The inevitable "I need to buy a new PSU" thread

Well as mentioned elsewhere, I think my new card is crucifying my existing stock 450W power supply that came with my HP Workstation.

Not bothered about noise, quality etc... as long as it's powerful enough to run the card, and it's as cheap as possible then I'm happy, as buying something expensive for my reasonably old system would just be daft, allthough I suppose I could always move it into a new system if I were to build one in the future.

I'd say most named 500w+ PSUs would probably be okay. I use a Taigan and while it's only 450w (I think) it runs all the crap in my machine fine.

Does the card have two power connectors, and are you running them off one connection to the PSU with a splitter?

Just a thought.

Otherwise try disconnecting any USB devices, just to see if it will tip the balance and confirm it's a power issue, rather than a temperature one.

Edit: A decent PSUs always a good investment, regardless, as it can outlast pretty much every other component in your PC.

WRONG!

We've been over this a hundred times.

PSU quality is directly related to how "powerful" it is.

For example you could buy an ebuyer special 700w psu and put it in your machine. it probably wouldn't last a week (and it could kill your computer along with it)

Then again, you could go out and buy a nice mid/high end 400w PSU that could happily handle your machine.

Also: be careful, HP might use weirdy non-standard connectors, I don't know.

Either way, I've had good experiences with tagan and enermax PSUs, neither are too expensive and (depending which you buy) will service you happily, and most likely your next machine.

I've got a couple of Tagans and im very pleased with them. Quiet, efficient and have a 3 year guarantee on them

they am win!

Good point. We've got a problem at work whereby they bought a load of shite quality workstations and the PSUs have started going pop because they're cheap and underpowered. They're a weird size (probably why they were cheap) and so we can't get any replacements because the company is now bust and we can't find the freakish things anywhere else.

what berk said. a quality PSU is something you do not skimp on.

After a bit of research, it looks like changing my PSU is nigh on impossible in my xw6000 due to the non standard PSU's HP decided to fit into the xw workstation range.

If I were to earth a seperate power supply to the casing, and run a cable into it feeding the graphics card, would that work? (in theory)

I know it's a very dirty solution, but I have a spare power supply that's doing nothing, and wondered if this was possible?

yes, that'll work.

You could try to find the HP pinout, and then just gank the existing connector and mod it onto the new PSU.

May not be possible.

Thanks, should I earth the PSU to something though, or are PSU's not earthed because they are fitted to the metal case of the machine?
Basically it would just sit ontop the PC under my desk, so not worried what it looks like narf.

Also suggestions for a good voltage monitor that works with my Intel Based HP XW6000 motherboard would be ace

Post by **fabyak** » February 28th, 2007, 8:24

as I understand it, you earth the PSU by screwing it into the case, but it can't hurt to have the earthing bit hooked onto it as well

[edit] It should be able to monitor stuff like that in the BIOS and if your motherboard can do it it may be able to autoshutdown if it goes a bit bonkers

Post by **Dr. kitteny berk** » February 28th, 2007, 8:39

You're close, but wrong.

The case and components are earthed to the PSU which earths using the magical 3rd pin on the IEC power connector.

I stand corrected

I have ordered for my new build a Hiper 580w modular type R, dont know how it will go but im hoping it will be nice (no more web of unused wires in my pc!!!) Also seems to be at a fair price too.

*edit: excellent grammar me*
