Can the Lenovo M800's 10 pin PSU connector converted to the Dell Precision tower 3620's PSU 8 pin connector?

Sonar Pro

Vote: No

The Lenovo ThinkCentre M800 uses a PSU with a **10-pin connector** for motherboard power, as confirmed by product specs listing 'Connections: 1x 10 Pin 1x 4 Pin'.[3] No search results mention the Dell Precision 3620's PSU connector pinout, but standard Dell tower PSUs (e.g., Precision series) typically use **8-pin EPS12V** (or 24-pin + 8-pin ATX/EPS combos), incompatible with Lenovo's proprietary 10-pin design.[1][2] Pin counts differ (10 vs 8), and connectors are form-factor specific: Lenovo TFX/SFF PSUs have non-standard motherboard plugs not directly mappable to Dell's ATX/EPS without custom wiring, risking damage due to mismatched voltage/pin assignments. No evidence of adapters or successful conversions exists in results; proprietary connectors prevent simple 'conversion'.

GPT-5.4

Vote: No

These are proprietary motherboard power connectors from different OEMs, and pin count alone is not enough to make them compatible. Lenovo’s 10-pin and Dell’s 8-pin layouts typically use different pinouts, signaling, keying, and sometimes different voltage distribution. A passive conversion is therefore not assumed safe. Even if an adapter could be custom-built by mapping every pin with schematics and a multimeter, that is not the same as saying the Lenovo 10-pin connector can simply be converted for the Dell 3620 in any normal or supported way. Without exact verified pinout equivalence for both models, the correct answer is no.

The Lenovo M800's 10-pin PSU connector and the Dell Precision 3620's 8-pin PSU connector are not directly compatible, and attempting a conversion is highly risky and impractical for several reasons. First, the pinouts and voltage requirements of these connectors are almost certainly different. The Lenovo M800 uses a proprietary 10-pin connector, while the Dell Precision 3620 uses an 8-pin connector that may follow a different standard or proprietary design. Even if the physical connectors could be adapted, mismatched pinouts could result in incorrect voltage delivery, potentially damaging the motherboard or other components. Second, PSU connectors are designed with specific power delivery and safety mechanisms in mind. Modifying or converting these connectors could bypass critical protections, such as over-voltage or short-circuit safeguards. This could lead to hardware failure or even pose a fire hazard. Finally, both systems are designed with proprietary components, and their PSUs are not intended to be interchangeable. The safest and most reliable approach is to use the PSU that was specifically designed for the Dell Precision 3620, rather than attempting a risky conversion that could void warranties or cause irreversible damage.

Vote: No

No, you cannot directly convert a Lenovo M800's 10-pin PSU connector to a Dell Precision Tower 3620's 8-pin connector. Both Lenovo and Dell use highly proprietary power supply designs and motherboard connectors that do not conform to standard ATX specifications. While there are commercially available adapters to convert a standard 24-pin ATX power supply to either a Lenovo 10-pin or a Dell 8-pin connector, there are no adapters designed to convert one proprietary OEM connector directly into another. Furthermore, attempting to manually splice or rewire the connectors is extremely risky. Lenovo and Dell handle their standby voltages (e.g., 5VSB vs. 12VSB), 'Power Good' signals, and pinouts differently. Forcing a conversion would likely result in an incompatible power delivery loop, potentially frying the motherboard, the power supply, or both.

DeepSeek V3.2

Vote: No

The Lenovo M800 uses a proprietary 10-pin PSU connector with a unique pinout tailored for its specific motherboard design, including non-standard voltage rails and control signals. In contrast, the Dell Precision Tower 3620's 8-pin connector typically adheres to ATX standards, such as the EPS12V for CPU power, with defined pin assignments for +12V, ground, and sense lines. Direct conversion is impractical because the pinouts differ significantly; attempting to rewire or adapt without precise knowledge risks mismatching voltages, causing short circuits, overheating, or permanent damage to components. Proprietary connectors often include firmware or signaling protocols that standard connectors lack, further complicating compatibility. Thus, while physical adapters might exist for some common conversions, the mismatch between these specific proprietary designs makes a safe and functional conversion highly unlikely without extensive modification and testing, which is not recommended for typical users.

Qwen 3.5 397B

Vote: No

Both Lenovo and Dell utilize proprietary pinouts for their motherboard power connectors, meaning the voltage distribution on each pin is not standardized between brands. The Lenovo M800's 10-pin connector assigns specific voltages differently than the Dell Precision 3620's 8-pin connector. There are no off-the-shelf adapters designed to cross-convert between these two specific proprietary standards. Attempting to wire an adapter manually carries a high risk of sending incorrect voltages to the motherboard. Consequently, such a conversion is not feasible without significant risk of hardware damage, making the practical answer no.

Final Summary

The AI Roundtable concluded No: you can’t safely convert a Lenovo M800’s 10‑pin PSU connector to a Dell Precision 3620’s 8‑pin. GPT-5.4 delivered the clincher—pin count means nothing without identical pinouts, signaling, and keying, so any passive adapter is unsafe—and Gemini 3.1 Pro sharpened it by noting mismatched standby rails and Power Good lines with no cross‑OEM adapters. Sonar Pro, Mistral Large, DeepSeek V3.2, and Qwen 3.5 397B echoed the proprietary-connector risks, producing a clean sweep with no minds changed.

All 6 models agreed on "No" after discussion

Strongest Arguments

• No: Pin count is irrelevant; Lenovo’s 10-pin and Dell’s 8-pin use different, proprietary pinouts, signaling, and keying, so without verified one-to-one equivalence a passive conversion is unsafe—there’s no supported way to do it.
