430w psu ok with a Radeon HD7850 and AMD A10 5800k?

post #1 of 10
Thread Starter 
I think the title says it all. My full specs are as follows

A10 5800k CPU
Radeon HD7850 1GB GPU
Thermaltake TR2 430w PSU
Western Digital 1TB HDD
BIOSTAR Hi-Fi A85W FM2 AMD A85X
(Hudson D4) SATA 6Gb/s USB 3.0 HDMI
ATX AMD Motherboard
Ballistix 8gb DDR3 RAM

So should I get a new PSU or is mine ok? I will be running on a 23'' monitor at 1080p also.

I think you should be more than ok. a 7850 isn't going to use an incredible amount of power, even under full load.

Yep, that's quite alright! That CPU is 100W, the 7850 is 130W, everything else might be 50W to 100W. You'll be well within the 430W (especially a quality one like that).

Really? I've been reading around and got mixed answers so that's why I ask. I'm kind of skeptical still but I'll trust you guys.

Anyways what's the worst that could happen if that PSU can't power everything? Will it explode? (jk) Just worried I'll break my shiny new parts is all lol

Yeah, unless you were planning on some real heavy overclocking I suppose (The CPU might use 200W at 5GHz for example). And the 7850 is a very power frugal card. Even if you overclocked it as well, the voltage is locked so you won't raise the TDP of the graphics much.

When you overload the PSU, weird stuff happens (unexplained crashes and such), but nothing particularly explodes.

This! You have plenty of power.

If you based it off of its label wattage, you should have plenty of power. Quality-wise, you got a poor passive PFC unit build by HEC, that is probably only good for 300w at best. So I would go ahead and say get a new PSU regardless.

Not only no but hell NO the Thermaltake TR2 is god awful and horrible get rid of the damm thing before it kills your PC

And it cant even do 430 watts

^^ Agreed

430 watts should be plenty for your system, but you'll want a better PSU. Never skimp on the power supply.

whoops, my bad - didn't realize that was a poor choice. From a quality PSU then, 430W is enough tongue.gif
