Power Supply Concerns

[Volta13]

Good Morning, the problem is as follows:

I recently purchased, and received a Tritton Pro+ 5.1 True Surround gaming headset with mic (PC Version). Upon installation, I was slightly disappointed to realise that my headset did not work at all. After further investigation, I realised that I lacked the necessary audio jacks on the back of my PC, the audio being on-board, and that my particular model of headset does not come with the decoder box from Dolby/Tritton.

I therefore purchased a sound card, an Asus Xonar DSX PCI Express 7.1-Channel Audio Card. Everything looked to be okay, I am waiting for it to arrive.

However, I have realised after double checking that my PSU may not handle the extra power requirements of the card, my specs so far are as follows:

CPU: AMD Bulldozer FX 8320 Octo Core Black Edition (Not Overclocked)
GPU: NVIDIA EVGA GeForce GTX 780Ti Super-clocked Edition (w/o ACX Cooler)
M/B: Gigabyte 970a-DS3 (not sure what rev. level)
HDD: Seagate Barracuda 7200rpm 1TB
SSD Boot Drive: OCZ Vertex 128gb SSD
RAM: 16GB Corsair Vengeance 1333Mhz DDR3
CPU Cooling: Corsair Hydro Series H100i Liquid Cooler (two fans and a 240mm rad)
Optical Drive; Standard LG Drive
K/B: Razer Blackwidow Expert 2013 Mechanical Gaming Keyboard
MOU: Razer Abyssus Mirror Edition Gaming Mouse
PSU: 750W OCZ Vertex (Non Modular)

I also have a printer and some external speakers hooked up.

I read that my 780ti Required 600W Power as standard, and found a link which said during gameplay, I could reach up to 380W of power draw from my sound card.

The combined total of these cards is more than my PSU can handle, so bearing in mind that I have already ordered the card, what should I do? Even if it does work, will it decrease the product life of my other components, or do I risk frying my other components?

Any help would be very much appreciated!

Thanks

750W OCZ Vertex is Enough do not worry

Your sound card is very unlikely to draw much power. I feel safe saying that it isn't going to put your system over the edge. Your printer and speakers don't draw from your PSU because they are powered directly from the mains.

I did a quick calculation on yours system, taking some liberties on things I don't know for sure, but picked for worst case scenario. It came up to a maximum of 663W recommended 713W. There is no way that your sound card is going to draw even 20W, so you should be fine.

Now if you are already having unexplained lockups, restarts, BSOD's, etc, then you may be on the cusp of drawing too much from your supply already (which would mean something is wrong with it), so the sound card wouldn't do it any favors. However if you aren't experiencing anything like the above, you should be fine.

Thanks so much for this, I will go ahead and install it! That has put my mind at rest! No current lockups or PSU issues at the moment!
