Spend a lot of money on an NVIDIA RTX 40 graphics card, but the old model power supply does not have a native 12VHPWR cable? Ugly and space-consuming adapter cables are also needed. The HELA 850R Platinum is originally equipped with a 450W 16-Pin 12VHPWR cable to solve the problem of power supply cables. The ATX 3.0 power supply specification proposes twice the rated power supply rate for short-term peak power consumption of graphics cards to solve the problem. Problem, no longer need to buy a kilowatt jump to reserve!

New specification for ATX 3.0 power supplies
After the previous generation of NVIDIA RTX 30 series Founders Edition graphics cards began to use the 12VHPWR power supply interface, various power supply brands have also stepped up to launch power supply products that meet the Intel ATX 3.0 specification. What exactly is ATX 3.0? 12VHPWR Can I just use the adapter?
The most important thing about ATX 3.0 is to improve the requirements for POWER EXCURSION (that is, the instantaneous peak power consumption POWER SPIKE/PEAK POWER we often talk about). The instantaneous peak power consumption has been discussed by the community for a long time, starting from the era of AMD VEGA graphics cards There have been cases, and Taiwanese players really began to pay attention to this issue, starting from the previous generation of NVIDIA RTX 30 series graphics cards (there are even related crow memes).
The PCIE CEM organization pointed out that the POWER EXCURSION (100 microseconds) of the new generation of graphics cards in the future has the opportunity to achieve 3 times the continuous (1 second) power level, but Intel finally decided to require an ATX 3.0 power supply (in models that provide 12VHPWR connectors), As long as it provides twice the overall rated power in a very short period of time (100μs), STEPHEN EASTMAN explained that the reason why it will be reduced to only twice the requirement is because after many discussions with various power supply manufacturers, it is concluded that twice is Compare cost-effective options.
∆ The instantaneous peak power consumption stipulated in the ATX 3.0 Design Guide, the power supply exceeding 450W and equipped with 12VHPWR must meet the 100μs 200% requirement.
SilverStone HELA 850R Platinum Power Supply Unboxing
Therefore, it is recommended that players directly purchase ATX 3.0-compliant power supplies when installing the system. For example, the SilverStone HELA 850R Platinum that was unpacked today complies with the new ATX 3.0 specification and can be used in a very short period of time (100μs). To cope with the peak power of 200% of the rated power consumption of the power supply itself.
∆ The front of the box advertises that it supports 12VHPWR connectors and has passed the Cybenetics Platinum Platinum certification.
∆ There are basic product specifications and product features on the back.
∆ Support Intel ATX12V 3.0 specification, equipped with FDB fan, all Japanese capacitors, and full module cable interface.
The above-mentioned ATX 3.0 actually only has the changed architecture specification, and the size of the ATX power supply itself is still the ATX (PS2) size specification of 150mm (width) x 86mm (height), the same is true for HELA 850R Platinum The length, width and height are 150 x 150 x 86 mm, and the current case is still compatible.
The certification part has changed from the common 80PLUS certification to the new CYBENETICS certification. CYBENETICS is also a certification body. Intel has previously noticed that CYBENETICS is very careful and rigorous in power supply certification, and HELA 850R Platinum is in CYBENETICS In the efficiency test certification called ETA, the Platinum Platinum certification with an overall efficiency of ≥89% & <91% has been achieved.

For users who want the desktop to operate as silently as possible, SilverStone has installed a “SEMI-FANLESS SWITCH” button next to the power button. This button is the well-known smart fan stop function, but after turning it on, the power supply will operate at a certain temperature. Before, the internal fan would not work, so it can achieve zero noise performance with a minimum of 0 dBA.

SilverStone HELA 850R Platinum power supply burn-in stress test
Now that the HELA 850R Platinum power supply with the ATX 3.0 architecture specification is used, the test platform this time must not lose. This time we use this generation of sub-flagship hardware to build the test platform. The processor uses the 13th generation Intel Core i7 -13700K, and NVIDIA RTX 4080 graphics card to match the test, the software uses OCCT AVX and AIDA64 FPU + FurMark double-baked to conduct two stress tests for reference, and HWiNFO 64 is used to view and record data, using software monitoring will have 1~3% The deviation value data is for reference only.

Simultaneously carry out a load stress test on the processor and graphics card in OCCT AVX mode. After 30 minutes of the stress test, the built-in monitoring software is used to view the data. First, +12V is maintained at 11.904 V, and then +5V is maintained at Maximum 4.980V ~ minimum 4.900V, last +3.3V maximum 3.328V ~ minimum 3.264V.
∆ OCCT AVX mode software stress test for 30 minutes.
∆ The maximum power consumption of i7-13700K is 253.19W; the maximum power consumption of RTX 4080 is 304.33W.
Next, use AIDA64 FPU + FurMark, which is often used to test the stability and temperature of processors and graphics cards, and double-bake the two software at the same time to perform high-load stress tests. Here, HWiNFO 64 is used to view motherboard information and record data.
According to the data received after 15 minutes of testing, +12V is maintained at 11.904 V, then +5V is maintained at a maximum of 4.980V ~ a minimum of 4.900V, and finally +3.3V is maintained at a maximum of 3.296V ~ a minimum of 3.264V.

Summarize
SilverStone HELA 850R Platinum debuts with a new ATX 3.0 power supply specification and 16-Pin(12+4) 12VHPWR cable. The upper limit of power supply and consumption of 850W is more suitable for use with 13700K and RTX 4080. It is better to reserve some for other Power supply for hardware equipment.
The black flat full-module cable can be more flexible and convenient to install the whole line. The original 450W 12VHPWR cable can also replace the graphics card adapter cable. It provides 2 times the overall rated power, which is 1700W, so you don’t have to worry about the peak value of the graphics card anymore! However, when installing the machine, it is still necessary to pay attention to whether the wire is completely installed, and to reserve a 3.5cm unbending space for the outlet.
HELA 850R has obtained Platinum Platinum certification in the new CYBENETICS ETA efficiency test certification (overall efficiency ≥89% & <91%). The current sales channel is priced at NT$6390, but the five-year original factory warranty is slightly shorter This is a pity.
