Efficiency is upgraded to 80 Plus Platinum, from 80 Plus Gold that the previous AURUM series featured. Unfortunately, FSP does not give any info about the operating temperature range. Nevertheless, we will test it at above 40°C ambient, like we do with all PSUs. All protection features besides OTP (Over Temperature Protection) are present in this unit, and the cooling fan utilizes a high-quality Fluid Dynamic Bearing for increased lifetime and reduced output noise.
The dimensions of the unit are the standard ones. All normal cases will accommodate it without any problems. Its weight is on the low side since it uses small heatsinks due to the ultra-high efficiency it can achieve. The warranty is set to five years. The MRVP of this unit is $ 135 at the time of review.
|FSP PT-650M Power Specs|
|Total Max. Power||650W|
There are four +12V rails which can output 576 W combined, much less than the 650 W of the unit's total capacity. The minor rails are restricted to 100 W, but you won't need more in a contemporary system. The 5VSB rail is strong enough with 3 A maximum current output.
Cables & Connectors, Power Distribution
|ATX connector (550mm)||20+4 pin|
|4+4 pin EPS12V/ATX12V (650mm)||1|
|6+2 pin PCIe (560mm)||1|
|6+2 pin PCIe (500mm)||1|
|4 pin Molex (550mm+150mm)||2|
|4 pin Molex (550mm+150mm) / FDD(+150mm)||2 / 1|
Unfortunately, FSP decided to equip the unit with only two PCIe connectors. This is a weird design choice that cripples the PSU's usability. We think that it could easily handle four PCIe connectors since it can deliver near 600 W with the +12 V rails, something that would allow its future buyer to install two VGAs with dual-power sockets each. The two PCIe connectors available with this unit would, on the other hand, only support a single VGA with dual PCIe inputs. Thankfully, at least the peripheral and SATA connectors are adequate for the unit's capacity.
As you can see, all cables are of sufficient length, and FSP was kind enough to provide two SATA cables with different distances amongst their connectors. The first SATA cable sports short distances amongst its connectors, something convenient if you have to power multiple HDDs that are close to each other. On the other cable, distances amongst connectors are three times larger in order to be able to connect SATA devices that are not too close to another (e.g. a SATA DVD-RW and an SSD/HDD). All connectors use 18AWG gauges; the minimum required by ATX spec.

Power distribution is ideal since the EPS connector is powered separately with the PCIe connectors also being powered through a different rail, each. The last +12V rail powers the 24 pin ATX connector, along with all SATA and peripheral connectors.
