Hi

I am just upgrading a friends machine, which is a HP Pavilion 760n.
It was tough enough to find out which type of standard PSU the thing comes with, much less how many watts the thing provides (hp specs page is not that specific).

Now I want to put a Allied PSU AL-A400ATX 400 watts PSU in that thing.
Does anybody know if HP is using non ATX standard dimension PSUs in their Pavilion machines?

If yes, has anybody experience in fitting it? Is it possible at all?
If not, is there a source to get HP powersupplies cheap, without rewarding HP for their "I-can't-believe-they- still-pull-this-BS" proprietary "it-must-never-be-standard" scheme?

Any pointers are appreciated.

I think most pavilions use a microATX, but it probably varies if you tower was full size or not.

Hmm, I don't think the tower is full size. It has two slots for CD-ROMs total, a floppy and that is it...
No more room for any CD-ROM / DVD - Burner size devices.
I think a full tower would have at least 4 of them if I am not mistaken.

I think it might be a midi tower, from my experience, since a mini tower will be really really tiny and this one is not.

Now Is MicroATX a standard with it's own PSU dimensions that differs from normal ATX?
Is there anywhere on the web were these standards are defined in a similar way of RFCs?

Well, I measured it:

It is 3.5 inch high, 3.75 inch deep, and 6 inch wide
and definitely not standard and of no standard that I have ever heard of...(mini ATX is different)
Silly them, as I thought, up to their proprietary tricks. The easiest thing is probably to replace the whole case with a white box and go standard with the PSU.

WHY oh WHY do companies don't get this? We are sick and tired of these custom made gadgets, be it connectors, cases or whatever and them being custom for no apparent reason or benefit to the customer.
And in the end, being only for the good of the company by forcing the customer to buy a "hum-drum nothing-special" part at the rip-off prices they can dictate.

In case some representative of HP reads this: You company has just taken damage in my eye. Please stop using this policies. You can maybe fool clueless users, but the pros among us will just frown at it.
For me anther good reason to not buy HP desktops, besides them being overpriced.

Is it so difficult to follow industry standards?

*shaking head*

Could it be a BTX size? A guy at work just clued me in out the BTX standard that hasn't really taken off but is out there. Unfortunetly, I can't tell you what the BTX standard is. Possibly check newegg for a BTX power supply and see if its dimensions are correct.
