CV650 for overclock

[lenardmgtr]

Hey all! I'm building my first PC and have plans to explore overclocking my CPU, GPU, and RAM. 

• CPU: AMD Ryzen 5 3600
• GPU: Gigabyte Radeon RX 570
• RAM: HyperX Fury RGB 2x8GB 3200mHz
• Mobo: MSI B450M PRO-VDH MAX

Main concern is if the Corsair CV650 can supply enough power to overclock all my current components and have flexibility to upgrade in the future (GTX 1660 Ti and another kit of RAM), as I will most probably be upgrading. Want to avoid having to buy another PSU in the future.

 

Thanks!! :DD

definitely, with that psu you can push those parts as far as they will go. 

Hell no. That's an EXTREMELY low end and cheap unit. It is NOT meant for overclocking.

Use @ stock, do NOT attempt to push an overclock. That power supply does NOT have the voltage stability, protections or ripple suppression to safely guarantee an overclock. It can also NOT survive a lot of heat so keep that in mind. - The CV is a SUPER cheap office model, NOT a high-performance one.

I wouldn't say so, it's essentially the same as be quiet! System Power 9 for example. Not great but not terrible. CV650 is a completely different from the rest of CV and VS series.

It's a bit worse and still the cheapest bargain bin model that should even be considered. I'd this crappy unit was enough for overcloclicing and running high stress loads, then nobody would be making 200$ platinum rated units...

If you ask me, nobody needs 200$ Platinum rated PSUs in the first place. 100$ Gold units are more than enough if you don't have a multi-GPU setup. And this specific config doesn't overclock well anyway, there would be barely any difference in the power consumption.

The CPU itself or the mediocre B450 Pro VDH Max motherboard will limit your overclocking ability long before the PSU is a concern. It'll be fine.

Overclocking is not just what MHz extra you get. Memory tuning, voltage stabilization, power tuning and clockspeeds all factor in. And a good power supply can have as much as a 15% performance improvement when you're really going at it.

 

In this case, a cheap power supply may result in failure when pushing the hardware as the CV has lots of missing protections, unstable voltage under crossroads and Betty very cheap and low end Chinese capacitors

What protections is the CV650 missing that will prevent you from overclocking?

Can you provide a link to a review that tests voltage regulation in a crossload scenario for the CV650?

What brand capacitors does it use?

You're overreacting, PSUs like these are bad only if you push the PSU to the absolute limit. OP's setup only consumes about half of what the PSU is capable of, even if it's overclocked.

Just because of better PSU ? Bold claim.

The only protection it probably lacks is OTP, which doesn't affect power delivery, i just can't find spec sheet for it, perhaps @jonnyGURU could say if it does or does not have OTP.

Again, this is DC-DC PSU, there wouldn't be any problems with crossloads. There may be subpar transient response but not with this config.

Again, bold claim, you didn't see it's internals as there are no reviews, but perhaps Jon could shed some light here too.

Thank you all for the replies!

 

While there does seem to be some disagreement, I think the CV650 might be able to suit my needs just fine :DD

Are there any mATX boards you can recommend perform better? I've been looking at the mobo tier list but I'm still lost :^((( possibly something with more upgrade potential

This is good to hear! :DD Having about 325 watts headroom makes me comfortable in getting better parts in the future :^))

Here's him telling people to not use the CV on high end systems and to opt for the CX at MINIMUM.

The person who designed the power supply is is in the image above recommending its use for basic systems only. This is NOT a power supply designed for high performance and high heat statems. It's a minimally upgraded VS model and meant for office PCs with APUs or no dGPUs, not power hungry overclocked and hig heat gaming systems.

It's group regulated btw

I know a guy in the office who pushed his out if AatX spec with, admittedly, higher heat/power components. He had a 9700KF and 1070 To running on it but it was causing crashes and he took a multimeter. UVP didn't kick in and he measures 11.3 Volta on the +12v rail so the board was cutting power to the system to protect it

The CV 650W is DC-DC on the secondary. Do you not bother doing even basic research? Cybenetics did testing for it.

Jonnyguru was talking about the lower wattage CV models, which are group regulated. The 650W is not.

From the same Cybenetics report:

If you pay attention to context it would become apparent that Jon is talking about lower wattage, indeed group reg versions of CV.

Uh, i forgot about that, we even have a components breakdown there and no, it doesn't have 'very cheap and low-end Chinese capacitors'. It's a definitely not high-end PSU either, but for OP's needs it's more than enough and they already have it, no need to replace unless they plan to upgrade to much higher-end system.

He literally said he wants to upgrade to higher end components and overclock them. He literally said that a few hours ago. That's why I'm advocating for a future upgrade. I never told him to replace it asap, I told him to avoid pushing his system to the absolute max so that he can use that power supply till future upgrades

'GTX1660Ti and another stick of RAM' aren't higher-end components, and again overclock is irrelevant here as even maxed out under water these components would still consume rather mundane amounts of power where 40°C ambient 650W continuous rated, double-forward, DC-DC PSU would be more than enough, no 'absolute max's involved here. If and when they'll upgrade to higher-end system indeed, like OC'd i7 9700K / i9 9900k, perhaps smth AMD that actually OC's well from the future, mid/high-end GPU like RTX2070 and up - then upgrading a PSU too would make much more sense, especially since by that time all this current situation should resolve itself, prices would be lower and there would be actually smth in stock.

It most certainly does have OTP.  All Corsair PSUs have all protections, including OTP.

 

And yes... It's the lower wattages that are group regulated.  The 650W has DC to DC.  But all three wattages use double forward.
