The computer dies suddenly in the middle of a game? There&#8217;s a burnt smell from the case or a sharp whine from the back? These are classic signs of a <strong>failed power supply<\/strong> \u2014 the unit responsible for stable voltages to all the other hardware.<\/p>\n<p>A power supply is also the most dangerous part to poke at home: even after unplugging, its capacitors hold high voltage. Don&#8217;t open it. At the Comp-Master lab in Ashdod we test power supplies under load, replace them, and make sure the failure didn&#8217;t take other components with it.<\/p>\n<p>To be explicit: <strong>desktop power supplies we replace, not repair<\/strong>. A new reliable unit costs less than a safe repair of a burnt one, and a repaired unit always carries the risk of sending incorrect voltage to the motherboard and drives. In PlayStation and Xbox consoles, where the supply is internal and model-specific, it&#8217;s different \u2014 there we both repair and replace.<\/p>\n<h2>Signs of a failing power supply<\/h2>\n<ul>\n<li><strong>No power at all<\/strong> \u2014 no LEDs, no fans.<\/li>\n<li><strong>Powers on and shuts down immediately<\/strong>, sometimes in a loop.<\/li>\n<li><strong>Sudden shutdowns under load<\/strong> \u2014 gaming, rendering or video editing.<\/li>\n<li><strong>A burnt smell<\/strong> or a popping sound from the PSU area.<\/li>\n<li><strong>A whine or squeal<\/strong> that grows with load.<\/li>\n<li><strong>The PSU fan doesn&#8217;t spin<\/strong> or makes a metallic noise.<\/li>\n<li>The machine became unstable <strong>after a graphics card upgrade<\/strong> \u2014 the supply simply can&#8217;t deliver the power needed.<\/li>\n<\/ul>\n<h2>What we do in the lab<\/h2>\n<ol>\n<li><strong>Load testing<\/strong> \u2014 not just &#8220;powers on or not&#8221;, but measuring voltage stability under real load.<\/li>\n<li><strong>Separating causes<\/strong> \u2014 confirming it&#8217;s the supply and not the motherboard, power button or CPU.<\/li>\n<li><strong>Cleaning and fan service<\/strong> when the unit is healthy but noisy and hot.<\/li>\n<li><strong>Replacement<\/strong> with the right wattage, calculated from your CPU and graphics card.<\/li>\n<li><strong>Checking for secondary damage<\/strong> \u2014 a burnt supply sometimes takes the board or drives with it, and we check before returning the machine.<\/li>\n<\/ol>\n<h2 id=\"tablepress-65-name\" class=\"tablepress-table-name tablepress-table-name-id-65\">Comp-Master computer lab services price list<\/h2>\n<span id=\"tablepress-65-description\" class=\"tablepress-table-description tablepress-table-description-id-65\">Does not include the cost of parts, unless otherwise noted.<br \/>\nTo search for a service, it is recommended to use the search above a table<\/span>\n\n<table id=\"tablepress-65\" class=\"tablepress tablepress-id-65\" aria-labelledby=\"tablepress-65-name\" aria-describedby=\"tablepress-65-description\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">ID<\/th><th class=\"column-2\">Categories<\/th><th class=\"column-3\">Service Type<\/th><th class=\"column-4\">Service<\/th><th class=\"column-5\">Price<\/th><th class=\"column-6\">Warranty<\/th><th class=\"column-7\">Partial list of devices<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\">31143<\/td><td class=\"column-2\">Desktops<\/td><td class=\"column-3\">Power supply repair<\/td><td class=\"column-4\">Estimation of repair cost or inspection.

A cheap uncertified unit delivers less than it claims, and under load it&#8217;s the one causing crashes \u2014 sometimes taking the motherboard with it. We&#8217;ll recommend a unit based on your hardware: CPU, graphics card, number of drives and headroom for future upgrades. If you&#8217;re considering a new graphics card, check the power supply at the same time \u2014 it&#8217;s the most common upgrade mistake.<\/p>\n<h2>Bring it to us in Ashdod<\/h2>\n<p>A desktop tower is awkward to ship, so it&#8217;s simplest to bring the case to the lab at <strong>Gia Oni 6, Ashdod<\/strong> \u2014 no monitor or peripherals. If you&#8217;re in Ashdod, Ashkelon, Yavne, Gedera or Kiryat Malakhi it&#8217;s a short drive, and in many cases the computer goes back the same day. If the machine is in an office and can&#8217;t be moved, call us and we&#8217;ll find a solution.<\/p>\n<h2>FAQ<\/h2>\n<p><strong>Can a power supply be repaired, or only replaced?<\/strong><br \/>\nWe replace. A new reliable unit costs less than a safe repair, and a faulty unit endangers the rest of the hardware. If the issue is only a fan or dust, we&#8217;ll service it without replacing.<\/p>\n<p><strong>The PC won&#8217;t start \u2014 how do I know it&#8217;s the PSU?<\/strong><br \/>\nAt home it&#8217;s hard to tell: the motherboard, CPU or power button produce identical symptoms. Load testing in the lab separates the causes quickly.<\/p>\n<p><strong>Can a power supply burn other components?<\/strong><br \/>\nYes. A poor-quality unit that fails can send incorrect voltage to the board and drives. That&#8217;s why after a PSU failure we always check the rest of the system.<\/p>\n<p><strong>Is there a link between a weak PSU and crashes in games?<\/strong><br \/>\nA direct one. Under graphics load consumption spikes, and a supply that can&#8217;t keep up triggers protection and shuts the machine down. It looks exactly like a graphics card fault.<\/p>\n<p><strong>What&#8217;s the warranty?<\/strong><br \/>\n6 months on a power supply supplied by us. Parts brought by the customer are not covered on our side.<\/p>\n<h2>Related services<\/h2>\n<ul>\n<li><a href=\"https:\/\/comp-master.co.il\/en\/computer-lab\/experts-in-desktop-pc-repairs-in-ashdod\/\">Desktop PC repair<\/a><\/li>\n<li><a href=\"https:\/\/comp-master.co.il\/en\/computer-lab\/\">Computer lab in Ashdod<\/a><\/li>\n<li><a href=\"https:\/\/comp-master.co.il\/en\/comp-master-computer-lab-services-price-list\/\">Lab price list<\/a><\/li>\n<\/ul>\n<p>[\/vc_column_text]<div class=\"porto-block\" data-id=\"8655\">\n<p class=\"has-text-align-center wp-block-paragraph\"><strong> For more details, call now at <a href=\"tel:0732241747\" target=\"_blank\" rel=\"noopener\">073-2241747<\/a> or come for an inspection at <a href=\"https:\/\/www.waze.com\/en\/live-map\/directions\/%D7%A7%D7%95%D7%9E%D7%A4-%D7%9E%D7%90%D7%A1%D7%98%D7%A8-%D7%92%D7%99%D7%90-%D7%90%D7%95%D7%A0%D7%99-6-%D7%90%D7%A9%D7%93%D7%95%D7%93?place=w.22741310.227150955.261909\" target=\"_blank\" rel=\"noopener\">6 Gei Oni Street, Ashdod<\/a>.
