If you run cpu and gpu at stock I think you'd be ok, most I've seen the Tri-X 290 draw is about 230w. I don't know if 37a on the 12v rail is enough though, should be but not sure.
Oh yeah that's fine.

Thanks taem. thumb.gif

Well, i'm running my system (sig rig) 290X OCed + E3-1230V3 @ 3,7ghz (4770 w/o IGP) on a 450W Superflower GG 80+ Gold PSU. Everything works fine. No crashes etc.

Keep them under 100C

That's kinda high. For me 80c tops and I prefer 70c though 70c is extremely difficult to get without undervolting. This Tri-x at stock with a custom fan curve can do 70c vrm1 unless your ambient is really high or your case airflow is poor.

My VRM1 goes to 88C and VRM2 to 62C during 3h of Crysis 3. Stock volts, oc @ 1085/1350.

That's really high for this card, I'm surprised. I posted hwinfo screens earlier, my Tri-X hits 71c core and vrm1 in a Metro LL bench heat test, and that's as upper card in xfire. Game temps are in the mid to high 60s. But ambient during testing was 22-23c and I'm running the fans on an aggressive curve. How's your case fan setup? I do have a side fan which helps hugely in my experience.

Remember I have the S1 Plus mod.

For some reason, BF3 heats the GPU less. But during Crysis 3, GPU core maxed out at 84C, VRM1 88C and VRM2 66C.
But hey, just a note: The Accelero S1 Plus with the turbo module is rated to handle 120W TDP. R9 290X is 275W or 300W? Considering that, the S1 + 2x140mm fans do a very good job, also at a quiet noise level.

Pic of my custom VRM1 heatsink:

It's a cut up stock amd heatsink. I'm just surprised that the VRM1 is still running hot. The heatsink is quite high and the aluminium base is thick.. I've screwed it tight to place and shouldn't have too little pressure..
But oh well. VRM's are meant to work up to 125C, if not more. My brothers HD4870 2GB's VRM's ran at 130C and he didn't give a sht. biggrin.gif Still works.

It's almost criminal to replace this Tri-x cooler when it's such a good performer biggrin.gif. But quiet would be nice, this cooler is loud. With vrms, yeah the temp is within spec, but temp that high affects oc stability. But if you've got stable clocks dialed in I suppose it's not an issue. I like to run pointlessly low temps though lol. I'm leaving gpu power on the table because I oc less than I could just to keep temps below 70c when they'd be just fine 10c+ higher.

My system, with an OC'd 3570k, OC'd 290x, and 3hdd's and an SSD draws a max of 400W AC. I think you'll be ok with the 290 and that PSU.
