Until recently, buying a PSU with a four-digit wattage was perhaps most useful for boasting among fellow hardware enthusiasts – there was barely any real need for such high wattages. However, Bitcoin mining and Altcoin mining have changed that.
Although high-wattage power supplies get most of the glory, we take our hats off to small, efficient solutions offering more practical output. We take four sub-450 W PSUs and run them through our benchmark suite to see if we can determine a winner.
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.
There’s an enormous amount of aftermarket coolers available to those wanting more performance or lower temperatures. The market’s currently dominated by tower coolers, and top coolers have fallen out of favor. Rightfully so? We find out.
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.
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.
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.
