14 DAY TRIAL // The more efficient a power supply is, the more expensive it becomes. But the extra cost is usually recovered through sheer power bill savings in just a month or two, after which you're basically making a profit, in a really roundabout way. 80 Plus Titanium PSUs like the one FSP has just unveiled are the best.
The 80 Plus certification rating ranks power supply units in terms of how much power they waste. The less it is, the higher the ranking becomes.
To get 80 Plus Titanium rating, the highest of six ranks (the other are 80 Plus, 80 Plus Bronze, 80 Plus Silver, 80 Plus Gold, 80 Plus Platinum), the power lost needs to be very low indeed.
Specifically, the efficiency has to be, when plugged into a 115V internal non-redundant power socket, of 90% at 10% load, 92% at 20% load, 94% at 50% load, and 90% at 100% load.
Similarly, on a 230V internal redundant current, the efficiency needs to be of 90%, 94%, 96% and 91%, respectively.
The FSP 400W SMPS 80 Plus Titanium PSU
The wattage of 400W might seem low, but it really isn't. While we won't advise against meeting the miniumum power requirements written on, say, NVIDIA's graphics card product pages, 400W is a comfortable wattage for a good PC. Unless you want to create a computer with multiple high-end video cards anyway.
Indeed, FSP is aiming the new 400W SMPS power supply at personal computers and office equipment. You can easily power a gaming PC with it though.
Active clamp forward topology design guidelines were followed closely, and the Copper Bus Bar was placed in such a way as to create negative air pressure, actively cooling the component constantly, to an even better extent than normal.
Keep in mind that SMPS is not the product name of the PSU. That's actually FSP400-60GTAA, so look it up on whatever retailer you prefer.
SMPA is short for Society for Marketing Professional Services and is a badge of honor, so to speak, to be allowed to stamp it to a power supply.
Don't bother looking for other 80 Plus Titanium PSUs of such low output, because unless someone released one without shouting about it, you won't find any.
Availability and pricing
Sadly, the SMPS 400W power supply has not been given an ETA (estimated time of arrival) or even a price yet. That could mean that shipments will begin shortly, or that FSP is waiting for the start of the new year to begin sales.
