Single 580 on corsair 550vx

post #1 of 11
Thread Starter 
I know recommended is 600w. I am curious to see how much my 580 would be bottlenecked by my e8400 in my HTPC rig that runs off of a 550vx. I will overclock the e8400 to 3.4ghz but leave the 580 stock.

I personally wouldn't try it. If the psu does end up being able able to run it, then it definitely isn't a long term solution.

I'd go for a good 650w to be safe but since you just testing it, go a head and see what happens I guess.

I'm just testing it and mostly just don't want to tear apart my sig rig and transport the 850w lol

The recommend of 600w is with a standard system. Meaning a not oc system.

But a 550vx is 80+% and my current rig (2600k + 580) pulls just under 400w from the wall under complete artificial load (furmark+prime95). Let's add 150w to that so 550w. Corsair is known for being conservative with their power supplies so I'm sure it can do 600w at least.
I don't see why I can't run the 580 off of a 550vx just for a little bit of benching/testing?

Huh @ responses here?

A vx550 Watt is more than enough to run any single GPU there is on a moderate overclock. Go nuts.

You could run your main system off that PSU...
Try it out, it'll be OK.

It'll be absolutely fine. You'll have plenty of breathing space also. People so often overestimate power requirements, I think they've been tricked by the marketing...

I ran my system as it is but with an overclocked GTX480 for a while, and no problems; was pulling around 400W from the wall under prime 95 AND afterburner (so unrealistic loads again).

It'll be fine paired with an e8400, I ran a overclocked a e8400/480 on an ultra 600w X3 fine.
I'd have doubts on an oc'd quad system.

Planning on getting another 580 possibly. Plus a real benefit to the 850 is the fan rarely ever even starts up and my rig is made for extreme silence.
