SkyHawk Power One

[pfrcom]

Got this in a box of parts that I bought

Felt quite heavy, was surprised to see it's a SkyHawk - last SkyHawk I had, just about needed tethering to stop it floating away

What's your opinion of its quality, or otherwise ?

I'm planning to replace the bulging secondary caps, then connect it up to a motherboard and etc. that don't have much value

This is its cover assembly, showing the second fan

Re: SkyHawk Power One

Skyhawk designs (most) of their own units. Expect it to do 400W pretty well in spec, might be able to do 500W for a bit but ripple would probably skyrocket and voltage stability might suffer.

Re: SkyHawk Power One

The filtering looks quite healthy and the main transformer is big - i'd say with good quality cap replacements it'll do 500W in spec.

Re: SkyHawk Power One

Surprising for a SkyHawk. The last one I saw was a gutless wonder

Re: SkyHawk Power One

I'm sure I had a CIT 450W with the exact same heatsinks...

Re: SkyHawk Power One

Isn't this actually a Solytech? - L&C/Deer/Allied/ et. al.


What is the board next to the 2nd fan? Pics please.

Re: SkyHawk Power One

Skyhawk designs and builds their higher end units, their low end units are hardly designed though. Just the general leadman/sunpro look-a-like gutless wonder units.

Hope this satisfies your curiosity

Tom's Hardware review mentions an audio standby feature - "You insert an audio CD into the CD-ROM drive. After pressing the drive's play button, the CD is played back via headphones or speakers connected to the slot plate."

The cable coming out of that board has a Molex connector on the end, presumably to provide always-on power to a CD drive

Re: SkyHawk Power One

Excellent! Explains the "Audio Standby" column on the spec plate.

Thanks!

Re: SkyHawk Power One

I replaced the 5 bulging caps with ones recycled (and tested) from scrapped motherboards

2 x 3300uf 10v GL replaced by Panasonic FJ 3300uf 6.3v

2 x 4700uf 10v GL replaced by Chemicon KZE 4700uf 6.3v

1 x 4700uf 16v Metacon replaced by Chemicon KZE 4700uf 6.3v

The last one was carelessness - only when disposing of the old caps, did I notice one was 16v instead of 10v

That replacement didn't do anything horrible after about half an hour of testing

What's the worst that could happen - just the capacitor fail, or something more serious ?

Re: SkyHawk Power One

you could have been luck y and it was on a 5 or 3.3v rail. unless you know for certain i would still change it out thouhg!

Re: SkyHawk Power One

The cap will fail shortd if overvolted. This will cause the PSU to shut off.

Re: SkyHawk Power One

or blow up if its crp

Re: SkyHawk Power One

I finally got around to replacing the 4700uf 6.3v cap I'd put in, where the original was 4700uf 16v

Trouble was, it wouldn't fit - the positive lead could get to the PCB, but the negative couldn't

I hope the electronics gurus here aren't too horrified, but I chose to extend the negative lead

Re: SkyHawk Power One

Then put shrink tube over the two leads

Re: SkyHawk Power One

Here it is, dominating the area, but it works

No wonder the original didn't last - contrast its size with the replacement in previous two postings' pictures
