I guess they are a new company that started at CES awhile ago anyone think that they will be any good?

Judging by this:

I'd question whether it's worth buying. They rate the -12V rail as 72W? WTF? on top of that the combined rating for the -5V, 5VSB and -12V is 202W? That's just crazy.

Any PSU lacking certification logos as this one does goes on my not recommended list until I can make sure the innards are decent.

No thinking necessary:p
I have no experience with that model, but I can tell you that my boss likes to order sub-$30 cases from Tiger, and some of them include 350w models from
Power Tek, put it this way, I would sooner use a Okia before ever thinking of
useing one of those shit bombs for a build;)

Not to even mention their complete lack of math skills... 12 volt rail with maximum output of 42 amps can actually put out 685 watts; -12 volt rail with 0.6 amps can put out 72 watts; and 3 + 72 + 10 watts equals 202 watts :crazy:

Some can possibly be explained by the fact that they are peak values (though on one figure it is mentioned, so you'd expect to be mentioned on other peak figures as well), but still there are too many inconsistencies with those figures; I'd steer clear from that thing.

the box hype sounds good though ..Industrial grade components

The 750W F5 is a very good psu. I've put them in around ten gaming rigs with crossfire, sli, sata's, etc., and there has never been a problem.

QFT (quoted for truth) :)

I'd put $130 into a Corsair HX620 because it is a known value.

erocker, welcome to this board. Let us know how those 10 units do over this coming summer. :cool:

For the PMP contest, you might get a "good" 650W back;)

Ok, let's see

The 120/220 switch on the back = no aPFC
-12v=0.6a. That SHOULD = 7.2w. They're 10x off
-3 + 72 + 10 (on their label) = 85. They're 117w off.
-3 + 7.2 + 10 (actual) = 20.2. They're 181.8w off
3.3v * 28a = 92.4w.
12v * 42a = 504w.
92.4 + 504 + 160 = 756.4, for their MAX.
756.4 + 20.2 = 776.6. For the Actual MAX.

885w+202w (label, for peak) = 1087
700/1087 (theoretical difference) = 64.4% between peak and "coritinious"
776.6*64.4% = 500w "coritinious

Assuming that their psu is actually capable of what the label says.
