Hello,

I have a new build as follows: (http://pcpartpicker.com/list/86FWNG)

Msi z170 A pc mate M0b0 (24 pin connector)
i5 6600 cpu
2x8 16 gb ddr 4 2133 mhz ram
850 evo ssd

No Graphics card. Planning to get one next year along with a new PSU that can go with it. Partpicker rates the wattage at 156, let's say it can go up to 250 under load (maybe more ? less ? not really educated on this matter). Meanwhile though, I'd like to keep the other hardware in one piece.

And the crux of the matter; my psu: Thermaltake XP550 PP 430W (W0095)

https://market.yandex.ru/product/1618252/spec?hid=857707&track=char

Not Russian, but for some reason only shows up on Russian sites on a search. I'm guessing it was a market specific product that somehow ended up in my case. It's an old PSU (at least 9 years) that has seen intermittent use. Back in the day I would've put thermaltake stuff in a system with my eyes closed, but I'm not so sure whether it's a good idea to couple it with the new components now.

And to make matters even more complicated (at least for my level of knowledge) it does not have a 24 pin connector, but a 20+4 pin as seen in the picture below. I would like to have a stable system with no reliability issues. If this is in any shape or form a hindrance, please let me know, and why. If it's not, I'd rather keep it and spend the cash on a mid to high quality PSU next year.

Thanks in advance to anyone who has a look or posts

The 20+4 pin connector is common, even on many modern PSUs.
If that Thermaltake is similar to their other 430W models from that time, it is low quality and not good for its label, but with no graphics card in your system, I believe will be okay. Just don't use it to power a graphics card, but replace it first.
While I would also suggest not using it, do note that 20+4-pin is very common.

The purpose was because motherboards used to be 20-pin then four connections were added so PSU's wanted backwards compatibility with the 20-pin motherboards. So the voltages are still correct.

It's funny you posted that in a way, because the vid is from 2008 and the thermaltake I have is from 2007. Thermaltake was "budget" at no time during that period, but I guess a case could be made that it is a low quality, insufficient psu for parts that came out mid 2015. And to be perfectly honest, that is what I was asking. The wattage is more than enough for the sysyem on paper at least.

Thanks to everyone for their answers. I'll plug it in and let you guys know if something goes pop ;)



When i buy a gpu next year, I will change the PSU %100. Provided this one doesn't fry anything until then :D

Lol it turns out my PSU doesn't even have an 8 pin power connector. This is definitely (unfortunately) something I had overlooked horribly. In the past, people have asked whether a 4 pin connector could be used instead, and some have answered yes. I must admit this is getting iffier by the moment.

Is it worth trying the 4 pin connector my PSU has, on the 8 pin connection on the M0b0 ? Or is it too much risk for the new parts ?
