NZXT C650 provides dependable energy

NZXT is finest recognized for its lineup of premium PC circumstances. Like different distributors (assume Fractal), the corporate is trying to additional develop product strains, together with motherboards and energy provides. Whereas NZXT could also be new to the PSU sport, the producer NZXT determined to accomplice with is not.

Opting to go along with Seasonic is a brilliant transfer for NZXT, and it resulted in a superb sensible collection of PSUs, which we beforehand reviewed. Whereas these items carried out effectively, not everybody desired the sensible options with software program integration, therefore the brand new C collection of PSUs.

We now have the C650 in for testing and because the mannequin title implies it is a 650W unit. Design-wise, there’s probably not a lot to say. It is a slab of black metallic, which is the norm for PSUs lately, however it’s modular, making it a super resolution for energy in a system with few inside parts, permitting you to make use of solely the cables required.

There is a zero RPM fan-mode button on the rear, which permits the unit to stay silent when not being pushed onerous sufficient. As soon as you’ve got reached the set demand and thermal thresholds, the 120-mm fan spins up, but it surely’s not fairly as loud because the NZXT E collection PSU.

To essentially push this PSU to the check, I utilized two PC builds, one an overclocked quad-core Intel Core i5-6600Ok and one other rocking the brand new 12-core AMD Ryzen 9 3900X (105W on its on). Each programs additionally had 32GB of RAM, an overclocked RTX 2070, and M.2 NVMe drive. Pushing this factor in intense functions, benchmarks and video games confirmed no points. I noticed secure energy supply, as anticipated.

For cabling, NZXT consists of the next:

  • 24-pin ATX
  • 1x 12v P8 (2x P4)
  • 4x PCIe 6+2-pin
  • 2x SATA (8x SATA)
  • 2x Peripherals (6x MOLEX)

That is greater than sufficient to hook up the most recent parts you will want in even a extra critical gaming rig.

On paper, the C650 has greater than sufficient grunt to maintain the lights on, even whereas beneath load. You have acquired 80 Plus Gold certification, which means it exceeds 90 p.c effectivity whereas at 50 p.c load, getting extra efficiency per watt as proven in our testing. Constructed with all-Japanese capacitors, the C collection can also be constructed to final thanks partly to the quite a few put in protections.

What you may dislike in regards to the NZXT C650

The one main criticism with this PSU is the cabling. It is a bit of on the brief aspect for the SATA connections, which means it could be a bit of tight if you happen to’re making an attempt to hook up a number of gadgets that use SATA energy (SSDs, as an example) utilizing a single output.

One other potential hit for some often is the value, however paying a premium in your PSU is not a destructive due to how essential this part really is in any PC construct. It is a bit of on the costly aspect, however so too are different PSUs from respected manufacturers with the same construct high quality and energy supply.

Do you have to purchase the NZXT C650?

There are many PSUs obtainable, however solely branded fashions from respected distributors needs to be thought-about, and even then it comes right down to effectivity rankings, reliability, stability, and value. NZXT’s E collection of PSUs are excellent throughout the board, however not everybody wants (nor desires) the software program integration.

That is the place the brand new C collection suits into place, providing related specs backed by a prolonged guarantee from two dependable and established manufacturers inside the PC trade. Whether or not you want a 650W, 750W or 850W energy unit, this household of PSUs are value contemplating to your subsequent PC construct.

Using high-quality Japanese capacitors and different parts, the secure supply of energy throughout the rails, and the power to have the unit function with out the fan spin up makes it a compelling selection. The 650W mannequin is good if you happen to plan on making a single GPU system (as much as round an RTX 2080 Ti) and in comparison with the E collection, you save a bit of cash within the course of.
