OK, so we've seen the graphs over on the previous page. Now here's the data that they were derived from.

Once again it's hard to really find any fault with the ToughPower XT's results. It puts out good efficiency levels, the exhaust temperatures are about average, the voltages at 100% load are highly respectable and the unit was completely unfazed by the cross-load tests. Furthermore, being able to run at 990w continuous is pretty damn impressive for a PSU rated at 775w and although the voltages were on a downward turn at this point, it felt like the unit could easily break 1KW if pushed a little further.

ATX specification
states that ripple should be no higher than 50mV on the +3.3v/+5v rails and 120mV on the +12v rails, and judging by those flat lines in the screenshots above the ToughPower XT 775w certainly had no trouble meeting these requirements in all of the tests. In fact, with the highest results recorded being 24mV on the +5v rail and 54mV on the +12v rail, the XT actually keeps the ripple at below half of what is required. Awesome.

Now that we've got a good idea of how it looks and how it performs, lets move on to the conclusion page and try to bring it all together...

The XT may have 25w more power than its 750w competitors, but does it have what it takes to impress OC3D?

Isn't the 775W version silver certified?

Stefan, I've been hearing mixed things. Apparently the website says silver, but the box most definitely says bronze

Maybe they re-submitted after the first batch went out. :/

Great review as ever Jim. Only you could make endless power supplies always seem fresh and interesting.

Love the new graphs too. Far simpler for people with less knowledge like myself to see the important data.

Great stuff.

Ah, OK.

It seems that the PSU Manufacturers tend to not advertise the gained 80+ certification but rahter one (or even two!) down.

It's understandable if you'll know something about it.

Anyway, there is a mistake in that review:

That's not the case.

If you'll take a closer look, you'll see 'HA1425M12B-Z' wich leads to Ong Hua, the same Ong Hua Fan you'll find in Corsairs HX750/850.

Hi. Can I start by saying great site and great reviews. As you can see by the user name I'm new to this and would really appreciate some clarity on the figures (as I must be missing something).

I have taken the figures from the 25% load line

........3.3v 5v +12v 5vsb -12v Totals

Volts 3.34 5.07 12.1 5.08 -11.98 13.61V

Amps 4.5 4.5 12.75 0.75 0.12 22.62A

Power = volts * amps = 307.8582 Watts

The output power shown in the table is 197 DC Watts

Could someone please explain what I'm missing

Many thanks

Hi Newbie, the reason you're arriving at a wattage higher than what is stated in the table is because you are multiplying the initial power draw against the resultant voltage output.

What the table actually shows is the amperage load placed on each of the rails, and the resulting voltage output by the rails due to the strain from the load.
