I love the color and price but I’m skeptical of Gamemaxx. I remember them having really trash PSUs coming up.

Some useful design info but no words about OEM / platform...
I wish, before posting these press releases mostly verbatim, TPU or others would ask for some additional info...

Suspect they are still Gamemax / Sohoo internal efforts.

These GameMax SFX PSUs claim good certification and extensive protection. Good to see.
However, not found on the Cybenetics database while past tested GameMax PSUs didn't seem to meet GS SFX Gold Series claimed standards.
Would like to see Cybenetics test report.

After willingly paying the $250-400 premium just to get an SFF case, mITX board, and SFX PSU why would you want to risk the entire build and use an unknown PSU from a brand with some dud PSUs on record just to save yourself a measly $50?

Clearly, you're not bargain-hunting on a tight budget if you've gone down the SFF mITX+SFX route. Corsiar SF750 for $179 with an absolutely flawless track record and nothing but great reviews.

Hmmm. This PSU is meant for people on (thight) budget.... The Cpu and the MB use 3x 8 pins connectors nowadays. With this PSU you have an abysmal 3x 8 pin + the modern 12+4 pin connector for nvidia graphics cards. So no love for coming AMD and Intel graphics cards. How stupid is that? And you can't even power up your nvidia graphics cards if it have 8 pin connectors (you are on budget). Modern means better. This PSU's should have come with only 8-pins connectors instead for the 12+4 pin connector. Just put with 8-pins to 12+4 pin adapter cable. How stupid can some (design) engineers be? Make an PSU for bugget and you can't use new or older cheaper graphics cards (with 8-pin connectors). Give me an cheap new or used Corsair PSU any day over this failure.

Yes you get an pigtail (4 + 4 Pin) ATX 12V Power cable for powering the Cpu but I don't like this sorts of cheapo made design solution. Even with their 850W model.

Edit.

People on a tight budget don't shop for SFF cases, period.

Cheap MicroATX case? $50​

Cheap SFF case needing mITX board and SFF PSU with PCIe 4.0 riser cable? $200​

​

Cheap MicroATX B650 board? $89​

Cheap mITX B650 board? $219​

​

Cheap, but reasonable quality ATX 750W power supply? $75​

Cheap, unknown quality SFX 750W PSU from GameMAX? $128.​

There is nothing cheap about SFF at all. If you're on a tight budget you just need to stay away from any SFF cases that require an SFX power supply. There are some cheaper SFF cases that support ATX PSUs, but they're not relevant to this discussion about an SFX PSU

The Cpu and the MB use 3x 8 pins connectors nowadays. With this PSU you have an abysmal 3x 8 pin + the modern 12+4 pin connector for nvidia graphics cards. So no love for coming AMD and Intel graphics cards.

No, I think it's normal for SFX. 3x CPU/PCIe is pretty common even on ATX PSUs of these ratings. Yes, there are some motherboards that take 3x8-pin but they're typically OC-focused Intel boards for the 13th/14th-gen 353W CPU when PL1 and PL2 are unlocked. You're not going to use such a board in an SFF where cooling space is limited.

As for the CPU/PCIe cables, you'd most likely need one cable for the CPU and two PCIe cables ought to provide a bare minimum of 375W to any GPU, even if they've used single-connector per wire.
