In the era of quad cores and soon to be quad graphics cards, 650W might seem like a puny power plant to keep a system running. Thankfully for all our wallets, that’s not the case. The latest enthusiast graphics cards from both ATI and Nvidia are delivering similar performance to the high-end cards and have much lower power requirements to boot.

There's also at least one 45nm CPU out already offering quad-core performance in the same power envelope as previous 65nm dual-core chips – mid range PSUs like the Enermax 650W should cope well into the future.

Apart from stable rails and not blowing itself up, one of the most important factors to consider with a power supply is energy efficiency, especially if you’re like me and leave your PC on because you’ve a lot of stuff open or it’s still processing data while you’re away.

That’s also why we keep a close eye on the 80Plus programme which is now also part of Energy Star 4.0 compliancy. The organisation behind 80Plus independently measures a PSU’s efficiency at 20, 50 and 100 percent to check it’s consistently higher than 80 percent efficiency across the range. bit-tech does a similar test, but only at 50, 75 and 100 percent load.

Both the Enermax Infiniti 650W and 720W are certified by the 80Plus programme and come with labels on the box indicating this.

In the Box

  • Cable sleve
  • Power cable
  • Modular cables
  • Maunals
  • Four case screws
  • And a pair of stickers
Enermax packs the PSU well enough; while it’s not thick foam, the bubble wrap is sufficient and everything is neatly packed rather than stuffed in.

The box itself is, as usual, remarkably informative and contents list is what you need to get going but at the same time it’s also the most basic of packages you’d expect. That is, unless you’ve always wanted some Enermax case stickers.
