Flex ATX is an exciting form factor overall, and while good for servers, it is a bit tougher to justify for most consumers. That would be what I would say some time ago as most Flex ATX cases have PSU's included, now we are getting not just more PSU options in the Flex ATX form factor, we are getting ones which are not finished in raw metal but actual black painted like a PSU we have come to expect from SFX and ATX. I do hope that with new Flex ATX models coming around, we can see more capable units along with smaller form factor or slimline chassis, which can support enthusiasts or gaming-grade systems to build upon.
Now we get to what we like about the FlexGURU from FSP. What we like about the FlexGURU first and foremost is the fact that it brings new life to the Flex ATX space with modular and black color PSUs, which will make a good foundation for ultra SFF or slimline PC builders. I really do hope this trend will continue with more capable units like what EVGA offered in their Hadron chassis. Good high output and decent looking Flex ATX supplies are hard to come by, so this is welcomed.
Now, we discuss what we don't like or would like to see improved. First up for the FlexGURU would be the omission of the floppy connector. Also, a way to break out or remove the ancillary peripheral connector so that you do not have six extra connectors and three leads to manage due to the need for a single SATA connection for an HDD or SSD. There is not a lot else I could choose to pick apart besides the fact that at least a 6-pin PCIe connector would be a welcome inclusion as HTPC/SFF gaming rigs are becoming increasingly popular. I do know that at 300W, it's not really "made for" the load of a GPU, but it is something I would like to see along with a higher capacity offering to enable the SFF gaming potential.
The price point for the FlexGURU I feel is rational but at the high-end. I give some leeway here as there's not a lot of competition in this space since most Flex ATX PSUs are bare metal finish grey and not very consumer-oriented. The only modular unit we found from SilverStone of a similar spec was a raw version that was spec'd for industrial use. This being a consumer unit and having some peace of mind features for consumers helps carve out a space or niche as it may be for the FSP FlexGURU.
Not everyone needs Flex ATX. Still, for the SFF community, I hope this is just the beginning of the trend from FSP, enabling more power and SFF gaming rig capability with the FlexGURU series of power supplies.

The Bottom Line
