no spare PSU to try

that PSU cost me £50+ I would have thought that was good.

50 quid for a psu with 16a on the 12v rails is a total rip.

it is. his psu has 34 amps though.....

You can't add them up linearly

That would be silly without knowing the specifics as the current is likely to be shared between rails on demand ( i don't know but speculating as thats what many PSUs do)

no but you can assue the pci-e conenctors are on a seperate rail to that which supplies the montherboard with 12v.

a lot of recent psu's have one big rail btw. such as my corsair 620w

correct my PSU has 2 x 12v lines. One with daul PCI-e and one for the other stuff.

My new corsair has even less vlots wise but it does have 3 lines totally 40A and that's from the offical manual and box.

Yes ofcourse, but my point was about linearly adding them up to 34A which may not be true at all. 34X12 = 396W on 12V alone leaving about 100W on the other.Sounds right for the cheaper PSUs.

Infact since you have the corsair you should know that the 50A on the 12V is not a linear sum of all the 3 12V rails because it is one big rail as you put it.

The easiest way to calculate is to divide the max combined wattage on the 12V rails by 12 to get a single rail equivalent.

I've seen noticed while playing STALKER that this GFX card gets to 69C before it goes bang.

Also I contacted the guy from eBay and he said I've had many happy customers so I contacted a few of them and they said "Yeah we've had duff card too" all reported overheating and lockups

So it would appear that the eBayer know that these cards where duff and was trying to pass them off as working hoping no one would complain. One of the previous customers made the same mistake and purchased a new high branded PSU before deciding his GFXcard was dead.

Hell maybe I've even got his dead card because he returned it to him.

my point isnt that it can reliably output 34amps at 12v. i never said that. my point is that it has two rails. whatever way you want to crumble that cookie its still more than 16amps isnt it? in which case, its still more than enough for an x1950. remember, an 8800gtx only uses 13amps or so at load

bertybassett · 4 Jul 2007 at 17:38

the short story is my current PSU is OKish but not super great.

The corsair 520W is ok too but is it much of any upgrade over the North-Q

Both PSU are just ok and should have run that GFX car without any faults.

OK next question do you think my north-Q PSU would run a 8800GTS? because if I'm buying a new GFX card then I'm getting a good one.

Well scroll up to the top where you said it has 34A. Infact as I've been trying to you explain already, that figure may not be right. Nothing at all to do with whether that psu is fine for his setup.

obviously in this case it should be plenty for his setup.

IT says 34amp. stop being a pendant when you know what im talking about, or have you no idea how much i know about power supplies?

have you tried it with the fan running at 100%? if you have then i'd say your case is too hot tbh.

these cards need to be kept below 65c, is the heatsink clean? you could try reseating it and add some better thermal paste.

Columbo · 4 Jul 2007 at 18:39

Im running an X1950xt, with 6 HDD's and two DVDRW drives on a thermaltake 480w PSU. His should be fine.

bertybassett · 4 Jul 2007 at 19:00

When I get my refund ok I'm getting a new 320Mb 8800 GFX overclockers value one unless the ATI HD2900 is better but I don't believe it is.

ahem where does it say 34Amps? I've skimmed through the review and didn't find it there.

edit/ I don't know how much you know but i hope you know enough not to just add 16+18 to give 34 which what I've think you've done.

bertybassett · 4 Jul 2007 at 19:02

@spookywillow thanx for the help but if the card does not run at stock cooling no overclocking then it is not fit for the job it was made for, so I returned it for a refund.

spookywillow · 4 Jul 2007 at 19:11

ok np

at least it'll all be sorted out soon

bertybassett · 5 Jul 2007 at 00:25

I so hope so.

C64 · 5 Jul 2007 at 03:58

No way just got a sapphire x1950 pro am having major issues
with it i am not sure the 520hx is up to the job
this card needs 30a? well even though the corsair is 40a thats split up so
i am thinking this needs a 620 hx minimum getting black screens followed
by random restarts only thing thats new in pc is the card so it must be that.

bertybassett · 5 Jul 2007 at 09:22

its over heating that your problem.
