Box & Bundle
Strangely enough, the box doesn’t have a photo of the PSU on its front side. Only the model description and a mention of the ten-year warranty.
Product Photos
The PSU’s small dimensions and the unique design of the fan grille make an appealing combination. On the PSU’s front side, you will find the AC receptacle, the power switch, and another switch to toggle on/off the fan’s semi-passive operation. Around the back, the modular panel has eleven sockets, including a native 12V-2×6 one.
Cables
Modular Cables | ||||
Description | Cable Count | Connector Count (Total) | Gauge | In Cable Capacitors |
---|---|---|---|---|
ATX connector 20+4 pin (610mm) | 1 | 1 | 16-18AWG | No |
4+4 pin EPS12V (750mm) | 2 | 2 | 16AWG | No |
6+2 pin PCIe (750mm) | 3 | 3 | 16-18AWG | No |
12+4 pin PCIe (700mm) (600W) | 1 | 1 | 16-24AWG | No |
SATA (500mm+150mm+150mm+150mm) | 2 | 8 | 18AWG | No |
4-pin Molex (450mm+120mm+120mm) | 1 | 3 | 18AWG | No |
The amount of cables is sufficient, and the same goes for their length. The available connectors include two EPS, three PCIe 6+2 pins on dedicated cables, and a single 12V-2×6 cable with the PSU’s setting for 600W. According to Intel’s test plan, it should be at 300W, but most manufacturers go for full power on this cable. The EPS and PCIe connectors mostly use 16AWG gauges for lower voltage drops.
The number of peripheral connectors is sufficient, and the distance between the SATA connectors is adequate. On the contrary, the 4-pin Molex connectors are relatively close to each other.
Bad fan profile settings. Initial fan speed is too high, 940 rpm is loud. It was better before.
I can confirm the fan in GX-850 V4 is way too loud (I have the PSU here). Indeed it starts spinning at too high RPM. The fan curve is absolutely terrible. Even at 360 Watts load during gaming the PSU fan in the GX-850 V4 is by far the loudest component in my PC. I compared the GX-850 V4 ATX PSU against my Seasonic Focus SPX 2021 SPX-750 750W SFX PSU with a 92 mm fan (vs 135 mm fan inside the GX-850 V4) and the small SFX PSU is significantly more quiet, it is almost inaudible below 400 Watts load. The small SPX-750 is absolutely compatible with Silent PC bulds, while the GX-850 V4 is absolutely unacceptable for Silent PC builds. Also the fan curve for the GX-850 V4 is absolutely trash. After closing a video game and going from around 400 Watts down to 80 Watts idle- it takes the fan like 2-3 minutes to stop spinning meanwhile the 92mm fan inside the small SPX-750 SFX psu stops spinning after like 10-15 seconds when closing the game and going from high load back to idle. I suspect it is the “new Seasonic OptiSink Design” that requires much more cooling. While it might have a bigger surface area for cooling in total, it lacks actual physical mass of bigger metal cooling heatsinks. Because of that it needs constant and active cooling compared to solutions with big aluminium heatsinks. All the marketing talk seems to be a bunch of bull, Quote:
“The eightfold increase in heat dissipation keeps the internals of the power supply cooler, eventually leading to improved product quality, long-term reliability, and more efficient operation.
The redesigned layout of the power supply components and its improved thermal performance creates versatility and allows the power supply to be safely installed in any orientation.
The OptiSink design is an eco-friendly solution that not only lowers the costs of material usage and production but also leads to energy savings in the long run.”
What it really means is- it is way cheaper for Seasonic to manufacture and because of that, they make more profit with the new OptiSink design. The downside is that it needs constant active air cooling due to lack of mass from big metal heatsinks, which are way more effective at cooling.
Needless to say I’ve returned the GX-850 V4, it’s absolutely terrible and unacceptable in terms of noise, I kid you not- the small SPX-750 is significantly more quiet. I made video comparisons as well, might upload them to YT later.

Nope, I don’t remember testing this unit! Basically I never heard of this brand before. Hmm, I will investigate this.
i’ve seen that the Maxwell Duke 1000W internals looks like 1stplayer NGDP 1000W https://photo.coolenjoy.co.kr/data/editor/2407/647933e3d3d50b746a68c7235da86ad64c5491bb.jpg this is your tearing down the ngdp 1000w https://hwbusters.com/wp-content/uploads/2023/09/top1-2.jpg
This new series is a disappointment
