1. FSP HYDRO GE 650W 80 PLUS GOLD FULL MODULAR
2. Super Flower Leadex Gold II 650W Full Modular PSU
3. Cooler Master MWE 650W 80+ Gold Full Modular
4. CORSAIR TX650M, 650W, 80+ Gold Certified, Semi Modular Power Supply

which one to get and why?

Either the Leadex II Gold or the Corsair - any one will do unless you need full modular cables icon_idea.gif

hope some sifu can enlighten me

full modular, semi modular & non modular PSU

what's the difference?
*
Full modular -> All cables can be removed from the unit
Semi modular -> Some cables can be removed, but some cable are permanently attached to the unit and cannot be removed
Non-modular -> No cables can be removed from the unit

Guys, are there any reliable power supply for 500W that is cheap (around RM1xx)?

My old FSP Hexa 500W which is already 7 years+ is so noisy now.

Cheap and quality doesn't really mix IMHO icon_idea.gif

Consider the EVGA 500BV if you are short on budget icon_idea.gif

Quality comes with the price. High quality electronic parts inside power supply does not come cheap. Most quality models will use Japanese capacitors. They are top quality.

Also, a RM400 650W weight is heavier than RM150 650W.
Just buy it. I think FSP is still the best low budget PSU.

...and often comes with modern circuitry as well icon_idea.gif

Despite power consumption of modern hardware has dropped significantly - it's still extremely important to spend a bit more on a proper PSU. Skimping on the PSU can have dangerous consequences (you may risk damaging the rest of the hardware if a cheap unit is used) icon_idea.gif

Those are made by HEC - not exactly the best OEM IMHO. Here's a review:

https://www.kitguru.net/components/power-su...upply-review/6/

Decent PSU when it comes to ripple/voltage regulation, but the use of low quality capacitors makes it a difficult recommendation sweat.gif

Not worth it IMHO - might as just pay a bit more for this instead:
https://www.lazada.com.my/products/evga-650...554bizbwEu&mp=1

There's a 550W variant - but the price gap is about RM30 icon_idea.gif

This unit uses Japanese main capacitors (not 100% though), and component quality is much better on the EVGA unit icon_idea.gif

It's made by FSP, which is a better OEM than HEC BTW icon_idea.gif

Awful bad sifoo. Japanese caps have high quality. I think got a few more non Japanese brand also good.

Yup some Taiwanese caps like newer Teapos are quite good icon_idea.gif

There's a very good reason why higher end units tend to come with full Japanese caps icon_idea.gif

Not much, maybe 20-30W at most in addition to your CPU+GPU power usage icon_idea.gif

What is the minimal psu watt to overclock rtx 2070 and ryzen 3800x
*
How much are you willing to overclock however? The Ryzen 3000 series however does not have too much overclocking potential (the boost clocks are more than enough for that, and even with manual overclocking the performance gains are too little)

For that, consider a high quality (preferably 80+ Gold rated) 650W unit or even a 750W unit. Look at the Corsair TX650M or the Super Flower Leadex II Gold 650W for starters icon_idea.gif

I'm in a midst of upgrading my rig atm which i bought in 2013. Currently using PSU Corsair TX750M 80+ Bronze
as this https://www.corsair.com/us/en/Categories/Pr...p/CP-9020040-NA

Should i buy a new PSU for my new rig or just use the current one? It's working okay btw.

My new rig
AMD RYZEN 5 3600 4.2GHZ SOCKET AM4
ASROCK B450M STEEL LEGEND SOCKET AM4 MAINBOARD
T-FORCE DELTA RGB 16GB (2X8GB) DDR4 3200MHZ
XPG 512GB SX8200 PRO NVME M.2 SOLID STATE DRIVE
AIGO DARKFLASH DLM23 TG M-ATX CHASSIS - WHITE

using back my 480gb SSD,1 TB sata HDD and RTX 2060 GB Zotac AMP

Thanks

Your unit should be fine - a quality 750W will basically powers most if not all single GPU setups icon_idea.gif

My Cooler Master UCP 1100W psu has now degraded after 9+ years of continuous 24/7 use. Plan to replace it with Cooler Master V1000.

Looking for better alternatives and suggestions if any before ordering one.

Specs of your machine first? I highly doubt you'll need a 1000W unit for modern hardware these days icon_idea.gif

Also, how much are you willing to spend? hmm.gif

According to Outervision PSU calculation for my needs and upcoming upgrade; Recommended PSU wattage is 825W and recommended PSU is: EVGA SuperNOVA 1000 G+, 80 Plus Gold 1000W.

Budget below MYR 800 should be good enough? 🤔
Among other things, when you have trouble cold booting the PC and both 8 pin power led on your primary GPU is blinking.
*
I wonder what setup you are running as 825W seems to suggest that you either run a HEDT platform or even a multi-GPU setup (which is very rare these days) along with heavy overclocking hmm.gif

Consider this?

I'm using Ryzen 3 3200g and RX 570 in my system.

Is this PSU good?

https://shopee.com.my/-FSP-HYDRO-GD-80-PLUS...7182.1491377688

I can't find any review for it. All the reviews available are for Hydro G or Hydro GE.

Alternatively should I go for this?

https://shopee.com.my/-SEASONIC-S12-II-430W...7182.1466019264

or this

https://shopee.com.my/Corsair-CX-M-Series-C...7888.1839186914

The Seasonic S12II is based on a very old platform so I can't really recommend it. Corsair's CXM series is not cheap and is not that good in terms of performance either, and it doesn't has 100% Japanese caps icon_idea.gif

Personally the Hydro GD should be a reasonably good buy - the Hydro platform is used on some EVGA units, and is proven to be a decent performer icon_idea.gif

According the to specs sheet it's highly recommended to get a SFX unit. The Corsair SF450 should be a decent pick icon_idea.gif

There's the RTX2060 Mini for RM1299 if you are willing to stretch your budget, or if you can't there's always the Gigabyte GTX1650 Mini for RM699 icon_idea.gif

The PSU should handle either of these GPUs quite well and should fit into the Jonsbo case you've mentioned icon_idea.gif
