SeaSonic M12II 750 or XFX XTR Series P1-650B?

[Amberr]

Hello! I have been around, asking a lot of questions and I am having to come up with my end build and I am looking at 2 PSUs. Both are $99 and I am wondering what one you all would get if you had to pick one, and why.

The M12II is 750W and it is 80 PLUS BRONZE Certified.

The XFX XTR one is 650W but it is 80 PLUS GOLD Certified. I really have no idea what that means to tell you the truth, bronze, gold. What is that all about? I know they are both made by SeaSonic, so they are high end PSUs. I am just not sure what one is better here.

XFX XTR Series is the better power supply.

Wattage - depends on your build.
Quality - See http://www.tomshardware.com/forum/id-2547993/psu-tier-list.html#xtor=EPR-8886 - they are both in tier 2
Efficiency - gold beats bronze.

If the 650 is OK per your build wattage then go for the XFX.

Okay, thank you. That leads me to my next question. Do you think that 650w will be enough? I am going to use a 4690k, an SSD and an HDD, An ASRock Fatal1ty Z97 Professional, and one GTX 970... though I would like to SLI down the road?

You will want 750 for the SLI.

Yes. In fact you could use a XFX550 without problems for one gtx970. But you'll need 750W for 2 of them. Usually we recommend the EVGA Supernova G2 gold 750.

3 for SLI , choose one

Okay, thank you all lots! It was really helpful. So, if it is not to hard to brake down, can you tell me what changes I would see between the two? They are both pretty good for the price point right? Does one just use up less power?

The EVGA G2 or XFX XTR 750 are 2 of the best , I would go EVGA G2 750.

The Gold versions will only save a few pennies on the e bill.
