How does a power supply work? Why is it important to choose a sufficiently powerful and efficient model? We guide you through discussions of efficiency and tips for getting the best deal before we go on to explain why less can be more in the PSU market.
EVGA recently enriched its P2 line with three new members, featuring 650W, 750W and 850W capacities. All three, like the other P2 models, are made by Super Flower and feature Platinum efficiency. Today we're testing the 850 P2.
Have you ever bought a computer case with a proprietary PSU form factor? What do you do when it eventually wears out? One option is to repair it.
Ready for part two of our low-cost power supply round-up? Here are four more products, including Seasonic's SSR-360GP, which is 80 PLUS Gold-certified. Is this little 360 W PSU the bargain of the century, or is its Gold label simply pyrite?
Power supply manufacturers condition us to think that efficiency is the one variable you need to pay the most attention to. But we have a suite of tests that more thoroughly taxes PSUs. Can these four inexpensive units under $70 make it through unscathed?
A good power supply doesn't just provide you with ample output. Increasingly, vendors have put a bigger emphasis on delivering power more efficiently, too. We're testing five 80 PLUS Platinum-rated power supplies in the 550- to 600-watt range.
Do you think that all power supplies are manufactured by the brand on the label? Think again. We show what makes a good PSU and reveal who builds them. You can actually find lots of quality (instead of just scrap metal) behind some of the budget labels.
The power supply typically isn't the noisiest component in a high-end PC. Nevertheless, many folks are serious about cutting noise, and go the extra mile for a quiet system. We step in with a comparison of two silent models against one low-noise PSU.
Gamers and enthusiasts are always on the lookout for crème de la crème hardware. It's easy to pick winning CPUs and graphics cards; less so for PSUs. We put four 80 PLUS Gold devices from Antec, FSP, Seasonic, and SilverStone under the magnifying glass.
Battery life is always such a big deal in our mobile coverage (often because gaming systems fall so short). But don't feel limited by the built-in power source. Today we round up 15 external batteries that can keep you running longer away from a socket.
We received a trio of 1000 W power supplies priced between $200 and $300, so we ran them through our usual suite of tests to see if they really live up to their 80 PLUS Gold certifications. Surprisingly, all three hiccuped during efficiency testing.
Gamers demand a lot from their computers, starting with the PSU. Therefore, almost every PSU manufacturer sells products optimized for gaming PCs. We introduce ripple and noise testing in this roundup to further improve our power supply evaluations.
It's downright negligent to ignore the power needs of your high-end hardware. While many power users go to the trouble of tracking down solid PSUs, we recommend going a step further and investing in battery backup. We round up four enthusiast units.
Did you think all power supplies were manufactured by the brand selling them? We show you what makes a good PSU and reveal who actually builds PSUs. You can actually find lots of quality, instead of just scrap metal, behind some of the budget labels.
You probably know Corsair best for its memory products, power supplies, and SSDs. But now the company is jumping into the crowded headset market with an unassuming entry that’s both affordable and capable of offering great sound quality.
Enthusiasts often say that you can never have too much performance. However, a 500W power supply is perfectly ample for a majority of mid-range PCs. This is one of those cases where a solid ratio of performance to price is preferable to gross excess.
