BeQuiet SFX-L 500W


When Silverstone kicked off their whole push for more power in small form factors, I thought it was a brilliant idea. They cast a light on a long neglected part of this industry, and I thought we'd get a nice long list of other companies jumping into...

excellent voltage regulation ; excellent ripple control ; fully modular ; very good build quality ; lots of accessories

way too many big names are still missing from the SFX market

BeQuiet's adventures into the SFX-L market seem to be heading in the right direction with this unit. Based on a platform we already know can do up to 700 watts, this little guy is a pretty solid entry into a market that is still under-supplied by most...

Expert review by : OklahomaWolf (



Once in a while, it's good to go off the beaten path and review the units that manufacturers won't send us. Not too long ago, I blew up a Coolmax unit that proved that sometimes there is a good reason for not sending out review samples. Today's test...

extremely affordable ; good looking ; excellent 5V stability ; excellent minor rail ripple suppression ; fully sleeved cables

no heatsink on bridge rectifier

EVGA's older and less efficient precursor to the 500B is no great gift to the world of power supplies. There are no new groundbreaking technologies in the housing. You don't get a bag full of stickers, zip ties, posters, or any other tomfoolery that...

Cougar GX-S 500W


We've got another kitty cat to throw on the load tester today... not a real one, of course. No, today we're taking a peek at Cougar's new GX-S line at five hundred watts. This is a small fry, clocking in at only 140mm deep. Will we get 80 Plus Gold...

very good voltage stability ; very good to excellent ripple suppression ; no problems meeting Gold efficiency ; shallow housing depth ; love that fan

the unit was a little loosey goosey with the overshoot transient tests - all three of them

Cougar's little 80 Plus Gold GX-S unit has a lot going for it. It's very stable in regulation, it's quiet, it runs cool, and holds the ripple well in check. It does have a few edges that could use some sanding down, like that little rise time and...

Super Flower Golden Silent 500W Fanless


Superflower comes to us today bearing fanless goodness - a 500 watt 80 Plus Platinum take on their newest line of Platinum certified units. Come on in, and we'll see if taking the fan out of one of these awesome units was a good idea.

fanless ; Platinum efficiency ; build quality ; low ripple ; excellent voltage stability

a little pricey ; not available in North America

Superflower continues its winning streak with the fanless Golden Silent 500 watt unit. Like its fanned cousins, it's an exceptionally good unit that takes an already fantastic platform and takes it to the next logical place - fanlessness. If you need...
