This is their "300W" model. But if you check the amps on its dual +12V rails you will find that it exceeds many 500W models, such as the XClio GoodPower 500W and the ThermalTake TR2-500W. It is very similar to the Fortron 350W model. $30

This is their "350W" model, with Dual +12V rails @ 16 and 18 AMPs. Very similar (if not identical) to the Fortron AX400. $31.99

This is their "400W" model, but it too has an extremely high amp rating on the +12V rail...close to the Antec TruePower II 550. It is eerily similar to the Fortron AX450PN, rated at 450W. The Sparkle, however, sells for $43.99.

Don't see much difference, eh?
 
my bad guess i was looking at the fx series, silly not to spend a few bucks more and get a much more efficient PSU IMHO, but still a great buy for a high quality PSU.
 
"De-rate 2W/C from +25°C to +50°C"

Since these PSU ratings and MTBFs are based on 25°C conditions, it's not really realistic. For instance, the 400W model linked would most likely run at 45C-55C conditions (PSUs run hot under significant loads), which is 2W*20C or 2W*30C less.. so in actuality it would be about 350W of real power.

Still a good deal for a good PSU, but for important systems you should stick with PSUs from companies like PCP&C which rate their PSUs @ 50C temperatures :thumbsup:

'Few' bucks..? FX (aka Epsilon) line-up only has 600W and 700W model, and the cheap one (600W) is $ 139.99 at Newegg. This post is about a great PSU for less than 50 bucks, and you want to say 89.99 more is few bucks more? Hope you were kidding 🙂
 
I wasnt joking, but i wasnt trying to thread crap either, as i said it is a great deal for those looking for a high quality psu at a low entry price.
 
Wait what's the difference between these and the Fortron Source Group? I thought they were made by the same company? The efficiency ratings in the links above are the same > 70%.

You are quite correct and in line with he reasoning (or advertizing) of the higher end guys (a la ps power and cooling). Still a great deal for people with medium end rigs.

Yes, they are same company. I believe Fortron Source Group (FSP) is a mother company, and Sparkle is a company under FSP that sells in various markets that FSP is not estabilshed. (Or vise-versa)

For example, in Korea, you can only find Sparkle brand. But the line-up and built-quality is exactly same as FSP-branded ones. It's kinda interesting that both Sparkle and FSP brand is available in US though.

Fortron usually underrates their PSUs. How else can you explain the FX700-GLN's spec sheet statement that it loses 100W from 25 to 35C? In actuality, it's 50W from 40 to 50C, IIRC.
 
Fortron underrates, but what about Sparke? How loud are these power supplies? I have an older Sparkle 350W PSU and it is really loud even though it just has one 80mm fan.

The efficiency ratings are a marketing joke. People don't even know what they mean:



PSU Efficiency:
Minimum efficiency under typical load has increased from 60% in the v1.3 spec, to 70% in the v2.01 spec, to 72% in the v2.2 spec. The more efficient the power supply, the better off you will be in the long-run when it comes to paying your electric bill. The percent of energy not converted is lost as heat, and unless you live in a very cold area then the additional heat is not very helpful.

The difference between 70% and 85% isn't that much when it comes time to pay the electric bill.

I have the fortron AX400PN from newegg and it is LOUD even under very light load (on board video, 1 HD, 1 DVD). It has 1x120mm. I replaced the fan.
 
substance12: since when did you ever expect a PSU with 80mm fan to be silent? 120 mm are quiet but 80mm are certainly not.
