you discover that it\u2019s too outdated for your needs, you probably need a new one.<\/strong><\/p>\n<p>If you aren\u2019t sure how to pick out a new PSU, here are a few quick, core tips from me:<\/p>\n<ul>\n<li><strong>Always stick with the same or a smaller form factor compared to the original PSU<\/strong>, as long as you can get the <strong>PSU mounted stably in your chassis.<\/strong><\/li>\n<li><strong>Going 200-300 Watts in capacity over your maximum estimated wattage will help your PSU run more efficiently<\/strong>.<\/li>\n<li><strong>Stick with 80+ Bronze efficiency PSUs as a minimum requirement<\/strong> (<strong>Gold or better recommended<\/strong>).<br>\n<noscript><img decoding=\"async\" class=\"alignnone size-full wp-image-19850\"
