Skyhawk Eagletech Pantherpower

[370forlife]

Friend has one of these. About the only good skyhawk power supply made. Has problems where his computer will shut off after a while.

I am not sure if these units have overtemp protection. Doubt it. He is only running a 7800gt with a amd athlon 64 something or other, maybe a dual core, but not much. JG did a test of this power supply, and he ran it up to about 450W, and it kept under 30mv the entire time. But it had tocon caps in it.

I have two questions, would the shutting off be caused by bad caps, or something else?

Re: Skyhawk Eagletech Pantherpower

if the caps are overheating and it has thermal shutoff, then yes. if not, then it could be something else in the power supply or the ripple is killing the mobo/cpu.

i swear that skyhawk makes the world's worst "wannabe" power supplies. cmon, skyhawk sounds cool, but their crap sure aint.

Wow... that's a mouthful.
I wonder if there's any other "cool" animal names they can work in there.

LOL!

You mean the Zoopower?

Haha that would go great with my Thunder Cougar Falconbird supply .

i have one of those myself.
its not very portable though.
stays bolted to a big chunk of cast iron.

Re: Skyhawk Eagletech Pantherpower

There is no such as overheating caps and shutting down, total bunk. They die really short life if running hot, and not all SMPSes have thermal sensing and is poor, and some don't use it for that, it is merely for the fan speed.

I have not seen a SMPS that you can buy over the counter with thermal shutdown till you get to 70 and above dollars range and that's not common. Yes sure in 600W plus and that retail for about 80 and above, but not all do have it by default, just for fan speed.

The serious SMPS used in rack stuff will have it but that is serious penny in around 100 to 150, even 200 dollars range.

Well, actually, it has overtemp protection. OW did the review of it, and he says that it is over sensitive. His shuts down powering a couple of fans, so I might just rewire the fan to run constantly on 12v.

Re: Skyhawk Eagletech Pantherpower

If it's oversensitive change the value of the thermisistor it's screwed to the heatsink.

Re: Skyhawk Eagletech Pantherpower

at least its not under-sensitive. then, there would be flames shooting out the back of the computer... and this time you couldnt't blame the p4 cpu or crappy cpu cooler.

Good think I decided to take a few out of some old bestecs and all those proprietary deltas. How can I tell the value?

damn data base error double post...

Re: Skyhawk Eagletech Pantherpower

It might be easier to take an assortment of fixed value resistors (or a pot, if you have one) and put that in series/parallel with the thermistor. Then you wouldn't have to worry about goofing up the thermal contact between the thermistor and the heatsink. And you wouldn't have to worry about figuring out if it's a PTC or an NTC and getting the appropriate value. You could rip apart old power supplies for resistors, or you can usually find assortments pretty cheap on ebay.
