Dell GX270 Power Supplies

[kenpospeed]

I have some GX270 p/s that have no power to them

Any suggestions on where to start the troubleshooting at for these units?

Start at the fuse.

Re: Dell GX270 Power Supplies

Which supply do you have: Lite-On, Newton, or HiPro. SFF, Slim Desktop, or Tower?

Re: Dell GX270 Power Supplies

Thanks, ya I didnt even think about testing those since they visually looked fine, but that seemed to power it back up

It's the slim desktop type

Re: Dell GX270 Power Supplies

Also I was wondering if you guys knew where I could get some new fans for these, the one on here doesnt spin anymore and I tried cleaning it.

esp in the sff psu fan failure is the most common cause of death.
it stops and the caps cook.
get a quality replacement.

GX270 PSUs have a hamster wheel fan, not a standard one, so finding a replacment may not be easy. The last GX270 PSU I opened had a nidec fan, so it kind of surprises me that it failed here.

Re: Dell GX270 Power Supplies

i thought the hamster wheel was the case fan in the slimmer units...

Couple of them use it in the psu as well.

Here's a GX270 PSU.

Re: Dell GX270 Power Supplies

They're called squirrel cage fans... or, more appropriately, centrifugal blowers - http://en.wikipedia.org/wiki/Centrifugal_fan

c_hegge - that's not the only type of PSU used in the GX270's. The smallest ones had a standard bladed fan.

I know what they're really called. I just call them that because they look like a hamster wheel.

What I didn't know is that there was more than one type of GX270 PSU as the one I posted before is the only type I've ever seen or heard of.
