ATX power supplies on Prime Day: These offers are worth it and you should avoid them!

Also with them power supplies call the amazon sirens surfing internet sailors to the Prime Days am July 12th and 13th. Are the offers useful or are the supposed treasures also complete rubbish? Spoiler alert: Yes, You shouldn’t strike blindlyespecially at the power supplies.

Not everything that shines with a discount sign is also a gold (power supply) piece. Discount campaigns should therefore always be cross-checked with other platforms and price history. In our Amazon Prime Ticker you will also find other topics and tips around the hot phase of the Amazon Prime Days.

Brief overview: What should be considered when buying a power supply unit?

As part of a new computer speaks against an oversized power supply with an actually too high wattage Nothing, except for the higher price and in individual cases the dimensions of the power supply. There are SFX power supplies for particularly small ITX builds, while the much quieter standard ATX PSUs should generally be used for the usual midi and big tower cases. With the power supply units, the new Intel ATX specification 3.0 creates a semi-optimistic mood, which you should hardly let irritate with current computers.

Everything about ATX 3.0 can be found in this video

Avoid such power packs if possible

In order for the other core components to function properly, the power supply must perform properly without staggering outside of specifications, permanently damaging the hardware through improper manufacturing, or bluntly ignoring safety authorities. Therefore, avoid cheap no-name power supplies if possible and rather stick to discount campaigns from well-known manufacturers such as Be Quiet, Corsair, MSI, Seasonic (often also as OEM partners for brands such as Asus, EVGA, Deepcool etc.) and Co. Cheap power supply offers like Mars Gaming or Aerocool should also be treated with caution on Amazon Prime Days.

For unknown, bad “China Firecrackers”that from the factory at worst, life-threatening can be made, the comparatively small savings are not worthwhile. The actual problems and dangers, such as potentially faulty protective circuits, only become visible over time or when the hardware burns.

For 80+ certification, you should aim for at least that Gold logo or better (Platinum/Titanium), especially if you’re looking for a power supply for your mainframe that runs all day often. The better the certification, the more efficient and, as a rule, the higher the quality of the topologies installed inside – the higher efficiency also reduces the secondary waste heat that would otherwise occur, so that the cooling can run more smoothly. The longer you use your calculator actively use them, efficiency becomes all the more important and after a certain time also the saving of the electricity costs that would otherwise be due. While the silver class is considered virtually extinct, a small proportion remains bronze power supplies available in the market you if possible for modern gaming computers only as an emergency or temporary solution should use. Exceptions can be ancient, office or super low computers.

What efficiency and what watt class should it be?

There is hardly any such thing as “too efficient” or “too much possible performance” because primarily the price is the only deterrent. For example, speaks for an actually oversized power supply the easier upgrading of the computer with later, more power-hungry components such as the graphics card. At this point, we recommend taking a quick look at our ATX 3.0 video so you can gauge for yourself what to expect from PSUs with ATX 3.0 and PCI-E 5.0 GPUs in the future. The practical difference between gold and platinum power supplies is often price-wise, but there is a tendency Platinum power supplies to be significantly quieter than their gold siblings. Titanium is to be seen as the crowning glory in every respect and costs accordingly. A Gold power supply is ideal for most usersfor some a platinum representative and the Titanium class is at more upscale to locate users.

Using the manufacturer’s information for the individual hardware parts, you can calculate how much energy your system actually needs. But you can also go for a rough estimate Online Performance Calculator use, which many manufacturers also offer. In addition to your system, calculate a small buffer of about 10 to 20 percent in order to forestall thirsty hardware when upgrading. With a thumbs up, you can also calculate the TDP of the graphics card and processor by a factor of approximately 1.5. The watt classes from 600 to 850 watts are good reference points for modern computers.

Don’t give too much thought to the blanket advice not to use an oversized power supply. In cases where that the same quality (or even better) power supply costs less, as in the example of the 850 watt variant compared to 750 watts here at Corsair within Amazon Prime Day, you should go straight to the better power supply.

Caution: When it comes to power-hungry components, it’s not just the total power of the power supply that matters, but also the nominal power of each rail. With single-rail power supplies, with only one 12-volt rail, in most cases more than 90 percent of the total power is available, with multi-rail PSUs, on the other hand, the power is divided up so that when you connect the graphics card to the distribution should be considered. Of the The difference between single and multi-rail power supplies hardly plays a significant role in the role and is more of a question of faith. As long as you pay attention to the type of power supply when connecting, you don’t have to pay attention to anything else – so if you have a good offer, you can access it regardless.

Bring on the power pack offers: These offers are worth something
