Power supplies are often the most overlooked component in PC construction. That's a mistake. Power supplies may not be the most exciting or attractive component, but a good power supply can often be the difference between a robust machine and a nightmarish crash with problems that are hard to diagnose.

More than that, a power supply that provides the stable voltage you need, when you need it, is dependent on all of your important components. If you are building a new rig or preparing for a major upgrade, you owe it to yourself to get the very best PSU at a great price.

Fortunately, these two units are more than up to the task of providing adequate power for demanding systems, and both are now available at significant discounts. [The Super Flower Leadex V Platinum Pro 1000 W is currently on sale at Newegg for $150 with a promotional code. A few years ago, a 1000 W PSU would have been considered overkill, but in a world of RTX 4090s and Core i9 14900Ks, greater wattage for high-end builds is much more of a requirement than ever before.

This Super Flower unit is 80 Plus Platinum certified, has a fully modular design and plenty of cables. Unlike many high-power PSUs, it is only 130 mm long and will have no problem fitting into a typical ATX or Micro ATX case with standard-sized PSU bays.

Cooling is maintained by a 120 mm fan with an intelligent thermal control system to keep decibel levels down. This is a powerful PSU with excellent table manners and can easily install large wattages without much fuss. [So while it has the power to run the RTX 4090 at its highest output, you'll need to use the adapter included with the card.

But what if you want something really powerful? [It may be overkill for most systems, but if you want to build something amazingly well-equipped, or if you want to buy now and forget about power requirements for a while, this will do the trick.

Huge wattage aside, this massive unit is very overbuilt and should give you the peace of mind that it will provide excellent voltage levels for years to come.

Everything about this power supply is built to last, including high-quality Japanese capacitors, a 140mm twin ball bearing fan, and Infineon's CoolMOS and CoolSet components. However, it is very long (220 mm), so be sure to measure your case before purchasing.

Also, like the other Super Flower models above, this model does not come with a dedicated ATX 3.0 standard 12VHPRW socket.

With a promotional code, this unit is currently available at Newegg for $250. This may seem like a lot of money for a PSU, but for something with this level of power delivery and this kind of reliability, it is not a small price to pay. However, if you were to buy a component that was too powerful and excessive for your purposes, this PSU would definitely be it.

Two powerful PSUs, two heavily discounted prices. If you're looking for ultimate power at the best price right now, you've come to the right place.
