Intel has introduced a new ATX12V V3.0 power supply design guide and specification. Unlike 80 Plus, ATX 3.0 doesn’t have a certification mark; instead, power supply brands add this specification to the product box themselves. So, how can you confirm if a power supply has passed the Intel ATX12V V3.0 specification?
In fact, Intel provides a free ATX 3.0 power supply validation test platform. This platform utilizes testing equipment worth approximately 6.08 million Taiwan dollars to conduct a comprehensive six-hour automated test covering more than 600 test items. Upon completion, it generates a detailed report of around 90 pages, including design improvement recommendations. If the power supply passes the test and the manufacturer opts to disclose the information, Intel will list the power supply in its online database.
GIGABYTE UD series power supplies have traditionally employed black flat modular cables. These flat cables are particularly advantageous in cases with limited space for cable management behind the motherboard. Nevertheless, the cables of the GIGABYTE UD1300GM PG5 have a certain degree of stiffness, which might require additional effort to bend and tie.
The power supply comes with a set of ATX 20/24-Pin motherboard power connectors. There are also two 8-Pin CPU connectors. High-end motherboards like the Z790 AORUS XTREME require two 8-Pin power connections, which the GIGABYTE UD1300GM PG5 can effortlessly accommodate, providing a full power supply.
The conventional PCIe 8-Pin graphics card power supply interface on the GIGABYTE UD1300GM PG5 comes with three Y-shaped breakout cables and two single-head straight-through cables. Both types of cables are designed with black flat wires for efficient cable management.
GIGABYTE has specifically updated the UD PG5 model in the Ultra Durable series to natively support 12+4 Pin 12VHPWR power supply cables, providing direct compatibility with the new generation NVIDIA RTX 30/40 series graphics cards. This eliminates the need for adapter cables. The 12VHPWR cables, with their 12+4 Pin connector effectively making it a 16-Pin connector, have specific requirements regarding wire diameter and arrangement. Hence, these cables are covered with a braided sheath for added protection and durability.
For powering additional devices, the GIGABYTE UD1300GM PG5 includes two different types of power cables. One type features four SATA connectors, each with a 180° end angle, with a total of three cables offering up to twelve SATA power connections.
The other cable type includes three large 4-Pin (Peripheral) connectors and a Floppy disk drive power connector. With two of these cables provided, you have a total of six Peripheral connectors and two Floppy connectors. However, these two power connector types are becoming less commonly used in newer-generation desktops.
GIGABYTE UD1300GM PG5 Power Test
This power supply test platform utilizes a 13th generation Intel Core i9 13900K processor, paired with the Z790 AORUS XTREME flagship motherboard, and a GeForce RTX 4090 GAMING OC 24G graphics card for testing purposes. The software used for stress testing includes OCCT AVX2 and a combination of AIDA64 FPU and FurMark, with HWiNFO 64 used to check and record the values reported by the motherboard’s environmental control chip. Please note that there can be a 1~3% deviation in software monitoring, and the data provided is for reference only.
Test Platform Specifications:
- Processor: Intel Core i9 13900K

The first step in the testing process is to use OCCT AVX2 mode to perform a load stress test on both the processor and graphics card simultaneously. After conducting a 15-minute stress test, data is analyzed through the Super I/O environmental control chip on the motherboard. Initial findings indicate that the +12V is sustained between a maximum of 12.096 V and a minimum of 12.024 V, while the +5V is maintained within a maximum of 5.040 V and a minimum of 5.010V.
Subsequently, the test employs AIDA64 FPU and FurMark. These are commonly used to assess the stability and temperature of processors and graphics cards, respectively. The two software programs are run simultaneously to execute high-load stress tests. HWiNFO 64 is employed to view motherboard information and record data.
After 20 minutes of testing, the recorded data indicates that the +12V is maintained at a maximum of 12.096 V and a minimum of 12.024 V. The +5V is held steady between a maximum of 5.040 V and a minimum of 5.010V. Lastly, the +3.3V is maintained within a range from a maximum of 3.324V to a minimum of 3.205V.
During the OCCT AVX2 testing, a FLIR ONE Pro infrared thermal imaging camera, specifically designed for mobile phones, was used to measure the temperatures of the power supply and cables. The graphics card’s 12VHPWR power supply wire was connected directly to the power supply slot of the graphics card, bypassing the use of the adapter wire that comes with the graphics card.
This time, GIGABYTE has introduced the first 1300W power supply that exceeds the kilowatt level to the Ultra Durable power supply series, known for its value. The UD1300GM PG5 stands as the first 1300W power supply model among all GIGABYTE power supply products.
Despite the increased body length from 14cm to 16cm due to higher wattage, the internal fan has also been enlarged to 14cm. The use of an HYB smart fan, combined with the built-in smart fan stop function, offers a quieter experience during standby. Internally, the main Japanese capacitors comply with the Intel ATX 3.0 specification and have passed the 80 Plus Gold efficiency test and certification. Safety features include six types of circuit protection designs, such as OVP/OPP/SCP/UVP/OCP/OTP. Other product features include a 10-year warranty and a fully modular cable design.
Given that the Ultra Durable series has always been among GIGABYTE’s most cost-effective power supplies, I predict that the price of the UD1300GM PG5, expected to be released in early June, should be fairly reasonable. The power supply demonstrated stable capability and good performance in tests, even when paired with high-end flagship hardware like the 13900K, Z790 AORUS XTREME, and GeForce RTX 4090 GAMING OC 24G. If it’s priced competitively upon release, it would definitely be a new power supply option worth considering.
