Need advice on PSU

VulguM · Jul 7, 2016

Hello there, guys. I'm looking for some advice on PSU for the new rig I'm starting to build.
Long story short, my goal is to end up with:

CPU Intel i7 6700k
Mobo Asus Z170 Pro Gaming
16GB DDR4 RAM (2x8)
GPU Asus Strix GTX 1080
1 SSD 500GB Disk
1 HDD 2TB for Storage
4 Corsair 120mm fans and a Corsair H55 for cooling

Currently I'm lacking the GPU and I have an old (but I think reliable) CoolerMaster 600w PSU.
Thing is, the GPU needs a 6pin and a 8pin connector and my PSU only has two 6pins for PCIe.

So I'm thinking about getting a new PSU. What would you recommend? Would a ~600w fairly decent PSU be enough for this system?

Also, I'm from Argentina, so my options are quite limited as I have no access to really good PSUs (unless massively overpriced).

I was thinking about:
SEASONIC M12II 620w (or the 750w variant if needed)
Thermaltake Smart 750w
Corsair CX650M (or CX850M)

I'd like to get the best fit power and quality wise as I'm lacking budget atm.

Also, would be safe to use a two LP4 to 8pin adapter (or 6 to 8 pin adapter) as a temporary fix? If so, what would you recommend?.

Thanks for your time guys.

I would just get an adapter like this https://amzn.com/B001TK3TJY unless you really want a new psu I don't see why you should get one.

This may be ok, or pretty poor advice. It all depends which "coolermaster 600w PSU" you have OP. Some are good ,some are not very good at all, it depends on the model.

Generally speaking, if your PSU lacks the relevant connectors, any form of adapter is a bad idea.

A quality ~600W PSU should be more than sufficient for that setup.

As a (fairly) easy frame of reference, look here:
http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html
It's a little simplistic, but it'll get the job done.

You'll want a Tier 1 or Tier 2 PSU. I wouldn't recommend 3 or below. Pay close attention to the model(s), as going by brand alone is near impossible.

The SeaSonic M12II 620W would be my pick of the ones you suggested - the other two are pretty poor quality.
Take a look at the link though, you might be able to find some of the other options for a reasonable price.

Keep in mind, you don't want to 'cheap out' on your PSU - especially with such quality components.
You don't want to run your new, expensive components on a poor PSU as you can (in extreme situations) actually cause damage to the other components.

Hey. I'm reporting back with the exact model of my old PSU. I didn't include it in my first post because I wasn't able to remember the exact one.

So here it goes:
CoolerMaster RP-600-PCAR

I think it should run fine without the GPU (it will take some time to get the one I want).
Any advice much appreciated.

Thanks again, I'll keep an eye for your answers, guys.-

Yeah, it's not very good. http://www.hardwaresecrets.com/cooler-master-extreme-power-plus-600-w-power-supply-review/9/

Serious risk to your computer if it pulls over 450W.

It should be ok without the GPU, but when the time comes to add it, definitely invest in a quality PSU to go with it.

Alright, thanks for the input guys.
I'll get a Seasonic M12II EVO 750w just to stay on the overkill side in case I need more power down the road. Until then I'll run GPUless (no stock near the horizon yet anyway) with my current one.

Take care and thanks for your time.-
