Which PSU - Corsair vs Thermaltake?

[Cam P]

I am building a mini ITX gaming rig for about $900, but I don't know how much power I will need.

I am going to put in an Intel 6500 for the processor and a R9 Nano for the GPU, along with a regular 1TB 7200rpm HDD.

I've found two cheap power supplies:
Corsair 650W Modular bronze ($46)

and
Thermaltake 750W modular gold ($55)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817153198&utm_medium=Email&utm_source=IGNEFL041216&cm_mmc=EMC-IGNEFL041216-_-EMC-041216-Index-_-PowerSupplies-_-17153198-S4A9A

I also found this but its not modular so I think it will take up too much space and hinder airflow:

Both have good reviews, but how much power do I really need?

650W is enough, though for your build I'd recoomend getting the XFX (P1-650S-NLB9) 650W. It is considerd to be the best "budget" PSU.

 

[Dunlop0078]

I wouldn't buy either. I would recommend this below, an xfx like mentioned above wouldn't be bad either.

I'd take that over both those you listed.

@SkittishGaming The prices on that don't seem to drop very often:

The Corsair CX series have been found to be of poor quality. the Thermaltake is of decent quality, so either go with that one or an EVGA or one of the better XFX models.

What case are you getting? Some need an SFX power supply.

The evga GQ is the same platform as the FSP hydro I believe.

 

[turkey3_scratch]

I don't think it is. GQ performs much differently, worse actually. Hydro G and GQ are separate, I recall this from Jonnyguru forums.

 

[madmatt30]

^ Yep mate you're right , op seems unwilling to drop $80 on a PSU though , which I find daft with $500 worth of GPU in there.

GQ isn't bad still for $55 after rebate though in all honesty.

 

[turkey3_scratch]

Yeah the 650 GQ is alright; I sort of relate it to the 650 GS. I agree, he can drop $500 on a GPU, he should be able to buy a quality power supply at least $70. I'm guessing that $55 is also with rebates probably.

 

[superninja12]

gq is still a good unit imo
