Hi, need some recommendation here for future build:

Ryzen 5 5600/X
16GB Kingston HyperX Predator
1050 Ti
500GB HDD
256GB NVME

Is this one ok?
1) Silverstone Essential Gold 650W (PSU Tier List - B)

Or recommend me any somewhere RM300++ or below. Thanks

Looks alright I guess? hmm.gif

https://aphnetworks.com/reports/silverstone...et750-hg-750w/3

https://bit-tech.net/reviews/tech/psus/silv...-750w-review/1/

105C Japanese caps as the primary caps, which is better than the MWE Gold v1's 85C rated caps hmm.gif

650W is massively overkill for that machine though tongue.gif

There's also the Segotep GP600T though (note that this is a 500W unit, not 600W):
https://www.lazada.com.my/products/segotep-...HvbJ21&search=1

The Enermax Platimax DF mainly uses this platform, but with full Japanese caps instead of the Taiwanese caps you found in this Segotep unit (in fact the China domestic version uses CapXon caps instead of Teapos that we get here) icon_idea.gif

I think what I saw is a different version, not semi modular one.

https://shopee.com.my/Silverstone-Essential...3178.3321967840

Do you think the same caps used in this one? Good enough?
*
It's the same thing, the only difference is likely the modularity of the PSU icon_idea.gif

Note though, it's a low end unit with DC-DC (CWT GPN?), but it should be fine considering your machine doesn't consume that much power icon_idea.gif

myway1985 Seems like there are some new Super Flower PSUs:

http://www.jonnyguru.com/forums/showthread...-product-lineup

Also, any new PSUs coming to the local market? Seems like Singaporean retailers are now selling the new Legion GX/HX PSUs:

Seems like those units are quite decent value wise and would be a good competitor to the MWE Gold (and similar models) if it comes here hmm.gif

Hi, everyone, need a suggestion here. My PSU : Seasonic 620W is kinda old, almost reach 6 years already. Now to the PSU started to have this subtle buzzing sound, not sure what sound it is but it kinda annoying to leave the pc on idle but have that sound in my room. Below is my spec

Ryzen 7 3700X
MSI B550M Mortar
Corsair Dominator RGB 3200Mhz 8gbx4
Asus Strix GTX1070
Samsung 960EVO 500GB
HDD 1TB x 2
HDD 2TB x 1
SSHD 1TB x 1
4 Corsair LL120
2 Corsair stock fan
1 Corsair Lighting Node Pro
1 Corsair Lighting Hub

should I be worried of the sound coming from my psu ? If I were to change the PSU, which PSU is recommended thinking in future I might upgrade to a RTX3070 at least ?
*
Might be coil whine? (a recording would be useful here) hmm.gif

Coil whines are not something to be concerned about icon_idea.gif

If you plan to go for a 3070, look for a quality 550-650W unit, something in the line of the XPG Core Reactor/Enermax Revolution DF/Super Flower Leadex III/Corsair RM should do very nicely icon_idea.gif

here is the video [attachmentid=10723853]

i guessed it's a coil whine ? since it's a 620W psu, if I were to upgrade to a 3070, can it sustain the load ? or I should upgrade together with a new PSU, saw a shop at shopee sell the XPG Core Reactor 750W for RM458, is it a good price ?
*
Sounds like coil whine for me hmm.gif

Yes, it will handle a 3070, but do bear in mind that you might want to swap to a newer unit as yours is an old, group regulated unit, which isn't very suitable for modern systems anymore icon_idea.gif

The XPG Core Reactor is a great unit, so go for it if you can (although a 750W unit would be massively overkill for a 3070) icon_idea.gif

mind recommend between super flower leadex iii 650w gold vs xpg core reactor 650w ? which better for overclock amd 5600x & rtx 3070
*
Both are very high quality units, so pick the one that is cheaper of the lot icon_idea.gif

The Leadex III is a tier A+ unit (marked in gold in the PSU tier list), whereas the Core Reactor is a Tier A unit:

my suggestion is get the HIGHEST Powered with HIGHEST EFFICIENCY PSU you can afford.

PSU is NOT LIKE CPU/GFX card where you need to change often..

A good one can last you a LIFETIME...

FYI I've been using Seasonic 860W Platinum for >6 yrs ; and survived 3 generations of an upgrade of CPU&GPU.. it scales accordingly when  upgrade

You may regret getting 'just enough' for your current rig.. but ended up spending a new PSU when you upgrade your CPU/GPU in the next couple of years...
I did pay close to RM900 back then for this Platinum efficiency 860W PSU ; but I don't have to change 3x PSU and I saved upfront on bill electricity...
*
Efficiency =! performance mind you tongue.gif

There are lots of 80+ Gold/Platinum units that perform mediocrely icon_idea.gif

What really dictates the quality of the PSU is usually the quality of the components and the overall topology of the PSU itself (as a rule of thumb, always avoid any group regulated + double forward units, as those units are pretty much outdated for modern PCs) icon_idea.gif

Use the PSU tier list for a general idea of the PSU quality:

How much are you willing to spend though? hmm.gif

The new Super Flower units are quite decent:
https://www.lazada.com.my/products/super-fl...r6eCuZ&search=1

DC-DC + LLC topology along with Japanese main capacitors, and is a Tier B unit on the PSU tier list (low priority for now, due to a lack of reviews) icon_idea.gif

hi guys, need some help concerning PSU wattage, as previously I had seek some advice from facebook but then I think I may have gotten some wrong information. I bought 850W PSU for AMD Ryzen 5 3600 + RTX 3070 setup.
But when I use the PSU calculator from google, they mentioned I only need around 400W to power up my PC setup.

Will oversupply of Watt from PSU harm my PC? The PSU I bought is as per below

https://shopee.com.my/product/18789640/6717999372

No, the hardware will only draw the necessary watts needed from the PSU icon_idea.gif

You have a high quality unit, so don't worry wink.gif

Hi sifu-sifu here, recently I just RMA my new Corsair RM1000x which bought after My Seasonic X-650 kaput last year.

I have no idea which good brand to try anymore.
Any suggestion for good quality, Gold efficiency PSU with wattage 750-1000W?

Budget? and your PC specs right now? hmm.gif

Less than RM800 I guess. Gold efficiency series enough. Not going for high end Platimum. sweat.gif
I know Seasonic is the diamond among PSU but I am not sure for now. This is why I end up trying Corsair but got issue pula...

I am shamed to show this. Old rig. i7-3770k, GTX 1070, 1 SSD, 1 5.4k rpm HDD, 1 7.2k rpm HDD.
Maybe something future proof. I think higher watt would have lesser load on it even though my system won't consume much.

That's still a pretty capable machine though tongue.gif

Consider those units:

1. https://www.lazada.com.my/products/adata-xp...CycSkE&search=1 (XPG Core Reactor 750W)

2. https://www.lazada.com.my/products/fractal-...7312117nK9&mp=1 (Fractal Design ION+ Platinum)

3. https://www.lazada.com.my/products/super-fl...554biVOb2E&mp=1 (Super Flower Leadex III)

Those PSUs should easily handle your machine, and they can even handle a RTX3080 (famous for high power spikes) icon_idea.gif

Not all EVGA units are good, it is very dependent on what EVGA models you are buying icon_idea.gif

Same goes to other reputable brands like Seasonic/Super Flower as well icon_idea.gif

Hi guys,

Can you recommend me a PSU that is able to handle the RTX3060/RTX3060Ti? Looking to upgrade my current 500W Silverstone PSU that has lasted for 10 years  laugh.gif 

Tempted to get the XPG Core Reactor or RM650 but it is quite expensive, are there any more budget friendly options with Gold ratings? Thanks!

Consider these:

1. MWE Gold v2: https://www.lazada.com.my/products/cooler-m...evBkDP&search=1

2. NZXT C650 (Seasonic OEM): https://www.lazada.com.my/products/nzxt-c65...554bSaNWvo&mp=1

3. Super Flower Legion GX Pro: https://www.lazada.com.my/products/super-fl...8PRUlc&search=1

Thanks for the recommendations! The MWE Gold V2 is quite close to the RM650 price I am seeing on Shopee from PCByte. The RM650 is now RM399 on sale.

It seems like the MWE V2 650W is also not being offered by many seller currently haha. Many out of stocks, only few seller remain that have stocks.
*
Then the RM650 is perhaps the best choice out there, considering that the MWE Gold v2 is one tier lower than the RM icon_idea.gif

Is it common to have coil whine on a new PSU? It is a Silverstone ST65F-GS.

Edit: Tried upload .aac but doesn't work.

Yes, and unless the coil whine is very audible, this shouldn't be much of a problem icon_idea.gif

Only audible when I stick my ear near the PSU. But the sound is there even when the switch on PSU is off (wall plug power is on). This one is also ok?

It's fine too icon_idea.gif

Coil whine doesn't usually means a faulty PSU, mind you icon_idea.gif

Consider the MWE Bronze v2, as this PSU uses a modern DC-DC+LLC design (which is better than the FSP's Double forward + group regulated design):

80 Plus PSU with 5 years warranty, very reasonable pricing in my opinion.

I don't recommend the Hyper K as this is a group regulated unit:

https://docs.google.com/spreadsheets/d/1eL0...range=C418:D418

Reasons why you should not get a group regulated unit:
QUOTE
the main problem with group regulated units is that it regulates 12v and 5v together. as noted above these days the only big use for 5v is part of the motherboard and storage, which keeps the load on it quite low, while modern systems have the heaviest components on 12v. In the PSU world we use the word "crossload" for loading up one rail a lot, while the others little to none (either from 3.3/5/12v). When the 12v is loaded up far enough, the controller can't keep the 5v in control, as they're reported together and starts to go out of ATX specification as the controller thinks it's only rising the 12v. especially since some of the units above don't have undervoltage protection, this can have results from shorter lifespan of components to in very bad cases burnt cables. ATX specification only allows a difference up to 5% between rails. They can also fail ATX specification easily when the minor (3.3/5v) are loaded up, while the 12v is kept at the minimal 0.1a
