4870 Power Needs - Page 2

post #11 of 16
Hmm here's a paragraph that might be relevant?

Quote:
When we simulated a heavy load with the benchmark rig, though, we quickly encountered problems. The secondary rail was fine, only needing a 5A draw for the P4 socket. The primary rail had problems with overload, as it was loaded up with 11A to simulate a heavy load from the ATX socket, SATA, and Molex connectors, as well as a further 10A to simulate the two loaded PEG connectors. This adds up to an unwieldy 21A, which is 3A more than the supplies maximum load. Unsurprisingly, the supply shut down very swiftly when we started dishing out this punishment.
their conclusion about the problem:

Quote:
While the Akasa did manage to pass our tests, we came across a significant problem. Both PEG connectors are attached to the primary 12V rail. This means you may come up against it if you attempt to run a pair of high-powered graphics cards in SLI or CrossFire mode.

Further, one-half of the EPS connector (pins 5-8, CPU2) was also sharing the primary 12V rail, too.

Now they're talking about running two gpu's from early last year, but your rig may be putting added stress that theirs did not. I think you'll have to test and find out if it's the extra stuff you're running, so unplug a bunch of stuff and see how it goes.

Note that they think the 12v rails have 36 amps on them because of what the manufacturer states - why they do not subtract the 150w on the 3.3 and 5v rail from 500 and divide by 12 to get 29 amps (not good) is beyond me.

Either way, I think that's pushing it.
Not to offend but if that were true he'd either have 36a or 40a - he'd be totally set if so.

I'm suspecting that those numbers are lying what with the amount of watts supposedly being spread across them.

Right Just had a quick session, it shutdown once, but temps never went above 50c at 60%. Think it must be the psu. All these numbers go over my head when refering to power supplys. I do know you need a stable psu for overclocking though.

2 of my Hard Drives are just for storage and I could go on board sound if i gain performance. I also have 2 x 2gb ram, if that uses less power than 4 modules.

Will any of these help?

Just unplug everything you don't need (everything, soundcard, et al) and see if it shuts down or not during play.

If it doesn't you need a new power supply. If it does you still may need a new power supply, but it's less likely.

Managed to find this info, maybe some one could take a look and see if this is the likely culprit. Pretty sure its the PSU, just want to be 100% before splashing the cash.
