5 out of 5 eggsGood Support

Pros: There was a small issue with the first PS I ordered.
Even though it was after 30 days, FSP honored their product and took care of the issue.
It is always good to know the company backs their products. Pretty quite too.

Cons: The first PS I got reset itself every day or so.

Other Thoughts: Running stable 24/7 for over a week now.
They replaced the original PS without hassle, gave me an RMA through email and backed their product.

5 out of 5 eggsTinny but powerful!

Pros: Great little power supply, only 6" long, and fairly quiet considering it's 40mm fan. powering my HTPC/gaming rig. Specs ASUS H61, Core i3-2130, 8Gb of Gskill ram and a GTX 645 single slot card with a 600Gb Velociraptor HD. This power supply powers all with ease. Great product from FSP.

Cons: Cables aren't sleeved. Nothing you can't do yourself a sleeving kit.

Other Thoughts: Looking for PS for your HTPC this is the way to go. It's not designed for my case (Athenatech A1089BB.150) but with some imagination and some double sided tape it looks like it belongs there from factory.

5 out of 5 eggsSolid Quality

Pros: Flex ATX power supply. There are a couple of 1U server chassis and HTPC's out there that use a Flex ATX platform, accomodating micro-ATX and mini-ITX boards. They will -NOT- accept 1U power supplies, and so it is nice to see a good solid unit being sold to fit this platform size. It's a solid 300 watts all day, and does not have thermal issues of any kind.

Cons: None really. You may need a 4 pin PSU power extension cable, which they sell here on Newegg. Many chassis where the power supply is on the left side instead of the right side will require an extension, so that's not really a 'con'.

Other Thoughts: I picked up an Athena Flex ATX (1 U) rackmount server chassis and the included 300 watt Athena supply failed after only minutes. In my history, I've never had luck with Athena Power, however FSP, iStarUSA, and HiPRO have been outstanding units.

1 out of 5 eggs4pin DOA

Pros: Looks like a dense well built psu

Cons: Powers the motherboard, usb, fans, etc, but not the cpu. I was confused at first, tested everything, swapped ram, swapped cpus, swapped... everything, then swapped psu, instant boot....

5 out of 5 eggsVery good

Pros: I bought this to upgrade the PSU of a Gateway SX2800-01 (like an Acer Aspire X3812). There's no direct replacement for their 220W proprietary PSU made by either Lite-On or Delta. But this guy works just fine if you have fabricate a sheet metal adapter plate to line up the mounting screws without doing case mods. Search on ebaay for sellers of aftermarket 250W PSUs for Gateway to see pictures of this plate. You can get the metal plate from Home Depot and cut, drill, tap as needed. Pop rivet it onto the Mini ITX PSU. It's not as quiet as original, but you will be much happier than with an Athena one noise wise.

Black paint treatment is a nice touch.

Cons: None really.

Other Thoughts: An alternative to making the adapter mounting plate is to just transfer the guys of this PSU into the OEM one. I elected not to do this to not void the warranty but it is another option.
