here's a more professional review,
http://www.silentpcreview.com/Seasonic_X650

I know it's expensive, but look at the corsair, against the retail price, it's only $20 more. I know, rebate...but still. Plus, the x-650 is the only modular Gold PSU you can buy right now that's 650W.

edit-the other options are Enermax's Pro-87 and Modu-87 line. These are gold. The pro are non-modular, the modu, obviously modular. check around for availability, they're pretty new, but also very quiet and high high quality. Enermax and Seasonic are the only brands I'd buy.
This is probably what I'm going to get then, thanks.

However, for a new PSU, and a single card setup, I'd recommend a ~550W+ PSU (because of Fermi's ridiculous power draw).

or if you want modular:

Review, here.

Great quality PSU. No need for a 750W if you're just using a single card.

Edit: Here is a JonnyGuru review for the X650. An amazing PSU.
Those are only Bronze certified...

What other programs read voltages on the powersupply?

Everest, Speedfan. That's what I know of. Most enthusiast boards come with some kind of software monitor. Also look in the BIOS PC health section.

There's only really the SeaSonic X650, X750, AX750/AX850 (which aren't released) that are worth bothering about, I was just giving more options.

You do know that efficiency doesn't necessarily mean higher performance, right?

And you don't use software to measure voltage. You need to use a digital multimeter. If your 12V rail was at 4.99V, you wouldn't be posting this, like I said.

Edit: the reason software voltage reading is useless is that it doesn't counter for things like line in resistance.

Enermax has the Pro87 line and Modu87, both are listed on newegg. Only problem is that for the Modu series, they aren't releasing the 500W just yet, only 700 and up for now.

Yeah, they're not hugely amazing.

There's a trade-off for efficiency for things that actually matter, like voltage ripple and regulation.

Actually, they're very good in that area too. These are top of the line units from well known manufacturers, so they aren't going to skimp.

Proof of that ryboto? Just because they are a well known manufacturer doesn't mean they are going to be perfect. Listen to meti, he knows what he is talking about.

Check the other review for the seasonic, but from the same site,

regulation-
Quote:
The Enermax Modu87+ is no exception — it was nearly always within ±2% on any line. With the exception of the cross-load test (which is strenuous), the +12V line stayed above the specified +12V at all times.
ripple-
Quote:
Ripple on the 12V line was a little higher than we've seen in other top units, but still well within spec at <47mV all the way to full load. The 5V and 3.3V lines exhibited very low ripple, under 17mV and 12mV at all levels.

I don't think meti has enough rep to listen to him yet

They're good, but why would he spend all the money on one if he doesn't need anywhere near that amount of power?

It also looks rather tacky and horrible, IMO... not that that's really worth anything, since appearances are subjective.

Go with one if you feel like spending more money than you need to on a power supply that's way overkill for your rig.

edit: the SPCR review is rather... flawed. He's testing at room temperature.
