Gpu not starting without power (single click noise from power supply unit)
I purchased a working RTX 3070 GPU from a friend and connected it with all new components. The PC functioned properly for five minutes before experiencing a random shutdown, which then restarted but again shut down after five minutes. This time the system does not boot at all. I notice a clicking sound coming from the power supply unit. I chose to disconnect the GPU cables and observed that the PC lights up only when one cable is removed. Specs: Mobo -Msi B450M, RAM -8×2 DDR4 3200MHZ, GPU -RTX 3070, PSU -DEEPCOOL DQ-750M, Storage -1TB NVMe, 2TB HDD, CPU -Ryzen 3600.
complete system specifications available. brand and model of the power supply included.
Here are some suggestions.
Check everything carefully.
Remove any extra parts, including extra RAM or SSDs. Test again. Add one component at a time and retest. Keep going until you find the faulty part.
Make sure your power supply is fully seated in the PCIe slot.
Verify all power cables are correct and properly connected to the right ports on the power supply, ensuring they’re fully inserted.
Another possibility is that your BIOS might be corrupted—you may need to reset it.
The Deepcool DQ750M-V2L power supply is typically viewed as a C tier or low priority C tier PSU according to the list on Cultists Network. This assessment comes from its status as a mainstream platform adapted from CWT with some changes, and the scarcity of direct reviews for this exact model. Although it carries an 80+ Gold certification and offers full modularity with a 10-year warranty, certain users have mentioned problems such as a burnt smell or high-pitched noise when unboxing.
A more detailed overview includes:
- Tier: C tier, with a lower priority classification due to limited reviews.
- Platform: Based on the CWT GPX platform with modifications.
- Features: Certified 80+ Gold, fully modular, comes with a 10-year warranty.
- Notes: Some users have experienced issues like burning odors or unusual sounds upon opening. Others compare it favorably to higher-tier models (B tier) for its performance and reliability.
Recommendations suggest using this PSU for systems with dual 1070s or similar components, rather than top-tier cards such as 2070s or 2060s. The low tier C rating may reflect an attempt to boost sales by offering a 10-year warranty on a less-than-ideal unit.
It’s also mentioned that purchasing from a friend raises questions about their return policy. A previous PSU (an Aerocool 850W) failed within days, even with lower power components, indicating potential quality concerns. The author advises against relying on anecdotal feedback and suggests sticking to well-known brands like Corsair, Seasonic, EVGA, or Superflower for better reliability.
Additionally, the text highlights that transient power spikes—brief increases in power consumption during GPU transitions or heavy loads—can strain a PSU. These spikes are common with RTX 3070 GPUs and require a quality power supply to maintain stability.
For users considering upgrading, testing the GPU in a system with a similarly unreliable PSU may be necessary, but it’s wise to opt for a dependable model to avoid further complications.
