OC3D Review: Thermaltake ToughPower XT 775w

[tinytomlogan]

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.

[Stefan Payne]

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.
