PC Graphics

[pixelcomposer]

I'm trying to get my rig ready for the Next gen AMD cards coming out the beginning of next year.  I did a little googling and saw 700w as a requirement.  What im trying to figure out is if thats the amount my psu should be providing to the overall system including the graphics card or if that means i need an extra 700w more than the current system is providing?  Right now I'm sitting on a 750w psu so does this mean i need atleast 1450w?

If google "pcbuilder.net", you can build a system and it will give you an estimate of wattage. PSUs have an efficiency range and curve. It's a graph of how efficient the PSU delivers power at various voltages. Then ratings also give up an idea of this as well. It's best to simply google ratings and read up on it. You might have to add your GPU wattage manually or mentally.

Google "psu tier list" as well. The cultist one will given you an idea of psu quality. The PSU is one of the most important components in a PC, don't go cheap and try to get single rail.

It's not an easy question to answer. Take info from pc builder, then give yourself some head room for power demand spikes, then keep budget in mind.

700 Watts is just the total  amount of output wattage your PSU can provide to your PC.

Most of the time your PC will never need to use 700 watts unless you installed a very power hungry GPU card or hardware to your PC that will overpower your PSU output of 700 watts.

To future proof your PC I Suggest you install a 1000 watt or higher PSU metallic rated (Platinum, Gold, Silver, Bronze). With a 1000 watt or higher PSU it will easily handle any high powered GPU card and CPU installed unless you install 2 high powered GPU cards.

First you need to see what is the minimum PSU wattage you need for your GPU card and check your CPU minimum PSU wattage needed. Then purchase a PSU with at least 100 to 150 watts higher then the minimum PSU requirements.

The PSU is one of your most critical components in your PC. So make sure you purchase a high quality metallic rated PSU. I personally suggest at least 850 watts or higher. 1000 watts or higher PSU to future proof your PC for most future GPU cards and CPUs being sold in the Retail market

According to leak rumors by Videocardz.com, the next AMD released card will be the RX 9070XT and will have a 260W rating on the reference model.

This places it in the same ballpark as the current 7800XT which AMD recommends a 700W power supply. The power supply recommendation covers the entire system power, so depending on what other components are in the system (namely CPU) and whether you choose an overclocked GPU model or intend to do any CPU overclocking, your system may require slightly more or even less.

Your current 750W could very well be perfectly capable. I wouldn't suggest buying a new power supply based on card rumors.
