX4000 series and AMD RX7000 series. The specifications indicate

• +3.3V (A) => 25Α
• +5V (A) => 25Α
• +12V1 (A) => 35Α
• +12V2 (A) => 35Α
• +12V3 (A) => 40A
• +12V4 (A) => 40A
• +12V5 (A) => 55A
• +12V6 (A) => 55A
• -12V (A) => 0.5Α
• +5Vsb (A) => 3,5Α
• Max. combined power 12V (W) 1300
• Max. combined power 12VHPWR (W) 800
• Max. combined power 3.3V + 5V (W) 150
• Hold-up time at 100% load (ms) 18
• Power good signal (ms) 100-150

be quiet! offers an online psu calculator, which can help you estimate, which power supply you want for your system. For example, building a new system high-end system

• CPU: Ryzen 9 7950X
• GPU: GeForce RTX 4090
• Drives: S-ATA 2x, P-ATA 0x
• M.2 SSD: 4x
• RAM: 4x
• Fans: 5x
• Water cooling: 1x Pump, 3x Fan
• USB 3.1 Gen. 2: Yes
• Overclocked: CPU: 25%, GPU: 25%

with somewhat advanced-power computer parts can produce up to 1139 watts (max power), so the new Dark Power Pro 13 1300 watts can take this load without any issue.
