Lenovo Thinkstation S20 - PSU

[Koldov]

Well there's a few threads this post could have gone (annoying things, I'm looking at you)...

 

After having some work done in the house (meaning everything in storage for a few weeks) I finally got my 'man-cave' room back. Guitars and amps all back in, desk and computers all set-up...

 

Turned on one of the PCs, got into post and pop! Dead.... Took the PSU out and into work today, plugged into the tester but no joy.

 

Spec from the label (no well-known/major manufacturer name):

 

625w - Bronze

+3 +5 = 175w MAX

+12 = 475w MAX

TOTAL = 610w

 

It has the following connectors:

 

1 x floppy

5 x Sata

1 x 10 pin

1 x 6+2 pin

1 x 6 pin

1 x 4 pin

1 x 24 pin

 

The sticking point seems to be the 10 pin CPU connector:

I bought this from @ICTDirect_Dave years ago and haven't actually built my own in ages, so to save me going down a major internet search rabbit hole... does anyone know what I need to replace it with? I thought I had a spare, but when I actually found it I realised it was an old Corsiar CX500 (so only 500w) and doesn't have a connector with 10 pins...

 

Links would be helpful, name brand and a Black Friday deal for extra points!

There’s a couple on Ebay, https://www.ebay.co.uk/itm/115383259402 . Adapting a regular desktop PSU may be possible with a 24 pin piggyback to the 10 pin but it’ll pull a fair amount of current over that.

Thanks, yeah I'd seen the ones on ebay (and various web-stores I've never heard of, apart from aliexpress.com lol)... I've hacked the connectors of a few PSUs in my time, but really don't fancy the hassle/danger of killing it completely anymore these days (in fact I've got to hope the whole thing isn't fried as it is).

 

Given the age of the PC and therefore the age of the components I was hoping not to go second hand/refurbished if I could help it as the replacement is just as likely to go pop, but it seems there is very little choice.

 

I've only seen a couple of threads on other forums and no solid advice unfortunately, seems the 10-pin connector is quite rare (due to the age and possibly actually unique to Lenovo, because everybody else was already going with 8-pin connectors). Always annoys me when manufacturers decide to go against the general way the trend is going.

 

Like the faceless shadowy grey figure in the background, whispering in the ear of the engineer... 'don't you think we need a 10-pin connector there, we don't need to follow the rest of those manufacturers'.... Engineer decides it needs a 10-pin connector...

 

Shadowy figure slopes off rubbing their hands and grinning to themselves.... 'and they will have to purchase the replacement from us, because nobody else makes them..... Better still when they can't get the replacement anymore, they will have to buy a whole new computer'.... MUAAHAHAHAHAHAHAHAHAH!!!!!!!1

It'll only accept an identical replacement I believe. HP, Dell & Lenovo tend to have their own pin-out combinations for PSUs, they don't take kindly to 3rd party ones.

As luck would have it, I have three in stock. £35 + vat to you.
