How many watts does my psu have and do I have enough leads?

I have this PSU - CVS MP-700... guy in the shop told me it was 700watts and I thought overkill to replace my old TRUST 570 W... anyway (not much info about the CVS MP-700 around)

On the PSU label it says: CVS 700 :

3.3V - 15A , 5V - 16A, 12V1 - 23A, 12V2- 23A, -12V - 0.5A, 5V - 3A

So knowing not much I think ...

V A Watts 3.3V 15 =49
5V 16 =80 12V1 23 =276
12V2 23 =276
-12V 0.5 =6 5V 3 =15

Total Watts = 702

But I also think this is probably the maximum output and that to be on the safe side I should probably assume a safe output is more like 75% of this figure ... say 530 Watts ... Q 1 Am I right to think this ?

Also I am planning to get a bigger card - (current card has no 6/8 pin just off the mobo GTX 750 ti TDP 65 w) something like a GTX 1660 Ti TDP 120 Watts

I put a build together on pcpartpicker and it says the total wattage (including the new 1660 ti card) will be 302 watts - I did the same on another site and it came up with 300 watts too.

The CVS MP-700W psu only has 4 leads - 1 x 20+4 for mobo 2 x molex 4pin + sata 1 x 4pin - that goes to the mobo too - for nic maybe

So my plan is to put my ssd and hdd on one of the molex+sata leads and put the 8 pin to the new 1660 ti graphics card on the other molex+sata lead...

I don't see a big load being drawn from the molex because half the power will probably come from the mobo anyway... I am assuming mobo will give 60 watts and molex will do the same if it needs to.

Q2 Is this going to work ok - Am I right to think this ?

Thanks

What's your PC configuration, and from which country are you from?

Lets start from there.

And that seems like a potato PSU with these specs you mentioned above.

If you wanna purchase a new PSU just choose a branded one and not a no name one!

Budget zero - hoping I can make do with the CVS 700 ... hoping someone could help me understand why the CVS 700 cannot do the job :)

I'm sure The Corsair CX 550M @ 5,000 php is a good one

Maybe this Seasonic M12II EVO 520 @ 3,295 php is a better deal

If you can't to better, just get the Seasonic M12II EVO 520.

It would be way better than the Trust PSU unit you already have or that CVS 700 that you have in mind to purchase.

So this one.

Yah - but it's strange when I use the seasonic wattage calculator - tells me build will need 460 watts and then recommend I use a 650w psu ....

The SEASONIC ECO PLUS SERIES 500W POWER SUPPLY 80+ BRONZE is cheaper than the M1211 EVO 520 .... is that one no good - same bronze rating?

A build with a 1660 ti and a 95 TDP CPU will consume less than 300 watts.

The SEASONIC ECO PLUS SERIES 500W POWER SUPPLY 80+ BRONZE is cheaper than the M1211 EVO 520 .... is that one no good - same bronze rating?

Then get the Eco plus.
