I played crysis for a bit, like 10 mins, and got awesome framerates. The power supply was hot, i could feel it. Then it started making a SCRATCHY sound as if something had falled loose in it. I turned off the Pc as fast i could.

After the repeated warnings on this thread you still went ahead with a potentially inadequate power supply?

Well as long as you didnt lose any parts.

Edit: Its amazing how we can critizice someone for taking a calculated risk, and yet turn our backs to do similar things. Anyone here not overclocking?

Quick question: those adapters have two Molex connectors, right? You didn't plug them both into the same chain, did you? It probably would have been fine if you split the load across two chains, like it was intended to do.
Of course, if both chains are on the same rail, that's no good anyway.

Edit: A careful re-read shows that the OP specifies single-molex to PCI-e.

Bad comparison. I keep my chip as close to stock as possible (3.5 @ 1.39)

This thread is like saying "Should I push my chip to 1.65v?" and everyone saying "no, that's too high"

And then doing it anyway and being like "Whoa almost fried my chip!"

I think that the OP was just looking for reassurance, and was going to use the PSU regardless of any warnings.

There's risks and then there's plain foolhardiness.

17A? Too low.

And for those with VX550s commenting, this is a 50A power supply. That's more than 800W Thermaltakes and whatnot.

update!!

i got a new power supply, the M520 Real power. From coolermaster. It has triple 19A rails. Pretty awesome.

This one might be better. It has 34A on the +12V rail (408W). I don't know for 100% sure if it has enough power for a single 4890, but it's certainly a much better unit than the SunPro, and therefore it has a much better chance of easily providing that power.
