Hi all

I have been given 2 x 400w power supplies, one Zalman ZM400-le (dual 6 pin) and the other Cooler Master RS-400-PSAR-i3 (single 6 pin).

The brightest answer is to buy a new power supply but funds are limited and I was given most of this hardware and am trying to get the best value for a system for myself and one to sell to save up for future upgrades.

List of how the hardware is configured at the moment.

Keep system
i7-870
Intel DH55TC motherboard
Maelstrom 120T AIO liquid cooler
14gb DDR3 ram
GTX 960 - single 6 pin
Samsung 840 evo SSD

Sell system
i5-760
HP OEM - MSI MS-7613 motherboard
Stock cooler
6gb DDR3 ram
GTX 560ti - dual 6 pin
Toshiba MK6475GSX 640GB - laptop hard drive

My thoughts are
-The sell system (against all online advise) is to get 2 x molex to 6 pin adapter.
or
-Use the Zalman power supply on the sell system as it has the dual 6 pin and use the Cooler Master on the keep system as the power supply only has single 6 pin and the GTX 960 only requires single 6 pin

Use case for the keep system is generally light gaming, currently maybe 2 hours of Starcraft 2 per day but may get into GTA V in the near future. Very limited overclocking as restricted by the board unable to adjust V-Core.

Use case for the sell system, I want to advertise it as a beginners/light gaming PC.

Thanks in advance
