Hi, I have got hold a a pc pretty cheap but thte PSU on it is bust so I need to get new one. The problem is the connectors on it are not the standard ones Im used to seeing!!! The motherboard is a HP saturn2 revA and the current PSU ha Hp part number 503378-001. The PSU has a few cables coming off of it;

1 6 pin P1 cable
1 4 pin P3 cable
1 6 pin P2 cable (one row of pins)

Can someone point me in the direction of a suitable PSU 500w of abov. Dont want to spend my hard earned cash on one that isnt suitable as I can not find referrence to the P2 cable in any descriptions. Thanks and any help is much appreciated.

Can you find or post a picture of the connectors and the PSU? It seems to be a non-standard unit, and may not be the standard form factor that most units are. Best to check first and not buy something doesnt fit.

Heres a picture of the connectors. I tried to get a decent pic of the psu but the res on my 5mb camera phjone is so low you can make out the writing..! The 3 connectors are the only ones that come off the psu. The motherboard provides power for all the hdd and dvd drive through a 4 pic connector on the board.

That 6 pin one almost looks like a PCI-E connector, does it have 3 black wires running to the top pins and 3 yellow wires running to the bottom set of pins?

Im not sure what the P2 one is, the P1 one looks like a 4 pin ATX auxiliary CPU power cable, if it has two yellows up top and 2 blacks on the bottom it is.

Check here and see if you can find something that looks like the P2 connector.

The picture of the PSU is more to make out its general shape and determine its form factor rather than to make out writing so it doesnt matter if its blury.

Ok cool. I'v uploaded a picture of each connector with its designated conection on the mobo, one of the psu sticker and one of the psu / mobo. I thought the thin 6 pin connector might be an aux connector but they seem to be used on really old boards. The board itself uses PC3 10600 memory so its pretty new and the cpu is a Q9500 775 slot so the build is pretty new. Nothing to skream about but a decent build. Below are the pics,

I'm quite tempted to just buy a new mobo and psu if the PSU needed is awkward. Do you recon the parts are worth the expense? I'm currently running a AMD 64 2x 6500+ and some crappy memory..

Your system is so proprietary as to be useless once any part of it dies. Please post a budget; a decent machine can be built for less than $500.

thats absolute bs on hp's part. I hope I can salvage some of the parts and not have to spend loads to upgrade. It currently got 4 x 2gb 10600 memory, a q9500, hdd and the fan I could use. I cant seem to find a cheapish mobo which will accommodate the memory and a 775 socket cpu. Any recommendations on one and a psu, or is it even worth the expense? Woiuld it be better to ebay the parts and start fresh..

A Q9500 is no slouch. Still, spending money on S775 is rather a dead end. It may be worth looking into a new build. What is your total budget, do you play games, and what video card do you have, or want to get?

I havent got a budget as such.. was hoping to just use the parts to upgrade / salvage parts from my old computer. I'm currently running a amd 64 2x6500+, 6 gb memory which is pretty slow to todays standard, and a geforce 9800 gt graphics card. The motherboard is a standard biostar but is am3 compatible. Dont really play games on pc as got both xbox and ps3 and prefer them due to sheer simplicity and cost.

Yer a 775 would be but I was hoping to be able to pick one up for around £30 and maybe a similar priced psu. Looking at motherboards which supports the cpu and memory costs around 150 which is ridiculous when the 775 isn't supported any more.

Hmmm, I know essentially nothing about UK merchants. There's ebuyer, and another name or two I might recognize if I saw them...
