Seasonic G Series 650W Power Supply Review

Having reviewed several units in the Seasonic G Series already we expected good results from the G650 unit, and we weren’t disappointed.

These power supplies are almost seen as a budget range for Seasonic, even though they are semi modular and 80 Plus Gold Certified. Technically they are impressive and none of the units we have tested so far have exhibited any weaknesses or related concerns.

Initially, the power supply won’t leave much of an impression because Seasonic have opted for a plain black paint finish. That said, most people with side windows do like a black power supply as it will fit in with any colour scheme. The paint is deep and can withstand rough handling. Fingerprints are the only issue, but a quick clean with a cloth removes them easily enough.

The unit was able to withstand quite extreme load variance and it could deliver over 730watts before shutting down. Seasonic do tend to over specify their power supplies which means they are capable of dealing with load peaks above their rated limit. Ripple suppression is very good, holding +3.3V, +5V and +12V well within industry rated tolerance guidelines.

All of the other G series power supplies we have reviewed to date have only had two PCI E connectors, but this one has four. This means it can handle a powerful Crossfire or SLi setup without a reliance on adapters.

You can buy the G Series 650W from ARIA for £99.95 inc vat.

Pros:

  • neat design.
  • modular.
  • quiet.
  • can deliver 730 watts.

Cons:

  • A lot of competition around £100.

Kitguru says: Seasonic deliver yet another quality power supply.
