I don't think it's a Super Flower unit - it's likely to be a FSP unit to say the least

The Leadex II Gold is actually better although the EVGA is no slouch either

There are actually two variants of the TX650M - one that is made by CWT (80+ Bronze), another is made by Great Wall (80+ Gold)

It's a very good unit, although the voltage regulation is not as nice as Seasonic/Super Flower

Unfortunately the TX650M is pretty noisy:

The Leadex II Gold is actually better - it's essentially a rebadged EVGA G3 650W, which is 1 tier up compared to the G1+

Answering your question - it's will work just fine

You can even power up a GTX1050Ti with a 300W unit

Which V850/V1000? Because there are two variants of them, of which one of them is made by Enhance rather than Seasonic

Most laptop power adapters are multi-voltage capable these days due to the fact that laptops are meant to be portable - if not that kind of limits the versatility of a laptop

The only thing he needs is a plug adapter

Like what TristanX said, it is multi-voltage capable, and thus you'll likely need a PSU cable (formally known as the IEC C13/C14 cable) with a US type plug (US/Canada/Japan/Taiwan uses the US-type plug, just for your information)

I cannot guarantee the reliability of plug adapters as it might not be able to handle the wattage, and thus a new power cable should be a better idea

Also, depending on which region of Japan you are living - you'll have to either deal with 50Hz power frequency (similar to Europe, and here) or 60Hz (similar to the US)

That's not too much problem consider the fact that most multivoltage capable PSUs will always have multifrequency capabilities

Of course, if you want to double confirm, just take a photo of the PSU label - it should say what voltage/frequency the unit supports. Some PSUs will label its input voltage right behind the PSU

Which model?

I haven't heard of this brand for quite some time now... They used to be quite good since some of their units are made by Seasonic, but I think their new units are not too good quality-wise:
https://www.tomshardware.com/reviews/pc-pow...w-psu,5871.html

These are made by Sirfa/Highpower, and the reviews are not encouraging to say the least

TristanX The upcoming Seasonic S12III is actually one of the first Seasonic-branded PSUs that are not manufactured by Seasonic themselves:

http://www.jonnyguru.com/forums/showthread...C-finally/page2

Grab something like an entry-level EVGA 450-500W unit and you'll be fine

Do you intend to use a discrete GPU?

Same here - it's obvious that they are slacking off due to very few competition (only Super Flower only can match Seasonic quality-wise)

Let's just hope that other OEMs such as FSP/CWT or even Great Wall can come up with a platform that can compete with Seasonic's quality

TristanX NZXT seems to have launched their E series PSUs (made by Seasonic) here:
https://www.lazada.com.my/products/nzxt-e85...554bSnyLwy&mp=1

It's essentially a Seasonic Focus Plus Gold with digital monitoring built-in

Although Tom's Hardware reviews are not exactly promising
https://www.tomshardware.com/reviews/nzxt-e...w-psu,5802.html

That's actually incorrect - the PSU will only supply the wattage needed by the system

In fact a quality, higher wattage unit can be beneficial due to the fact that the PSU is less stressed, which means better longevity. It also means that the fans will spin at a lower speed, contributing to lower noise

Depends on the make and model of the unit

An auto-shutdown due to bad current flow is definitely possible if your unit has some form of protection, such as over-current protection (OCP)

The TX650M (Great Wall OEM, custom design by Corsair) and the Leadex II Gold have very similar performance and pricing

EVGA rebrands the Leadex II Gold as their G3 PSUs (with some minor modifications), and it is considered one of the best PSUs at this price point

The CX550M is actually a step down from the Silver ECO you have there

Either RMA the unit, or increase your budget to something better

Also is it some kind of electrical buzzing sound? Because it might be capacitor whine and it is normal unless the noise is excessive

Should be coil whine or something - is it very loud?

If it's very loud then it might be a good idea to send it back for RMA

The EVGA G+ 650W gets reviewed on Expreview:

https://www.expreview.com/65731.html

The reviews is in Chinese (you may need to use Google Translate if you can't read Chinese), but in summary:

1. FSP is the OEM behind the unit
2. Japanese main capacitors (Chemi-con)
3. Japanese secondary capacitors (Rubycon/Chemi-con)
4. Very good voltage regulation on +12V, +5V and +3.3V rail
5. Ripple is very good on the +12V rail, but ripple on the +3.3V and +5V rail can be improved (about 23mV and 24mV, but still very much within the 50mV limit set by Intel)
6. Hold-up time is very good

Overall it's a very good unit, with the minor problem being ripple performance on the +3.3V and the +5V rail (again, not a problem as it is still within Intel's standard)

Either the Leadex II Gold, or the TX650M

Choose whether which one is cheaper

It's a good unit, but for that pricing - you can get a better priced unit (and likely better performing):

https://www.lazada.com.my/products/super-fl...554bm7RT1G&mp=1

The Super Flower unit I've linked above is rebadged by EVGA as their SuperNova G3 unit

Also, a RTX 2070 does not consume a lot of power - you can even step it down to a 550W/600W quality unit and it will likely do just fine, although if you intend to overclock then you may want a 650W unit for additional headroom
