OCZ ZT 650W Power Supply Review

The power supply uses a Yate Loon D14BH-12 fan which can generate up to 140cfm of airflow at around 48.5 dBa (2,800 rpm). This fan should be controlled to spin much slower than this however and we will test the noise emissions later in the review.

This is a Great Wall design, the same company who produce the ZX series for OCZ. There are several rows of black heatsinks separating components.

OCZ are using Teapo capacitors, rated 560μF, 420V, 105°C. Transient filtering starts at the AC receptacle with one X and two Y capacitors. We noticed that they aren't using a Metal Oxide Varistor which could be seen as a bad point of the design.

Capacitors on the secondary side are by Rubycon and Nippon Chemi Con. This design has extra ripple filtering in place with Teapo and Chemi Con capacitors on the modular PCB section.

The Game Awards have been around for well over a decade and at this point, the TGAs have cemented themselves as the biggest awards show for the industry. Keighley knows how to draw people in with promises of new game trailers and other announcements, leading to huge moments like Bethesda's reveal for The Elder Scrolls V: Skyrim, or Microsoft's Xbox Series X reveal. Winning the show's GOTY award is considered to be a badge of honour, so let's take a look back at the last ten GOTY winners and whether or not they deserved it.

  1. 100% modular is a selling point for sure. my current PSU is a mess, I hate it. need to get a new one later this year with a new coolermaster case.

  2. looks good. I bought a new corsair PSU last month, 750W. I felt 750W was safer than 650W as I might move to two 6970’s next year. Already have one. 650W is pretty much borderline as I know you should really be aiming for 40-70% of capacity under load. not 80-100%

  3. good all round design (if nothing out of the ordinary), nice select of caps too.

  4. Nice price.

  5. Its ok, some cheaper PSUs for the price, although you do pay more for modular.

  7. Might not be cost effective as you would like, but still you would like
