Corsair SF750 or CoolerMaster V850 SFX?

[MarvintheParrot]

Hi! Im looking for an SFX PSU to replace my current 650 watt SFX PSU. For whatever reason 650W isnt cutting it anymore, and when I used two PSU's (One external for experiment purposes) games such as AC Valhalla worked fine, but with just the 650W one, it would BSOD on bootup of AC. Which of the two PSU's would be a better option? The Corsair one has better reviews and I trust Corsair more, and the CM one has more watts and has worse reviews. Thanks for any help!

 

My specs:

 

R5 3600

Asus B550-a gaming

Asus LC240 AIO

16GB Corsair vengance pro RGB

256GB M.2

2TB HDD (7.2k)

RTX 3060 ti

9 QL120

They're both on par with each other in the Tier list as being among the best in SFX PSUs. Like you though, I would put my trust more into the Corsair side.

BSOD is not a PSU issue and SGX650 should handle a 3060 Ti easily.

Check the RAM, update motheboard BIOS, that kind of things.

According to jonnyguru, trying to squeeze more than 650w out of an 80+ gold SFX PSU is not a good idea.
Hence why the SF750 is 80+ Platinum.
And iirc, he also said that 750W is the most one can safely "cram" into a true SFX unit.

I don't want to sound like a fanboy, but I trust him on that.
If you ever find yourself buying a new PSU, try to avoid the Cooler Master V850 SFX and go for the SF750 Platinum.

Check the error message the BSOD gives, that will tell you what the issue is.

In fact, the V850 is 80plus platinum

 

But I agree. I've seen a lot of reviews about V SFX being overly loud with stupid fan controllers.

And for that PC spec, maybe 600W would be enough. First, make sure there are no problems with the old PSU.

What's the current 650W SFX PSU?  You only have a 3060 Ti. Just because it's "650W" doesn't mean that it's equal to all other 650W PSUs in the universe.

I guess it's the Seasonic SGX650 as mentioned in his sig.

I personally couldn't find any (decent) review of it, not even a Cybenetics report of the 850w unit, but since you're the final boss of review hunting, I guess you found some review somewhere
Any idea why Cooler Master is marketing it as 80+gold instead of 80+plat ?

The 80+ report says Platinum.

• Cooler Master
• MPY-8501-SFHAGV
• ATX12V
• 850
• 87.94%
• 91.16%
• 92.22%
• 89.59%
• Platinum
• 01/24/2020

 

It only passed for Platinum at 50% load by 0.22% and at 100% load by 0.59%. The unit sampled only just makes it over the 80+ Platinum requirements and it's possible different units Cooler Master tested internally didn't match that which is why they're selling it as 80+ Gold.

The only available decent reviews are of 2 seperate things (and not complete reviews). A video about the fan issues and the revised edition where the noise issues are fixed. The first video is from machines&more. Just proof that the company that actually makes the psu is fast to respond. And the second video from Aris which is a test of it vs other PSUs using a 3090 (checking for transient issues I guess, and generally just testing high consumption PSUs)

 

The one reason I think MWE V.2 units and V-series V.2 units (generally all the new Cooler Master stuff made by Gospower) are a good buy is that even though there issues with initial production units, is because the following 2 things stand out:

 

1. MWE White/Bronze are over-engineered for where they fall in their respective price class, and both White and Bronze are basically between bronze and silver in efficiency, and have more in common with more expensive PSUs than their respective competition (all the white units have been rebranded into bronze recently anyway).

 

2. Gospower is really fast to respond, revise and promise to release new versions as soon as an issue pops up (Coil whine due to high ripple and other incorrectly set stuff on the White/Bronze).

 

3. Gospower is really fast to respond, revise and actually release new versions as soon as an issue pops up (in the case of the SFX model, where they changed the fan behavior to fix the noise issues.

 

All of this points to Gospower being very eager to prove themselves, gain a foothold in the market, and gain a good reputation, which is always a good sign. Cooler Master is either playing ball (or guiding this) as smoothly as Fractal Design and there's no Gigabyte-like saving face shenanigans at play.

And most importantly the usual unpredictable timeframe for when old stock should disappear from bigger markets is mute due to the insane demand, and there's almost certainly no old stock of any of these PSUs in big markets (and frankly other than like 400-500w models, I doubt there's any old stock in smaller markets as well).

Interesting to see how diligent Gospower is, I had no idea they were that open to change.

The main problem with them is their lack of experience.
We recently found out that even a veteran OEM like CWT is capable of designing problematic SFX PSUs...
I wish Gospower success, still, given how difficult the task seems to be, I wouldn't buy an SFX PSU designed by them.

I'm curious what they've done to the V1100 SFX
