PSUs are the most essential and underrated pieces of the puzzle when building a PC, and choosing the right one for your needs could go a long way as you can save electricity and your PC from potential harm. As PC components get more power-hungry over time, it is also important to consider future upgrades and get a higher wattage power supply that can take those upgrades over the years.

There are a variety of power supplies out there, but the fully-modular options among them are the most preferred as they’re versatile. When choosing a good power supply brand, XPG might not be the one that comes to mind. When XPG reached out to us, I thought, “Wait. XPG makes Power Supplies?” Thanks to XPG for sending the PSU; here’s our review of the Core Reactor 850W, a beefy power supply after the 1000W and 1300W variants that ticks most boxes.

XPG Core Reactor 850W Review

Let’s get the pricing out of the way first. The Core Reactor 850W costs $130/Rs 8,000 on Newegg. The lower 750W and 650W variants cost $110 / Rs 7,500 and $100 / Rs 7,000, respectively.

Unboxing Experience

The unboxing experience was great. The PSU came well protected with thick protective packaging on the inside. It was also wrapped around with lots of bubble wrap, which I think saved our unit from damage, as it looked like the box went through a lot of abuse, and hence the edges were crumpled. Thanks, Amazon.

The PSU took over 70% of space in the box while the cables (Lots of them) consumed the remaining. The cables came in a good velcro strap bag with XPG branding at the front, which made the unboxing experience a delight. The cherry on the top was the stickers, which I quite liked. Overall, a huge thumbs up for great packaging.

Build Quality

The build quality of the Core Reactor 850W is solid. The robust metal housing encases a 120mm cooling fan with the Core Reactor branding on both sides. The CPU & VGA, Motherboard, PCIe, and SATA/Molex pins are all neatly labeled.

The build quality of the included cables is also excellent. They’re braided, and the plastics around the connectors feel solid. Speaking of cables, here are all of them XPG included in the box.

  • 2 x CPU cables
  • ATX Connector 20+4
  • 1 x 4-pin Molex
  • 3 x SATA connectors
  • 2 x 6+2 PCIe connectors (650 +150mm)
  • 2 x 6+2 PCIe connectors (650mm)
  • AC Power cord
  • Screws

The rig that we tested the PSU on:

  • Zotac GeForce 1650 Super 4GB
  • Gigabyte B450M Gaming
  • Ryzen 5 3600 with stock AMD cooler
  • Three 120mm Deepcool fans
  • 2 x Corsair Vengence DDR4 3200 MHz sticks
  • Two SATA SSDs 128GB+1TB (Crucial BX500 and Kingston A400), 512GB Silicon Power M.2 NVMe SSD, and 1TB Seagate BarraCuda HDD.

The noise levels were pretty good. At around 30 decibels, it’s not the quietest PSU out there but does better than other PSUs like the Cooler Master V850.

The fans spin quite fast at a full load of our PC (at around 1100 RPM if the speed curve on the box is something to go by), but the noise levels remain low, if not 2-7dbs higher. Similarly, the heat level also remained pretty low. Since the PSU is 80 Plus gold rated, it should do great on the efficiency front (Over 90%).

Speaking of heat, both the in and out temperatures on idle stayed at around 35℃. However, during heavy gaming, the temperature inside the chassis jumped to 42℃, and the outgoing temperature to 46℃, which is pretty good.

XPG Core Reactor 850W: Final Words

Overall, the Core Reactor 850W is a great PSU for anyone who needs a PSU for demanding needs or wants to upgrade PC components in the future (People who are waiting for the 3000 series to get cheaper once the NVIDIA 4000 series is out, I’m looking at you :)). It comes with all the protection you’ll need and runs efficiently, thanks to the 80 Plus Gold rating. Priced at around Rs 8,000/$130 at the time of writing this, it is one of the cheapest fully-modular power supplies you can get.
