speaking, the biggest power draw in a modern PC will be in its graphics card, with TDPs of up to 300W, or even 450W with modern cards.<\/strong><\/p>\n<p>Compared to the ~80W of a standard CPU, the second most power-hungry component in the PC, that\u2019s quite a lot.<\/p>\n<p><strong>Fortunately, a wide variety of graphics cards exist- including those with much more reasonable TDPs and required wattages, like the Nvidia GTX 1650- which can operate off of 75 Watts of PCIe power alone<\/strong>.<\/p>\n<p>GPUs have also generally grown more power-efficient over time, though <strong>recent high-end releases from Nvidia and AMD are seemingly forgoing that in favor of slapping on more silicon and another power connector.<\/strong><\/p>\n<p>That\u2019s a valid option, I guess, but <strong>not great for users hoping to power their graphics card with a single 6-Pin or 8-Pin connector.<\/strong><\/p>\n<p>So, <strong>GPUs are the most power-hungry component in a modern PC-

generally consume that much power, but it\u2019s still wise to get a power supply with a good amount of headroom (a couple of hundred watts at least) over the total wattage of your PC.<\/strong><\/p>\n<p>When pushed to max capacity, PSUs tend to exhaust more heat and consume more power than they would otherwise.<\/p>\n<p>Having some headroom, especially with a high-efficiency power supply, is a great way to keep power consumption and noise down. Plus, maintaining system stability in case of overclocking.<\/p>\n<p>All that being said, let\u2019s get to the big question-<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Happens_If_Your_PSU_Is_Too_Weak_For_Your_GPU\"><\/span>What Happens If Your PSU Is Too Weak For Your GPU?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If your PSU is too weak for your GPU, a few different things might happen.<\/p>\n<p><strong>First and foremost, you may just find yourself unable to fully power on your PC with the GPU installed, or find that it only outputs a black screen when you use it.<\/strong><\/p>\n<p><strong>If you\u2019re able to boot into Windows without crashing, chances are your GPU is running under the lower end of its power limit...but once it\u2019s properly stressed and tries to reach for the wattage that isn\u2019t there, you\u2019re most likely to see a full system crash. <\/strong><\/p>\n<p>I once experienced crashes like this when my power supply was plugged into a UPS (Uninterruptible Power Supply) that didn\u2019t have enough wattage to match it.<\/p>\n<p><strong>Besides undervolting your graphics card to meet your system\u2019s wattage requirements, the best thing you can do in this situation is to either get rid of some of the other power-hogs in your system (like a lot of storage drives) or simply find and upgrade to a stronger, more efficient power supply.<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Most_Important_Things_To_Identify_in_a_Reliable_Power_Supply\"><\/span>Most Important Things To Identify in a Reliable Power Supply<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Wattage_Efficiency\"><\/span>Wattage &amp; Efficiency<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Wattage and efficiency are two of the most important things to identify in a power supply<\/strong>.<\/p>\n<p>Your Power Supply\u2019s wattage will effectively determine the maximum power of your graphics card upgrade, while its efficiency will determine how well it can do without excess power draw or heat.<\/p>\n<p><strong>Normally, your graphics card documentation will come with a recommended PSU wattage recommendation to pair with it.<\/strong><\/p>\n<p>While these usually aren\u2019t the strict <em>requirements<\/em> for the GPU to run, it\u2019s definitely smart to stick with these recommendations or better if you don\u2019t know the wattage of the rest of your PC build.<\/p>\n<p>This is an easy shorthand if you don\u2019t want to do research to find the right wattage for your PSU.<\/p>\n<p>With Efficiency, you\u2019ll want to look for ratings of 80+ Gold or better for a semblance of solid power efficiency.

class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes, unfortunately.<\/p>\n<p>Until recently, GPUs were somewhat restricted in their power requirements by only being able to demand one or two 8-pin PCIe power cables at a time.<\/p>\n<p>As of the release of the RTX 3090, that number has now been upped to 3 8Pin PCIe power cables at once, allowing for a maximum power draw of up to 450 Watts and near-definitively proving that there is no PSU God protecting them from this abuse.<\/p>\n<p>While modern GPU architectures have made leaps and bounds in performance-per-watt, the high-end graphics cards still have fairly high power demands.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Where_can_I_calculate_the_wattage_of_my_PC_build\"><\/span>Where can I calculate the wattage of my PC
