HD5830 power draw?

It will be fine, assuming that you're not running with several HDDs and intend to move on to CrossFire (assuming that card can even do CF).

The VX450W can do 33A on the single 12V rail IIRC, I've used plenty of them myself and they were good PSUs (it's a shame Corsair doesn't make them any more, at least in the UK).

This is a hero first post! I thought it'd be ok, but I wanted to check with the experts. Right now under full load I only do about 225W (system), so I figured bumping that up even 60w should be fine.

Thanks!
 
What does your system do when idle, just out of curiosity? My Athlon II X4 + 5770 system does about 80W (idle) and 150W under load.

Your 225W figure surprised me, but I guess you've got a beefier CPU and GPU than I have. I wonder if they were given identical loads whether the figures would be any closer.
 
At full load mining bitcoins my system draws about 350W from the wall. This is a 1090t, 5850 OC to 955MHz, 2 hard drives, 1 SSD. While the 5830 does draw slightly more power than a base 5850, it's probably less than my OCed card. 450W should be more than enough, assuming it's not some cheap brand that exaggerates it's rated capability.

You'll be alright; although it probably wouldn't be worth it to overclock and overclocking far enough can push the PSU too much.

Even a slight OC should give me a huge performance increase on my mining output, so I'm going to do it.

Idle my system draws 112W. With CPU idle, GPU maxed 158W.
 
Those corsair psu's are great. My hx 520 has been running an i7 920 @3.6-4.2 for about 18 mos, and before that it ran an x3350 for a year or two, before that a q6600, etc etc etc, all running DC 24/7. For the past couple of years have also run the video card with it, mostly a gtx 260 but lately a gtx 460. Corsair is notorious for under-rating their psu's, most manufacturers would rate that one at 550+, and even many quality companies would rate it at 500w.
 
that is a very good quality power supply and is decent for your needs if you are not aggressively overclocking. you can mildly oc the 5830 without issue so go for that if you need to. now if you also have the X6 oced by quite a bit then yes you would run into trouble.

The 1055t is OCed right now, but I'm actually probably going to underclock it when I put in the 5830. Stock is 2800, I'll probably dip down to ~2600 (right now it is at 3250). I probably don't need to underclock it because it sits idle the vast majority of the time, but I think it might help with the power situation and also heat.
 
You can underclock if you're worried about heat, but you could overclock both cpu and gpu as much as you want with that psu. Corsair rates their psu's at 50c, not at 20 or 30c like most manufacturers do.

bad advice because no he could not go all crazy with the overclocking. an X6 alone could use well over an additional 100 watts when overclocking really high. that right there would be putting the psu pretty close to its 12v limit even without overclocking the 5830.
