    • Good PSU from a Great Company
Size: 650W
FSP powersupplies are the only PSUs i've ever used. This is nothing short of the best. It's actually rated for it's advertised wattage. They are more expensive then other companies, and there's a reason. They are pretty much the only company that has any buisness being in the Powersupply game. Pros- SFX for Itx Builds, modular, 650w 80+gold, fan is quiet, and isn't even on until it starts heating up, which only happens of you're pushing it. Cons-Cables are way too long. The CPU 8pin is 700mm long, which is absolutely insane for an ITX build. It also is an 8 pin, with a 2nd 4+4 attached to it, which is dumb, again because it's ITX and there is no ITX motherboard that uses 8+4 or 8+8. The sata cables are both molex, and one has a floppy connector on it, so if you're running hardware that old, i guess thats okay. But again it's an ITX PSU, so there is once again no need for a 700mm cable with 100mm of cable between each connector. Other than that no problems. ... show more

    • Perfect Fit for ReadyNAS Pro Pioneer (6-Bay)
Regarding the fit in a ReadyNAS Pro Pioneer (6-Bay): 1. Dimensions are a perfect match for the original Seasonic SS-300SFD. 2. Cooling fan does not extend out like the original. The fan is not perfectly centered in the opening in the ReadyNAS case, but it is adequate and does not require case modifications. The fan ends up about 3/8" (1 cm) higher (upward with respect to the case) than the original fan. 3. It is a direct replacement with no extra cables or extensions required. 4. It has (3) 4-pin hard drive connectors, so no extra 2-to-1 adapters are required. 5. It has enough length on the 24-pin motherboard connector that no extension cable is required. 6. Cables exit upward in the same location as the original power supply, allowing clearance for the case cooling fan. 7. The only difference is that the IEC connector is flipped (rotated 180 degrees on its centerline), so care must be taken to connect the internal power cable extension wires correctly. The connector on this power supply is on the bottom, same as the original. Durability and longevity of the power supply is unknown at this time. ... show more

    • Bought to upgrade my MSI Trident A+9th
Size: 650W
Wanted to give my system a solid power supply to upgrade to a Nvidia 3070 in the future, it took a bit of effort, the cables are a bit too long and bulky, but it worked for me.

    • Great modular PSU with a small form factor
Size: 650W
I was on the hunt for a smaller PSU for my mATX gaming box. I paired this with a i5-9600k cpu and an Asus TUF GTX 1660 Super OC GPU. Love the modular design, will make hiding the cords easy. It is also quite. It comes with a plate to attach so you can use it in an ATX case, but check your sizes/cutouts of your case because it is a smaller form factor, ie the fan is smaller if you have a special cutout for a regular ATX sized fan, you may have gaps. It worked perfectly with mine. A bit on the higher price level, but I researched these fans and they are good quality with lots of good reviews. Highly recommend. ... show more

    • Best mix of price, power and size
Size: 650W
My external GPU system was unreliable. I needed a PSU this specific size, and more than 500W. This fit the bill, and now the graphics card is working perfectly. A little more expensive, but seems to have been worth it.

    • Very Efficient ITX Power Supply
Size: 650W
I installed this product in a Lian Li ITX case, as part of an Intel 8600K based system. Using a power block to test the FSP PS beforehand, it worked right out of the box. The internal cooling fan doesn't start spinning until the power supply is under at least 30 percent load, and has been designed to operate accordingly. After one week of operation -- no problems. Recommend! ... show more
