How? Go ahead swap your supply from 500w to 350w and watch your rig's performances in 3d games.

Lmao, and if i put in a 600w ill be really screaming!!


:roll:

Not really, but at least you have some more headroom, in the event the load requires more juice on demand.
No you are the one who should take it yourself, dude.

LMAO, that isnt how it works. If there isnt enough power, it will freeze, severely slow down, or crash entirely. Every part consumes a maximum amount. If your PSUs max load on each rail is higher than that, you have a perfectly stable system. Increasing your PSU will do NOTHING but cost you money.

I don't get what youre not getting here.

You're contradicting yourself.
That's why you always need a beefy psu in order to prevent freezes, slow down, or crashes before they actually happen.

No, im not, you said "you can never have too much" and I said "yes, you can waste money".

Adding a stronger PSU to a properly configured system does NOTHING.

Do you honestly believe that if i went and bought a $300 1KW PSU that it would do ANYTHING for my system? Because if you do, go ahead and buy one and send it to me, and ill do a comprehensive test in this thread. If i gain ANYTHING, ill paypal you double what you paid.

One rail feeds everything else, and the other rail is supposed to be dedicated to the video card. Id find it very hard to believe that the card ALONE will draw 18A on the 12V rail (216w? lmao)

I understand very well how they work, Acanthus... And try around 300w on an X1900XT or XTX. There's a reason they suggest >30amps on a single rail.

You know that a single rail PSU will also have everything else drawing from it too right? In either case youre going to get similar power draw.

And i do agree, dual rail PSUs are all around retarded and pointless. Im just saying in this case it most certainly is not the issue.

300w on an XTX? That would mean crossfire would be damn near impossible to power.

You guys tend to overestimate power needs around here...

Dual core + CF + raid can't be done on a 650w?

I havent built any CF system yet (for obvious reasons) but ive run many a 6800GT and 7800GT SLI on 550w - 600w antec/enermax/fortron.

Max load for the entire system from the wall is ~28A assuming all devices are 12V, which they are not, however they are the majority of the devices in the system. This is why ATI recommends a 30A power supply. I can guarantee you if his Dell power supply has 18A on both 12V rails, he is well above what he needs.

PowerColor X1900 XT - 315w
Sapphire X1900 XT - 316w
Sapphire X1900 XTX - 336w
GeCube X1900 XTX - 337w
HIS X1900 XTX - 330w

Thats the ENTIRE SYSTEM not the graphics card alone...

Right...I'm agreeing with your side of the arguement. What part of "Max load for the entire system from the wall is ~28A" did you miss?

135w per X1900XTX = 11.25A on 12VB rail. 18A is plenty.

Now if he was trying to run Crossfire, that would be a different story.

the dedicated rail is for the CPU, not the video card.

the cpu get its own rail and everything else feeds off 12v2. there are a couple exceptions. i believe enermax has one where the cpu and the mobo are on 12v1 and everything else (peripherals and vga) are on 12v2. but thats an exception.

That sounds right.

I thought you were trying to argue that one card consumed 300w. I thought you had gone insane

12VA Should feed the CPU and system. 12VB is dedicated to PCIe (maybe system, but each HD and optical drive is ~1.5A maximum). Even if Dell decided to wire the system to 12VB that's still only 11.25A+4.5A = 15.75A.

Edit: The TDP of an 820 P4 is less than an X1900XTX. No matter how the rails are configured, he still has plenty of power. You're wrong rise4310. Sorry to cloud the issue with facts. If somehow the entire computer is wired to a single rail, he would not be posting from his computer right now, but instead would be calling 911 to get the fire department out there ASAP.

per atx standards, no, the cpu get its own rail

1.2.4. Separate current limit for 12V2 on the 2x2 connector:
The 12V rail on the 2 x 2 power connector should be a separate current limited output to meet
the requirements of UL and EN 60950

Ok, we're both wrong on certain points. However, the overall conclusion still stands that 18A is plenty of power on 12VB.

 

[rise]

yeah, i was just stating that for people who read this with lesser power supplies.

there used to be a big thing about not being able to oc on dual rail because the graphic card sucked all the power from the cpu

 

[Golgatha]

Just to make absolutely sure then, the OP should use a dual 4pin molex to PCIe adapter to ensure the graphics card is on 12VA and seperate from the CPU load bearing connector 12VB.

Here, this will make things more complicated. The 8pin connector on Intel 975X boards are wired to load bear on both 12V rails (12V1 and 12V2). However, my Enermax Liberty is wired to power the 8pin CPU connector with only the second rail (12V2). Both PCIe connectors run off the first rail (12V1). I suppose this eliminates the possibility that one could accidentally run the CPU and PCIe off of the same rail. Those guys at Enermax are thinkers. Still, 22A would be cutting it very close for ATI Crossfire even on my 620w power supply under the worst of the worst conditions.

UMMMMMM CHANCES AREE

TURN off the DX8 shaders cuz being Dell n00b u prob have it on..

ALSO turn off that low resolution texture thing right above it..

Make sure u set ur core affinity.

The PSU in the OP's Dell 9150 has an 8pin PCIe connection, and this system was built for an optional upgrade to a 7800 GTX. He's fine.

This thread has got WAY out of hand. He has a defective video card. Period. End of discussion.

Some of you have opened up your mouths when you know nothing of which you speak. I have the exact same PSU in my Dell 9100. On top of that, I have sold well over 450 Dell systems in the past year, and work almost every day with high-end Dell desktops. It's so frustrating to hear things such as, "his cpu is too slow," "his ram is generic crap," and of course, "his Dell PSU is junk."

And here the OP has a $70 PSU being delivered because he got bad advice, while his current PSU is in fact more powerful than the one he ordered.

Some of you have no business in this thread, while others have been quite helpful.

Yeah, this sort of turned into a power supply knowledge pissing contest. Bottom line is I too believe the graphics card is faulty and needs RMA. I'm sure the Dell power supply has a 6pin PCIe adapter, which is on a 12V rail separate from the CPU. His system worked fine until the upgrade and the temperatures he is getting from is card are WAY above normal. No amount of case ventilation has helped this, including leaving the case wide open. Downtime sucks when you have games to play, but that video card needs RMA.

 

[thecoolnessrune]

You could try this for a PSU replacement. That most definitely would rule out the PSU being an issue.

Your current power supply is more powerful than the one your purchased.
