Quick Power Supply Question

[Garee]

Will a 400W Corsair PSU be able to run a 1090T and a 5870 or will I need to upgrade?

Thanks!

ATI Radeon™ HD5870 System Requirements

• PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
• 500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode)

NOTE - These are the power supply recommendations for an entire pc system.

Id get at least...

TBH I think a 400W PSU would be a tad light for a system with a 1090T and a 5870.

Gaming load woud peak somewhere around 300W.
But I would avoid running FurMark and Linpack at the same time...

Barely any better with cheap caps in there.

A 400W will work, end of. ATI and Nvidia (lol) overspec the amount of watts you need because people usually try to use generic PSU's which aren't capable of putting out their rated wattage.

Wont work on the CX430 though... it's a 300w PSU in disguise and the older CX400 is light years better.
