AI Verdict

This bundle offers a 240mm AIO liquid cooler with ARGB lighting and an 850W 80+ Gold fully modular power supply for mid-range PC builds.

Situational Fit

This combo is a situational fit for budget-conscious builders who need both an AIO and PSU. The 240mm liquid cooler provides adequate cooling for many mid-range CPUs, and the 850W 80+ Gold PSU offers sufficient power. However, the PSU's reported reliability issues and lack of ATX 3.0 compliance mean it's not a universal recommendation.

If you're building with a high-end CPU or a GPU requiring a 12VHPWR connector, look for an AIO with a larger radiator (e.g., 360mm) and an ATX 3.0 PSU with native 12VHPWR support.

The MWE Gold 850 V2 is a fully modular power supply, which significantly simplifies cable management within a PC case.

Best For

  • PC builders on a budget needing both CPU cooling and power supply for a new system.
  • Gaming PCs with mid-range CPUs (e.g., Ryzen 7 5700X, i5-12600K) and GPUs that don't require a 12VHPWR connector.
  • Users prioritizing ARGB aesthetics in their build without spending a lot on an AIO.

Not Recommended For

  • High-end CPUs like Ryzen 9 7900X or Intel i9, where a 240mm AIO might not be sufficient for optimal cooling.
  • Users who need the latest ATX 3.0 standard and native 12VHPWR support for current-gen GPUs.
  • Silence-focused builds, as the AIO fans can be loud at higher RPMs and the PSU lacks a zero RPM mode.

Watch Out For

  • The MWE Gold 850 V2 PSU has a history of dead-on-arrival units and high failure rates reported by users.
  • The AIO's fan screws with 6.4mm-tall finger grip heads could cause installation issues in cases with tight motherboard clearances.
  • The PSU's fan lacks a zero RPM mode, meaning it's always spinning and can become audible under high loads.
  • The MasterLiquid 240L Core's performance can be 5°C behind top-tier competitors, even with its budget price.
  • The PSU is ATX 2.41, not ATX 3.0, which means it doesn't have the dedicated 12VHPWR cable for newer GPUs, requiring an adapter.

What Buyers Say

The most surprising finding is the recurring concern about the MWE Gold 850 V2 PSU's reliability, with multiple users reporting dead-on-arrival units and high failure rates. Despite this, the MasterLiquid 240L Core AIO generally performs better than expected for its price, effectively cooling mid-range CPUs. The bundle's appeal lies in its budget-friendly nature and ARGB aesthetics for the cooler. However, the lack of ATX 3.0 and a native 12VHPWR connector for the PSU is a drawback for newer builds.

“Man, I really wanted to like this combo because the price was right, but that PSU dying on me after a month? Not cool. The AIO looks sick with the RGB though, keeps my 5600X chilly, but I'm definitely swapping out that power supply ASAP.”

Common Praise

  • The MasterLiquid 240L Core AIO offers surprisingly strong cooling performance for its price.
  • The AIO's ARGB lighting on the pump and fans looks appealing and is customizable.
  • The MWE Gold 850 V2 PSU's fully modular design makes cable routing much easier.
  • The AIO includes high-quality CryoFuze thermal paste. [Feature Highlights, 12, 13]
  • Installation of the AIO is generally straightforward.

Common Complaints

  • Many users reported the MWE Gold 850 V2 PSU having high failure rates or being dead on arrival.
  • The MWE Gold 850 V2 PSU is ATX 2.41 and lacks a native 12VHPWR connector for modern GPUs.
  • The AIO's fans can get loud and 'rowdy' at higher speeds.
  • Some users experienced coil whine from the MWE Gold 850 V2 PSU.
  • The AIO's build quality is sometimes perceived as lower compared to more premium options.

Ownership Tips

  • The AIO's ARGB lighting is bright and syncs well with motherboard software.
  • The PSU cables are flexible enough for routing, but the lack of a 12VHPWR cable is a real pain for new GPUs.
  • The AIO pump is generally quiet, but the fans can ramp up noticeably under load.
  • The included CryoFuze thermal paste is a generous amount, enough for multiple applications.
  • The PSU's fan is always on, which might be a minor annoyance in a very quiet room.

Frequently Asked Questions

Is the MasterLiquid 240L Core a liquid cooler or an air cooler?

It's a 240mm All-In-One (AIO) liquid cooler, despite some conflicting product specifications. It uses liquid to transfer heat from your CPU to a radiator, which is then cooled by two 120mm fans.

Is the MWE Gold 850 V2 PSU compatible with the latest GPUs?

The MWE Gold 850 V2 is an 850W 80+ Gold PSU and can power many modern GPUs. However, it is ATX 2.41 and does not include a native 12VHPWR connector for the newest high-end graphics cards, so you'll need an adapter if your GPU requires one.

How quiet is this combo?

The AIO's fans can be quiet at lower RPMs but become quite audible, or 'rowdy,' at 75-100% speed. The PSU's fan is always spinning as it lacks a zero RPM mode and can be heard under high loads.

Does the AIO come with thermal paste?

Yes, the MasterLiquid 240L Core includes a full tube of Cooler Master's CryoFuze thermal paste, which has a high thermal conductivity of 14W/mK. [Feature Highlights, 12, 13]

Is the MWE Gold 850 V2 PSU reliable?

User feedback on the MWE Gold 850 V2 is mixed, with some reports of high failure rates and dead-on-arrival units. It's listed as a B-tier PSU on some lists, but concerns about its reliability have been raised.

Can this AIO cool a high-end CPU like a Ryzen 9?

While it performs well for a budget AIO, a 240mm liquid cooler like the MasterLiquid 240L Core might struggle to optimally cool very high-end CPUs such as the Ryzen 9 7900X, which might benefit from a larger 360mm AIO or a more robust cooling solution.

Buying Guide

When you're looking at a power and cooling bundle like this, you're essentially getting two critical components for your PC. For the cooler, you need to think about how hot your CPU runs and if a 240mm liquid cooler is enough to keep it cool without sounding like a jet engine. For the power supply, it's all about making sure it has enough wattage for your current and future components, and that it's reliable enough not to cause headaches down the line. Don't just look at the numbers; consider the actual user experiences.

wattage (850W)

This is how much power the PSU can deliver. Think of it like the horsepower of a car; more wattage means it can handle more powerful components, especially your graphics card and CPU, and gives you room for future upgrades without needing a new PSU.

rating (80+ Gold)

This indicates the power supply's efficiency. An 80+ Gold rating means it converts at least 87% of the power from your wall outlet into usable power for your PC, wasting less energy as heat. It's like getting better gas mileage for your computer.

fan_size (240mm)

For the AIO, this refers to the size of the radiator and the fans. A 240mm radiator has two 120mm fans. Larger radiators (like 360mm) generally offer better cooling performance, especially for hotter CPUs, but also take up more space in your case.

modular (Modular)

This describes the power supply's cables. A fully modular PSU means you only plug in the cables you need, making your PC build much cleaner and improving airflow inside the case. It's like having custom-fit cables instead of a tangled mess.

Alternatives

If this bundle doesn't fit, search for an ATX 3.0 power supply with a native 12VHPWR connector for newer GPUs, and consider a 360mm AIO liquid cooler or a high-performance air cooler for demanding CPUs.
