and the CX400 slots in nicely below the well-regarded HX520.

surely it should be ‘slots in nicely below the VX450w.’?

The California-based manufacturer states that the engineering know-how that comes from developing high-end units such as its HX1000 has allowed it to create a “best-in-class power supply for mainstream users”.

This has me scratching my head a bit. Isn't the HX1000 made by CWT (yes, the same people who made my £28 XClio PSU), not Corsair? In fact, aren't all of their previous models made by either CWT or Seasonic?

I'd love to know how that allowed Corsair to create a best in class power supply.. if indeed they have even created this one.

tis made by seasonic

So in fact it's not even made by the same people who made the HX1000! What a confusing press release.

Why are “low end” PSUs 400W? My systems have C2D's OC'd to 3.2ghz, HD3850s, 2Gb and HD and consume at spikes up to 175W when booting, 150W when running Orthos and 130W when gaming. Idles at 70W. Thats all at the wall.

I'd like a 250W PSU that was energy efficient. All 400W+ systems are never at peak efficiency when so lightly loaded.

due to the amperage on the rails?

But then I guess the cost of a decent 250W compared to a 400W is minimal.
Even those laptop power supply that gives 95W cost a hell lot of money.

Suprised how little power those C2D use. My desktop eats 80W more at full load / 90W idle than yours. But then I got a hell lot more HDDs.

How do you monitor what the total power used is?

you use one of these http://www.ecofreak.co.uk/products/19/58/Plug-In-Mains-Power-and-Energy-Monitor.html:)

and that gives you the total that the comp is pulling from the wall.

No way of monitoring it via software?

either use a plug monitor or go by reviews, see what they get on the total wattage on a similar pc.
I need to get one of them plug things but im waiting for one at £5 :P.

Surely a good thing.
There is poor decent quality competition at the lower end.
Still I guess it really could be down to who manufactures the part and the warranty.

A product ill probably look at as well as the cheaper Hipers.
