How good is this psu

Just saw this psu, I know gamemax has a trash reputation, but it's platinum rated and pcie 5.0, and a really good price

Platinum is just an efficiency rating, it has zero relation to the quality of the unit.

Not great...

 

You better off spend 10 USD more for this Cooler Master PSU

or for the same price buy Segotep GM850 

https://www.amazon.com/Segotep-850W-Fully-Modular-Gaming-Certified/dp/B08F1NFSG4/ref=sr_1_10?crid=146Q9CU7W08R9&keywords=850W+PSU&qid=1689628429&sprefix=850w+psu%2Caps%2C259&sr=8-10

 

The cooler master one is B-Tier, and Segotep is speculative B-Tier

 

Here is the full PSU tier list (more updated than the one featured on LTT Forums)

the fact your power supply claims to be PCIe 5.0 is probably the best warning label to stay the fudge away from it.

 

there is no such thing as a "PCIe 5.0 power supply". PCIe generations have nothing to do with power supplies, the fact they have to advertise with that means they have nothing good to say.

 

just a fun sidenote is that this "gaming" power supply is named after a type of mission in GTA that revolves around causing as much destruction as possible...

It even blindsided me for a second before I realised its ATX 3.0 it should be advertising.  Clearly designed to "sound right" at a glance while not meaning anything.  Even more worrying to have a junk grade PSU with 12VHPWR given those connectors have barely any safety margin on a good PSU, chances of a bad one melting your GPU socket seems high.

To some extent it would be, given you need a certain quality of design to meet that requirement which inherently means it can't be complete junk.  There's two problems though:

1) It doesn't guarantee how long the components will last.
2) Junk-grade PSUs will just lie and put the label on when they don't even meet 80+ white standard.

reviews dont seem to be that bad but gamemax has an awful reputation so id still avoid unless were talking massive discount, only reason id go and buy that would be for testing just to see if its any good or not

 

look for another one around the 100$ price range, avoid paying more than 120$. As for the used market you can expect 850w to be around 50$, 1000w to be 60-80$, 1200w to be 80$ and up

 

You wont be futureproofing with 850w anyways, so prefer a used 1200w unit if you really wanna keep the thing for over 10 years, better quality psus are likely to lean towards or past 15 years, dont buy anything over 7 years old and prefer <5 years old

All new power supplies state Pcie 5.0/Atx 3.0 compliant even brands like corsair, Msi, Asus, Nzxt, Thermaltake, gigabyte and Bequiet, so what you are trying to say is i shouldn't go for any of these reputable brands simply because they state Pcie 5.0 in the title.

aside from necro'ing a thread.. there's a difference between saying it is compliant on the spec sheet, and having "PCIe 5.0 ready" at the top of your product page.

Of course not, but it doesn't alter the fact PCIe 5.0 has nothing to do with power delivery given the cards using 12VHPWR right now are actually only PCIe 4.0 cards.

 

Corsair specifically I think its because they AREN'T ATX 3.0 compliant as they just bundle the PCIe to 12VHWPR adapter cables, the PSUs don't physically support the ATX 3.0 new feature where the PSU itself triggers the 4 pin connector to tell the GPU to reduce its TDP if you have plugged in more than one GPU that might push it over the PSUs power limit otherwise.  But IMO that's a largely pointless feature as it doesn't take into account you might be still within the PSU limit based on the actual real-world load, so its limiting the GPU for nothing.

 

Personally though I think what they are doing is better given the 12VHPWR connector issues - better to only have one of them to keep an eye on than a second one at the back of the PSU where its more likely to get less airflow and be worked loose during cable management, triggering the melting problem. PCIe sockets on the PSU side are much less prone the problems, stupid to replace it with something proven to have a higher chance of problems.
