Great Wall Power Supplies Quality | Generated by AI
Question: How good are Great Wall (长城) power supplies?
Answer:
Great Wall Computer Shenzhen Co., Ltd. (长城电源) is actually one of the more mature Chinese PSU brands. It is not just a random domestic brand — it has been making PC power supplies for decades and has OEM experience.
For a normal desktop / AI workstation, a good Great Wall Gold/Platinum PSU is generally a reasonable choice.
The key is: judge the specific model, not only the brand.
Great Wall strengths
- ✅ Long history in PSU manufacturing
- ✅ Good domestic supply chain
- ✅ Many models use decent platforms (depending on series)
- ✅ Warranty is often competitive (some high-end models 10 years)
- ✅ Usually cheaper than equivalent Seasonic/Corsair models
For example:
- Platinum efficiency means the PSU wastes less power as heat.
- A 10-year warranty usually indicates the manufacturer has confidence in capacitor life and platform reliability.
Compared with international brands
Rough ranking:
Tier S:
Seasonic high-end
Super Flower high-end
Corsair AX/HX series
Tier A:
Great Wall high-end Platinum
FSP high-end
be quiet! high-end
Cooler Master high-end
Tier B:
Great Wall mainstream
Corsair RM/RMe
Thermaltake Toughpower
But some Corsair models are actually made by other OEMs (CWT, Seasonic, HEC, etc.), so the OEM/platform matters more than the logo.
For your MI50 / AI workstation case
Your situation is different from a gaming PC:
-
AMD MI50:
- ~300W GPU power
- server/workstation style
- HBM memory
- sustained compute load
A cheap gaming PSU is not ideal because AI workloads can run:
GPU 300W
CPU 125W+
motherboard + disks + fans 50W
----------------------------
450-550W continuous
A good:
- 750W Platinum
- 850W Gold/Platinum
is a comfortable range.
Example:
Wall power:
900W PSU @ 60% load
↓
GPU training 24h/day
↓
less heat
less fan noise
better capacitor life
My view
Your friend saying:
“以后装机买长城吧，长城白金牌，10年质保”
is reasonable.
For AI home lab, I would rather buy:
Great Wall Platinum 850W
+
stable motherboard
+
good cooling
than save 300 RMB on PSU.
The PSU is the one component that can kill:
- GPU
- motherboard
- SSD
and usually the expensive GPU is the thing you don’t want to gamble with.
For your MI50 build, a high-end Great Wall Platinum is actually a better match than many flashy gaming PSUs.
