4 out of 5 eggsNot compatible with all ITX boards

Pros: Fairly quiet, well constructed.

Cons: Lacks the -5v pin on the ATX header. Some older Atom boards still require this as the LPC is on an ISA bridge (and is the only thing on the ISA). This prevents the board from ever powering up on this supply.

Other Thoughts: Overall a good supply, but not compatible with all ITX builds.

5 out of 5 eggsSurprisingly awesome!

Pros: For starters, I voided my warranty by purposely cutting and removing the outer shell for space purposes. its small to begin with but I need every mm. the build before and after is still great after 6 months of abuse. powers my mini itx NES customer case with components I thought would push it, but doesn't seem to be the case here. the fan is tiny quiet and keeps cool enough with very little air flow (less than 40c) .

Cons: none so far. hope it stands the test of time

3 out of 5 eggsNote on sizing

Pros: I presume it is a good psu...

Cons: I didn't catch the issue with the sizing. I got it for a mini-ITX case, since this has mini-ITX in the name. But mini-ITX doesn't actually standardize PSUs, and this should properly just be called Flex-ATX. (I never built a mini-ITX system before)

It doesn't fit most (any?) mini-ITX cases - certainly not ones designed to have a full gaming rig stuffed in. There don't appear to be any brackets available to make it fit either.

This is discussed on the QA page here, too bad I didn't look...

Other Thoughts: Sorry for the low review score, I have no reason think it isn't a fine PSU, but I hope people will notice this before they make this mistake

5 out of 5 eggsSolid unit

Pros: Powering my i5 and GTX 750 ti along with a bunch of fans and usb devices.

Cons: None

Other Thoughts: Replacing the fan is easy too. Not that you need to, but I had to for my specific build.

5 out of 5 eggsWorks great, long cables, not modular

Pros: Has been working well for several months. Installed it in my own custom built ITX case: 8x10.25" and 5.25" high.
Rails are strong enough to power my new i7 Haswell, along with a 750Ti graphics card. The 750Ti is a great option if you need a low watt card. Also installed two 120mm fans for extra cooling, along with a Zalman cooler.

Cons: Power supply seems to be designed for a large-format ITX case. It's got long cables, so you must plan your wiring very carefully when using in a micro case. I didn't need all plugs provided.
Knew about the cabling before purchase. So not nuking any stars. But wish there were modular power supplies available for tiny cases.

Other Thoughts: The power supply must have a great internal fan. It's cover never feels warm.

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....
