Can my PSU handle my computer at a lower load?

[elitej13]

The specs of my build are:
CPU - AMD FX 9370, 4.4GHz
MoBo - MSI 990FXA Gaming
GPU - Asus Radeon R9 Fury Strix
(Manuf. website claims "up to 375w")
PSU - EVGA 500w 80 Plus Bronze
("Supporting 40A on a single +12V rail")
1xHDD
1xSSD
And not including the PSU's there are 3x120mm fans

Using http://outervision.com/power-supply-calculator I found :

Load Wattage: 561 W
Recommended UPS rating: 1100 VA
Recommended PSU Wattage: 611 W

And that's so close to the PSU I have, it's very tempting. But I have no idea the associated risk.

I just upgraded the GPU, CPU, and motherboard as one of them previously went out. But I didn't realize that the new specs might be too much for my PSU. I am okay with purchasing a new one, but I don't quite have the money to do so right away. So I'm wondering if my current PSU should be able to handle the load of starting up and doing setup stuff.

Also any recommendations for upgrading my PSU?

If your power supply overheats or overloads, you will be buying a new one, and possibly buying a new motherboard or CPU as well....

If you absolutely have to run with it, underclock your CPU to 3.2GHz and drop the Vcore to 1.3V. That should reduce the load on your PSU.

How risky is it to start the computer up? If only to get into bios.

 

[lodders]

BIOS should be no problem because your GPU won't be doing any 3D processing

Ok, thank you! Any suggestions for a new PSU?

Warning: This power draw of this CPU is almost twice that of the average CPU. Due to this, AMD recommends using at minimum a 850W to 1000W power supply. For cooling, AMD recommends using either either closed loop liquid cooling , h100i minimum or full system liquid cooling.

Do not power that monstrosity of a cpu and a 600 dollar gpu with a cheap lackluster 30 dollar power supply, its a bad idea on so many levels. Don't undervolt anything just dont do it at all, get a new psu.

^^^ x1000!!!!

DO NOT RUN THAT!

Haha ok, it sounds like I shouldn't turn on the computer. Thank you for the recommendations! I knew about the select few motherboards for the CPU but I didn't know cooling was that big of a deal. What are some good relatively cheap closed loop liquid coolers? Or should I not risk underdoing it with the cooling system and just go all out?

The 9000 series processors need solid cooling (along with the power as we mentioned), do not cheap out you will be sorry. Get yourself a nice dual radiator liquid cooler and make sure your case is well fed and exhausted with good fans. Its not worth the risk with that processor, all youre going to do is fight with it otherwise.
