Question  cpu power? by jamie

Does this PSU have 4+4 pin Motherboard power (or CPU Power)?

And would this PSU Fit and work with Gigabyte F2A78M-DS2?

Answer by shaund on Tuesday, June 16, 2015
Hi Jamie,

No this does not have 4+4 Power, the 'ARIAnet 500W APFC 85% Efficient 80+ Bronze Power Supply' does though however it is recommended to go for the 500w EVGA PSU.

Question  Question by HELP

Would this work with an EVGA GTX 750 1GB NVIDIA graphics card??

Answer by shaund on Saturday, May 9, 2015
No, it does not have enough PCI-E power cables nor enough molex connections for adapters.

Comment by hh

does this power supply work with bit fenix comrade black case?


Response by samuelm
It does.

Question  If not, why not? by Wakou

Do these have a 6 pin power out for a graphics card? If not, why not? The only reason for a PSU above about 300W is surely because people need to power a GPU? No-one has that many HDD or optical drives needing that much wattage (do they?) Is there any disadvantage/reason not to run a decent GPU card with a 2-molex> 6-pin converter?
Also, what is the REAL (operational) difference between a cheap PSU like this one, and one with similar wattage output costing 4 or more times the price? Is there any 'danger' to a Mobo or graphics card from using a cheaper PSU?

Answer by samuelm on Sunday, November 16, 2014
It does not have 6 or 8 pin connectors. The real operational differences over power supplies costing more are ultimately reliability and life span.
