GAMEMAX GS Series SFX Power Supply 650W, Full Modular, 80 Plus Gold PSU (GS-650G BK)

Great value for money. I was a little skeptical at first because it's a lesser-known brand they seem to have even much less sales in their home market.

I was a bit wary of the quality given reviews across the Internet for older GameMax products, but so far it has worked great. At half the cost of a major maker, this is a great deal if it keeps working. My motherboard monitoring hasn't shown any spikes across all three voltages in a few weeks, and operation has been quiet.This includes short cables for sff builds. I think bottom-mounted PSU setups might struggle to get the CPU 8-pin connector to reach. I have two complaints about the GPU cables. First, they only include one 1:1 6+2-pin and one 1:2 6+2-pin. I would prefer two or three 1:1 cables to avoid the bad appearance of a dangling cable end, and because technically 1:2 is not in spec for the PCI cable's rated maximum voltage unless it's two parallel cables routed together in one sleeve (it's not here). Second, there is a port for 12vHPWR, but no cable included. I assume this is because it's cheaper for them to use the same power panel output as the higher voltage variants in manufacturing, as anything that needs the new connector will run a 650W power supply on the ragged edge of rated capacity. I'd prefer they just didn't offer the ATX 3.0 on this model, or included the cable, none of the in between weirdness.

Got a used and covered in dog hair product, gross, Update just looked even further and found someone had gotten the new power supply and returned their old one!, then i got shipped their old one.!

Used to replace a dead Thermaltake PSU on a old mini ITX build (4790k and 1070) without breaking the bank.

The product description on the Gamemax web site states that this PSU includes an ATX-to-SFX adapter. There was no such adapter in the product I received. CAVEAT EMPTOR!Follow up: I had an exchange of emails with Gamemax customer service about the missing adapter. At first they just blew me off. After I insisted that their product description included the adapter, they said they will fix the description. Well, they should give me the adapter as described!

Great PSU for the money, I had bought a different brand for twice the money for the virtual same result. Super quiet under load and it looks great on my all white PC.

Installed this in my build two days ago and so far nothing has blown up. I'm not running anything particularly power hungry (Ryzen 5 5500, RX 6600 XT, two 2.5" drives) so I don't expect to have any issues. It's way cheaper than most other SFX options and it was delivered much faster too.The cables included are pretty decent. I had to route the CPU cable through the front of the case because it was a bit short but your mileage may vary depending on your specific case's design. One note is that I wish the SATA cables were more low profile so they could fit tighter spaces, considering it's an SFX power supply.Update 1 month in:My one complaint woth this power supply is that its not very quiet. I've noticed sometimes there's a pretty audible inductor whine. Also the fan runs constantly which in addition to the inductor whine can be louder than the background noise. It's usually masked by the case fans at higher loads but when idling it can get a bit distracting if I'm not listening to anything else or wearing headphones.

This power supply worked for all of 2 weeks before spontaneously failing/letting out the blue smoke. THANKFULLY it failed without taking down the rest of the computer with it, but I won’t be buying another.
