I want to build an itx
Amd ryzen 3400g
8g ram
M2 nvme 512gb

Requires how much watt? In future maybe add dedicated graphic card. Not high end

Which dedicated GPU?

What's your case? That's going to limit your GPU choices and in turn, your PSU.

Without much info, you'll be fine with a 400W.

Jonsbo t8
Dunno what gpu.. maybe lower than 1k

Get a good SFX sized 450W PSU. You should have enough clearance for the stock heatsink (Height 54mm).

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

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

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

As others mentioned, the SF450 (RM450) from corsair would fit your needs. It is however, not an easy PSU to find in stock. You can go for an SF model that has offers higher watts like the SF600 (RM600) or SF750 (RM750).

An alternative would be the SX650-G (RM450) from Silverstone.

Can gip me the link both brand rm450? I searched hardly got sfx with lower watt

I sent you a PM.

Also, if you go for a higher watt PSU than you need I wouldnt worry too much about that if it's still within budget.

It's not going to ruin your parts because the PSU only supplies the amount that is being drawn by each part up to it's rating.
It doesnt overload parts with excessive watts.

Besides, PSU max effectiveness is when it is operating within 50 - 70% of it's rating.

Apparently newer models have better efficiency curves, according to Jon Gerow, so you should just get closer to what you need, and not paying more for larger wattage units. Just have to think of the future needs, eg adding or upgrading GPU

I have an used cooler master PSU 650w keep for 4 to 5 years already.. Would it be safe to use again or should I buy a new PSU instead?

Exact make and model of the Cooler Master PSU?

can anyone recommend me a good and cheap 750w psu for future proofing my pc

thanks in advance

There is no cheap if you want reliability. Super Flower Leadex II Gold 750W at RM439.

according to czone pricing corsair 750w is also the same price, would you recommend this or still the super flower one? how about silverstone et gold 750w priced at 339 and gs gold 439?

Super Flower has dual 8-pin for the CPU.

Silverstone PSUs has nothing to shout about for the performance.

which psu is suitable for my needs:

PC Spec:
ryzen 2700x
rx580 8gb
16gb 3000mhz ram



Gamdias Kratos P1-650G-650w
OVP/OCP/SCP/OPP/UVP/SP/ICP

SUPER FLOWER SILVER ECO 600W
OVP/OCP/SCP/OPP/UVP/OTP.


Originally plan to buy Gamdias Astrape P1 650w, since it is listed as a tier A PSU. Unfortunately i can't find it anywhere here.

How much are you willing to spend?

RM300 top

No reviews on the Gamdias, but it's an Andyson unit which is OK, but not great

The Super Flower gets my pick though
